- A
Amazon CloudFront
Why wrong: Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations to improve delivery of static and dynamic web content. However, it is optimized for HTTP/HTTPS traffic and does not provide the same low-latency routing for non-HTTP protocols or for dynamic applications that cannot be cached. The scenario requires routing user traffic over the AWS global network to the closest edge location for any IP traffic, which is a capability of AWS Global Accelerator, not CloudFront.
- B
AWS Global Accelerator
AWS Global Accelerator is designed to improve the performance of global applications by directing user traffic over the AWS global network to the closest edge location. It uses anycast IP addresses and routes traffic to the optimal endpoint based on location, network conditions, and health. This reduces latency and packet loss for global users, making it the correct choice for the described requirements.
- C
Amazon Route 53 (with latency-based routing)
Why wrong: Amazon Route 53 latency-based routing is a DNS-based routing policy that directs user requests to the AWS region with the lowest latency. However, DNS responses can be cached by intermediate resolvers, leading to suboptimal routing. Additionally, DNS routing only works at the DNS query level and does not directly optimize the network path for the actual traffic. AWS Global Accelerator provides more consistent and granular performance improvements.
- D
AWS Direct Connect
Why wrong: AWS Direct Connect provides a dedicated private network connection from an on-premises data center to AWS, which can improve latency and security for traffic between the customer's network and AWS. However, it does not address the performance of global users accessing the application from different parts of the world. Direct Connect is typically used for hybrid cloud scenarios, not for improving global end-user experience.
Quick Answer
AWS Global Accelerator is the correct choice because it uses the AWS global network to reduce latency for global users by routing traffic over the AWS backbone to the closest edge location via Anycast IP addresses. This service optimizes the path from users to the application, sending traffic to the nearest edge endpoint and then forwarding it over the private AWS network to the origin in us-west-2, which minimizes packet loss and improves performance without caching content. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of how AWS Global Accelerator differs from services like Amazon CloudFront—a common trap is confusing it with a CDN, but remember that Global Accelerator focuses on network path optimization rather than content caching. A helpful memory tip: think “Global Accelerator = faster network route, not cached content.”
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 has a web application deployed on AWS in the us-west-2 Region. The application is accessed by users across the globe, including Europe, Asia, and South America. The company wants to improve the application's performance for international users by reducing latency and packet loss. The solution must route user traffic over the AWS global network to the closest edge location. Which AWS service should the company use?

Correct answer & explanation
AWS Global Accelerator
AWS Global Accelerator is the correct choice because it uses the AWS global network to route user traffic to the closest edge location via Anycast IP addresses, reducing latency and packet loss. It optimizes the path from users to the application by directing traffic to the nearest edge endpoint, then forwarding it over the AWS backbone to the application in us-west-2. This improves performance for international users without caching content, unlike a CDN.
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 often confuse Amazon CloudFront's edge caching with Global Accelerator's network path optimization, assuming a CDN is always the best choice for reducing latency, but CloudFront does not improve the network path for non-cacheable traffic or dynamic API calls.
Trap categories for this question
Scenario analysis trap
Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations to improve delivery of static and dynamic web content. However, it is optimized for HTTP/HTTPS traffic and does not provide the same low-latency routing for non-HTTP protocols or for dynamic applications that cannot be cached. The scenario requires routing user traffic over the AWS global network to the closest edge location for any IP traffic, which is a capability of AWS Global Accelerator, not CloudFront.
Detailed technical explanation
How to think about this question
AWS Global Accelerator uses Anycast IP addresses, which allow multiple edge locations to advertise the same IP, so user traffic is automatically routed to the nearest edge location via BGP routing. From there, traffic enters the AWS global network and is forwarded to the application endpoint over the optimized, low-latency backbone, avoiding public internet congestion. This is particularly effective for protocols like TCP and UDP that benefit from consistent, low-latency paths, such as gaming, VoIP, or financial trading applications.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
