NEW QUESTION # 32
Which of the following configures the network based on input provided by the user?
- A. Intent Type
- B. YANG module
- C. Intent
- D. Framework files
Answer: C
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.
NEW QUESTION # 33
Which of the following best describes intent-based networking?
- A. Manual process of configuring networks and reacting to network Issues
- B. Comparing the actual and desired state of a network and taking action if they are not in sync
- C. Automatic discovery of cross domain links between IP and optical networks
- D. Dynamically changing the network infrastructure in real-time through one centralized location
Answer: B
Explanation:
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.
NEW QUESTION # 34
Which of the following statements about NSP APIs is FALSE?
- A. They help with the definition and activation of network services.
- B. They allow for supervision of network elements.
They support REST/RESTCONF, SOAP/XML and GraphQlll1 - C. They allow for an OSS and NSP server to talk to each other.
Answer: A
Explanation:
Explanation
NSP APIs allow for supervision of network elements, help with the definition and activation of network services, and allow for an OSS and NSP server to talk to each other. However, they do not support GraphQL, which is a query language for APIs.
According to Nokia NSP IP Network Automation Professional guide, NSP APIs support REST/RESTCONF, SOAP/XML and GraphQlll, and help with the definition and activation of network services, and they also allow for supervision of network elements and an OSS and NSP server to talk to each other. Therefore, statement B is false as it states that NSP APIs support Kafka which is not mentioned in the guide as a supported API.
