ANS-C01 Network Design Practice Question
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?
⚠ Common exam trap
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.
Answer choices
Why each option matters
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.
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.
