Continuous Improvement for Existing SolutionseasyMultiple ChoiceObjective-mapped

Quick Answer

The answer is to configure the CloudFront distribution to use a custom SSL certificate and set the alternate domain name (CNAME) to www.example.com. This is correct because CloudFront acts as a reverse proxy that terminates HTTPS at the edge, requiring its own SSL/TLS certificate associated with the custom domain, rather than relying on the S3 bucket’s native HTTPS support. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of CloudFront’s integration with AWS Certificate Manager (ACM) and the critical requirement that ACM certificates for CloudFront must be provisioned in the US East (N. Virginia) region, even if the distribution serves global users. A common trap is assuming S3’s HTTPS endpoint alone suffices, but CloudFront needs its own certificate and the alternate domain name configured in the distribution settings. Memory tip: “CloudFront needs its own cert, in Virginia, with a CNAME match.”

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. An SSL/TLS certificate must be associated with the CloudFront distribution, and the custom domain must be configured in the distribution settings. Option A: S3 supports HTTPS but CloudFront needs its own certificate. Option B: ELB is not needed for static websites. Option C: ACM certificates can be used but must be in US East (N. Virginia) region for CloudFront.

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.

  • Request an SSL certificate from AWS Certificate Manager (ACM) and import it into CloudFront.

    Why it's wrong here

    ACM certificates for CloudFront must be in us-east-1 region, but the step is correct; however, also need to configure the distribution to use the certificate.

  • Enable static website hosting on the S3 bucket and configure the bucket policy to allow HTTPS.

    Why it's wrong here

    S3 static website hosting supports HTTPS, but CloudFront requires its own certificate.

  • Place an Application Load Balancer in front of the S3 bucket and attach an SSL certificate.

    Why it's wrong here

    ALB cannot be placed in front of S3; it's for EC2 or IP targets.

  • Configure the CloudFront distribution to use a custom SSL certificate and set the alternate domain name (CNAME) to www.example.com.

    Why this is correct

    This enables HTTPS on CloudFront with the custom domain.

    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 SAP-C02 NAT questions on configuration and troubleshooting.
