Which of the following statements best describe delegation in a network? Each correct answer represents a complete solution

Which of the following statements best describe delegation in a network? Each correct answer represents a complete solution. Choose two.

A.
It improves security by limiting broadcasts to the local network.

B.
It is an act or profession of splitting a computer network into subnetworks.

C.
Its usability depends on used authentication method and appropriate account configuration.

D.
It allows a user to use an impersonation token to access network resources.

Explanation:
Delegation is the assignment of authority and responsibility to another person to carry out specific activities. It allows a user to use an impersonation token to access network resources.

The ability to use delegation depends on used authentication method and appropriate account configuration. User should be careful while using impersonation and delegation because of the additional security and scalability issues caused by it. There are two types of delegation in a network:
Delegation at Authentication/Identity Level
Delegation at Authorization/Access Control Level

Answer options B and A are incorrect. Network segmentation in computer networking is the act or profession of splitting a computer network into subnetworks, each being a network segment or network layer. The advantages of such splitting are primarily for boosting performance and improving security.
Advantages:
Reduced congestion: improved performance is achieved because on a segmented network, there are fewer hosts per subnetwork, thus minimizing local traffic.

Improved security: Broadcasts will be contained to the local network. Internal network structure will not be visible from outside.

Containing network problems: It limits the effect of local failures on other parts of the network.
