In iMaster NCE-Campus–based virtualized campus networks, thesiteis a fundamental management object used to organize and manage network resources. A site typically represents aphysical location or logical network scope, such as a campus, building, or branch, under a tenant. Tenants manage devices, configurations, and servicesby site, which makes statementB correct.

iMaster NCE-Campus allows administrators tocreate sites individually, enabling flexible deployment and incremental network construction. Therefore,statement C is correct. In addition, a site is created and owned by atenant administratorto represent the tenant’s network scope, makingstatement D correct.

StatementA is false. iMaster NCE-Campusdoes support batch site creation, which is commonly used in large-scale or MSP scenarios where many tenant sites or branch sites need to be deployed efficiently. Batch creation significantly reduces manual workload and improves deployment efficiency.

According to HCIP Datacom Campus Network documentation, site management supports bothsingle-site creation and batch site creation, enabling scalable and centralized O&M. Therefore, the statement claiming that batch site creation is not supported is incorrect.

iMaster NCE-Campus is Huawei’s centralized management and control platform specifically designed forcampus network scenarios. According to HCIP Datacom Campus Network documentation, its primary purpose is to provide unified planning, automated deployment, policy control, and intelligent O&M for campus environments. Therefore,campus networksare one of the most typical and core deployment scenarios for iMaster NCE-Campus.

In addition, iMaster NCE-Campus is widely used to deployVXLAN Fabric networkswithin campuses. VXLAN Fabric is a key technology for building scalable, virtualized, and multi-tenant campus networks. iMaster NCE-Campus simplifies VXLAN Fabric deployment by automating underlay and overlay configuration, VN creation, VNI assignment, and BGP EVPN policy distribution. This makes VXLAN Fabric networks another standard and typical deployment scenario supported by the platform.

Branch networksare not considered a typical deployment scenario for iMaster NCE-Campus. Branch network management is usually handled by iMaster NCE-WAN in SD-WAN solutions, which focuses on WAN connectivity, branch access, and centralized WAN control rather than campus-oriented services.

Similarly,small-sized networksare not defined as a deployment scenario category in iMaster NCE-Campus documentation. The platform is designed for medium to large campus environments where centralized management and automation provide the most value.

Therefore, the typical deployment scenarios when using iMaster NCE-Campus areCampus networksandVXLAN Fabric networks, making optionsA and Bthe correct answers.

iMaster NCE-Campus classifies network alarms into different severity levels to help administrators quickly understand the health status of the campus network and take appropriate actions. According to HCIP Datacom Campus Network documentation, alarms are typically categorized intocritical,major,warning, andinformationallevels, each represented by a distinct icon and color in the management interface.

In the displayed alarm summary, four types of icons are shown with corresponding numbers. Thered flame iconrepresents critical alarms, and the number next to it is0, indicating no critical alarms. Theorange lightning iconrepresents major alarms, and the number displayed is5, indicating five major alarms. Theyellow exclamation mark iconrepresentswarning alarms, and the number next to it is1. Finally, theblue information iconrepresents informational alarms, with a total of10.

Warning alarms indicate potential issues that do not immediately affect network operation but may develop into more serious problems if not addressed. These alarms require administrator attention but are less urgent than critical or major alarms. Accurately identifying the number of warning alarms helps prioritize troubleshooting and maintenance tasks.

Since the yellow warning icon shows the number1, this means there isone warning alarmcurrently generated on the network. Therefore, the correct answer is1, corresponding to optionB.

HuaweiCloudEngine S series switchesare designed for modern campus access scenarios that require flexible device deployment, especially for wireless APs, IP phones, cameras, and IoT terminals. According to HCIP Datacom Campus Network documentation, these switches supportPoE long-distance power supply, allowing power and data to be transmitted overCat5e Ethernet cables for distances of up to 200 metersunder specific conditions.

Traditionally, standard Ethernet transmission and PoE delivery are limited to 100 meters. However, Huawei CloudEngine S series switches introducePoE Long Distance (PoE LD) mode, which extends the maximum transmission distance while maintaining stable power delivery and communication. This capability is particularly valuable in campus environments such as schools, hospitals, warehouses, and outdoor corridors, where powered devices may be located far from access switches.

