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

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.
