Question
A company uses Amazon Route 53 with latency-based routing across multiple AWS Regions to provide resiliency. The company uses Route 53 with latency-based routing to direct traffic to the nearest Region. Within each Region, weighted A records distribute traffic across multiple Availability Zones.
During a recent update, some Availability Zone endpoints became unhealthy. Route 53 continued to route traffic to the unhealthy endpoints. The company must prevent this issue from occurring in the future.
Which solution will meet this requirement?
- A. Add a Route 53 health check for each of the weighted records that received traffic during the recent update. Correct
- B. Increase the weight of Route 53 records in the Region where traffic must go during updates.
- C. Reconfigure all records to use latency-based routing across all Regions uniformly.
- D. Reduce the TTL value for latency-based routing to detect changes more quickly.
Explanation
According to AWS documentation, adding a Route 53 health check for each of the weighted records ensures that traffic is not routed to unhealthy endpoints. This solution directly addresses the issue by monitoring endpoint health and preventing traffic from being directed to unhealthy Availability Zone endpoints.
