SAA-C03 Design High-Performing Architectures Practice Question
A globally distributed application needs to provide low-latency access to static content for users around the world. Which AWS service is best suited for this requirement?
⚠ Common exam trap
SAA-C03 often tests the distinction between CloudFront (caching/CDN for HTTP content) and Global Accelerator (network-layer acceleration for TCP/UDP) — candidates pick Global Accelerator thinking 'global' means 'best for global static content'.
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
✓
Amazon CloudFront.
Amazon CloudFront is a global content delivery network (CDN) that caches static content at edge locations worldwide, dramatically reducing latency for geographically distributed users. It integrates natively with S3 origins and supports cache behaviors, signed URLs, and Lambda@Edge for dynamic customization. This makes it the purpose-built service for low-latency global static content 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 Cross-Region Replication.
Why it's wrong here
S3 Cross-Region Replication is used for data redundancy and disaster recovery, not for content delivery. It does not provide the performance-optimized edge location delivery that CloudFront offers. Users would still need to access regional S3 endpoints, which would be slower than fetching from a nearby CloudFront edge location.
- ✓
Amazon CloudFront.
Why this is correct
CloudFront is specifically engineered to deliver content globally with low latency. By distributing content to hundreds of edge locations, it ensures that users receive data from the geographically closest server, significantly reducing round-trip times and providing a high-performance experience that simple regional storage cannot match for global users.
- ✗
AWS Global Accelerator.
Why it's wrong here
Global Accelerator is designed to optimize the path to your applications running on EC2 or Load Balancers by using the AWS global network. It is not designed to cache static content. CloudFront is the correct service for static content delivery, whereas Global Accelerator is for general network traffic and non-HTTP protocols.
- ✗
Amazon Route 53 Geolocation Routing.
Why it's wrong here
Route 53 Geolocation routing helps direct users to specific resources based on their location, but it does not cache or distribute the content itself. It is a traffic management tool. Without an underlying delivery mechanism like CloudFront, the actual data retrieval speed would still be limited by the origin server location.

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 |
