4A0-AI1 Nokia NSP IP Network Automation Professional Composite Exam Questions and Answers

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.

CLI is not used in Model Driven Telemetry. Model Driven Telemetry is a technology that uses YANG data models, NETCONF, gRPC and KAFKA to monitor and collect data from network elements. It provides an abstracted view of the network element and is vendor agnostic.

Model Driven Telemetry is a method of collecting real-time data from network devices, allowing for more efficient network monitoring and troubleshooting. It uses a variety of protocols and standards, including NETCONF, gRPC, and Kafka. However, CLI is a text-based user interface used for issuing commands to a device, and it is not typically used for collecting telemetry data.

According to the Nokia Network Services Platform for industry and the public sector datasheet1, NSP model-driven telemetry framework supports the Nokia SR OS and third-party devices in configuring and collecting performance statistics using gRPC, SNMP, NETCONF and accounting files such as SAP QoS1. It also enables data to be persisted in a database and be made available (e.g., over a Kafka bus) for a variety of use cases1.

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

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 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.

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

REST and RESTCONF APIs provide a single entry point into the consolidated suite of NSP applications. Another source2 mentions that NSP REST gateway provides access to NSD and NRC functionalities through REST API services. A third source3 explains that RESTCONF is an HTTP-based protocol that performs CRUD operations on data using YANG models. 

An Intent is the master configuration that is synchronized with the network configuration and is stored in the database as the source of truth. Intent Types define the type of Intent, such as a network service or a configuration change, while Metadata is used to store additional information about the Intent, such as its version or author. YANG modules are used to define the data model for a particular technology.
