- A
Regional Edge Caches
Why wrong: Regional Edge Caches are an intermediate cache layer used with CloudFront, but they are not the primary component for delivering content with the lowest latency to global users; edge locations are closer to users.
- B
Availability Zones
Why wrong: Availability Zones are isolated data centers within an AWS Region, designed for high availability and fault tolerance of compute and storage resources, not for caching content at the edge.
- C
Edge Locations
Edge locations are a key part of the AWS global infrastructure, used by services like Amazon CloudFront to cache content geographically close to end users, minimizing latency and improving performance.
- D
AWS Outposts
Why wrong: AWS Outposts brings native AWS services to on-premises data centers; it is not used for globally distributed content caching or delivery.
Quick Answer
The answer is Edge Locations. Edge Locations are part of AWS CloudFront, a content delivery network (CDN) that caches static content like images, videos, and CSS files at geographically distributed points of presence (PoPs) close to end users, which directly reduces latency and improves load times for a global audience. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of the difference between edge locations vs regional edge caches—a common trap is confusing the two, but remember that Edge Locations handle static content caching for immediate user proximity, while Regional Edge Caches have a larger cache and sit between Edge Locations and the origin server. A helpful memory tip: think of Edge Locations as the "front door" for users, providing the fastest first-mile delivery, whereas Regional Edge Caches are the "backup pantry" that reduces load on the origin.
CLF-C02 Cloud Concepts Practice Question
This CLF-C02 practice question tests your understanding of cloud concepts. 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's website serves static content—such as images, videos, and CSS files—to a global audience. The company wants to reduce load times for users located far from the primary AWS Region where the application is hosted. Which component of the AWS global infrastructure is specifically designed to cache and deliver this content with low latency from locations close to end users?

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
Edge Locations
Edge Locations are part of AWS CloudFront, a content delivery network (CDN) that caches static content (e.g., images, videos, CSS) at geographically distributed points of presence (PoPs). When a user requests content, CloudFront serves it from the nearest Edge Location, reducing latency and improving load times for global audiences. This makes Edge Locations the correct choice for caching and delivering static content with low latency.
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 confuse Regional Edge Caches with Edge Locations, thinking that Regional Edge Caches are the primary caching layer for end users, when in fact Edge Locations are the outermost, lowest-latency layer in the CloudFront hierarchy.
Detailed technical explanation
How to think about this question
CloudFront Edge Locations use a pull-through caching mechanism: when a user requests content, the Edge Location checks its cache; if missing (cache miss), it fetches the content from the origin (or a Regional Edge Cache if configured) and then serves it. Regional Edge Caches have larger caches than Edge Locations and are used to reduce the number of requests to the origin, but they are located in the same AWS Region as the origin, not near end users. For truly global low-latency delivery, Edge Locations are the closest PoPs, often within single-digit milliseconds of users in major population centers.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
