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

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.

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.

Apache FreeMarker is a templating language used to create dynamic webpages. It is designed to separate the configuration and data states, allowing the template to have a consistent look and feel across all webpages. FreeMarker allows the template to instantiate the data, allowing the template to be reused in different contexts. It does not allow communication between NSP applications or transport YANG data.

According to the Workflow Manager User Guide from Nokia, the correct answer is C. Published. When a workflow is in the Published state, it can be executed by users who have the appropriate permissions. The Draft state is used during the creation of a new workflow, while the Deprecated state indicates that a workflow is no longer supported and should not be used. The Released state is not mentioned in the context of workflow execution.

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.

some of the benefits of virtualization are:

• Reduced capital and operating costs
• Better scalability
• Vendor agnostic
• Higher availability and resiliency
• Environmentally friendly

Virtualization enables decoupling of the software and hardware components, so that software can be deployed on any hardware platform without requiring the hardware to be specifically designed for the software. The other three options are all benefits of virtualization.

Software and hardware are tightly coupled is NOT a benefit of virtualization. Virtualization allows software to run independently of the hardware, enabling greater flexibility and scalability. This leads to reduced capital and operating costs, as well as vendor agnostic solutions.

YANG is a data modeling language used to model configuration and state data for network devices. It defines a tree-like structure for data and is used to store, configure, and retrieve information from network devices. It is human readable and can be used to define actions and operations.

Kafka is a distributed messaging system that is open-source and can be used to send real-time notifications. However, it has more than four components, such as brokers, partitions, replicas, consumer groups and zookeeper.
