- A
Amazon CloudFront
CloudFront is a CDN that caches static content at edge locations, reducing latency for users and reducing load on origin servers. It also accelerates dynamic content routing over the AWS backbone.
- B
AWS Global Accelerator
Why wrong: Global Accelerator improves the availability and performance of applications by directing traffic to optimal endpoints over the AWS global network, but it does not cache static content. It is used for TCP/UDP traffic, not for caching objects.
- C
Amazon Route 53
Why wrong: Route 53 is a Domain Name System (DNS) web service. It translates domain names to IP addresses but does not cache web content or offload requests from servers.
- D
AWS Direct Connect
Why wrong: Direct Connect is a dedicated network connection from an on-premises data center to AWS. It provides consistent network performance but does not cache content or serve static assets to users globally.
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 a global e-commerce website hosted on Amazon EC2 instances in the us-west-2 Region. The website includes static assets (product images, CSS, JavaScript) and dynamic content generated by the application. The company wants to improve page load times for users in Europe and Asia by caching static content at edge locations, while also reducing the direct load on the EC2 instances. Which AWS service should the company use?
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 assets (images, CSS, JavaScript) at edge locations worldwide, reducing latency for users in Europe and Asia. By offloading static content delivery from the origin EC2 instances, CloudFront directly reduces the load on those servers, improving overall performance and scalability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Amazon Route 53
Why it's wrong here
Route 53 is a Domain Name System (DNS) web service. It translates domain names to IP addresses but does not cache web content or offload requests from servers.

AWS Direct Connect
Why it's wrong here
Direct Connect is a dedicated network connection from an on-premises data center to AWS. It provides consistent network performance but does not cache content or serve static assets to users globally.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing Global Accelerator (which optimizes network routing for dynamic content) with CloudFront (which caches static content at edge locations), leading candidates to pick Global Accelerator for a caching use case.
Detailed technical explanation
How to think about this question
CloudFront uses a global network of over 600 Points of Presence (PoPs) to cache static content via HTTP/HTTPS GET requests, with cache-control headers (e.g., max-age, ETag) determining freshness. Under the hood, CloudFront supports origin shield to further reduce load on the EC2 origin by aggregating requests from edge locations. A real-world scenario: a product image served from CloudFront in Paris might have a latency of ~10 ms versus ~200 ms from us-west-2, and the EC2 instance sees zero requests for that cached object.
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 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.
