SY0-701 Security Operations Practice Question
During a disaster recovery test, what is the most important thing to confirm about the backup?
⚠ Common exam trap
Candidates often confuse backup existence with backup usability, assuming that if the backup file is present and encrypted, it must be restorable, but CompTIA emphasizes that only a successful restore test confirms recoverability.

Correct answer & explanation
✓
That the data can be restored and is usable after recovery.
The most important thing to confirm about a backup during a disaster recovery test is that the data can be restored and is usable after recovery. This validates the integrity and completeness of the backup, ensuring that the recovery point objective (RPO) and recovery time objective (RTO) can be met. Simply verifying that backup files exist does not guarantee they are not corrupted or that the restoration process will succeed, which is why a full restore test is critical.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
That the backup files exist in storage.
Why it's wrong here
Simply confirming that backup files exist in storage only validates that a copy operation completed at some point; it does not certify that the data is complete, uncorrupted, or compatible with the recovery environment. Backup files may be silently damaged by bit rot, partial writes, or media degradation, and a restore test is the only way to prove the data can actually be reconstructed and used by business applications.
- ✓
That the data can be restored and is usable after recovery.
Why this is correct
The real purpose of a backup is successful recovery. During testing, the team should verify that the data restores correctly and that applications or users can actually use it afterward. This confirms the backup supports business continuity and is not merely sitting in storage as an unreadable copy.
- ✗
That the backup system uses encryption.
Why it's wrong here
Encryption protects backup data at rest and in transit, but it is a security control, not a recovery control. Encrypted backups can become unrecoverable without the correct decryption keys or if the encryption process introduces corruption, and encryption does not exercise the restore path, validate the recovery procedure, or ensure the restored data is usable. Thus, encryption is necessary for confidentiality but completely insufficient for proving recoverability.
- ✗
That the backup is stored on tape instead of disk.
Why it's wrong here
The choice between tape and disk is a storage tiering decision that affects cost, retention speed, and perhaps access latency, but it has no direct bearing on whether a backup can be successfully restored and used. A restore test measures the integrity of the data and the effectiveness of the recovery workflow, not the physical medium; either tape or disk can fail, and either can produce a valid restore if the backup and recovery procedures are sound.

Key term
RPO
Recovery Point Objective (RPO) is the maximum acceptable amount of data loss measured in time, defining how recent data must be to resume operations after a disruption.
Key term
RTO
Recovery Time Objective is the maximum acceptable time to restore a system or data after a disaster, defining how quickly normal operations must resume.
