- A
Use server-side encryption with customer-provided keys (SSE-C).
Why wrong: SSE-C is an option but not the only way; default encryption is simpler and meets the requirement.
- B
Enable default encryption on the S3 bucket using SSE-S3 or SSE-KMS.
Default encryption ensures all objects are encrypted at rest automatically.
- C
Use Amazon CloudFront to serve the images and enforce HTTPS.
Why wrong: CloudFront enforces HTTPS in transit but does not address encryption at rest or public access blocking.
- D
Create a bucket policy that denies uploads without encryption in transit.
Why wrong: Bucket policies can deny requests that are not using HTTPS, but the question asks for encryption at rest and blocking public access.
- E
Configure the S3 Block Public Access settings to block all public access.
This prevents any public access to the bucket and its objects.
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 new application that will use Amazon S3 to store user-uploaded images. The application must enforce that all uploads are encrypted in transit and at rest. Additionally, the bucket must be configured to block all public access. Which TWO actions should be taken to meet these requirements?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enable default encryption on the S3 bucket using SSE-S3 or SSE-KMS.
Option A is correct because enabling S3 default encryption ensures objects are encrypted at rest. Option D is correct because blocking public access via the Block Public Access settings is a bucket-level control. Option B is wrong because bucket policies are not used for encryption. Option C is wrong because CloudFront is not related to S3 encryption. Option E is wrong because SSE-C is client-managed, but the question does not specify client-managed keys.
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 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.
