- A
Amazon CloudFront
Why wrong: CloudFront caches content at edge locations — it reduces latency for cacheable content but doesn't improve routing performance for dynamic, non-cacheable traffic the same way Global Accelerator does.
- B
AWS Global Accelerator
Global Accelerator routes traffic into the AWS network at the nearest edge location, then uses AWS's congestion-free backbone to the endpoint — improving performance for TCP/UDP applications beyond what CloudFront provides.
- C
Amazon Route 53 with latency routing
Why wrong: Route 53 latency routing directs DNS to the nearest Region but traffic still routes over the public internet — Global Accelerator keeps traffic on the AWS backbone after the first hop.
- D
Amazon VPC peering
Why wrong: VPC peering connects VPCs within or between Regions — it doesn't improve global user-to-application routing performance.
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 wants to deploy their application globally and needs AWS to automatically route users to the nearest healthy application endpoint with improved network performance. Which AWS service uses the AWS global network backbone for routing optimization?
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
AWS Global Accelerator
AWS Global Accelerator uses the AWS global network backbone to optimize the path from users to applications. It routes traffic over the AWS internal network rather than the public internet, improving performance and reliability. It also automatically directs users to the nearest healthy endpoint, meeting the requirement for global deployment with automatic failover.
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.
- ✗
Amazon CloudFront
Why it's wrong here
CloudFront caches content at edge locations — it reduces latency for cacheable content but doesn't improve routing performance for dynamic, non-cacheable traffic the same way Global Accelerator does.
- ✓
AWS Global Accelerator
Why this is correct
Global Accelerator routes traffic into the AWS network at the nearest edge location, then uses AWS's congestion-free backbone to the endpoint — improving performance for TCP/UDP applications beyond what CloudFront provides.

Why it's wrong here

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-layer routing, but CloudFront is for content delivery and does not optimize TCP/UDP traffic routing to application endpoints using the AWS global backbone.
Detailed technical explanation
How to think about this question
AWS Global Accelerator works by providing two static anycast IP addresses that serve as fixed entry points. Traffic enters at the nearest edge location via the AWS global network, then is forwarded over the AWS backbone to the optimal regional endpoint (e.g., Application Load Balancer, Network Load Balancer, or EC2 instance). It uses TCP and UDP termination at the edge and maintains persistent connections, which reduces jitter and improves performance for latency-sensitive applications like gaming or VoIP.
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.
