- A
Amazon CloudFront
CloudFront caches content at edge locations and reduces latency and origin traffic for global users.
- B
AWS Direct Connect
Why wrong: Direct Connect improves private network connectivity, but it does not provide edge caching for public content.
- C
Amazon Route 53 health checks
Why wrong: Route 53 health checks help with DNS failover, not caching or content delivery performance.
- D
Amazon EFS
Why wrong: EFS is a shared file system service and does not solve global delivery of static web assets.

SAA-C03 Design Secure Architectures Practice Question
This SAA-C03 practice question tests your understanding of design secure architectures. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company hosts static images, CSS, and JavaScript files in an Amazon S3 bucket. Users around the world report slow page loads, and the origin receives many repeated requests for the same files. What should the team use to improve 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
✓
Amazon CloudFront
Amazon CloudFront is a content delivery network (CDN) that caches static content (images, CSS, JavaScript) at edge locations worldwide. By serving cached copies from the edge closest to each user, CloudFront reduces latency, offloads repeated requests from the origin S3 bucket, and improves page load times for a global audience.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 CloudFront
Why this is correct
CloudFront caches content at edge locations and reduces latency and origin traffic for global users.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
AWS Direct Connect
Why it's wrong here
Direct Connect improves private network connectivity, but it does not provide edge caching for public content.
When this WOULD be correct
A company needs a consistent, low-latency connection between its on-premises data center and AWS for large data transfers or real-time applications, and the question specifies hybrid cloud connectivity requirements.
- ✗
Amazon Route 53 health checks
Why it's wrong here
Route 53 health checks help with DNS failover, not caching or content delivery performance.
When this WOULD be correct
A company has a multi-region application deployment and wants to automatically route users to healthy endpoints, failing over if an endpoint becomes unhealthy. In that scenario, Route 53 health checks combined with DNS failover would be the correct answer.
- ✗
Amazon EFS
Why it's wrong here
EFS is a shared file system service and does not solve global delivery of static web assets.
When this WOULD be correct
A question where a company needs a shared file system accessible by multiple EC2 instances for concurrent read/write operations, such as a web application's shared content or a data processing pipeline, with low-latency access within a region.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The SAA-C03 exam frequently reuses these exact scenarios with slightly different constraints.
✓Amazon CloudFrontCorrect answer▾
Why this is correct
CloudFront caches content at edge locations and reduces latency and origin traffic for global users.
✗AWS Direct ConnectWrong answer — click to see why▾
Why this is wrong here
AWS Direct Connect establishes a dedicated network connection from on-premises to AWS, which does not address global latency or repeated requests for static content served from S3.
★ When this WOULD be the correct answer
A company needs a consistent, low-latency connection between its on-premises data center and AWS for large data transfers or real-time applications, and the question specifies hybrid cloud connectivity requirements.
Why candidates choose this
Candidates may think a dedicated connection improves speed for all traffic, but Direct Connect does not provide global edge caching or reduce repeated requests to the origin.
✗Amazon Route 53 health checksWrong answer — click to see why▾
Why this is wrong here
Amazon Route 53 health checks are used to monitor the health of resources and route traffic away from unhealthy endpoints; they do not cache content or reduce repeated requests to the origin, so they cannot improve page load performance for static assets.
★ When this WOULD be the correct answer
A company has a multi-region application deployment and wants to automatically route users to healthy endpoints, failing over if an endpoint becomes unhealthy. In that scenario, Route 53 health checks combined with DNS failover would be the correct answer.
Why candidates choose this
Candidates may think that health checks can somehow optimize performance by directing users to faster endpoints, but health checks only verify availability, not speed, and do not address caching or repeated requests.
✗Amazon EFSWrong answer — click to see why▾
Why this is wrong here
Amazon EFS is a file storage service for EC2 instances, not designed for serving static web content globally or reducing repeated requests. It does not provide edge caching or content delivery acceleration.
★ When this WOULD be the correct answer
A question where a company needs a shared file system accessible by multiple EC2 instances for concurrent read/write operations, such as a web application's shared content or a data processing pipeline, with low-latency access within a region.
Why candidates choose this
Candidates may confuse EFS with S3 for static content storage, or think a shared file system can improve performance by centralizing files, but overlook that EFS lacks global caching and edge delivery capabilities.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse a CDN (CloudFront) with a private network connection (Direct Connect) or a DNS routing service (Route 53), failing to recognize that caching at edge locations is the key to reducing latency and origin load for static content served globally.
Detailed technical explanation
How to think about this question
CloudFront uses a global network of over 600 Points of Presence (PoPs) to cache content at the edge. When a user requests a file, CloudFront checks its cache; if missing, it fetches the object from the S3 origin and caches it based on TTL headers (e.g., Cache-Control max-age). This reduces origin load and improves performance, especially for repeated requests, as subsequent users receive the cached copy without hitting S3.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
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 |
