Which of the following statements about the NSP Workflow Manager (WFM) application is FALSE?

  1. It allows network management tasks to be automated.
  2. Only one workflow can be executed at one time.
  3. Actions and expressions are extensible using Python.
  4. A workflow action can run against RESTCONF APIs.

Answer(s): B

Explanation:

The NSP Workflow Manager (WFM) application allows network management tasks to be automated by creating workflows. Multiple workflows can be run in parallel, and actions and expressions are extensible using Python. Additionally, a workflow action can run against RESTCONF APIs. According to the NSP Release 19.11 Workflow Manager Application Help1, Workflow Manager (WFM) is an application that allows network management tasks to be automated using Nokia NSP or third-party APIs1. WFM supports a variety of use cases such as node software upgrades, service activation tests, service fulfillment and mass migration of services12. WFM uses actions and expressions that are extensible using Python1. A workflow action can run against RESTCONF APIs as well as other protocols such as SNMP, NETCONF and CLI1.



Match the following description with its meaning.
X - "uses Playbooks, written in simple YAML, that defines server configuration." Y - "workflow service that aims to provide a way to define, manage, and execute tasks and workflows in the cloud without writing code.''
Z - "a detailed specification for the desired network configuration.'' W - "an application that allows the creation of complex operational workflows using an intuitive GUI.''

Which of the following is NOT part of the Augmented Assurance features provided by the NSP?

  1. Sorting NEs by highest severity issues
  2. Intelligent visualization
  3. Commissioning of equipment
  4. On-demand OAM testing

Answer(s): C

Explanation:

Augmented Assurance is a feature that provides "extended automated network operations" with

"open APIs and no-code customizable workflows". Another source2 mentions that NSP offers "automated repetitive tasks and complex workflows" to reduce operating costs. The Augmented Assurance features provided by the NSP (Nokia Network Services Platform) include:
A. Sorting NEs by highest severity issues B. Intelligent visualization D. On-demand OAM testing



Which of the following statements about Model-Driven Mediation (MDM) is FALSE?

  1. It CANNOTcommunicatesthrough devices that only support CLI.
  2. It is the foundation for supporting multi-vendor device management.
  3. It provides the translation between the AMI and device model.
  4. It can interface with devices that support OpenConfig gRPC Network Management Interface.

Answer(s): A

Explanation:

Model-Driven Mediation (MDM) is a component that provides mediation between model-driven NSP applications and Nokia or third-party network devices. It uses adaptors to convert NSP application requests to device specific directives using standard protocols such as NETCONF, SNMP and CLI over SSH or Telnet.

This statement is false because MDM can communicate with devices that only support CLI (Command Line Interface) using a translation module that converts CLI commands to NETCONF or RESTCONF protocols. MDM acts as a mediator between the northbound system and the southbound devices by translating device configuration to a standard format that can be consumed by the northbound system.
The other statements are true:
B. It is the foundation for supporting multi-vendor device management. C. It provides the translation between the AMI and device model. D. It can interface with devices that support OpenConfig gRPC Network Management Interface.