When PoE long-distance mode is enabled, the switch optimizes signal transmission and power output to ensure reliable operation over extended cabling. This reduces the need for additional intermediate switches or power supplies, simplifying network architecture and lowering deployment and maintenance costs.

It is important to note that this feature applies to supported CloudEngine S models and compliant powered devices, and appropriate cable quality such as Cat5e is required. Within these design constraints, CloudEngine S series switches are fully capable of delivering PoE over distances up to 200 meters.

Therefore, the statement is correct, and the answer isTRUE.

In Huawei iMaster NCE-Campus and CloudCampus management systems, different log types are designed to record different categories of events to support auditing, troubleshooting, and security analysis. When anMSP administrator creates a tenant account, this action is considered amanagement operationperformed through the system’s management interface.

Such administrative actions are recorded in theOperation Log. Operation logs documentuser-initiated configuration and management activities, including tenant creation, modification, deletion, policy changes, and administrative actions performed by operators or administrators. These logs are essential for operation auditing and responsibility tracing in multi-tenant environments.

System logsmainly record internal system events, such as service startup, module status changes, or system exceptions, and do not track administrator operations.Security logsfocus on security-related events, such as login failures, abnormal access attempts, or permission violations, rather than routine administrative operations.Device channel logsrecord communication events between devices and controllers, such as device registration or channel status changes, and are unrelated to tenant management actions.

According to HCIP Datacom Campus Network and CloudCampus O&M documentation, tenant account creation performed by an MSP administrator is clearly categorized as anoperation behavior, and therefore it is recorded in theOperation Log.

In IPsec, bothAuthentication Header (AH)andEncapsulating Security Payload (ESP)are implemented as IP protocols and are identified by specificIP protocol numbersin the IP header. These protocol numbers allow receiving devices to determine how the packet payload should be processed.

The protocol number assigned toAH is 51. AH provides data origin authentication, data integrity, and anti-replay protection but does not offer encryption. When an IP packet contains AH, the protocol field in the IP header is set to 51 so that the receiver can correctly process the AH header.

The protocol number assigned toESP is 50. ESP provides data confidentiality through encryption and can also provide integrity and authentication. Packets protected by ESP use protocol number 50 in the IP header.

The other options are incorrect because protocol number6represents TCP and17represents UDP, which are transport-layer protocols rather than IPsec protocols. Protocol number57is unrelated to IPsec.

According to HCIP Datacom Campus Network documentation and standard IP protocol assignments, the correct protocol numbers are AH = 51 and ESP = 50, making option B the correct answer.

According to HCIP Datacom Campus Network architecture principles, campus networks can be classified from multiple dimensions to support scientific planning, design, and deployment. These classification methods help network designers select appropriate architectures, devices, and technologies based on actual service requirements.

Network scaleis a primary classification dimension. Campus networks are commonly divided into small, medium, and large-scale networks based on the number of users, terminals, access points, and network devices. This classification directly influences topology design, such as whether a simple two-layer architecture or a more scalable three-layer architecture is required.

Served objectsis another important classification method. Campus networks may serve office users, guests, teaching staff, students, production terminals, IoT devices, or video surveillance systems. Different served objects have different requirements for bandwidth, security, and access control, making this dimension critical for policy and service design.

Access moderefers to how users and devices connect to the campus network, including wired access, wireless access, or a hybrid of both. This classification impacts WLAN planning, authentication methods, and network access control strategies.

Service complexityreflects the types and number of services carried by the network. A campus network may provide basic data services or support complex services such as voice, video, cloud access, and industry applications. Higher service complexity requires more advanced network design and management capabilities.

Therefore, all listed options are valid classification methods for campus networks.

In HCIP Datacom Campus Network VXLAN architecture, VXLAN tunnels are classified based onhow the tunnel endpoints are created and maintained, which is referred to as the VXLAN tunnel creation mode. According to Huawei VXLAN design principles, there aretwo valid VXLAN tunnel types: static VXLAN tunnels and dynamic VXLAN tunnels.

Astatic VXLAN tunnelis manually configured by an administrator. In this mode, the source VTEP IP address, destination VTEP IP address, and related parameters are explicitly specified on devices. Static VXLAN tunnels are typically used in small-scale networks or test environments where the number of VTEPs is limited and network topology is simple. However, static configuration lacks scalability and flexibility, making it unsuitable for large campus fabrics.

