Which of the following would BEST ensure continuity of a wide area network (WAN) across the organization?

A. Built-in alternative routing
B. Completing full system backup daily
C. A repair contract with a service provider
D. A duplicate machine alongside each server

Correct Answer: A

Explanation:

Explanation: Alternative routing would ensure the network would continue if a server is lost or if a link is severed as message rerouting could be automatic. System backup will not afford immediate protection. The repair contract is not as effective as perm a nentalte (native routing). Standby servers will not provide continuity if a link is severed.
