CAS-002 Question #461: Real Exam Question with Answer & Explanation

Question

Options

• AIt improves security by limiting broadcasts to the local network.
• BIt is an act or profession of splitting a computer network into subnetworks.
• CIts usability depends on used authentication method and appropriate account configuration.
• DIt 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 - 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. 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.
