Question 1

A team of migration cloud architects are evaluating different storage options for deploying virtual machines (VMs) in Oracle Cloud VMware Solution (OCVS). They are comparing VMware vSAN and OCI Block Storage to determine the best fit for their needs. Which two statements accurately reflect the usage of vSAN and OCI Block Storage in OCVS?

Options:

A.

OCI Block Storage inherently provides better IOPS performance than vSAN for all workload types

B.

OCI Block Storage can be scaled up or down independently of compute resources, unlike vSAN which scales with the cluster

C.

vSAN requires an external network connectivity to synchronize data across hosts, whereas OCI Block Storage does not

D.

vSAN is tightly integrated with VMware's SDDC ecosystem, thus allowing for storage policies to be directly applied to VMs, whereas OCI Block Storage operates as independent block volumes

E.

OCI Block Storage can utilize VMware-specific storage policies for VM provisioning and management, just like vSAN in the OCVS environment

Question 2

Exadata Database on Cloud@Customer

D.

Autonomous Database on Cloud@Customer

Conduct comprehensive testing and monitor performance metrics

C.

Gradually shift traffic from the source environment to OKE

D.

Efficiently manage packages with Helm charts

Question 5

Your company is planning to migrate on-premises workloads to Oracle Cloud Infrastructure (OCI). As a migration cloud architect, you are considering Oracle Cloud Migrations service for this initiative. Which two are core features of Oracle Cloud Migrations service?

Provide detailed application topology to choose the target OCI Region

B.

Estimate the cost to run the migrated workloads in the OCI environment

C.

Transfer large volumes of data through a storage appliance

D.

Group and organize discovered workloads to represent applications & lines of business

E.

Automatic containerization of Virtual Machines to Oracle Container Engine for Kubernetes (OKE)

Question 6

Your company wants to expand its cloud infrastructure footprint by adopting Oracle Cloud VMware Solution (OCVS). The OCVS Software Defined Data Center (SDDC) platform will be dedicated to hosting business-critical workloads and should avoid single points of failure within its architecture. Which two would be considered while setting up the solution?

Options:

A.

vSphere Distributed Resource Scheduler (DRS)

B.

OCI Fault Domain

C.

vSAN Fault Domain

D.

HCX Mobility Groups

Question 7

Which statement accurately describes the routing mechanism within a Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI)?

Options:

A.

Each subnet within a VCN employs multiple route rules, allowing for diverse routing paths based on traffic priorities

B.

A subnet in a VCN is associated with a single route table, dictating how outbound traffic from all Virtual Network Interface Cards (VNICs) within that subnet is directed

C.

If no route rule matches the network traffic you intend to route outside the VCN, the traffic is sent to the Internet

D.

VCN local routing necessitates manual configuration of route rules to facilitate infrastructure communication

Question 8

Which three transfer mediums does the OCI Database Migration service use to perform the initial load of the databases?

Options:

A.

Data Pump via File Storage

B.

Data Pump via Object Storage

C.

Data Pump via network link

D.

Data Guard via replication

E.

Data Pump dump upload via OCI CLI

Question 9

You have been tasked with provisioning an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster to deploy new applications and manage existing ones. Which two statements are FALSE?

Options:

A.

To access the cluster using kubectl, you have to set up a Kubernetes manifest file stored in the $HOME/.manifest directory

B.

When a cluster's Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file

C.

The only available option when a cluster's Kubernetes API endpoint has a public IP address is to control the cluster locally using kubectl and the Kubernetes Dashboard

D.

To access the cluster using kubectl, you have to set up a Kubernetes configuration file stored in the $HOME/.kube directory

Question 10

You are a migration architect responsible for managing data storage solutions in Oracle Cloud Infrastructure (OCI). You configured a Storage Gateway file system on a local host running in an on-premises datacenter, which maps to an Object Storage bucket with an identical name in OCI. What happens when a file is written to a Storage Gateway file system?

Options:

A.

The file is stored locally on the host machine

B.

The file is written as an object with the same name in the associated Object Storage bucket

C.

The file is uploaded to OCI Object Storage synchronously

D.

The file is replicated to multiple Object Storage buckets for redundancy

Question 11

Which two represent an Oracle database migration scenario?

Options:

A.

Changing the Oracle database host platform from Windows to Linux

B.

Enabling encryption on your database

C.

Changing the character set of the Oracle database

D.

Upgrading the Oracle database from release 11g to 23c
