CompTIA A+ Core 1 (220-1101) — Question 293

Which of the following is the best way to protect the data of a virtual machine in the event of hardware failure?

Answer options

• A. Redundant hardware
• B. UPS
• C. Cloud-based backup
• D. RAID

Correct answer: C

Explanation

The correct answer is C, as cloud-based backup offers a reliable solution for data protection by storing copies offsite, ensuring recovery from hardware failures. While A (Redundant hardware) enhances availability and D (RAID) provides fault tolerance for disks, they do not offer the same level of data safety in the event of a total hardware failure. B (UPS) is important for power protection but does not directly address data recovery.