Adynamic VXLAN tunnelis automatically created based on control-plane learning mechanisms, such asBGP EVPN. In this mode, VTEPs learn remote VTEP IP addresses dynamically through EVPN route advertisements (for example, Type 3 routes). When a remote VTEP becomes reachable at the underlay Layer 3 level, the VXLAN tunnel is automatically established without manual intervention. This mode is widely used in modern campus and data center networks due to its scalability and automation capabilities.

Options A and D are incorrect becausestatelessandstatefulare not official VXLAN tunnel creation classifications in Huawei’s VXLAN implementation. VXLAN itself is an encapsulation mechanism, and tunnel state is not categorized in this manner.

Therefore, the correct VXLAN tunnel types based on creation mode arestatic VXLAN tunnels and dynamic VXLAN tunnels.

In the Huawei CloudCampus Solution, devices such as switches and APs support multipleprovisioning modesto integrate with iMaster NCE-Campus, including Web interface provisioning, CLI-based provisioning, and registration center query. These methods allow devices to obtain controller information and register successfully.

Firewalls, however, have stricter provisioning mechanisms due to security considerations. They do not supportDHCP Option 148, which is commonly used by switches and APs to automatically discover the management controller.

Instead, firewalls must be provisioned manually through the Web interface or CLI, or discovered via registration center mechanisms. According to HCIP Datacom Campus Network documentation,DHCP Option 148 is not supported by firewalls, makingoption Cthe correct answer.

The Huawei CloudCampus Solution adopts afour-layer architecture, not a three-layer one. According to HCIP Datacom Campus Network documentation, the architecture consists of theterminal layer,network layer,management and control layer, andapplication layer.

Theterminal layerincludes user devices such as PCs, mobile terminals, IoT devices, and other endpoints that access the campus network. Thenetwork layeris responsible for data forwarding and includes access, aggregation, and core network devices. Themanagement and control layer, represented by platforms such as iMaster NCE-Campus, provides centralized management, automation, policy control, and orchestration. Theapplication layerdelivers value-added services and business applications.

Because the terminal layer is an essential and explicitly defined component of the CloudCampus architecture, stating that the solution has only three layers is incorrect. Therefore, the statement isFALSE, making optionBthe correct answer.

In a Huawei VXLAN BGP EVPN architecture,Route Targets (RTs)play a critical role in controlling route import and export between VPN instances on different VTEPs. When a BGP EVPN route is received by a VTEP, the device determines whether the route should be accepted or discarded based on RT matching rules.

According to HCIP Datacom Campus Network documentation, a received EVPN route is considered validas long as its RT matches either the EVPN Import Route Target (EVPN IRT) or the IP VPN Import Route Target (IP VPN IRT)configured on the local device. This design enables flexible route sharing between Layer 2 EVPN services and Layer 3 VPN services, supporting integrated routing and bridging (IRB) scenarios and inter-VNI communication.

If the RT carried in the EVPN route matches at least one of these import RTs, the route is imported into the corresponding VPN instance and can be used for traffic forwarding. Only when the RT doesnot match both the EVPN IRT and the IP VPN IRTwill the route be discarded. This mechanism ensures proper isolation between tenants while still allowing controlled route exchange where required.

Therefore, the statement accurately describes the EVPN route filtering logic used between VTEPs in Huawei VXLAN networks. The route is discardedonly when the RT differs from both configured import RTs, making the statementTRUE.

In small- and medium-sized campus networks, the Huawei CloudCampus Solution focuses onsimple, flexible, and easy-to-manage traffic control mechanismsthat align with wireless access characteristics. According to HCIP Datacom Campus Network documentation, several rate limiting modes are supported to ensure fair bandwidth usage and stable user experience in WLAN environments.

Radio-based rate limitingis supported and commonly used in small and medium campuses. This mode limits the total bandwidth available on a radio interface, preventing congestion when multiple users access the same radio. It is especially effective in high-density wireless scenarios where multiple terminals compete for limited wireless resources.

SSID-based rate limitingis also supported. This allows administrators to limit bandwidth per SSID, ensuring that different wireless services—such as guest access and internal employee access—receive appropriate bandwidth allocations. This method is easy to configure and aligns well with service-oriented WLAN design.

