Google PCA Object versioning Practice Question
A company uses Cloud Storage for backup data. They want to protect against accidental deletion. Which option is best?
⚠ Common exam trap
Google Cloud often tests the distinction between versioning (which allows recovery from accidental deletion) and retention policies (which prevent deletion but do not provide recovery after the fact), leading candidates to confuse compliance protection with accidental deletion protection.
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
✓
Enable object versioning.
Object versioning in Cloud Storage preserves every version of an object, including overwrites and deletions. When versioning is enabled, a delete operation creates a delete marker instead of permanently removing the object, allowing easy recovery. This directly protects against accidental deletion by retaining all previous object versions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable object versioning.
Why this is correct
Preserves noncurrent versions for recovery.
- ✗
Use a lifecycle policy.
Why it's wrong here
Manages deletion, does not protect against it.
- ✗
Set a retention policy.
Why it's wrong here
Prevents deletion during retention period, but not after.
- ✗
Use object holds.
Why it's wrong here
Object holds prevent deletion or overwrite of an object for a specified duration, but they do not provide recovery of already deleted objects. They are typically used for compliance or legal holds, not for recovering from accidental deletion.
