DEA-C01 Data Store Management Practice Question
Network Topology
A data engineer runs the above command and gets the output. What does the 'MFADelete' setting imply?
⚠ Common exam trap
The DEA-C01 exam often tests the distinction between 'MFA Delete' (which only applies to permanent version deletion) and general MFA enforcement on all bucket operations, leading candidates to overgeneralize the scope of the setting.
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
✓
To permanently delete a version of an object, the user must provide MFA.
The 'MFADelete' setting on an S3 bucket versioning configuration requires multi-factor authentication to permanently delete an object version. This means that when a user issues a DELETE request with a version ID (a permanent delete), they must include a valid MFA token in the request headers. It does not apply to creating new versions, reading objects, or other operations.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Any modification to an object requires MFA.
Why it's wrong here
Only version deletion and versioning suspension require MFA.
- ✓
To permanently delete a version of an object, the user must provide MFA.
Why this is correct
MFADelete adds an extra layer of security for version deletions.
- ✗
MFA is required for all read operations as well.
Why it's wrong here
Read operations do not require MFA.
- ✗
All operations on the bucket require MFA authentication.
Why it's wrong here
MFADelete only applies to version deletion and changing versioning state.
