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

The correct answer is C. Cloud-based backup. Cloud-based backup stores copies of VM data offsite and off-hardware, meaning that if the physical host server fails completely, the data is still recoverable from the cloud. This is the best protection against hardware failure because the backup exists independently of the faile

Explanation

Cloud-based backup stores copies of VM data offsite and off-hardware, meaning that if the physical host server fails completely, the data is still recoverable from the cloud. This is the best protection against hardware failure because the backup exists independently of the failed hardware. Redundant hardware reduces the likelihood of failure but does not protect data if both redundant components fail or if data becomes corrupted. A UPS protects against power loss but not hardware component failure. RAID protects against individual disk failure but remains on the same physical server - a catastrophic hardware failure (e.g., server fire, motherboard failure) can still result in data loss.