User-based rate limitingis another supported mode. It enables bandwidth control on a per-user basis, ensuring fair usage among users and preventing individual users from consuming excessive bandwidth. This approach is particularly useful in environments like classrooms, retail stores, or offices.

ACL-based rate limiting, however, is not typically used or recommended in small- and medium-sized CloudCampus WLAN scenarios. ACL-based rate limiting is more complex and is generally applied in wired or advanced traffic engineering environments rather than simplified campus WLAN deployments.

Therefore, the supported rate limiting modes areRadio-based,SSID-based, andUser-based, makingA, C, and Dthe correct answers.

Encapsulating Security Payload (ESP) is one of the core protocols of the IPsec framework and is widely used in Huawei campus and SD-WAN network solutions to provide secure data transmission. ESP operates directly over IP and is identified by a uniqueIP protocol number, which allows network devices to recognize and process ESP packets correctly.

According to HCIP Datacom Campus Network documentation and standard IP protocol definitions,ESP uses protocol number 50. ESP provides essential security services such as data confidentiality through encryption, data integrity verification, authentication, and anti-replay protection. It can operate in bothtransport modeandtunnel mode, making it suitable for scenarios such as site-to-site VPNs and remote access VPNs.

The other options listed are incorrect.Protocol number 47is used by GRE (Generic Routing Encapsulation), which is a tunneling protocol and does not provide encryption.Protocol number 51is assigned to AH (Authentication Header), another IPsec protocol that provides integrity and authentication but does not support encryption.Protocol number 102is not associated with ESP or commonly used IPsec-related protocols.

Correct identification of ESP traffic using protocol number 50 is critical for firewall configuration, security policy enforcement, and proper forwarding of encrypted traffic in campus and WAN environments. Therefore, the correct answer is50, which corresponds to optionB.

In the Huawei CloudCampus Solution, access points can operate in different modes depending on network size, architecture, and management requirements. For asmall- or medium-sized campus networkwhere asingle AP is used as the network egressand must becentrally managed by iMaster NCE-Campus, the recommended operating mode isCloud mode.

When an AP works inCloud mode, it establishes a direct management connection with iMaster NCE-Campus through the cloud. The AP can independently provide wireless access services while also performing gateway and egress functions, such as user traffic forwarding and policy enforcement. This eliminates the need to deploy a dedicated wireless AC or additional gateway devices, significantly simplifying network architecture and reducing deployment cost.

Fit modeAPs rely on a local or centralized AC for control and therefore cannot independently function as a network egress.RU modeis used only in Agile Distributed Wi-Fi scenarios and depends on a central AP, making it unsuitable for this scenario.Fat modeAPs can operate independently but lack deep integration with iMaster NCE-Campus for cloud-based centralized management and automated service provisioning.

HCIP Datacom Campus Network documentation highlights Cloud APs as the optimal choice for small and medium campuses that require simplified deployment, cloud-based management, and integrated gateway capabilities. Therefore, to meet both the management and egress requirements described, the AP should operate inCloud mode.

Hence, the correct answer isC.

In Huawei campus networks, access authentication and authorization are implemented based on the AAA framework. After a user is successfully authenticated, the network enforces anauthorization result, which defines what network resources the user is allowed to access and how traffic is controlled. These authorization results are typically delivered by the authentication server or configured locally on network devices.

According to HCIP Datacom Campus Network documentation,authorization results focus on policy and access control attributes, not basic network parameter assignment. Common authorization items includeVLAN assignment,security group assignment, andACL application. VLANs determine the user’s logical network location, security groups enable group-based policy control, and ACLs restrict or permit traffic based on predefined rules. These elements directly affect access permissions and security enforcement.

AnIP address, however, does not need to be defined in the authorization result. In campus networks, IP addresses are usually assigned dynamically throughDHCP, either by a DHCP server or a DHCP relay function on network devices. The IP address allocation process is independent of user authorization and does not represent an access control policy.

Separating IP address assignment from authorization simplifies network design and improves scalability. It allows users to obtain IP addresses automatically while access rights are enforced consistently through identity-based policies. Therefore, among the given options,IP addressis not an item that must be defined in the authorization result.

Hence, the correct answer isB.

