QUESTION 41
Which of the following best describes intent-based networking?

Manual process of configuring networks and reacting to network Issues

Dynamically changing the network infrastructure in real-time through one centralized location

Comparing the actual and desired state of a network and taking action if they are not in sync

Automatic discovery of cross domain links between IP and optical networks

Explanation
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.

Provides flexible capabilities for achieving high-level bus

Allows programmable and flexible logic.

Provides concepts for finding misalignments.

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.

It provides information about the root cause(s) of the fault and the affected network elements, as well as enabling automated fault handling and resolution.

QUESTION 51
Which of the following is NOT an advantage of Software-Defined Networks (SDN) over traditional networks?

Network logic is centrally integrated at the controller level

Applications communicate directly with the controller

An integrated control plane and data plane

Greater agility in automating, monitoring, and provisioning network infrastructure

Explanation
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:
