The answer is enabling versioning and MFA Delete. Versioning protects against accidental deletion or overwrite by preserving every object version, allowing you to restore a previous version if data is deleted or overwritten. MFA Delete adds a required authentication code from a hardware or virtual MFA device before any object version can be permanently deleted, creating a strong safeguard against unauthorized or accidental removal. On the AWS Certified Security Specialty SCS-C02 exam, this question tests your understanding of S3 data protection mechanisms versus features like replication or encryption, which serve different purposes. A common trap is confusing Cross-Region Replication, which is for disaster recovery, with deletion protection. Remember the memory tip: “Versioning saves your past, MFA locks the delete blast.”
SCS-C02 Data Protection Practice Question
This SCS-C02 practice question tests your understanding of data protection. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 is designing a data protection strategy for its Amazon S3 buckets. Which TWO actions can help protect data from accidental deletion or overwrite?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable MFA Delete on the bucket.
The correct answers are A and C. Option A: MFA Delete adds an extra authentication step to delete objects. Option C: Versioning allows recovery of overwritten or deleted objects. Option B: Cross-Region Replication is for disaster recovery, not deletion protection. Option D: Default encryption protects data at rest, not deletion. Option E: Lifecycle policies can delete objects, not protect them.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Read the scenario before looking for a memorised answer.
✗
Enable Cross-Region Replication.
Why it's wrong here
Replicates objects to another region, but does not prevent deletion.
✗
Enable default encryption.
Why it's wrong here
Encrypts data, but does not prevent deletion.
✓
Enable versioning on the bucket.
Why this is correct
Preserves previous versions, allowing recovery.

✗
Set a lifecycle policy to expire objects.
Why it's wrong here
Expiry deletes objects, not protect them.
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.

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.