Comprehensive and Detailed Explanation (200–250 words):

In an iMaster NCE-Campus policy control matrix, rows representsource security groupsand columns representdestination security groups. A green check mark indicates that communication is allowed, while a red cross indicates that communication is denied. This matrix enables fine-grained user access control in VXLAN-based virtualized campus networks.

From the figure, communication betweenGuest_Group and Research_Groupis explicitly denied in both directions, as indicated by red crosses. Therefore, statementsAandDare both correct. The matrix also shows a green check mark forSales_Group communicating with itself, meaning intra-group communication is permitted, makingstatement B correct.

Theunknowngroup represents users that are not classified into Guest_Group, Research_Group, or Sales_Group. In the matrix, the unknown group is not completely blocked from all resources by default; access behavior depends on explicit policy configuration. Since the figure does not indicate a universal deny policy for unknown users toward all destinations,statement C is incorrect.

According to HCIP Datacom Campus Network policy control design, security group–based access control allows administrators to precisely define which user groups can communicate, improving security and service isolation. Hence, the correct answers areA, B, and D.

In iMaster NCE-Campus–based virtualized campus networks,user network segmentsare logical subnets created within aVirtual Network (VN)to provide Layer 2 or Layer 3 connectivity for users. HCIP Datacom Campus Network documentation describes multiple flexible methods for creating these network segments during VN deployment, allowing administrators to balance efficiency and control.

Administrators canmanually create user network segments one by one, which is suitable for small-scale deployments or scenarios requiring precise customization of subnet parameters such as gateway address, VLAN, and IP pool. This method provides maximum control but is less efficient for large networks.

For medium- or large-scale deployments,batch import using templatesis widely supported and recommended. Templates allow administrators to define network segment parameters in advance and import multiple segments at once, significantly improving deployment efficiency and reducing configuration errors.

Another supported method isautomatic batch allocation, where iMaster NCE-Campus automatically allocates VNIs, VLANs, and IP resources from predefined resource pools. This method is commonly used in VXLAN Fabric deployments and enables fast, standardized VN provisioning with minimal manual input.

However,directly invoking user network segments from the global fabric resource poolis not supported during VN creation. The global resource pool is used for automatic allocation reference but does not allow direct binding of pre-created segments to a VN.

Therefore, the valid methods aremanual creation,template-based batch import, andautomatic batch allocation, making optionsA, B, and Dcorrect.

IPsec defines two standard encapsulation modes that determine how IP packets are protected during transmission:Tunnel modeandTransport mode. Tunnel mode encapsulates the entire original IP packet within a new IP header and is typically used forsite-to-site VPNs. Transport mode encrypts only the payload of the IP packet and is commonly used forhost-to-host communication.

Switching mode and routing mode are not valid IPsec encapsulation modes and are unrelated to IPsec protocol behavior.

According to HCIP Datacom Campus Network documentation, onlyTunnel mode and Transport modeare supported in IPsec, makingoptions B and C correct.

Huawei CloudCampus is an intelligent campus network solution designed to simplify deployment, improve O&M efficiency, and enhance user experience through cloud-based and automated technologies. Its advantages mainly focus onnetwork automation, unified management of campus network devices, and intelligent services, rather than full IT infrastructure management.

Option A is a core advantage of CloudCampus. Through cloud-based controllers and automation technologies, CloudCampus supportsautomatic deployment of physical networks, reducing manual configuration and shortening service rollout time.

Option B is also an important advantage. CloudCampus supportsplug-and-play of devices, where network devices can automatically go online, download configurations, and complete provisioning after being powered on and connected, significantly reducing on-site workload.

Option D is another key feature. Cloud Campus supportsfree mobility, allowing users to roam across different access points or areas while maintaining consistent network access policies and service experience, which is especially important in modern wireless campus environments.

Option C isnot an advantageof the Huawei Cloud Campus solution. Cloud Campus focuses on unified management ofcampus network devicessuch as switches, routers, and wireless devices. It does not provide unified management forstorage servers, which fall outside the scope of campus network management and belong to data center or IT infrastructure management solutions.

Therefore, unified management of Huawei switches, routers, and storage servers is not an advantage of the Cloud Campus solution.

Huawei campus switches support multiple flexible VLAN assignment methods to meet diverse access control and service deployment requirements. The most basic method isinterface-based VLAN assignment, where a physical or logical port is statically assigned to a specific VLAN. This method is simple and widely used in traditional access layer designs.

