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.

According to the NSP Intent Manager Application Help12, if you select “Modify” under “Behavior” in the WebUI and successfully modify an intent, the intent is updated in the Intent Manager database and compared with the configuration on the target node. This will change the intended configuration for the audit and synchronize operations

location services are part of the NSP REST API, which provides a full list of NSP REST API service names, endpoints and URLs. Therefore, correct answer is A. REST Reference: https://www.nokia.com/networks/training/nsp/self-paced/programmable-network-automation/ https://documentation.nokia.com/cgi-bin/dbaccessfilename.cgi/3HE12075AAACTQZZA01_V1_NSP%2017.6%20API%20Programmer%20Guide.pdf

The template-mappings can only be viewed by making a RESTCONF call to query an existing intent.

The template-mappings are a set of key-value pairs that map the abstract YANG model attributes to concrete NFM-P templates and parameters. They are not exposed in the UI or the ibn:intent model, but they are stored internally in the NSP database.

For example, a template-mapping could be: /network=IP/service=VPN -> nsp-ip-vpn-template.

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.

Comparing the actual and desired state of a network and taking action if they are not in sync. Intent-based networking is a method of managing a network by defining the intent of the network and then continuously comparing the actual and desired state of the network. If the two states are not in sync, the system will take action to bring the actual state in line with the desired one. This is different from manual processes of configuring networks or reacting to network issues. It also differs from dynamically changing the network infrastructure in real-time through one centralized location, or automatic discovery of cross domain links between IP and optical networks.

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.

According to the Mistral Workflow Language (v2) website1, a workflow definition consists of several attributes that define its properties and behavior. The common workflow attributes are: name, description, type, input, output and vars1.

An integrated control plane and data plane is NOT an advantage of Software-Defined Networks (SDN) over traditional networks. SDN separates the control plane from the data plane, enabling more efficient and flexible network management. By centralizing the network logic at the controller level, applications can communicate directly with the controller, allowing for greater agility in automating, monitoring, and provisioning network infrastructure.

some of the advantages of Software-Defined Networks (SDN) over traditional networks are:

Traffic programmability

Agility

Policy-driven network supervision

Network automation

Centralized controller operations

Decoupling of control plane from data plane

Global view of network’s state
