- A
Amazon CloudFront with the Application Load Balancer configured as a custom origin
Why wrong: Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations to reduce latency. It does not provide static anycast IP addresses for forwarding TCP/UDP traffic directly to an origin; instead it uses a domain name and regional edge caches. CloudFront is optimized for delivering cacheable content (e.g., images, videos, APIs), not for providing fixed IP endpoints for application-level traffic routing based on health.
- B
AWS Global Accelerator with the Application Load Balancer configured as an endpoint
AWS Global Accelerator provides two static anycast IP addresses that act as a fixed entry point. It uses the AWS global network to route traffic over UDP and TCP to the nearest healthy endpoint (e.g., an Application Load Balancer). This improves performance by reducing internet latency and provides automatic failover. The solution meets all the requirements: static IPs, global network routing, and health-based routing.
- C
Amazon Route 53 with latency-based routing policy
Why wrong: Amazon Route 53 with latency-based routing uses DNS to route users to the endpoint with the lowest latency. However, DNS relies on resolver caches and does not provide static anycast IP addresses. The IP addresses returned by Route 53 are the actual endpoint IPs, which can change and are not anycast. This approach also does not provide the same level of TCP/UDP traffic optimization as AWS Global Accelerator.
- D
Amazon S3 Transfer Acceleration
Why wrong: Amazon S3 Transfer Acceleration is a service that speeds up uploads to Amazon S3 by using AWS edge locations. It is not designed to route general application traffic to compute endpoints like an Application Load Balancer, nor does it provide static anycast IP addresses for the application itself. It is specific to S3 uploads only.
Quick Answer
The answer is AWS Global Accelerator, which provides two static anycast IP addresses that remain fixed over time and automatically route incoming traffic to the nearest healthy endpoint via the AWS global network. This works because Global Accelerator uses anycast addressing, where the same IP address is advertised from multiple AWS edge locations, so user traffic is directed to the closest healthy Application Load Balancer endpoint in us-east-1, reducing latency and improving availability. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of how Global Accelerator differs from services like CloudFront or Route 53—CloudFront is for content caching, not static IPs, and Route 53 uses DNS-based routing, which can change IPs. A common trap is confusing Global Accelerator’s fixed anycast IPs with CloudFront’s dynamic IPs or Route 53’s DNS resolution. Remember the memory tip: “Anycast IPs stay put, Global Accelerator takes the shortest route.”
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 hosts a web application on an Application Load Balancer in the us-east-1 AWS Region. Users are distributed across North America, Europe, and Asia. The company wants to improve application performance and availability for global users by using the AWS global network. The solution must provide two static anycast IP addresses that do not change over time and automatically route incoming traffic to the nearest healthy endpoint in the region. Which AWS service should the company use?

Correct answer & explanation
AWS Global Accelerator with the Application Load Balancer configured as an endpoint
AWS Global Accelerator provides two static anycast IP addresses that serve as fixed entry points to the application. It uses the AWS global network to route traffic to the nearest healthy Application Load Balancer endpoint in us-east-1, automatically rerouting in case of endpoint failure. This meets the requirement for static IPs and performance improvement via the AWS backbone.
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 confusing CloudFront's edge caching with Global Accelerator's static IP and anycast routing; candidates often pick CloudFront because it also improves performance, but it does not provide fixed anycast IP addresses that remain unchanged over time.
Detailed technical explanation
How to think about this question
AWS Global Accelerator leverages the AWS global network and edge locations to terminate TCP/UDP connections at the edge, then routes traffic over the AWS backbone to the optimal regional endpoint. It uses Anycast IP addresses from AWS's pool, which are announced from multiple edge locations simultaneously, ensuring traffic goes to the nearest healthy endpoint. This is distinct from CloudFront, which uses DNS-based routing and can change IPs, and from Route 53, which operates at the DNS level and is subject to caching delays.
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.
