Nokia 4A0-AI1 Nokia NSP IP Network Automation Professional Exam Practice Test

The Framework file contains helper functions that can be leveraged by the scripts of many different Intent types.

The Framework file is a JavaScript file that provides common utility functions for Intent operations. It is located in the /opt/nokia/nsp/intent/scripts directory on the NSP server. It can be imported by other script files using the require() function.

For example, a Framework file could contain:

function getNfmpTemplate(templateName) { // logic for getting an NFM-P template by name }

function getMdTemplate(templateName) { // logic for getting an MD template by name }

This syntax assumes that there is a previous task that returns an object with an attribute named rtt that contains the round-trip time value1. The expression <% task().result.rtt %> evaluates to this value and assigns it to the variable rtt in the workflow context1.

CLI is not used in Model Driven Telemetry. Model Driven Telemetry is a technology that uses YANG data models, NETCONF, gRPC and KAFKA to monitor and collect data from network elements. It provides an abstracted view of the network element and is vendor agnostic.

Model Driven Telemetry is a method of collecting real-time data from network devices, allowing for more efficient network monitoring and troubleshooting. It uses a variety of protocols and standards, including NETCONF, gRPC, and Kafka. However, CLI is a text-based user interface used for issuing commands to a device, and it is not typically used for collecting telemetry data.

According to the Nokia Network Services Platform for industry and the public sector datasheet1, NSP model-driven telemetry framework supports the Nokia SR OS and third-party devices in configuring and collecting performance statistics using gRPC, SNMP, NETCONF and accounting files such as SAP QoS1. It also enables data to be persisted in a database and be made available (e.g., over a Kafka bus) for a variety of use cases1.

An Intent is the master configuration that is synchronized with the network configuration and is stored in the database as the source of truth. Intent Types define the type of Intent, such as a network service or a configuration change, while Metadata is used to store additional information about the Intent, such as its version or author. YANG modules are used to define the data model for a particular technology.

According to the NSP Intent Manager Application Help, an intent type has to be in Released state for Intent Manager to provision a request. An intent type can be in Draft, Released or Phased-out state. A Draft state means that the intent type is under development and cannot be used for provisioning. A Phased-out state means that the intent type is no longer supported and cannot be used for provisioning

Nokia NSP is a platform that enables management, control and automation of IP/Optical networks. It supports various levels of network automation, from static networking to autonomous networking.

The process of moving to SDN based self-regulated networking involves four stages:

• Static networking: The network is manually configured and operated by human operators. There is no automation or intelligence involved.
• Action-based networking: The network is partially automated by using predefined actions or scripts that are triggered by events or commands. There is still human intervention required for complex tasks or exceptions.
• Adaptive networking: The network is dynamically automated by using policies, analytics and machine learning that can adjust the network behavior based on changing conditions and objectives. There is minimal human intervention required for oversight and validation.
• Autonomous networking: The network is fully automated by using artificial intelligence and closed-loop feedback that can optimize the network performance and reliability without any human involvement. The network can self-heal, self-optimize and self-protect.

Good coding principles aim to make the code more maintainable and easier to debug. Offloading code and using logging to debug code are both good coding principles, as they make the code more efficient and easier to debug. Adding notes and comments into code is also a good coding practice, as it makes the code more readable and understandable. However, using hard coded values is not a good coding practice, as it makes the code more difficult to maintain and debug.

some of the operations that can be performed on an Intent are:

• Create
• Synchronize
• Audit
• Update
• Delete

Therefore, based on this source, the answer that CANNOT be performed on an Intent is C. Phase-out.

 the NSP REST Gateway API provides the entry point for API clients to locate and authenticate REST client requests to gain access to the various NSP modules that have registered API services. 

nsp.netconf is a nodal communication action that uses NETCONF protocol to communicate with network devices. The host input represents the management IP address of the device that is being configured by NSP. It is one of the inputs required for nsp.netconf along with username, password, port and command.

Infrastructure Lure Intents are a type of Network Intent that describe how network resources should be allocated and configured for a specific service or application.

L2/L3 VPN configuration of multiple services is NOT a characteristic of Infrastructure Lure Intents, because it is more related to service provisioning than resource allocation.
