CV0-004 Practice Question: Which TWO actions should a cloud administrator…
Which TWO actions should a cloud administrator take to protect against data exfiltration from a cloud storage bucket? (Choose two.)
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 server-side encryption with SSE-S3.
Enabling object versioning allows recovery if data is deleted or overwritten but does not prevent exfiltration. Requiring MFA for delete operations prevents unauthorized deletion but not reading. Restricting public access and encrypting data at rest are effective controls against exfiltration. Audit logging is detective, not preventive.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement server-side encryption with SSE-S3.
Why this is correct
Encryption protects data at rest; even if exfiltrated, the data is unreadable without the key.
- ✗
Enable object versioning on the bucket.
Why it's wrong here
Versioning helps with data recovery, not prevention of unauthorized access.
- ✗
Configure bucket access logs for monitoring.
Why it's wrong here
Logging is detective but does not prevent exfiltration.
- ✓
Block all public access by configuring bucket policies and ACLs.
Why this is correct
Public access is a common vector; blocking it reduces exposure.
- ✗
Enable MFA delete on the bucket.
Why it's wrong here
MFA delete protects against unauthorized deletion, not reading or copying data.
