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 architecture for disaster recovery. They need to use Route 53 to route traffic to the nearest healthy endpoint. Which routing policy should they use?
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
Latency-based routing with health checks is the correct choice because it directs traffic to the endpoint with the lowest latency for the user, while health checks ensure that traffic is only sent to healthy endpoints. This combination meets the requirement to route to the nearest healthy endpoint in a multi-region disaster recovery setup, as it dynamically adapts to both network conditions and endpoint availability.
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.
✗
Failover routing
Why it's wrong here
Failover routing sends all traffic to primary unless primary is unhealthy, then to secondary. It does not consider latency.
✗
Geolocation routing
Why it's wrong here
Geolocation routes based on user location but does not consider health of endpoints by default.
✗
Latency-based routing without health checks
Why it's wrong here
Without health checks, traffic may be sent to unhealthy endpoints.
✓
Latency-based routing with health checks
Why this is correct
Latency-based routing directs to the region with lowest latency, and health checks ensure only healthy endpoints receive traffic.

Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the misconception that latency-based routing inherently considers endpoint health, but without explicit health checks, it will route to an unhealthy endpoint if it has the lowest latency, making health checks mandatory for the 'nearest healthy endpoint' requirement.
Detailed technical explanation
How to think about this question
Latency-based routing uses a global network of Route 53 latency measurement servers to determine the endpoint with the lowest round-trip time for each user. Health checks, which can be configured to monitor endpoint status via HTTP, HTTPS, or TCP, are integrated with latency records to automatically exclude unhealthy endpoints from routing decisions, ensuring traffic is only directed to available resources. In a disaster recovery scenario, this allows seamless failover to a secondary region if the primary region becomes unhealthy, while still optimizing for latency.

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.
