FC0-U71 Practice Question: Ensure that data is not lost if a hard drive fails
A company wants to ensure that data is not lost if a hard drive fails. Which of the following best practices should be implemented?
⚠ Common exam trap
Many exam-takers confuse fault tolerance (like RAID) with backups, but RAID only protects against drive failure, not data loss from corruption or deletion, whereas backups ensure data can be restored regardless of the cause.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Performing regular backups
Regular backups create copies of data that can be restored if the original is lost due to hard drive failure. This directly addresses data loss by providing a recovery point, unlike other options that focus on security or power protection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Using strong passwords
Why it's wrong here
Strong passwords restrict unauthorised account access; they create no secondary copy, so a failed drive still loses the data. It is tempting because password strength is a core access control, and it would be correct where the risk is credential compromise rather than hardware failure.
- ✗
Regularly updating antivirus software
Why it's wrong here
Antivirus software detects and removes malicious code; it does not duplicate data, so a drive failure still destroys it. It is tempting because antivirus is a standard endpoint protection control, and it would be the right choice where the threat is malware infection rather than physical disk failure.
- ✗
Using a surge protector
Why it's wrong here
A surge protector guards against voltage spikes damaging hardware; it provides no copy of the data, so a failed drive still loses everything. It is tempting because surge protection is a genuine hardware-safeguarding measure, and it would be correct where the risk being addressed is electrical damage rather than disk failure.
- ✓
Performing regular backups
Why this is correct
Regular backups copy data to separate media, so a failed hard drive can be replaced and its contents restored. This directly addresses the loss scenario, whereas RAID tolerates a single disk failure but does not protect against deletion, corruption, or site-wide events.
