Nokia 4A0-AI1 Exam Questions

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.

The Nokia NSP is an IP network automation platform that provides a unified view of the network and enables end-to-end automation of IP networks. It is designed to be vendor-agnostic and can manage a wide range of equipment from various vendors, making it the Source of Truth for the entire network. It uses NETCONF and YANG to provision the network and can act as a Path Computation Element (PCE).

Nokia NSP is a network automation platform that supports multi-vendor network infrastructure. It acts as the 'Source of Truth' for the network, uses NETCONF and YANG to provision the network, and can act as a Path Computation Element (PCE) to optimize traffic flow across the network. It supports a wide range of network devices, including those from third-party vendors, making it a flexible and vendor-agnostic solution for network automation.

some of the statements about the Nokia NSP are:

It is a platform that provides service automation and network optimization across multiple network layers and domains.

It uses NETCONF and YANG to provision the network and supports various protocols such as BGP-LS, PCEP, SNMP, etc.

It can act as a Path Computation Element (PCE) and provide end-to-end path computation for traffic engineering applications.

It can manage equipment from multiple vendors and supports open interfaces and standards.

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.

The {{...}} syntax is used to reference a workflow variable when using Jinja2. Jinja2 is a templating language used to generate dynamic text based on input variables, and the {{...}} syntax is used to access the value of a workflow variable within a Jinja2 template. The other syntaxes provided are not valid for referencing workflow variables in Jinja2.

According to the Mistral Workflow Language (v2) documentation1, which is one of the technologies that can be used in a NSP workflow2, flow control attributes are used to define how a task behaves depending on its execution status.The valid flow control attributes areon-success,on-error,on-complete, andon-cancel1. Therefore, the correct answer is A.
