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 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.

Explanation
The statement that best describes the Intent Manager application is: “It generates and validates the configuration of the network.” Intent Manager is responsible for collecting the user’s intent, verifying the user’s input, and converting the user’s intent into a device-specific configuration. It uses a high-level language to abstract the network complexity, enabling the network operator to define intent in simple terms. Once the intent is defined, Intent Manager automatically generates a device-specific configuration for each network element. It then validates the intent by checking the network’s current state against the user’s desired intent. If there is a mismatch, it will take corrective action to bring the network to the desired intent state.

Explanation
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.

Explanation
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.

Explanation
Good coding principles aim to make the code more maintainable and easier to debug. Offloading code and using logging to debug code are both good coding principles, as they make the code more efficient and easier to debug. Adding notes and comments into code is also a good coding practice, as it makes the code more readable and understandable. However, using hard coded values is not a good coding practice, as it makes the code more difficult to maintain and debug.

Explanation
This attribute specifies a manual approval step before executing a task1. The other attributes will either delay or abort the execution of a task, but not halt the entire workflow.

Explanation
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 are on-success, on-error, on-complete, and on-cancel1.
Therefore, the correct answer is A.

Explanation
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.

Explanation
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.

Explanation
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.

Explanation
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 sources
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.

Explanation
According to the NSP Intent Manager Application Help, an intent type has to be in Released state for Intent Manager to provision a request. An intent type can be in Draft, Released or Phased-out state. A Draft state means that the intent type is under development and cannot be used for provisioning. A Phased-out state means that the intent type is no longer supported and cannot be used for provisioning

Explanation
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:

Explanation
According to the Nokia NSP Learning and Certification Program2, there are four main NSP applications:
* Service Fulfillment: Enables service providers to design, create, and deliver IP/MPLS services across a multi-vendor network.
* Network Supervision: Provides real-time visibility and control of network performance, faults, and inventory across physical and virtual networks.
* IP/MPLS Optimization: Optimizes network resources by applying advanced algorithms and machine learning techniques to automate traffic engineering and path computation.
* Network Virtualization: Enables service providers to create and manage virtualized network functions (VNFs) and network slices using cloud-native technologies.
