The correct answer is that noncurrent versions of objects are permanently deleted after 30 days. This happens because the S3 lifecycle rule explicitly sets the NoncurrentVersionExpiration action to delete noncurrent versions after that number of days, and when an object version is expired by a lifecycle policy, it is removed permanently from the bucket—there is no intermediate archive or transition step for noncurrent versions under this rule. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this concept tests your understanding of how S3 Lifecycle policies handle versioned objects, specifically the difference between expiration (deletion) and transition (moving to another storage class). A common trap is confusing the NoncurrentVersionExpiration action with NoncurrentVersionTransition, which would move older versions to a colder tier like Glacier instead of deleting them. Remember the memory tip: “Expiration erases, transition transfers”—if the rule says “expiration,” expect permanent deletion after the specified days.
SOA-C02 Reliability and Business Continuity Practice Question
This SOA-C02 practice question tests your understanding of reliability and business continuity. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 SysOps administrator creates a CloudFormation stack with the template shown. After 30 days, what happens to noncurrent versions of objects in the bucket?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
They are permanently deleted.
Option A is correct because the lifecycle rule deletes noncurrent versions after 30 days. Option B is wrong because they are deleted, not archived. Option C is wrong because they are deleted, not transitioned. Option D is wrong because they are deleted after 30 days, not immediately.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.

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.
