Answer: A
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 permanent alternative routing. Standby servers
will not provide continuity if a link is severed.
