When the server has a tape backup device, you may do away with RAID. T/F?
Correct Answer
B. False
Explanation
RAID is very much essential for online data storage fault tolerance.
13.
The DNS server uses broadcast method first to determine IP to Host resolution. T/F?
Correct Answer
B. False
Explanation
The DNS service will first refer its cache, then the database and so on to perform resolution. Broadcast is employed only when the DNS service fails to fulfill the resolution.
14.
A Server configuration cannot boot from IDE devices. T/F?
Correct Answer
B. False
Explanation
A server configuration can boot from IDE device, but IDE cannot provide the fault tolerance needed by the Server.
