Correct answer & explanation
✓
Disable MFA Delete by using the AWS CLI with the --mfa parameter and then suspend versioning.
To suspend versioning on an S3 bucket with MFA Delete enabled, you must first disable MFA Delete using the root account (or an account with appropriate permissions). The AWS CLI with the --mfa parameter is used to authenticate with MFA when performing sensitive operations, but disabling MFA Delete requires the root account. After disabling MFA Delete, versioning can be suspended. Option B is incorrect because the AWS Management Console does not bypass MFA Delete; you still need to disable MFA Delete first. Option C is incorrect because deleting and recreating the bucket is unnecessarily disruptive and versioning can be suspended directly after disabling MFA Delete. Option D is incorrect because the error is due to MFA Delete being enabled, not a bucket policy issue.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Disable MFA Delete by using the AWS CLI with the --mfa parameter and then suspend versioning.
Why this is correct
MFA Delete must be disabled first; this requires the root account and MFA device.
- ✗
Use the AWS Management Console to suspend versioning, as it bypasses MFA Delete.
Why it's wrong here
The console also enforces MFA Delete; the error would persist.
- ✗
Delete the bucket and recreate it without versioning.
Why it's wrong here
This would cause data loss and is not a recommended practice.
- ✗
Add a bucket policy to allow versioning suspension.
Why it's wrong here
Bucket policies do not override the MFA Delete requirement.
