NEW QUESTION # 53
Which of the following configures the network based on input provided by the user?
- A. Framework files
- B. YANG module
- C. Intent
- D. Intent Type
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 # 54
Which of the following best describes intent-based networking?
- A. Dynamically changing the network infrastructure in real-time through one centralized location
- B. Manual process of configuring networks and reacting to network Issues
- C. Automatic discovery of cross domain links between IP and optical networks
- D. Comparing the actual and desired state of a network and taking action if they are not in sync
Answer: D
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 # 55
Which of the following is NOT an advantage of Software-defined Networks (SDN) over traditional networks?
- A. Decoupling of control plane from data plane
- B. Global view of network's state
- C. Centralized controller operations
- D. Network elements operating autonomously
Answer: D
Explanation:
Explanation
SDN does not provide any advantage in terms of having network elements operate autonomously. The other three options are all advantages of SDN over traditional networks.
Network elements operating autonomously is NOT an advantage of Software-defined Networks (SDN) over traditional networks. SDN aims to centralize control plane operations and provide a global view of the network's state, enabling more efficient and flexible network management. By decoupling the control plane from the data plane, SDN separates the management logic from the forwarding hardware, allowing for centralized and programmable network control.
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

- B. action-based networking -> static networking -> adaptive networking -> autonomous networking
- C. static networking -> action-based networking -> autonomous networking -> adaptive networking
- D. action-based networking -> static networking -> autonomous networking -> adaptive 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.
