SAP-C02 Design for New Solutions Practice Question
A company is designing a new static website hosted on Amazon S3. They want to use Amazon CloudFront as a content delivery network (CDN) to serve the website globally with low latency. The website content must be encrypted in transit. Which configurations should they use? (Choose TWO.)
⚠ Common exam trap
Candidates often confuse encryption at rest (S3 default encryption) with encryption in transit, or they assume that CloudFront's default HTTPS support automatically secures the S3 origin connection without needing a bucket policy to enforce it.
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
✓
Configure the S3 bucket policy to deny requests that do not use HTTPS.
Configuring the S3 bucket policy to deny requests that do not use HTTPS ensures that all traffic to the S3 origin is encrypted in transit, preventing data exposure during transit between CloudFront and S3. Option D is correct because configuring CloudFront to require HTTPS for viewer requests enforces encryption between end users and CloudFront, fulfilling the requirement for encryption in transit for the entire delivery path.
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 default encryption on the S3 bucket using AES-256.
Why it's wrong here
Default encryption is for data at rest, not in transit.
- ✗
Enable S3 Transfer Acceleration on the bucket.
Why it's wrong here
Transfer Acceleration speeds up uploads, not encryption.
- ✓
Configure the S3 bucket policy to deny requests that do not use HTTPS.
Why this is correct
This ensures CloudFront uses HTTPS to fetch objects from S3.
- ✓
Configure CloudFront to require HTTPS for viewer requests.
Why this is correct
HTTPS encrypts data between viewer and CloudFront.
- ✗
Use CloudFront signed URLs to restrict access.
Why it's wrong here
Signed URLs control access, not encryption.