Huawei switches also supportMAC address–based VLAN assignment, allowing devices to be dynamically placed into VLANs based on their MAC addresses. This is useful in scenarios where users frequently move between access ports but require consistent VLAN membership.

Protocol-based VLAN assignmentenables traffic to be classified into VLANs based on upper-layer protocol types, which can be useful in special service separation scenarios. Additionally,IP subnet–based VLAN assignmentallows switches to assign VLANs according to the source IP address of packets, enabling logical grouping of users based on network layer addressing rather than physical location.

These VLAN assignment mechanisms enhance network flexibility, simplify user mobility, and improve access-layer service management. According to HCIP Datacom Campus Network documentation, Huawei switches indeed support VLAN assignment based on interface, MAC address, protocol, and IP address. Therefore, the statement is TRUE, and option A is correct.

Authentication Header (AH) is one of the core IPsec security protocols and is designed to provideauthentication and integrity protectionfor IP packets. AH ensures that the received packet is from a legitimate sender and that the packet has not been altered during transmission.

AH supportsdata origin authenticationby verifying the identity of the sender using cryptographic algorithms. It also providesdata integrity checking, ensuring that packet contents are not modified in transit. Additionally, AH supportsanti-replay protectionby using sequence numbers to prevent attackers from capturing and retransmitting valid packets.

However, AHdoes not provide data encryption. All packet contents, including payload data, remain visible on the network. This limitation is inherent to the AH protocol design and is one of the main reasons ESP is more widely used in modern IPsec deployments.

According to HCIP Datacom Campus Network documentation, if confidentiality through encryption is required, ESP must be used instead of AH. Therefore, the function not supported by AH is data encryption, making option D the correct answer.

In a CloudCampus VXLAN fabric, theglobal resource poolcentrally manages identifiers such as VLANs, VNIs, and bridge domains to ensure consistent allocation across the fabric.

StatementAis correct because abridge domain (BD)is the VXLAN equivalent of a VLAN and represents a Layer 2 broadcast domain used for packet forwarding within a VXLAN network.

StatementCis also correct. AVXLAN Network Identifier (VNI)uniquely identifies a VXLAN segment and is a core VXLAN forwarding identifier.

StatementDis correct because theservice VLAN poolis used to allocate VLANs for multiple purposes, including external gateway interconnections, network service resource interconnections, policy association management, and VN access VLANs.

StatementBis false. VLANs used forunderlay device interconnectionsarenot allocated from the VLAN resource poolmanaged by the VXLAN fabric. Underlay VLANs belong to the traditional IP underlay network and are typically planned and configured independently. The VLAN resource pool is intended for overlay-related services and fabric-managed VLAN usage only.

Therefore, the incorrect statement isB.

Administrator:

– Defining a Security Group

– Defining a Policy Control Matrix

iMaster NCE-Campus:

– Delivering IP-Group Entries

– Delivering a Policy Control Matrix

In Huawei’s free mobility solution, responsibilities are clearly divided betweenadministratorsandiMaster NCE-Campusto achieve centralized control with automated policy delivery. Administrators are responsible forpolicy and security intent definition, while iMaster NCE-Campus handlesautomatic distribution and enforcement coordination.

Administrators firstdefine security groups, which represent logical user or terminal categories such as employees, guests, or IoT devices. These security groups form the basis of identity-based access control in the campus network. Administrators alsodefine the policy control matrix, which specifies communication permissions between different security groups, such as allow, deny, or redirect. This step represents business intent and security requirements and must be manually planned and configured.

Once these definitions are complete,iMaster NCE-Campus takes over the execution phase. It automaticallydelivers the policy control matrixto authentication points and policy enforcement points, translating high-level policies into device-level configurations. This ensures consistent policy enforcement across the entire campus network.

In addition, iMaster NCE-Campus automaticallydelivers IP-group entries, which bind user IP addresses to security groups. These entries are dynamically generated based on authentication results and are distributed to relevant devices so that traffic can be correctly identified and controlled as users move.

This division of labor aligns with HCIP Datacom Campus Network design principles, enabling simplified administration, reduced manual configuration, and truly seamless free mobility across the campus network.

