- A
AWS Global Accelerator
Why wrong: Global Accelerator routes traffic through the AWS global network backbone for improved routing performance but doesn't cache content at edge locations.
- B
Amazon Route 53
Why wrong: Route 53 provides DNS routing and can direct users to the nearest endpoint, but doesn't cache content at edge locations like a CDN.
- C
Amazon CloudFront
CloudFront is AWS's CDN that caches content at 400+ global edge locations, delivering content to users with low latency by serving from the nearest cache.
- D
AWS Transfer Acceleration
Why wrong: S3 Transfer Acceleration speeds up uploads to S3 using CloudFront's edge network — it's the reverse direction (client to S3) and not a general CDN service.

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.
Which AWS service provides a fully managed content delivery network (CDN) that caches content at global edge locations to reduce latency for end users?
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 fully managed content delivery network (CDN) that caches static and dynamic content at global edge locations. By serving cached content from the edge closest to the user, CloudFront significantly reduces latency and improves data transfer speeds for end users.
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.

AWS Global Accelerator
Why it's wrong here

- ✗
AWS Transfer Acceleration
Why it's wrong here
S3 Transfer Acceleration speeds up uploads to S3 using CloudFront's edge network — it's the reverse direction (client to S3) and not a general CDN service.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse AWS Global Accelerator (a network optimization service) with a CDN, because both use edge locations, but Global Accelerator does not cache content—it only optimizes network routing.
Detailed technical explanation
How to think about this question
CloudFront leverages over 600+ Points of Presence (PoPs) globally, each acting as a cache for content such as images, videos, APIs, and static assets. Under the hood, CloudFront supports origin failover, custom SSL certificates, and integration with AWS Shield for DDoS protection, making it suitable for both static and dynamic content delivery with low TTFB (Time to First Byte).
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.
