- B. Provides concepts for finding misalignments.
- C. Provides flexible capabilities for achieving high-level bus
- D. Allows programmable and flexible logic.
Answer: A
Explanation:
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.

Which of the following statements about Model-Driven Mediation (MDM) is FALSE?
- A. It can interface with devices that support OpenConfig gRPC Network Management Interface.
- B. It provides the translation between the AMI and device model.
- C. It is the foundation for supporting multi-vendor device management.
- D. It CANNOTcommunicatesthrough devices that only support CLI.
Answer: D
Explanation:
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 as NETCONF, 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:
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.
NEW QUESTION # 56
Which of the following sequences best describes the process of moving to SDN based self-regulated networking?
- A. static networking -> action-based networking -> adaptive networking > autonomous networking
- B. static networking -> action-based networking -> autonomous networking -> adaptive networking
- C. action-based networking -> static networking -> autonomous networking -> adaptive networking
- D. action-based networking -> static networking -> adaptive networking -> autonomous networking
Answer: A
Explanation:
Explanation
Nokia NSP is a platform that enables management, control and automation of IP/Optical networks. It supports various levels of network automation, from static networking to autonomous networking.
The process of moving to SDN based self-regulated networking involves four stages:
* Static networking: The network is manually configured and operated by human operators. There is no automation or intelligence involved.
* Action-based networking: The network is partially automated by using predefined actions or scripts that are triggered by events or commands. There is still human intervention required for complex tasks or exceptions.
* Adaptive networking: The network is dynamically automated by using policies, analytics and machine learning that can adjust the network behavior based on changing conditions and objectives. There is minimal human intervention required for oversight and validation.
* Autonomous networking: The network is fully automated by using artificial intelligence and closed-loop feedback that can optimize the network performance and reliability without any human involvement.
The network can self-heal, self-optimize and self-protect.

NEW QUESTION # 60
Which of the following configures the network based on input provided by the user?
- A. Intent Type
- B. Framework files
- C. YANG module
- D. Intent
Answer: D
Explanation:
Explanation
Intent is a high-level description of the desired outcome or state of the network. It allows users to specify what they want to achieve rather than how to achieve it. The intent is then translated into network configurations and policies that are used to configure the network infrastructure. Intent-based networking provides a higher level of abstraction than traditional network configuration methods, making it easier for users to specify their requirements and automate the configuration process.
