- A
Request an SSL certificate from AWS Certificate Manager (ACM) and import it into CloudFront.
Why wrong: Option A is incorrect because the certificate from ACM should be associated with the CloudFront distribution, not imported. Import implies bringing an external certificate, while ACM issues certificates that are natively integrated with CloudFront.
- B
Enable static website hosting on the S3 bucket and configure the bucket policy to allow HTTPS.
Why wrong: Option B is incorrect because enabling static website hosting on the S3 bucket is not necessary when using CloudFront; CloudFront can serve the content directly from the bucket. Additionally, bucket policies cannot enforce HTTPS at the S3 level; HTTPS is terminated at CloudFront.
- C
Place an Application Load Balancer in front of the S3 bucket and attach an SSL certificate.
Why wrong: Option C is incorrect because placing an ALB in front of the S3 bucket adds unnecessary complexity. CloudFront already provides HTTPS termination and performance benefits through caching, so an ALB is not needed.
- D
Configure the CloudFront distribution to use a custom SSL certificate and set the alternate domain name (CNAME) to www.example.com.
Option D is correct because it involves configuring the CloudFront distribution to use a custom SSL certificate from ACM and setting the alternate domain name to www.example.com, which enables HTTPS access.
SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. 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 hosts a static website on Amazon S3 with public read access. The website uses a custom domain name (www.example.com). The company wants to improve performance for global users and also add HTTPS support. They have already set up a CloudFront distribution with the S3 bucket as the origin. However, users still cannot access the website via HTTPS. What should they do?
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 CloudFront distribution to use a custom SSL certificate and set the alternate domain name (CNAME) to www.example.com.
Option D is correct. To serve HTTPS, CloudFront needs an SSL/TLS certificate associated with it, and the custom domain (www.example.com) must be set as an alternate domain name (CNAME) in the distribution settings. The certificate can be obtained from ACM (must be in the US East (N. Virginia) region) and then associated with the CloudFront distribution. Option A is incorrect because ACM certificates are not imported into CloudFront; they are associated with the distribution. Option B is incorrect because enabling static website hosting on S3 is not required when using CloudFront as a CDN, and bucket policies cannot enforce HTTPS at the S3 level; HTTPS is terminated at CloudFront. Option C is incorrect because placing an Application Load Balancer in front of S3 is unnecessary, as CloudFront already provides HTTPS termination and caching for better performance.
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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
