SOA-C02 Reliability and Business Continuity Practice Question
This SOA-C02 practice question tests your understanding of reliability and business continuity. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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's S3 bucket contains critical data. The bucket policy allows s3:PutObject and s3:GetObject for all authenticated users in the account. A SysOps administrator needs to ensure that if the bucket is accidentally deleted, the objects can be recovered. Which solution meets this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable versioning on the bucket and enable MFA delete.
Option D is correct because S3 versioning combined with MFA delete protection prevents accidental deletion of versions. Option A is wrong because cross-region replication replicates objects but does not protect against bucket deletion; the replicated bucket could also be deleted. Option B is wrong because a bucket policy cannot prevent deletion of the bucket itself; deletion is controlled by IAM. Option C is wrong because bucket policies do not prevent deletion of the bucket; they only control access to objects.
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.
✗
Set a bucket policy that requires MFA for any s3:DeleteObject action.
Why it's wrong here
This protects object deletion but not bucket deletion.
✗
Add a bucket policy that denies s3:DeleteBucket for all principals.
Why it's wrong here
Bucket policies cannot explicitly deny the DeleteBucket action; IAM policies are needed.
✓
Enable versioning on the bucket and enable MFA delete.
Why this is correct
Versioning preserves all object versions, and MFA delete adds an extra layer of protection, requiring a second factor to permanently delete versions.

✗
Enable cross-region replication on the bucket.
Why it's wrong here
Replication helps with regional disaster recovery but does not prevent the source bucket from being deleted.
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.
Detailed technical explanation
How to think about this question
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.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
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.
