The answer is Amazon CloudFront. This is the correct choice because CloudFront is a content delivery network (CDN) that caches static content—such as HTML, CSS, and images—at edge locations worldwide, which directly addresses the goal to improve latency for a static website. By serving cached responses from the nearest edge location rather than routing every request back to the EC2 instances behind the Application Load Balancer, CloudFront reduces round-trip time and offloads traffic from the origin. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your understanding of how to use CloudFront as a CDN to cache static content and reduce latency, often appearing as a scenario where you must choose between CloudFront, Global Accelerator, or S3 Transfer Acceleration. A common trap is confusing Global Accelerator (which optimizes network path but does not cache) with CloudFront. Memory tip: think “Edge cache for static” to remember that CloudFront is the service for caching static content at edge locations to reduce latency.
SOA-C02 Networking and Content Delivery Practice Question
This SOA-C02 practice question tests your understanding of networking and content delivery. 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 a static website on Amazon EC2 instances behind an Application Load Balancer. They want to improve latency for users around the world by caching content at edge locations. Which AWS service should they use?
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 (e.g., HTML, CSS, images) at edge locations worldwide, reducing latency for global users by serving cached responses from the nearest edge rather than the origin EC2 instances behind the Application Load Balancer. It integrates directly with ALB as a custom origin, offloading traffic and improving response times for repeated requests.
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
Correct. CloudFront caches content at edge locations, reducing latency and offloading origin servers.
Related concept
Read the scenario before looking for a memorised answer.
✗
AWS Global Accelerator
Why it's wrong here
Incorrect. Global Accelerator improves network performance via the AWS global network but does not cache content.
✗
AWS Direct Connect
Why it's wrong here
Incorrect. Direct Connect provides a private, high-bandwidth connection between on-premises and AWS, not edge caching.
✗
Amazon Route 53
Why it's wrong here
Incorrect. Route 53 is a DNS service that routes traffic but does not cache content.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing AWS Global Accelerator (which optimizes network path but does not cache) with CloudFront (which caches at edge), leading candidates to pick Global Accelerator for latency improvement without recognizing the requirement for content caching.
Detailed technical explanation
How to think about this question
CloudFront caches objects at edge locations based on cache-control headers (e.g., max-age, s-maxage) and supports origin shield to reduce load on the ALB. Under the hood, CloudFront uses a global network of over 600 Points of Presence (PoPs) and serves content over HTTP/HTTPS, with support for custom error responses and signed URLs. In a real-world scenario, a static website with global users would see latency drop from hundreds of milliseconds (cross-region) to single-digit milliseconds for cached assets.

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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
