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.
The lifecycle policy shown has a single rule that expires objects in the 'logs/' prefix after 365 days. In Amazon S3, an 'expiration' action permanently deletes the objects once the specified number of days has passed since object creation. There is no transition action configured, so objects are not moved to any storage class; they are simply deleted.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Objects are permanently deleted.
Why this is correct
The expiration action with Days: 365 deletes the objects after 365 days.
Related concept
Read the scenario before looking for a memorised answer.
Objects are transitioned to Glacier Deep Archive.
Why it's wrong here
The policy transitions to Glacier, not Glacier Deep Archive.
Objects are transitioned to Glacier.
Why it's wrong here
Glacier transition occurs at 90 days, not 365.
Objects are transitioned to Standard-IA.
Why it's wrong here
Standard-IA transition occurs at 30 days, not 365.
Common exam traps
The DEA-C01 exam often tests the distinction between 'expiration' (permanent deletion) and 'transition' (moving to another storage class), and candidates mistakenly assume that expiration implies a transition to a cold storage class like Glacier.
Detailed technical explanation
S3 Lifecycle policies evaluate actions in order: transitions occur before expiration if both are defined for the same object. When only expiration is set, S3 permanently removes the object after the specified days, and the object is not recoverable unless versioning or a replication rule is in place. In a real-world scenario, audit logs often require a retention period before deletion, and using expiration without a preceding transition can lead to permanent loss if not carefully planned.
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.
Quick reference
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
