CompTIA ITF+ (FC0-U61) — Question 239

Which of the following business continuity concepts is the best example of fault tolerance?

Answer options

• A. Data restoration
• B. Redundant power
• C. Disaster recovery
• D. Restoring access

Correct answer: B

Explanation

Redundant power is the best example of fault tolerance because it ensures that systems remain operational even if one power source fails. Data restoration, disaster recovery, and restoring access do not directly prevent system outages caused by hardware failures, making them less relevant to fault tolerance.
