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 active-active architecture with an Application Load Balancer in each region. Which service can route traffic to the closest ALB based on latency?
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 latency-based routing
Amazon Route 53 latency-based routing directs traffic to the AWS region that provides the lowest latency for the end user, based on historical latency measurements between the user's ISP and each region. This makes it the correct choice for routing users to the closest Application Load Balancer in a multi-region active-active architecture.
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 not latency-based per request.
✓
Amazon Route 53 latency-based routing
Why this is correct
Route 53 latency routing directs users to the region with lowest latency.
Related concept
Read the scenario before looking for a memorised answer.
Cross-zone balancing is within a region, not for multi-region routing.
✗
Amazon CloudFront
Why it's wrong here
CloudFront is a CDN, not a load balancer for dynamic content routing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Global Accelerator's 'nearest endpoint' behavior with latency-based routing, but Global Accelerator uses Anycast to direct traffic to the closest edge location, not to the region with the lowest application latency, making Route 53 latency-based routing the correct answer for this specific use case.
Detailed technical explanation
How to think about this question
Route 53 latency-based routing works by maintaining a latency map built from probe data between AWS edge locations and end-user ISPs. When a DNS query arrives, Route 53 evaluates the latency records for the same name in different regions and returns the IP of the resource in the region with the lowest estimated latency. This routing is performed at DNS resolution time, so subsequent requests from the same client may be routed differently if latency profiles change, and it requires health checks to avoid routing to unhealthy ALBs.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
