This ANS-C01 practice question tests your understanding of network design. 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 is designing a multi-region application with an Application Load Balancer (ALB) in us-east-1 and us-west-2. They want to route traffic to the nearest region using latency-based routing. Which AWS service should they use to achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon Route 53 with latency routing policy
Amazon Route 53 latency-based routing directs traffic to the region with the lowest latency for the end user. AWS Global Accelerator provides static IP and traffic management but not latency-based routing to specific load balancers in multiple regions. CloudFront is a CDN, not for routing to ALBs. Direct Connect is for dedicated network connections. Transit Gateway is for VPC connectivity.
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.
✗
AWS Global Accelerator
Why it's wrong here
Global Accelerator uses anycast IPs to route to the nearest endpoint, but it does not provide latency-based routing policies like Route 53.
✗
AWS Transit Gateway
Why it's wrong here
Transit Gateway is used for network connectivity between VPCs, not for DNS-based routing.
✗
Amazon CloudFront with multiple origins
Why it's wrong here
CloudFront is a content delivery network, not designed for latency-based routing to ALBs in a multi-region active-active setup.
✓
Amazon Route 53 with latency routing policy
Why this is correct
Route 53 latency-based routing directs traffic to the region with the lowest latency for the user, perfect for multi-region ALBs.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
