Which of the following is NOT an advantage of Software-defined Networks (SDN) over traditional networks?
- A. Centralized controller operations
- B. Network elements operating autonomously
- C. Decoupling of control plane from data plane
- D. Global view of network's state
Answer: B
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

NEW QUESTION # 34
Which of the following best describes intent-based networking?
- A. Manual process of configuring networks and reacting to network Issues
- B. Dynamically changing the network infrastructure in real-time through one centralized location
- 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 # 35
Which of the following system actions will pause a workflow at some point and wait for an operator to confirm or deny a particular course of action?
- A. nsp.wait
- B. std. sleep
- C. nsp.pause_before
- D. nsp.user_input
Answer: D
Explanation:
Explanation
This system action allows you to pause a workflow and prompt the user for input. You can use this action to confirm or deny a course of action, or to enter some data that isrequired for the workflow1. For example, you can use nsp.user_input to ask the user if they want to continue with a service deployment or rollback.
The other options are not correct because:
* std.sleep is a standard Python function that pauses the execution of a script for a specified number of seconds2.
* nsp.wait is a system action that waits for an event or condition to occur before resuming the workflow1.
For example, you can use nsp.wait to wait for a service activation status change or a network element alarm.
* nsp.pause_before is not a valid system action. There is no such action defined in the NSP documentation

Which of the following can only be viewed by making a RESTCONF call to query an existing intent?
- A. ibn:intent model
- B. template-mappings
- C. metadata
- D. abstract YANG model
Answer: B
Explanation:
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
The main sections of an abstract YANG module file are arguments and statements.
An argument is a string that provides additional information about a statement. A statement is a keyword followed by an argument and optionally enclosed by braces ({ }) containing substatements.
For example, an abstract YANG module file could start with:
module ibn-intent { namespace "urn:nokia.com:ibn:intent"; prefix ibn;
This defines the module name, namespace and prefix as arguments for the module, namespace and prefix statements respectively.
NEW QUESTION # 40
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.
