Virtualization is not a characteristic of intent-based networking, but rather a technology that enables it. Virtualization is the process of creating virtual versions of physical resources, such as servers, storage, or networks1. Virtualization allows for more flexibility and scalability in network design and management, but does not imply any automation or intelligence.

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:

B. 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:

• A. 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.
• C. It supports scheduling of workflow executions. This allows you to automate recurring network tasks and optimize network performance and availability.
• D. It supports parallel execution of many workflows. This allows you to handle complex network scenarios and operations efficiently and effectively.

a workflow can use environments to make it portable if the workflow needs to be executed on either a development or production lab. Environments are files that contain key-value pairs that can be used as input parameters for workflows1. Environments allow workflows to be executed with different settings without modifying the workflow definition1.

According to the Nokia NSP Programmable Network Automation website1, NSP API documentation and downloadable sample codes are available on the Nokia Network Developer Portal. The NSP Workflow Manager allows the design and management of workflows to automate network operations using Mistral DSL v2 which is based on YAML2. YAML definesexpressions in workflow and action definitions. The formatting of the YAML must comply with Mistral DSL v2 specifications3
