Quick Answer
The answer is that objects are permanently deleted after 365 days. This occurs because the S3 lifecycle expiration action, configured at 365 days, instructs Amazon S3 to remove the objects from the 'logs/' prefix entirely once that time period elapses, regardless of any earlier storage class transitions. On the AWS Certified Data Engineer Associate DEA-C01 exam, this question tests your ability to distinguish between lifecycle transitions (which move data between tiers like Standard-IA at 30 days or Glacier at 90 days) and the final expiration action, which is the only rule that actually deletes objects. A common trap is confusing a transition to Glacier with deletion, but expiration is the sole mechanism for removal. Remember the mnemonic: "Transitions move, expiration removes"—so when you see a day count tied to an expiration rule, that object is gone for good.
This DEA-C01 practice question tests your understanding of data store management. 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.
Refer to the exhibit. A data engineer configured the lifecycle policy shown. The 'logs/' prefix contains important audit logs. After 365 days, what happens to the objects?
Objects are permanently deleted.
The expiration action with Days: 365 deletes the objects after 365 days.
Objects are transitioned to Glacier Deep Archive.
Why wrong: The policy transitions to Glacier, not Glacier Deep Archive.
Objects are transitioned to Glacier.
Why wrong: Glacier transition occurs at 90 days, not 365.
Objects are transitioned to Standard-IA.
Why wrong: Standard-IA transition occurs at 30 days, not 365.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Objects are permanently deleted.
Option D is correct because the expiration action deletes objects after 365 days. Option A is wrong because the policy transitions to Glacier, not Deep Archive. Option B is wrong because the transition to Standard IA occurs at 30 days, not 365. Option C is wrong because the transition to Glacier occurs at 90 days, not 365.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
