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

location services are part of the NSP REST API, which provides a full list of NSP REST API service names, endpoints and URLs. Therefore, correct answer is A. REST Reference: https://www.nokia.com/networks/training/nsp/self-paced/programmable-network-automation/ https://documentation.nokia.com/cgi-bin/dbaccessfilename.cgi/3HE12075AAACTQZZA01_V1_NSP%2017.6%20API%20Programmer%20Guide.pdf

Intent is a high-level description of the desired outcome or state of the network. It allows users to specify what they want to achieve rather than how to achieve it. The intent is then translated into network configurations and policies that are used to configure the network infrastructure. Intent-based networking provides a higher level of abstraction than traditional network configuration methods, making it easier for users to specify their requirements and automate the configuration process.

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.

An integrated control plane and data plane is NOT an advantage of Software-Defined Networks (SDN) over traditional networks. SDN separates the control plane from the data plane, enabling more efficient and flexible network management. By centralizing the network logic at the controller level, applications can communicate directly with the controller, allowing for greater agility in automating, monitoring, and provisioning network infrastructure.

some of the advantages of Software-Defined Networks (SDN) over traditional networks are:

• Traffic programmability
• Agility
• Policy-driven network supervision
• Network automation
• Centralized controller operations
• Decoupling of control plane from data plane
• Global view of network’s state

According to the Workflow Manager User Guide from Nokia, the correct answer is C. Published. When a workflow is in the Published state, it can be executed by users who have the appropriate permissions. The Draft state is used during the creation of a new workflow, while the Deprecated state indicates that a workflow is no longer supported and should not be used. The Released state is not mentioned in the context of workflow execution.

Kafka is a distributed messaging system that is open-source and can be used to send real-time notifications. However, it has more than four components, such as brokers, partitions, replicas, consumer groups and zookeeper. 

According to the Nokia NSP Workflow Manager Application Help2, Workflow Manager has the following characteristics:

• It provides several building tools to design and create new workflows. You can use graphical editors, text editors, or import existing workflows from files or repositories.
• It uses Openstack Mistral as the core workflow engine. Mistral is an open source project that provides a service for managing workflows across multiple cloud platforms.
• It supports scheduling of workflow executions. You can use cron expressions or triggers to specify when and how often a workflow should run.
• It supports parallel execution of many workflows. You can run multiple workflows simultaneously on different network elements or services.

Therefore, based on these sources, the correct answer is:

B. It uses Openstack Heat as the core workflow engine.

This is FALSE because Workflow Manager uses Openstack Mistral, not Heat, as the core workflow engine. Heat is another open source project that provides a service for orchestrating multiple cloud applications using templates.

The other statements are TRUE because:

• A. It provides several building tools to design and create new workflows. This allows you to create workflows that suit your specific network needs and preferences.
• C. It supports scheduling of workflow executions. This allows you to automate recurring network tasks and optimize network performance and availability.
• D. It supports parallel execution of many workflows. This allows you to handle complex network scenarios and operations efficiently and effectively.

According to the NSP Intent Manager Application Help12, if you select “Modify” under “Behavior” in the WebUI and successfully modify an intent, the intent is updated in the Intent Manager database and compared with the configuration on the target node. This will change the intended configuration for the audit and synchronize operations

The template-mappings can only be viewed by making a RESTCONF call to query an existing intent.

The template-mappings are a set of key-value pairs that map the abstract YANG model attributes to concrete NFM-P templates and parameters. They are not exposed in the UI or the ibn:intent model, but they are stored internally in the NSP database.

For example, a template-mapping could be: /network=IP/service=VPN -> nsp-ip-vpn-template.

According to the Mistral Workflow Language (v2) website1, a workflow definition consists of several attributes that define its properties and behavior. The common workflow attributes are: name, description, type, input, output and vars1.