In Huawei campus network solutions,free mobilityis a user-centric access control mechanism designed to decouple network policies from physical locations and traditional network identifiers. According to HCIP Datacom Campus Network documentation, free mobility doesnotrely on VLAN IDs or IP addresses as the basis for policy management and permission control. Instead, it is implemented based onuser identity, such as user accounts, roles, user groups, or device identities.

Traditional networks often bind security policies to VLANs or IP subnets, which means users receive different permissions when they move to different access points or switch ports. This approach lacks flexibility and increases configuration complexity. Free mobility solves this problem by using centralized authentication and authorization mechanisms, such as 802.1X or MAC authentication combined with AAA, to dynamically assign policies after user authentication.

Once a user is authenticated, the network enforces access permissions based on predefined user roles or groups, regardless of where the user connects to the network. Even if the user’s IP address or VLAN changes due to roaming, the same security policy is consistently applied. This ensures seamless access experience, simplifies network management, and enhances security control.

Because free mobility isidentity-based rather than VLAN- or IP-based, the statement claiming that it implements policy management and permission control based on users' VLAN IDs and IP addresses is incorrect. Therefore, the correct answer isFALSE.

Super VLAN is a Huawei campus network technology designed to solve broadcast domain and user isolation issues in large Layer 2 networks. It allows multiplesub-VLANsto be associated with a singleSuper VLAN, where the Super VLAN provides Layer 3 gateway services, and sub-VLANs remain Layer 2 isolated from each other. Users within different sub-VLANs cannot communicate directly at Layer 2, which effectively isolates users even though they share the same logical gateway.

This architecture significantly enhances user communication security by preventing direct Layer 2 attacks such as ARP spoofing or broadcast storms between users. In addition, broadcast packets generated within one sub-VLAN are confined to that sub-VLAN and do not propagate to others, preventing invalid or excessive broadcast traffic from impacting overall service quality.

Port isolation only isolates ports but does not provide centralized Layer 3 gateway management. IPSG focuses on IP address legitimacy enforcement rather than user isolation. Ethernet port security restricts MAC address access but does not control broadcast propagation or inter-user isolation across VLANs.

According to HCIP Datacom Campus Network design guidelines, Super VLAN is the correct technology for isolating users in the same VLAN scope while reducing broadcast impact and improving security, making option A correct.

In a CloudCampus VXLAN fabric,node role planningis a fundamental design task that directly affects scalability, performance, and manageability. Huawei defines clear roles for fabric nodes, includingedge nodes,border nodes, and optionallyroute reflectors (RRs).

Statements A, B, and C correctly describe recommended design practices. Core devices are commonly deployed asborder nodesbecause they have higher performance and are well suited to connect the VXLAN fabric to external networks such as WANs or data centers. Access or aggregation devices acting asedge nodesenable end-to-end VXLAN automation and allow user traffic to be encapsulated and decapsulated close to the access layer. Additionally, when external networks exist in different physical locations, deployingmultiple border nodesimproves reliability and optimizes traffic paths.

Statement D is incorrect. In a VXLAN network usingBGP EVPN with route reflectors,edge nodes do not need to establish BGP peer relationships with each other. Instead, edge nodes establish BGP EVPN peer relationshipsonly with the RR, which centrally reflects EVPN routes to other nodes. This design significantly reduces the number of BGP sessions and improves scalability in large networks. Border nodes may also peer with the RR, but full-mesh peering between edge nodes is not required.

Therefore, the false statement isD, making it the correct answer.

In iMaster NCE-Campus, device management functions are tightly integrated with secure remote access mechanisms to ensure safe and efficient O&M operations. One such mechanism is theSSH proxy tunnel, which allows administrators to remotely access managed devices through the controller without directly exposing device management interfaces to the external network.

According to HCIP Datacom Campus Network documentation, theSSH proxy tunnel is automatically established when the Command Line function is usedon the Device Management page. When an administrator clicks theCommand Lineoption, iMaster NCE-Campus dynamically builds a secure SSH proxy channel between the controller and the target device. This enables real-time CLI access to the device through the web interface while maintaining strict security controls.

Other functions such asSummary,Entry Query, andDevice Configurationdo not require direct CLI interaction with the device. These functions rely on management protocols and configuration delivery mechanisms such as NETCONF or telemetry, and therefore do not trigger the establishment of an SSH proxy tunnel.

