The answer is to enable S3 Object Lock in Governance mode and configure a lifecycle policy to expire objects after 7 years. This combination works because Governance mode allows authorized users to temporarily adjust retention settings while preventing any user—including the root account—from deleting or overwriting the object until the retention period expires, and the lifecycle policy handles automatic deletion after the mandated 7-year retention window. On the AWS Certified Security Specialty SCS-C02 exam, this scenario tests your understanding of how Object Lock’s retention modes (Governance vs. Compliance) interact with lifecycle actions; a common trap is choosing only a bucket policy or versioning, which prevents deletion but not overwriting, or selecting Compliance mode, which locks settings so tightly that even the account root cannot modify them. Remember the memory tip: “Governance gives you wiggle room, Compliance locks the tomb.” For long-term data protection against both accidental deletion and overwriting, always pair Object Lock with a lifecycle expiration rule.
SCS-C02 Data Protection Practice Question
This SCS-C02 practice question tests your understanding of data protection. 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.
A company needs to protect sensitive data in Amazon S3 from accidental deletion or overwriting. The data must be retained for at least 7 years after creation. Which combination of S3 features should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable S3 Object Lock in Governance mode and configure a lifecycle policy to expire objects after 7 years
Option D is correct because Object Lock with Governance mode prevents deletion, and lifecycle policies can expire objects after 7 years. Option A only prevents deletion, not overwriting. Option B only protects against accidental deletion. Option C only manages storage classes.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable S3 Versioning and enable S3 Object Lock in Compliance mode
Why it's wrong here
Compliance mode is too strict and cannot be removed, even by the root user.
✗
Use S3 Intelligent-Tiering and lifecycle policies
Why it's wrong here
Intelligent-Tiering does not prevent deletion.
✗
Enable S3 Versioning and MFA Delete
Why it's wrong here
MFA Delete prevents deletion but not overwriting without versioning.
✓
Enable S3 Object Lock in Governance mode and configure a lifecycle policy to expire objects after 7 years
Why this is correct
Governance mode allows some users to bypass lock if needed, and lifecycle expiration can delete after retention period.
Clue confirmation
The clue word "least" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SCS-C02 NAT questions on configuration and troubleshooting.

Option A only prevents deletion, not overwriting. Option B only protects against accidental deletion. Option C only manages storage classes.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company needs to protect data stored in S3 from accidental deletion by users. Which S3 feature should be used?
easy
A.S3 Lifecycle policies
B.S3 MFA Delete
✓ C.S3 Versioning
D.S3 Block Public Access
Why C: Option B is correct because S3 Versioning allows retrieval of overwritten or deleted objects. Option A is incorrect because MFA Delete protects against deletion but is not the primary protection against accidental deletion. Option C is incorrect because S3 Block Public Access prevents public access, not deletion. Option D is incorrect because S3 Lifecycle policies manage storage classes, not deletion protection.
Variation 2. A company is implementing a data protection strategy for Amazon S3. Which TWO actions should be taken to protect data from accidental deletion or overwrite?
medium
A.Enable cross-region replication
✓ B.Enable MFA Delete on the bucket
C.Apply a bucket policy that denies s3:DeleteObject
✓ D.Enable S3 Versioning on the bucket
E.Enable default encryption on the bucket
Why B: Options B and D are correct. Enable versioning to preserve previous versions, and enable MFA Delete to require multi-factor authentication for deletions. Option A is wrong because bucket policies alone do not prevent deletion. Option C is wrong because encryption does not prevent deletion. Option E is wrong because replication does not protect against deletion in the source bucket.
