This system action allows you to pause a workflow and prompt the user for input. You can use this action to confirm or deny a course of action, or to enter some data that isrequired for the workflow1. For example, you can use nsp.user_input to ask the user if they want to continue with a service deployment or rollback.

The other options are not correct because:

• std.sleep is a standard Python function that pauses the execution of a script for a specified number of seconds2.
• nsp.wait is a system action that waits for an event or condition to occur before resuming the workflow1. For example, you can use nsp.wait to wait for a service activation status change or a network element alarm.
• nsp.pause_before is not a valid system action. There is no such action defined in the NSP documentation1.

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.netconf is a nodal communication action that uses NETCONF protocol to communicate with network devices. The host input represents the management IP address of the device that is being configured by NSP. It is one of the inputs required for nsp.netconf along with username, password, port and command.

The Nokia NSP is an IP network automation platform that provides a unified view of the network and enables end-to-end automation of IP networks. It is designed to be vendor-agnostic and can manage a wide range of equipment from various vendors, making it the Source of Truth for the entire network. It uses NETCONF and YANG to provision the network and can act as a Path Computation Element (PCE).

Nokia NSP is a network automation platform that supports multi-vendor network infrastructure. It acts as the "Source of Truth" for the network, uses NETCONF and YANG to provision the network, and can act as a Path Computation Element (PCE) to optimize traffic flow across the network. It supports a wide range of network devices, including those from third-party vendors, making it a flexible and vendor-agnostic solution for network automation.

some of the statements about the Nokia NSP are:

• It is a platform that provides service automation and network optimization across multiple network layers and domains.
• It uses NETCONF and YANG to provision the network and supports various protocols such as BGP-LS, PCEP, SNMP, etc.
• It can act as a Path Computation Element (PCE) and provide end-to-end path computation for traffic engineering applications.
• It can manage equipment from multiple vendors and supports open interfaces and standards.

According to the NSP Network Services Platform Release 20.9 User Guide1, the attribute of the target-component that determines the component name displayed in the UI is i18n-text.

The i18n-text attribute specifies a key for a localized text string that is displayed as a label for this component in the UI. The actual text string is retrieved from a resource bundle file based on the user’s locale.

For example, if i18n-text is “Port Id”, then the UI will display “Port Id” as the component name.

 the NSP REST Gateway API provides the entry point for API clients to locate and authenticate REST client requests to gain access to the various NSP modules that have registered API services. 

Workflow Manager is a module of Nokia NSP that allows users to create and execute automated procedures and closed loop automation using Nokia NSP or third party APIs3. It uses Mistral as the workflow engine and supports various technologies that can be used in a workflow2.

Some of the technologies that are supported by Workflow Manager out of the box are:

• REST/RESTCONF APIs
• CLI command execution on SROS and third party routers
• Optical integration using TL1
• SNMP traps
• Email notifications

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.

Good coding principles aim to make the code more maintainable and easier to debug. Offloading code and using logging to debug code are both good coding principles, as they make the code more efficient and easier to debug. Adding notes and comments into code is also a good coding practice, as it makes the code more readable and understandable. However, using hard coded values is not a good coding practice, as it makes the code more difficult to maintain and debug.

According to the NSP Intent Manager Application Help, an intent type has to be in Released state for Intent Manager to provision a request. An intent type can be in Draft, Released or Phased-out state. A Draft state means that the intent type is under development and cannot be used for provisioning. A Phased-out state means that the intent type is no longer supported and cannot be used for provisioning
