SAA-C03 Design High-Performing Architectures Practice Question
A company wants to improve the performance of its static website hosted on S3. Which strategy provides the most significant performance gain for global users?
⚠ Common exam trap
Candidates often select S3 Cross-Region Replication, thinking it optimizes performance, when it is actually a disaster recovery feature. CloudFront is needed for global caching and performance.
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
✓
Use Amazon CloudFront with the S3 bucket as the origin.
Static websites hosted on S3 are limited by the speed of the browser-to-bucket connection. By placing an Amazon CloudFront distribution in front of the S3 bucket, content is cached at edge locations globally. This brings the content closer to the users, reducing the distance data travels and minimizing latency, which results in faster page load times regardless of where the user is located geographically.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable S3 Transfer Acceleration on the bucket.
Why it's wrong here
S3 Transfer Acceleration is designed to speed up uploads to S3, not downloads or static website hosting for end users. It utilizes the AWS edge network to ingest data into the AWS network, which is useful for large file transfers but does not optimize website content delivery performance.
- ✗
Configure the S3 bucket to use Multi-Region replication.
Why it's wrong here
Multi-Region replication is used for disaster recovery and data compliance, not for content delivery performance. While it keeps data in different regions, it does not provide a mechanism to deliver that content to the end user with low latency, as CloudFront does through edge location caching.
- ✓
Use Amazon CloudFront with the S3 bucket as the origin.
Why this is correct
CloudFront caches static files at hundreds of edge locations worldwide. This drastically reduces latency for global users by serving content from the nearest edge location rather than the origin S3 bucket. This is the industry-standard architecture for high-performance delivery of static web content.
- ✗
Upgrade the S3 storage class to S3 Intelligent-Tiering.
Why it's wrong here
S3 storage classes are meant for cost optimization based on access patterns, not for performance enhancement. Moving between storage classes does not impact the speed at which files are served to users. Performance is primarily driven by how close the content is to the user, which CloudFront manages.

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 |
