Question 487 of 1,705
Multi-Region Active-Active with Route 53 Latency-Based Routing
This ANS-C01 practice question tests your understanding of network implementation. 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 implementing a multi-region active-active application. They want to route users to the nearest healthy endpoint using DNS. Which AWS service should be used?

Correct answer & explanation
✓
Amazon Route 53 latency-based routing
Amazon Route 53 latency-based routing directs traffic based on the lowest network latency between the user and the endpoint, making it ideal for routing users to the nearest healthy endpoint in a multi-region active-active setup. It continuously monitors endpoint health via health checks and only routes to healthy endpoints, ensuring high availability and performance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Uses Anycast, not DNS latency routing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse AWS Global Accelerator (which also routes to the nearest healthy endpoint) with DNS-based routing, but Global Accelerator uses Anycast at the network layer, not DNS, so it does not meet the 'using DNS' requirement specified in the question.
Detailed technical explanation
How to think about this question
Route 53 latency-based routing uses a global latency database built from continuous measurements between AWS edge locations and endpoints; when a DNS query arrives, Route 53 returns the IP of the endpoint with the lowest latency for that user's location. Health checks are performed every 30 seconds by default, and if an endpoint fails, Route 53 automatically removes it from the routing pool, preventing traffic to unhealthy resources. This service is defined in the Route 53 documentation as a 'latency routing policy' and is distinct from geolocation routing, which uses static geographic mappings.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
