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.
Network Topology
The exhibit shows the lifecycle configuration for an S3 bucket. Objects in the bucket are 200 days old on average. What will happen to the objects?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Objects are in GLACIER now and will be deleted after 365 days from creation.
The lifecycle configuration shows a current version action to transition to GLACIOR (a misspelling of GLACIER) immediately (0 days after creation) and an expiration action to permanently delete the object 365 days after creation. Since the objects are already 200 days old on average, they have already been transitioned to GLACIER storage class. The expiration rule will delete them 365 days from their creation date, not from the current time.
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.
✗
Objects will be transitioned to GLACIER after 90 days and deleted after 365 days.
Why it's wrong here
The transition already happened; objects will be deleted after 365 days from creation.
✓
Objects are in GLACIER now and will be deleted after 365 days from creation.
Why this is correct
At 200 days, objects have been transitioned; expiration is at 365 days.

✗
Objects will be transitioned to GLACIER after 200 days and deleted after 365 days.
Why it's wrong here
Transition already occurred at 90 days.
✗
Objects will be deleted after 90 days.
Why it's wrong here
The rule transitions to GLACIER after 90 days, not delete.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates misinterpret the '0 days' transition as 'no transition' or assume the average age of 200 days means the transition hasn't happened yet, when in fact the lifecycle rules are based on creation date, not current age.
Detailed technical explanation
How to think about this question
S3 Lifecycle policies evaluate the 'Days' value relative to the object's creation date. A transition action with 0 days means objects are moved to the target storage class as soon as they are created, subject to the 24-hour minimum for lifecycle transitions. The expiration action permanently removes the object after the specified number of days from creation, and this deletion is irreversible. In this scenario, the average age of 200 days confirms the transition has already occurred, and the objects are now in GLACIER, awaiting deletion at day 365.

TExam Day Tips
→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.

What is the correct answer to this question?
The correct answer is: Objects are in GLACIER now and will be deleted after 365 days from creation. — The lifecycle configuration shows a current version action to transition to GLACIOR (a misspelling of GLACIER) immediately (0 days after creation) and an expiration action to permanently delete the object 365 days after creation. Since the objects are already 200 days old on average, they have already been transitioned to GLACIER storage class.
