Which of the following steps will NOT make a server fault tolerant? Each correct answer
represents a complete solution. Choose two.

A.
Adding a second power supply unit

B.
Performing regular backup of the server

C.
Adding one more same sized disk as mirror on the server

D.
Implementing cluster servers facility

E.
Encrypting confidential data stored on the server

Explanation:

Encrypting confidential data stored on the server and performing regular backup will not make the
server fault tolerant.
Fault tolerance is the ability to continue work when a hardware failure occurs on a system. A faulttolerant system is designed from the ground up for reliability by building multiples of all critical
components, such as CPUs, memories, disks and power supplies into the same computer. In the
event one component fails, another takes over without skipping a beat.
Answer options A, C, and D are incorrect. The following steps will make the server fault tolerant:
