Quick Answer
The answer is to implement Amazon CloudFront, AWS Global Accelerator, and a larger EC2 instance type like c5n or m5n to improve performance for a global web application. CloudFront caches both static and dynamic content at edge locations, drastically reducing latency by serving data from points closer to users. Global Accelerator routes traffic over the AWS global network instead of the public internet, minimizing jitter and packet loss for a more consistent user experience. Meanwhile, selecting a larger instance with higher network bandwidth, such as the c5n or m5n family, eliminates network bottlenecks for high-throughput workloads. On the SAA-C03 exam, this scenario tests your ability to combine edge caching, optimized routing, and compute scaling for global latency reduction—a common trap is to overlook dynamic content caching or to rely solely on instance upgrades. Remember the memory tip: “Edge, Route, Compute” for CloudFront, Global Accelerator, and enhanced EC2 networking.
SAA-C03 Design High-Performing Architectures Practice Question
This SAA-C03 practice question tests your understanding of design high-performing 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 is designing a high-performance web application that serves static and dynamic content to a global user base. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The static assets are stored in an S3 bucket. Which three architecture decisions will improve performance and reduce latency for users? (Choose three.)

Correct answer & explanation
✓
Use Amazon CloudFront to cache both static and dynamic content at edge locations.
Amazon CloudFront caches both static and dynamic content at edge locations, reducing latency by serving content from locations closer to users. AWS Global Accelerator improves performance by routing traffic over the AWS global network instead of the public internet, reducing jitter and latency. Larger EC2 instance types like c5n or m5n provide higher network bandwidth, which reduces network bottlenecks for high-traffic applications.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse S3 Transfer Acceleration as a solution for faster downloads, when it only accelerates uploads, or think Multi-AZ RDS provides read scaling, when it is for failover only.
Detailed technical explanation
How to think about this question
CloudFront supports dynamic content caching by forwarding requests to the origin (ALB) and caching responses based on cache-control headers, while Global Accelerator uses Anycast IPs to direct traffic to the nearest edge location and then over the AWS backbone. Larger instance types like c5n leverage Elastic Network Adapter (ENA) with up to 100 Gbps network bandwidth, reducing packet loss and latency under load. S3 Transfer Acceleration uses AWS edge locations for uploads via the HTTP PUT protocol, not for GET/downloads, so it is irrelevant for serving static assets.
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.
