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.

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.

Intent is a high-level description of the desired outcome or state of the network. It allows users to specify what they want to achieve rather than how to achieve it. The intent is then translated into network configurations and policies that are used to configure the network infrastructure. Intent-based networking provides a higher level of abstraction than traditional network configuration methods, making it easier for users to specify their requirements and automate the configuration process.

The HTTP methods that are supported by REST/RESTCONF are:

OPTIONS: Used to retrieve the communication options available for a resource.

GET: Used to retrieve a representation of a resource.

PATCH: Used to apply a partial update to a resource.

POST: Used to create a new resource or trigger a specific action.

The HTTP method TRACE is not supported by REST/RESTCONF.

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:

1. 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:

2. 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.

3. It supports scheduling of workflow executions.This allows you to automate recurring network tasks and optimize network performance and availability.

4. It supports parallel execution of many workflows.This allows you to handle complex network scenarios and operations efficiently and effectively.

An integrated control plane and data plane is NOT an advantage of Software-Defined Networks (SDN) over traditional networks. SDN separates the control plane from the data plane, enabling more efficient and flexible network management. By centralizing the network logic at the controller level, applications can communicate directly with the controller, allowing for greater agility in automating, monitoring, and provisioning network infrastructure.

some of the advantages of Software-Defined Networks (SDN) over traditional networks are:

Traffic programmability

Agility

Policy-driven network supervision

Network automation

Centralized controller operations

Decoupling of control plane from data plane

Global view of network's state

This syntax assumes that there is a previous task that returns an object with an attribute namedrttthat contains the round-trip time value1.The expression<% task().result.rtt %>evaluates to this value and assigns it to the variablerttin the workflow context1.

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.
