Important Nokia 4A0-AI1 Exam Questions

Answer: A

Explanation:

Model-Driven Mediation (MDM) is a component that provides mediation between model-driven NSP applications and Nokia or third-party network devices. It uses adaptors to convert NSP application requests to device specific directives using standard protocols such asNETCONF, SNMP and CLI over SSH or Telnet.

This statement is false because MDM can communicate with devices that only support CLI (Command Line Interface) using a translation module that converts CLI commands to NETCONF or RESTCONF protocols. MDM acts as a mediator between the northbound system and the southbound devices by translating device configuration to a standard format that can be consumed by the northbound system.

The other statements are true:

1. It is the foundation for supporting multi-vendor device management. C. It provides the translation between the AMI and device model. D. It can interface with devices that support OpenConfig gRPC Network Management Interface.

Answer: D

Explanation:

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

Answer: B

Explanation:

orchestrationis the automated configuration, coordination, and management of computer systems and software. Orchestration takes advantage of several tasks that are usually automated to create a more complex workflow.

An orchestrator is a software tool that is used to automate the configuration, coordination, and management of large virtualized systems, middleware, and services. The other three options are not related to the automated configuration, coordination, and management of large virtualized systems, middleware, and services.

Orchestrator is described as 'the automated configuration, coordination, and management of large virtualized systems, middleware, and services.' The orchestrator is a key component of network automation, enabling the automation and management of complex network functions across multiple devices and platforms.

Answer: A

Explanation:

The main sections of an abstract YANG module file areargumentsandstatements.

An argument is a string that provides additional information about a statement. A statement is a keyword followed by an argument and optionally enclosed by braces ({ }) containing substatements.

For example, an abstract YANG module file could start with:

module ibn-intent { namespace ''urn:nokia.com:ibn:intent''; prefix ibn;

This defines the module name, namespace and prefix as arguments for the module, namespace and prefix statements respectively.

Answer: A

Explanation:

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 frameworksupports the Nokia SR OS and third-party devices in configuring and collecting performance statistics usinggRPC, SNMP,NETCONFand accounting files such as SAP QoS1.It also enables data to be persisted in a database and be made available (e.g., over aKafkabus) for a variety of use cases1.
