ANS-C01 Network Design Practice Question
A company wants to design a multi-region active-active architecture with Amazon Route 53 latency-based routing and failover using health checks. Which TWO configurations are necessary? (Choose two.)
⚠ Common exam trap
Candidates often confuse latency-based routing with geolocation routing, or incorrectly assume that a failover record type must be explicitly set to 'Active-Active', when in fact the active-active behavior is achieved by combining latency-based routing with health checks, not by a specific record type.
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
✓
Configure a latency alias record for each region's resource
Latency-based routing in Route 53 uses alias records to route traffic based on the lowest latency for the end user. Configuring a latency alias record for each regional resource (e.g., an Application Load Balancer) allows Route 53 to respond with the IP of the resource that provides the best latency. Option D is correct because health checks must be associated with each latency record to enable failover; if a resource fails its health check, Route 53 removes it from the pool of healthy endpoints, ensuring traffic is only routed to healthy regions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use geolocation routing to direct users to the nearest region
Why it's wrong here
Geolocation routing is different from latency routing.
- ✗
Assign a weight to each record for traffic distribution
Why it's wrong here
Weights are used in weighted routing, not latency routing.
- ✓
Configure a latency alias record for each region's resource
Why this is correct
Latency-based routing uses latency alias records.
- ✓
Create a health check for each resource and associate it with the record
Why this is correct
Health checks are required for failover.
- ✗
Set the failover record type to 'Active-Active'
Why it's wrong here
Failover routing records support only active-passive.
