The answer is Amazon CloudFront and Amazon API Gateway. This combination delivers global low latency by using CloudFront as a content delivery network to cache static content at edge locations worldwide, while API Gateway handles dynamic API responses and integrates seamlessly behind CloudFront, ensuring both static and dynamic content benefit from the same edge-optimized delivery. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of global application architecture and the distinction between regional services and edge-optimized services; a common trap is choosing an Application Load Balancer or S3 alone, which lack the global distribution and caching needed for low latency. Remember the memory tip: “Edge for speed, API for deeds”—CloudFront brings content to the edge, and API Gateway processes the dynamic requests behind it.
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 web application that will be accessed by users worldwide. The application will serve static content (HTML, CSS, images) and dynamic API responses. The company wants to minimize latency for all users. Which combination of AWS services should the company use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon CloudFront and Amazon API Gateway
Amazon CloudFront is a CDN that serves static content from edge locations, and Amazon API Gateway can host the API and integrate with CloudFront. Option A is wrong because S3 alone does not provide CDN. Option B is wrong because ALB is regional. Option D is wrong because Route 53 is DNS only.
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.
CloudFront provides edge caching for static content and can route API requests to API Gateway, reducing latency.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Amazon S3 and Amazon CloudFront
Why it's wrong here
This serves static content but the API would still need a regional endpoint.
✗
Application Load Balancer (ALB) and Amazon CloudFront
Why it's wrong here
ALB is regional; CloudFront can front it, but for API Gateway it's better.
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.

What is the correct answer to this question?
The correct answer is: Amazon CloudFront and Amazon API Gateway — Amazon CloudFront is a CDN that serves static content from edge locations, and Amazon API Gateway can host the API and integrate with CloudFront. Option A is wrong because S3 alone does not provide CDN. Option B is wrong because ALB is regional. Option D is wrong because Route 53 is DNS only.

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.
Are there clue words in this question I should notice?
Yes — watch for: "minimum / minimize". Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.

Static NAT maps one inside address to one outside address.
