DOP-C02 Resilient Cloud Solutions Practice Question
A DevOps engineer is designing a highly available web application using Amazon Route 53. The application is deployed in two AWS Regions. The engineer wants to route traffic to the nearest healthy endpoint. Which routing policy should be used?
⚠ Common exam trap
DOP-C02 often tests the distinction between latency and geolocation routing; candidates may incorrectly choose geolocation because they equate 'nearest' with geographic proximity, but latency routing is specifically for lowest network latency.

Correct answer & explanation
✓
Latency routing
Latency routing in Amazon Route 53 directs users to the AWS Region that provides the lowest network latency, which matches the requirement to route traffic to the nearest healthy endpoint. Route 53 uses latency measurements between the user and each AWS Region to select the optimal record. Health checks can be associated with latency records to ensure traffic only goes to healthy endpoints.
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 traffic to a secondary endpoint only when the primary health check fails, so all users reach one Region while it is healthy. It suits active-passive disaster recovery, not directing each user to the nearest healthy endpoint.
- ✗
Weighted routing
Why it's wrong here
Weighted routing distributes traffic by assigned proportions regardless of endpoint health or user location, so it cannot select the nearest healthy Region. It suits gradual releases or A/B splits, whereas proximity to users with health awareness requires latency-based routing.
- ✗
Geolocation routing
Why it's wrong here
Geolocation routing maps users to endpoints by their geographic origin, which approximates but does not measure actual network latency, and it ignores health unless records are health-checked. It suits content localisation or data-residency rules, not nearest-endpoint selection.
- ✓
Latency routing
Why this is correct
Latency routing directs users to the Region with the lowest measured latency, satisfying the nearest-healthy-endpoint requirement. Route 53 latency records support health checks, so unhealthy endpoints are excluded automatically. Unlike geolocation, which maps users by geography, latency uses actual network performance between resolver and endpoint.