The Command Line function is specifically designed for scenarios such as advanced troubleshooting, manual verification, or executing device-level commands. Automatically enabling the SSH proxy tunnel at this moment ensures that CLI access is bothsecure and on-demand, reducing attack surfaces and simplifying remote maintenance.

Therefore, the function that automatically enables the SSH proxy tunnel isCommand Line, making optionDthe correct answer.

In campus network design, theegressis a critical point that connects the internal campus network to external networks such as the Internet or WAN. According to HCIP Datacom Campus Network architecture guidelines, ensuringhigh reliability at the egressis essential, even for small- and medium-sized campus networks, because external connectivity directly affects business continuity.

Deployingmulti-carrier linksat the egress is a recommended design practice to enhance reliability. Multi-carrier links refer to connecting the campus network todifferent service providersor independent external links. If one carrier experiences a failure, congestion, or maintenance issue, traffic can be switched to the backup carrier, ensuring uninterrupted external access. This approach significantly reduces the risk of service disruption caused by single-link or single-carrier failures.

For small- and medium-sized campuses, full redundancy with complex architectures may not be cost-effective. Multi-carrier backup links provide acost-efficient and practical solutionthat balances reliability and investment. Technologies such as static route backup, dynamic routing protocols, or policy-based routing can be used to implement automatic failover at the egress.

HCIP Datacom documentation emphasizes that egress reliability is not only a concern for large networks. Even smaller campuses require stable Internet and WAN access for cloud services, remote access, and centralized management platforms. Therefore, deploying multi-carrier links as backup at the egress is a valid and recommended design strategy.

Hence, the statement isTRUE.

IKEv1 negotiation consists of two phases.Phase 1is responsible for establishing a secure IKE Security Association (SA), including peer authentication, key exchange, and protection of subsequent negotiations. In Huawei IPsec implementations, IKEv1 Phase 1 supportsMain modeandAggressive mode.

Main modeuses six message exchanges to securely negotiate parameters, protect identity information, and establish a trusted channel. It provides higher security and is commonly used in site-to-site IPsec VPN scenarios.Aggressive mode, on the other hand, completes negotiation using only three message exchanges, offering faster setup at the cost of reduced identity protection.

Quick modeis not part of IKEv1 Phase 1; it is used inPhase 2to negotiate IPsec SAs for data traffic protection.Normal modeis not a valid IKEv1 negotiation mode.

According to HCIP Datacom Campus Network documentation and standard IPsec principles, the supported IKEv1 Phase 1 negotiation modes areMain mode and Aggressive mode, makingoptions B and Ccorrect.

In campus networks, devices such as servers, print servers, and video surveillance systems requirestable and predictable IP addressesto ensure reliable access, simplified maintenance, and consistent policy enforcement. While fully dynamic DHCP allocation is easy to deploy, it does not guarantee IP address consistency, which complicates device management, monitoring, and troubleshooting.

Huawei campus network design best practices recommendstatic address allocation through DHCP based on MAC addresses, also known as DHCP reservation or static binding. With this approach, the DHCP server assigns a fixed IP address to a device according to its MAC address. This method combines the advantages of centralized DHCP management with the stability of static IP addresses.

PPPoE address binding is typically used in broadband access scenarios and is unsuitable for enterprise campus devices. The BOOT protocol is obsolete and not used in modern campus networks. Pure dynamic DHCP allocation does not meet the stability requirements of infrastructure and service devices.

According to HCIP Datacom Campus Network documentation, MAC-based DHCP static allocation is the recommended solution for managing critical campus devices, making option D correct.

Policy association is a core concept in Huawei campus network security design and is used to associate users, devices, and control elements for unified policy enforcement. According to HCIP Datacom Campus Network documentation, policy association definesthree fixed roles:Terminal,Access device, andControl device.

TheTerminalrepresents the end user or user device accessing the network. TheAccess deviceis typically a switch or wireless access device that provides network access and enforces authentication and authorization policies. TheControl device, such as an authentication or policy control node, is responsible for policy decision-making and centralized management.

APortal serveris not a role within policy association. Instead, it is aservice componentthat provides web-based authentication pages and user interaction during Portal authentication. While it participates in the overall authentication process, it does not belong to the policy association role model.

Therefore, among the given options,Portal serveris not one of the three defined policy association roles. This makesoption Bthe correct answer.
