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
✓
Encrypt all backup data with strong encryption and restrict decryption keys to authorized personnel.
Option D is correct because encrypting the backup data and restricting decryption keys ensures that even if the tapes are physically stolen, the data remains unintelligible without the keys. Option A (password protection) can often be bypassed and does not secure the data itself. Option B only secures transport, not storage. Option C provides physical security but would not deter a determined thief and does not protect the data if the safe is compromised.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Encrypt all backup data with strong encryption and restrict decryption keys to authorized personnel.
Why this is correct
Encryption is the only measure that directly protects data confidentiality even if physical media is stolen, as decryption requires the keys.
- ✗
Password-protect the tapes and keep them in a locked safe.
Why it's wrong here
Password protection is weak and can be circumvented; a safe may be broken into; data on the tapes would still be readable if extracted.
- ✗
Store tapes in a fireproof safe and limit access to key personnel.
Why it's wrong here
Limiting access reduces risk but insiders or forced entry could still lead to theft; data on tapes remains unencrypted and readable.
- ✗
Use a bonded courier service for transportation.
Why it's wrong here
This only secures the tapes during transit, not while stored at the offsite facility. It does not prevent data access if tapes are stolen later.
