CompTIA Server+ (SK0-005) — Question 229

Which of the following concepts is in use when dual power supplies are connected to different power sources?

Answer options

• A. Fault tolerance
• B. Active-passive
• C. Component redundancy
• D. Heartbeat
• E. Link aggregation

Correct answer: A

Explanation

The correct answer is A, as fault tolerance allows a system to remain operational even when one power supply fails. The other options do not pertain specifically to power supply configurations; for instance, active-passive refers to a different type of redundancy setup, while heartbeat and link aggregation involve different networking concepts.
