SK0-005 security-disaster-recovery Practice Question
A company performs annual disaster recovery tests. The last test revealed that the recovery time objective (RTO) was not met because the backup tapes were corrupted. The backup administrator proposes changes to the backup verification process. Which practice is MOST effective to ensure recoverability?
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
✓
Implement automated integrity checks and periodic test restores.
Option B is correct because automated integrity checks and periodic test restores directly validate that backups are usable and meet recovery objectives, catching corruption early. Option A is wrong because increasing backup frequency does not verify that backups are error-free. Option C is wrong because verifying tapes before offsite storage reduces risk but does not guarantee ongoing media integrity; tapes can degrade over time. Option D is wrong because switching to disk-based backups avoids some tape-specific issues but still requires verification processes to ensure data is not corrupted.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Perform a full backup more frequently.
Why it's wrong here
Frequency does not ensure the backups themselves are free from corruption; a corrupted backup is still corrupted regardless of how often it is made.
- ✓
Implement automated integrity checks and periodic test restores.
Why this is correct
Integrity checks (e.g., checksums) verify that backup data matches the expected state, and test restores confirm that the data can actually be recovered, addressing both media and logical corruption.
- ✗
Switch to disk-based backups exclusively.
Why it's wrong here
Disk-based backups are not immune to corruption (e.g., silent data corruption, file system errors) and still require verification procedures.
- ✗
Store backup tapes offsite only after verification.
Why it's wrong here
This ensures initial readability but does not protect against later degradation or corruption that can occur during storage.
