file actions are NSP actions that provide access to files and folders on the NSP server. The file actions can access  all directories  on 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.

This syntax assumes that there is a previous task that returns an object with an attribute named  rtt  that contains the round-trip time value 1 .  The expression  < % task().result.rtt % >  evaluates to this value and assigns it to the variable  rtt  in the workflow context 1 .

some of the benefits of virtualization are:

Reduced capital and operating costs

Better scalability

Vendor agnostic

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.

Intent Manager to communicate with network elements that are not directly supported by NSP 1 2 . A generic mediator can use SNMP or other protocols to interact with network elements.

A Postman account allows you to create a maximum of 3600 workspaces for free. Postman is an API development environment used to create, test, and document APIs. It allows users to send requests and receive responses in a variety of formats, as well as add parameters to requests, define variables to store and re-use values, and execute pre-request scripts before the main request. However, Postman accounts do not allow users to create a maximum of 3600 workspaces for free; users must upgrade their accounts to access this feature.

NSP APIs allow for supervision of network elements, help with the definition and activation of network services, and allow for an OSS and NSP server to talk to each other. However, they do not support GraphQL, which is a query language for APIs. 

According to Nokia NSP IP Network Automation Professional guide, NSP APIs support REST/RESTCONF, SOAP/XML and GraphQlll, and help with the definition and activation of network services, and they also allow for supervision of network elements and an OSS and NSP server to talk to each other. Therefore, statement B is false as it states that NSP APIs support Kafka which is not mentioned in the guide as a supported API.

According to the Mistral Workflow Language (v2) website 1 , Mistral Workflow Language supports  YAQL  and  Jinja2  expression languages to reference workflow context variables and thereby implements passing data between workflow tasks. It’s also referred to as Data Flow mechanism.  YAQL is a simple but powerful query language that allows to extract needed information from JSON structured data 1 .

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 Help 1 ,  Workflow Manager (WFM)  is an application that allows network management tasks to be automated using Nokia NSP or third-party APIs 1 .  WFM supports a variety of use cases such as node software upgrades, service activation tests, service fulfillment and mass migration of services 1 2 .  WFM uses actions and expressions that are extensible using Python 1 .  A workflow action can run against RESTCONF APIs as well as other protocols such as SNMP, NETCONF and CLI 1 .

The value type attributes of the target-component can be assigned either a boolean or a string data type. The boolean data type can be used to indicate whether a certain attribute is enabled or not, while the string data type can be used to store textual information. Numbers and other data types are not supported.
