Which of the following statements about an intent is FALSE?

  1. It is stored in the database as the source of truth.
  2. It is an instance of an intent type.
  3. It can be created and deleted through RESTCONF API.
  4. It only involves services.

Answer(s): D

Explanation:

According to the Nokia NSP Intent Manager Application Help2, an intent has the following characteristics:
It is stored in the database as the source of truth.
It is an instance of an intent type, which defines the structure and logic of an intent. It can be created and deleted through RESTCONF API or through the Intent Manager GUI. It can involve services, nodes, links, paths, or any other network elements.



Which of the following is NOT a benefit of Intent Manager?

  1. Allows the parallel execution of many workflows.
  2. Provides flexible capabilities for achieving high-level bus
  3. Allows programmable and flexible logic.
  4. Provides concepts for finding misalignments.

Answer(s): A

Explanation:

According to the Nokia NSP Intent Manager Application Help2, Intent Manager has the following benefits:
It allows programmable and flexible logic. You can use scripts to define how intents are translated into network commands and how they react to network events. It provides concepts for finding misalignments. You can use audit and synchronize functions to detect and resolve any discrepancies between intents and network states. It provides flexible capabilities for achieving high-level business goals. You can use intents to express complex network behaviors such as service protection, bandwidth optimization, or latency reduction. Therefore, based on these sources12, the correct answer to your question is:
A. Allows the parallel execution of many workflows.
This is NOT a benefit of Intent Manager because workflows are not related to intents. Workflows are sequences of tasks that can be executed on NSP using Workflow Manager.



Which of the following statements about the NSP Workflow Manager is FALSE?

  1. It provides several building tools to design and create new workflows.
  2. It uses Openstack Heat as the core workflow engine.
  3. It supports scheduling of workflow executions.
  4. It supports parallel execution of many workflow.

Answer(s): B

Explanation:

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.



Which of the following statements about the NSP Kafka service is FALSE?

  1. It allows an API client to receive event or alarm notifications.
  2. It allows an API client to subscribe to different event types.
  3. It is a distributed messaging system.
  4. It uses NETCONF based operations and YANG models.

Answer(s): D

Explanation:

The NSP Kafka service is a distributed messaging system that allows different applications to publish and subscribe to different event types. It provides an API client to receive event or alarm notifications and subscribe to different event types. However, it does not use NETCONF based operations and YANG models. Instead, it uses the Kafka protocol to send and receive messages between producers and consumers.
