The answer is that S3 Object Lock with a retention period exceeding 30 days is the most likely cause of the lifecycle policy failing to delete objects. S3 Object Lock enforces a Write Once, Read Many (WORM) model, and when a retention period—either via a retention mode or a legal hold—is active, it overrides lifecycle expiration rules because the object cannot be deleted or overwritten until that retention period expires. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your understanding of how S3 protections interact, often appearing as a trap where candidates assume versioning or permissions are the issue. A common memory tip is to remember that Object Lock acts as a "digital padlock" that lifecycle policies cannot break, so if your S3 lifecycle policy not deleting objects after 30 days, always check for an active retention period first.
SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is using Amazon S3 to store critical data and needs to ensure that objects are automatically deleted after 30 days. The current lifecycle policy is configured to expire objects after 30 days, but objects are not being deleted. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The bucket has S3 Object Lock enabled with a retention period exceeding 30 days.
Option C is correct because S3 Lifecycle policies require proper permissions to execute actions. Option A is wrong because S3 Object Lock can prevent deletion if retention period is set. Option B is wrong because versioning does not prevent lifecycle expiration; expired delete markers are removed. Option D is wrong because storage class transitions do not affect expiration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The bucket has versioning enabled, and lifecycle rules apply only to current versions.
Why it's wrong here
Lifecycle rules can apply to both current and noncurrent versions.
✗
The objects are stored in the S3 Glacier Deep Archive storage class.
Why it's wrong here
Storage class does not affect lifecycle expiration.
✓
The bucket has S3 Object Lock enabled with a retention period exceeding 30 days.
Why this is correct
Object Lock prevents object deletion before retention expires.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The IAM role used by S3 Lifecycle lacks the s3:DeleteObject permission.
Why it's wrong here
Lifecycle actions are performed by S3 internally, not by an IAM role.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
