SOA-C02 Networking and Content Delivery Practice Question
A company wants to reduce latency for global users accessing static content stored in Amazon S3. Which AWS service should be used?
⚠ Common exam trap
The trap is confusing S3 Transfer Acceleration (upload acceleration) with CloudFront (download/content delivery) — candidates see 'S3' and 'latency' and pick Transfer Acceleration without noting the direction of traffic.
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 that caches static content at edge locations close to users, dramatically reducing latency for S3-hosted objects. It integrates natively with S3 as an origin and is the standard AWS answer for global static content acceleration.

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
Why it's wrong here
Amazon Route 53 is a DNS service; it translates domain names to IP addresses and supports policies like latency-based routing and health checks, but it does not store or serve content. Even if Route 53 directs a user to a nearby endpoint, the actual static files must be served from that endpoint, which Route 53 cannot do. Because it never caches or delivers payloads, it cannot reduce download latency for global users.
- ✓
Amazon CloudFront
Why this is correct
Amazon CloudFront is a content delivery network that caches static assets such as images, CSS, and JavaScript at edge locations in AWS's global point-of-presence network. When a user requests content, CloudFront serves it from the nearest edge location instead of the origin S3 bucket, which cuts network round-trip time and reduces load on the origin. This behavior directly minimizes latency for global downloads, making it the correct choice for this scenario.
- ✗
S3 Transfer Acceleration
Why it's wrong here
S3 Transfer Acceleration is designed to accelerate uploads into an S3 bucket by routing data over AWS's optimized backbone to the bucket's endpoint. It does not cache or replicate content at edge locations; a download still traverses back to the bucket's AWS region. Therefore, while it can speed up content ingestion, it does not reduce latency for end users downloading cached or static content.
- ✗
AWS Global Accelerator
Why it's wrong here
AWS Global Accelerator uses anycast addresses at AWS edge locations to route traffic over the AWS global network, which improves path stability and performance for TCP/UDP traffic such as APIs and dynamic applications. However, it is not a caching service; each request is proxied to the configured origin endpoint, so static content still comes from the source and is never stored at the edge. Without edge caching, it cannot provide the same latency reduction for repeated static asset downloads as a CDN.

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 |
