SAP-C02 Design for New Solutions Practice Question
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?

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 global content delivery network (CDN) that serves static content (HTML, CSS, images) from edge locations, minimizing latency. For dynamic API responses, CloudFront can route requests to Amazon API Gateway, which acts as a backend to handle API calls. This combination provides low-latency access worldwide for both static and dynamic content. Option A (Route 53 + S3) is incorrect because Route 53 is DNS only and S3 alone does not provide caching at edge locations. Option C (S3 + CloudFront) is missing a managed API service for dynamic responses; while CloudFront can serve static content from S3, it needs API Gateway or a compute origin for dynamic APIs. Option D (ALB + CloudFront) places CloudFront in front of an ALB, but ALB is regional and does not effectively reduce latency for static assets; additionally, ALB is not optimized for API management like API Gateway.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon Route 53 and Amazon S3
Why it's wrong here
Route 53 is DNS; S3 alone is not a CDN.
- ✓
Amazon CloudFront and Amazon API Gateway
Why this is correct
CloudFront provides edge caching for static content and can route API requests to API Gateway, reducing latency.
- ✗
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.
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 |
