SCS-C02 Data Protection Practice Question

This SCS-C02 practice question tests your understanding of data protection. 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 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.

A
Enable S3 Versioning and enable S3 Object Lock in Compliance mode
Why wrong: Object Lock in Compliance mode prevents both deletion and overwriting, but without a retention period it does not guarantee the 7-year retention requirement. Additionally, Compliance mode cannot be overridden, which may be too restrictive.
B
Use S3 Intelligent-Tiering and lifecycle policies
Why wrong: S3 Intelligent-Tiering and lifecycle policies manage storage classes and costs; they do not prevent accidental deletion or overwriting.
C
Enable S3 Versioning and MFA Delete
Why wrong: Versioning and MFA Delete protect against accidental deletion and preserve versions, but they do not enforce a specific retention period; without lifecycle policies, data may be retained indefinitely or deleted before 7 years.
D
Enable S3 Object Lock in Governance mode and configure a lifecycle policy to expire objects after 7 years
Object Lock in Governance mode prevents deletion and overwriting during the retention period, and a lifecycle policy can expire objects after exactly 7 years, satisfying the requirement.

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. S3 Object Lock in Governance mode prevents objects from being deleted or overwritten during the retention period, and a lifecycle policy can automatically expire objects after 7 years to meet the retention requirement. Option A is incorrect because Object Lock in Compliance mode also prevents deletion and overwriting, but without specifying a retention period, it does not enforce the 7-year retention; additionally, Compliance mode cannot be overridden, which may be too restrictive. Option B is incorrect because S3 Intelligent-Tiering and lifecycle policies manage storage costs and transitions, not protection against deletion or overwriting. Option C is incorrect because versioning and MFA Delete protect against accidental deletion and preserve overwritten versions, but do not guarantee a 7-year retention period; lifecycle policies would be needed to enforce it.

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.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
