CompTIA ITF+ (FC0-U61) — Question 78

A systems administrator is setting up a new server using RAID technology. If one hard drive in the array fails, the data is stored on another drive, preventing data loss. Which of the following business continuity concepts does this explain?

Answer options

• A. File backup
• B. Data restoration
• C. Fault tolerance
• D. Restoring access

Correct answer: C

Explanation

The correct answer, Fault tolerance, refers to the ability of a system to continue operating properly in the event of a failure of some of its components. File backup and Data restoration are processes related to saving and retrieving data but do not inherently provide continuous operation during hardware failures. Restoring access pertains to regaining entry to data or systems, which is not directly related to the concept of preventing data loss through redundancy.
