Nokia NSP IP Network Automation Professional Composite 4A0-AI1 Exam Questions

Answer : B

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.

Answer : C

NSP Workflow Manager (WFM) is a module that allows users to create and execute automated procedures using NSP or third-party APIs. A workflow is a sequence of actions that can be performed on various targets such as:

NSP applications: These are the applications that run on NSP such as Network Insight, Service Assurance, Traffic Engineering and others.They can be accessed by using RESTful APIs2.

Network elements: These are the devices that are managed by NSP such as routers, switches and optical equipment.They can be accessed by using CLI, NETCONF, RESTCONF, SNMP or TL12.

UNIX servers: These are the servers that run UNIX-based operating systems such as Linux or Solaris.They can be accessed by using SSH or SCP2.

Answer : A

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 asNETCONF, 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:

1. 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.

Answer : D

some of the benefits of virtualization are:

Reduced capital and operating costs

Better scalability

Higher availability and resiliency

Environmentally friendly

Virtualization enables decoupling of the software and hardware components, so that software can be deployed on any hardware platform without requiring the hardware to be specifically designed for the software. The other three options are all benefits of virtualization.

Software and hardware are tightly coupled is NOT a benefit of virtualization. Virtualization allows software to run independently of the hardware, enabling greater flexibility and scalability. This leads to reduced capital and operating costs, as well as vendor agnostic solutions.

Answer : C

a system token is a string that is used to authenticate requests to the NSP REST API.A system token can be obtained by sending a POST request to the /token endpoint with a valid username and password1. a system token is valid for60 minutesbefore expiring.After expiration, a new system token must be obtained by repeating the authentication process2.

Answer : B

file actions are NSP actions that provide access to files and folders on the NSP server. The file actions can accessall directorieson the NSP server, but they are restricted by the permissions of the user who runs them. For example, if a file action is run by a user who does not have write permission to a directory, the action will fail.

Answer : A

Apache FreeMarker is a templating language used to create dynamic webpages. It is designed to separate the configuration and data states, allowing the template to have a consistent look and feel across all webpages. FreeMarker allows the template to instantiate the data, allowing the template to be reused in different contexts. It does not allow communication between NSP applications or transport YANG data.
