The answer is latency-based routing with health checks. This combination is correct because latency-based routing directs traffic to the region that provides the lowest latency for each user, while health checks continuously monitor endpoint health and automatically remove unhealthy regions from the routing pool, ensuring failover to the next lowest-latency healthy region. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how to combine routing policies for global application resilience—a common trap is confusing latency routing with geoproximity, which uses geographic distance rather than actual network performance. Remember that latency routing alone cannot failover; you must pair it with health checks to achieve both performance optimization and fault tolerance. A useful memory tip: think "lowest ping, healthy ring" to recall that traffic goes to the fastest responding region that passes its health check.
ANS-C01 Network Design Practice Question
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 has a global application that uses Amazon Route 53 for DNS. The application is deployed in us-east-1 and eu-west-1. The company wants to route users to the Region with the lowest latency, but also provide failover if one Region becomes unhealthy. Which Route 53 routing policy should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Latency-based routing with health checks
Option D is correct because latency-based routing with health checks automatically routes to the lowest latency region that is healthy. Option A is wrong because geoproximity routing uses location, not latency. Option B is wrong because failover routing does not consider latency. Option C is wrong because weighted routing does not consider latency or health.
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.
✗
Weighted routing with equal weights
Why it's wrong here
Weighted routing distributes load but does not consider latency or health.
✗
Failover routing with primary in us-east-1
Why it's wrong here
Failover does not route to lowest latency; it uses primary/secondary.
✓
Latency-based routing with health checks
Why this is correct
Latency routing sends to lowest latency region; health checks ensure failover.

✗
Geoproximity routing
Why it's wrong here
Geoproximity routes based on geographic location, not live latency.
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 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.
