Selected Answer: B
B. Anycast addressing To achieve the goal of accessing servers based on topographical proximity and having the next closest server respond if the first one does not, the technician should configure Anycast addressing. Anycast is a networking technique where the same IP address is assigned to multiple devices, and the network routes the request to the topologically nearest node with that IP address. In Anycast, multiple servers share the same IP address, and the routing infrastructure directs the request to the nearest available server. If the nearest server is unreachable, the routing protocols redirect the request to the next topographically closest server. So, the correct answer is B. Anycast addressing.

Selected Answer: B
Anycast addressing allows multiple servers to share the same IP address, and when a DNS lookup is requested, the request is routed to the server that is topographically closest to the client. If the nearest server fails to respond, the request is automatically routed to the next closest server.

This is a method that is doing the process of elimination to find it's destination, it is not trying to reach multiple destinations @ the same time as multicast would.

Anycast is a network addressing and routing methodology that directs data packets to the nearest or best-performing server among a group of potential servers.
