DEA-C01 Data Operations and Support Practice Question
Network Topology
A data engineer is configuring an S3 bucket for a data lake. The engineer runs the command shown in the exhibit. What does the output indicate about the bucket?
⚠ Common exam trap
DEA-C01 often tests the difference between versioning enabled and suspended; the output 'Enabled' means versioning is active, not suspended.
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
✓
Versioning is enabled on the bucket.
The output of the command (likely 'aws s3api get-bucket-versioning') shows a Status of 'Enabled', indicating that versioning is enabled on the bucket. This means multiple versions of objects are retained.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Versioning is enabled on the bucket.
Why this is correct
The command's output reports a Versioning configuration, and its Status field reads Enabled, confirming that object versions are retained rather than overwritten. This distinguishes versioning from bucket logging, encryption or lifecycle settings, which appear under different configuration keys.
- ✗
The bucket retains only the latest version of each object.
Why it's wrong here
Versioning retains every object version plus delete markers, not just the latest. The output shows versioning enabled, so prior versions persist. Latest-only retention describes a bucket where versioning was never enabled, which is not what the command output indicates.
- ✗
Versioning is suspended on the bucket.
Why it's wrong here
Suspended versioning shows a 'Suspended' status, and new objects receive a null version ID. The exhibit shows 'Enabled', so suspension is not indicated. Suspension is the correct interpretation only when the status field explicitly reads Suspended.
- ✗
MFA Delete is enabled for the bucket.
Why it's wrong here
MFA Delete appears as a separate 'MfaDelete' field in the versioning output, not as the Status value. The exhibit shows Status Enabled, which concerns versioning alone. MFA Delete would be the answer only if that dedicated field read Enabled.
