CV0-004 Object Lock Practice Question
A financial services company is subject to strict compliance requirements. They need to ensure that all cloud storage objects are written to a write-once-read-many (WORM) state for a defined retention period. Which feature should be enabled?
⚠ Common exam trap
CompTIA often tests the distinction between features that manage object versions (versioning) versus those that enforce legal holds or retention (Object Lock). Candidates may incorrectly choose Lifecycle policies for compliance, but only Object Lock provides true WORM immutability.
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
✓
Object lock
Object Lock is the correct feature for WORM compliance because it enforces a write-once-read-many (WORM) state on objects, preventing modification or deletion until the specified retention period expires. Lifecycle policies manage data transitions and deletions but do not provide immutability guarantees required for strict compliance.
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
Why it's wrong here
Versioning preserves prior object versions but permits overwrites and deletions, so it does not enforce immutability for a retention period. It is tempting because it protects against accidental loss, yet WORM compliance demands an object lock or retention policy that blocks modification.
- ✓
Object lock
Why this is correct
Object lock enforces WORM protection by preventing object modification or deletion for a defined retention period, meeting the compliance requirement. It satisfies the write-once-read-many constraint directly at the storage-object level, unlike versioning or lifecycle rules.
- ✗
Replication
Why it's wrong here
Replication copies objects to another region or bucket for durability and availability; it does not lock objects against modification or deletion. WORM retention requires an S3 Object Lock or equivalent immutability policy with a retention period. Replication is tempting when the goal is disaster recovery or cross-region redundancy, not compliance immutability.
- ✗
Lifecycle policies
Why it's wrong here
Lifecycle policies transition or expire objects between storage classes; they do not lock objects against modification. They are tempting because retention periods appear in lifecycle rules, but WORM immutability requires a retention lock or bucket lock feature instead.
