A network administrator has purchased two devices that will act as failovers for each other. Which of the following concepts does this BEST illustrate?

A.
Authentication

B.
Integrity

C.
Confidentiality

D.
Availability

Explanation:
Failover refers to the process of reconstructing a system or switching over to other systems when a failure is detected. In the case of a server, the server switches
to a redundant server when a fault is detected. This strategy allows service to continue uninterrupted until the primary server can be restored. In the case of a
network, this means processing switches to another network path in the event of a network failure in the primary path. This means availability.
Incorrect Answers:
A: Authentication is used to verify that a person who sent the message is actually who they say they are.
B: Integrity means that data cannot be tampered with or altered without detection.
C: Confidentiality means that data retains its privacy.
