- A
Amazon CloudFront
CloudFront is correct because it provides caching of static assets at edge locations and accelerates dynamic content via optimized routing, addressing both latency requirements for a global audience.
- B
AWS Global Accelerator
Why wrong: Global Accelerator improves latency for TCP/UDP traffic by routing users to the nearest edge location and then over the AWS global network, but it does not cache static content. It is not the best choice for serving cached images.
- C
Amazon S3 Transfer Acceleration
Why wrong: S3 Transfer Acceleration is designed to speed up data uploads to Amazon S3 buckets, not to accelerate content delivery to end users. It does not cache content or accelerate API responses.
- D
Application Load Balancer
Why wrong: An Application Load Balancer distributes incoming traffic across targets (e.g., EC2 instances) within a single region. It does not cache content or reduce latency for users located far from the region.
Quick Answer
The answer is Amazon CloudFront. This service is the correct choice because it functions as a content delivery network (CDN) that caches static assets like images and CSS files at edge locations worldwide, directly reducing latency for users in Europe and Asia. For dynamic API content, CloudFront accelerates responses by routing requests over the optimized AWS global network backbone, using features like TCP optimizations and origin shield to improve performance. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of how CloudFront serves both static and dynamic content at the edge, often appearing as a scenario where you must distinguish it from services like S3 Transfer Acceleration or Global Accelerator. A common trap is assuming Global Accelerator is needed for dynamic APIs, but CloudFront handles both use cases natively. Memory tip: think of CloudFront as the "front door" that caches the heavy stuff (static) and speeds up the live traffic (dynamic) using AWS’s private highway.
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. 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 runs an e-commerce application on Amazon EC2 instances in the us-east-1 Region. The application serves static assets (images, CSS files) and dynamic API responses. Users in Europe and Asia report that the website loads slowly, especially for images. The company needs a solution that reduces latency for both static and dynamic content by caching static assets at edge locations and accelerating dynamic API calls using optimized network paths. Which AWS service should the company use?

Correct answer & explanation
Amazon CloudFront
Amazon CloudFront is a content delivery network (CDN) that caches static assets (images, CSS files) at edge locations worldwide, reducing latency for users in Europe and Asia. It also supports dynamic API acceleration by using optimized network paths (AWS global network backbone) and features like origin shield and TCP optimizations, making it the correct choice for both static and dynamic content.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Amazon S3 Transfer Acceleration
Why it's wrong here
S3 Transfer Acceleration is designed to speed up data uploads to Amazon S3 buckets, not to accelerate content delivery to end users. It does not cache content or accelerate API responses.
- ✗
Application Load Balancer
Why it's wrong here
An Application Load Balancer distributes incoming traffic across targets (e.g., EC2 instances) within a single region. It does not cache content or reduce latency for users located far from the region.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse AWS Global Accelerator (which optimizes dynamic traffic only) with CloudFront (which handles both caching and acceleration), failing to recognize that caching static assets is a requirement that only a CDN like CloudFront can fulfill.
Detailed technical explanation
How to think about this question
CloudFront uses over 600 Points of Presence (PoPs) globally to cache static content, reducing origin load and latency. For dynamic API calls, CloudFront leverages the AWS global backbone and persistent TCP connections (e.g., TCP termination at the edge, TLS session reuse) to minimize round-trip time and improve throughput, which is critical for real-time e-commerce interactions.
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.
