- A
AWS Global Accelerator
Correct. AWS Global Accelerator provides static IP addresses and optimizes the path from users to applications over TCP/UDP, routing traffic to the nearest healthy endpoint using the AWS global network.
- B
Amazon CloudFront
Why wrong: Incorrect. Amazon CloudFront is a CDN that caches and delivers content over HTTP/HTTPS only. It does not support UDP traffic and does not provide static IP addresses for application endpoints.
- C
Amazon Route 53
Why wrong: Incorrect. Amazon Route 53 is a DNS service that translates domain names to IP addresses but does not provide static IP addresses. DNS responses can change based on routing policies, and Route 53 alone does not optimize network paths for UDP traffic.
- D
AWS Direct Connect
Why wrong: Incorrect. AWS Direct Connect is a dedicated private connection between on-premises data centers and AWS, used for hybrid architectures. It does not provide global traffic routing with static IPs for internet-facing applications.
Quick Answer
The answer is AWS Global Accelerator. This service is the correct choice because it provides static IP addresses that act as fixed entry points for whitelisting by internet service providers, while using the AWS global network and Anycast routing to direct UDP and TCP traffic to the nearest healthy application endpoint, minimizing latency for real-time gaming. On the AWS Certified Cloud Practitioner CLF-C02 exam, this scenario tests your understanding of how Global Accelerator differs from CloudFront—CloudFront handles HTTP/HTTPS and dynamic content caching, whereas Global Accelerator excels at non-HTTP protocols like UDP and requires static IPs for global routing. A common trap is choosing CloudFront for low latency, but remember: if the question mentions UDP or static IPs for ISP whitelisting, Global Accelerator is the only answer. Memory tip: "Global Accelerator gives you a fixed front door for any protocol, anywhere."
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 globally distributed multiplayer game on AWS. The game uses UDP for real-time communication and requires static IP addresses that do not change for whitelisting by internet service providers. The company needs to route traffic to the nearest healthy application endpoint to minimize latency and improve performance. The solution must work with both TCP and UDP traffic and provide static IP addresses. Which AWS service should the company use?

Correct answer & explanation
AWS Global Accelerator
AWS Global Accelerator provides static IP addresses that serve as fixed entry points to your application, and it uses the AWS global network to route traffic to the nearest healthy endpoint via Anycast. It supports both TCP and UDP traffic, making it ideal for real-time UDP-based gaming workloads that require low latency and static IPs for ISP whitelisting.
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 CloudFront's edge caching with Global Accelerator's network-layer optimization, but CloudFront does not support UDP or provide static IPs, making it unsuitable for real-time gaming traffic.
Detailed technical explanation
How to think about this question
AWS Global Accelerator uses Anycast IP addresses that are announced from multiple AWS edge locations, so traffic automatically routes to the nearest edge location and then over the AWS global backbone to the optimal application endpoint. It integrates with Network Load Balancers, Application Load Balancers, and EC2 instances, and can perform health checks to route traffic only to healthy endpoints. For UDP-based games, this ensures low-latency, jitter-controlled paths without the overhead of DNS resolution or protocol conversion.
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.
