a Kafka topic is a channel where publishers (producers) publish data and where subscribers (consumers) receive data. A topic represents a stream of messages of a particular category. 

In Kafka, a topic represents a stream of messages of a particular category or type. Producers publish messages to a specific topic, and consumers subscribe to and read messages from topics. Brokers are responsible for managing topics and ensuring that messages are distributed efficiently across the cluster.

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.

Augmented Assurance is a feature that provides “extended automated network operations” with “open APIs and no-code customizable workflows”. Another source2 mentions that NSP offers “automated repetitive tasks and complex workflows” to reduce operating costs.

The Augmented Assurance features provided by the NSP (Nokia Network Services Platform) include:

A. Sorting NEs by highest severity issues B. Intelligent visualization D. On-demand OAM testing

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 Help1, Workflow Manager (WFM) is an application that allows network management tasks to be automated using Nokia NSP or third-party APIs1. WFM supports a variety of use cases such as node software upgrades, service activation tests, service fulfillment and mass migration of services12. WFM uses actions and expressions that are extensible using Python1. A workflow action can run against RESTCONF APIs as well as other protocols such as SNMP, NETCONF and CLI1.

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 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.

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.

a system token is a string that is used to authenticate requests to the NSP REST API. A system token can be obtained by sending a POST request to the /token endpoint with a valid username and password1. a system token is valid for 60 minutes before expiring. After expiration, a new system token must be obtained by repeating the authentication process2.

YANG modules do not require proprietary MIBS. YANG modules are used to define the structure and content of a network configuration and are written in a structured language that consists of containers and leaves. YANG modules are used in conjunction with NETCONF and RESTCONF to transport data, and they provide a separation of configuration and state data.
