SAP-C02 Design for New Solutions Practice Question
A company needs to provide a global content delivery solution with low latency. Which AWS service should they use?
⚠ Common exam trap
It's easy for candidates to confuse Amazon S3's static website hosting or Route 53's latency-based routing with actual content delivery, but neither provides the edge caching and global distribution that CloudFront offers for low-latency delivery.

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
✓
Amazon CloudFront
Amazon CloudFront is a global content delivery network (CDN) that caches content at edge locations worldwide, reducing latency by serving data from the nearest edge to the user. It integrates with origins like S3, EC2, or on-premises servers and supports both static and dynamic content acceleration, making it the correct choice for low-latency global delivery.
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 S3
Why it's wrong here
S3 is object storage, not a CDN.
- ✗
Amazon EC2
Why it's wrong here
EC2 is compute, not a CDN.
- ✗
Amazon Route 53
Why it's wrong here
Route 53 resolves DNS names and can apply latency-based routing, but it does not cache or serve content, so the request still travels to the origin Region. It is tempting because latency records appear to reduce latency, yet only CloudFront's edge locations actually shorten the data path.
- ✓
Amazon CloudFront
Why this is correct
Amazon CloudFront caches content at edge locations worldwide, delivering objects from the point of presence nearest each user. This directly satisfies the low-latency requirement by shortening the network path, rather than serving every request from a single regional origin. It also integrates with AWS Shield and AWS WAF for protection at the edge.
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 |
