ANS-C01 Network Design Practice Question
A company is designing a highly available network for a critical application that requires sub-second failover between two AWS regions. The application uses active-active traffic distribution. Which routing policy should they use in Amazon Route 53?
⚠ Common exam trap
The ANS-C01 exam often tests the misconception that Failover routing is the only way to achieve high availability, but the trap here is that the question specifies active-active traffic distribution, which requires a routing policy that supports multiple healthy endpoints simultaneously, not a primary/standby model.

Correct answer & explanation
✓
Latency routing with health checks
Latency routing with health checks is the correct choice because it directs traffic to the region that provides the lowest latency for each user, and when combined with health checks, Route 53 can automatically route traffic away from unhealthy endpoints. This enables sub-second failover between two active-active regions, as Route 53's DNS-based health checking and routing updates occur quickly (typically within a few seconds) without requiring manual intervention or a primary/secondary failover model.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Latency routing with health checks
Why this is correct
Correct: Distributes traffic based on latency and health.
- ✗
Failover routing
Why it's wrong here
Wrong: Active-passive, not active-active.
- ✗
Geolocation routing
Why it's wrong here
Wrong: Based on location, not performance or failover.
- ✗
Weighted routing
Why it's wrong here
Wrong: No health check integration for failover.
