According to the Nokia NSP Learning and Certification Program2, there are four main NSP applications:

Service Fulfillment: Enables service providers to design, create, and deliver IP/MPLS services across a multi-vendor network.

Network Supervision: Provides real-time visibility and control of network performance, faults, and inventory across physical and virtual networks.

IP/MPLS Optimization: Optimizes network resources by applying advanced algorithms and machine learning techniques to automate traffic engineering and path computation.

Network Virtualization: Enables service providers to create and manage virtualized network functions (VNFs) and network slices using cloud-native technologies.

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.

According to the Nokia NSP Intent Manager Application Help2, an intent has the following characteristics:

It is stored in the database as the source of truth.

It is an instance of an intent type, which defines the structure and logic of an intent.

It can be created and deleted through RESTCONF API or through the Intent Manager GUI.

It can involve services, nodes, links, paths, or any other network elements.

According to the Nokia NSP Intent Manager Application Help2, Intent Manager has the following benefits:

It allows programmable and flexible logic. You can use scripts to define how intents are translated into network commands and how they react to network events.

It provides concepts for finding misalignments. You can use audit and synchronize functions to detect and resolve any discrepancies between intents and network states.

It provides flexible capabilities for achieving high-level business goals. You can use intents to express complex network behaviors such as service protection, bandwidth optimization, or latency reduction.

Therefore, based on these sources12, the correct answer to your question is:

A. Allows the parallel execution of many workflows.

This is NOT a benefit of Intent Manager because workflows are not related to intents. Workflows are sequences of tasks that can be executed on NSP using Workflow Manager.

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.

The NSP Kafka service is a distributed messaging system that allows different applications to publish and subscribe to different event types. It provides an API client to receive event or alarm notifications and subscribe to different event types. However, it does not use NETCONF based operations and YANG models. Instead, it uses the Kafka protocol to send and receive messages between producers and consumers.

Service Fulfilment API does not provide alarm monitoring; rather, it allows customers to quickly and easily order and provision services from a single interface, allowing for increased service agility and reduced human error.

According to the Nokia NSP Service Fulfilment API User Guide, Service Fulfilment API offers the following benefits:

A. Increases service agility by providing a programmable interface for automated service provisioning and management, allowing network operators to quickly respond to customer demands and network changes.

B. Reduces human errors by automating the service provisioning process, which minimizes the risk of manual configuration errors and improves service quality.

C. Allows multi-vendor service provisioning by providing a vendor-agnostic interface that supports different types of network equipment and technologies, reducing vendor lock-in and enabling greater network flexibility.

The correct answer is B. Fault Management API. The Fault Management API can be used to identify the root cause(s) of issues in the network, such as hardware or software faults, configuration errors, and other problems. It provides a unified interface to receive and analyze fault information from multiple network elements.

The API that can identify the root cause(s) of issues in the network is the Fault Management API. This API allows network operators to monitor network faults and events in real-time, and diagnose and resolve issues quickly and efficiently. It provides information about the root cause(s) of the fault and the affected network elements, as well as enabling automated fault handling and resolution.
