QuestionQ24

Reliability and Business Continuity

A company uses Amazon Route 53 latency-based routing across multiple AWS Regions to provide resiliency. Route 53 latency-based routing directs traffic to the nearest Region. Within every Region, weighted A records distribute traffic across multiple Availability Zones.

During a recent update, some Availability Zone endpoints became unhealthy, but Route 53 continued routing traffic to those unhealthy endpoints. The company must prevent this issue in the future.

Which solution meets this requirement?

Explanation

Route 53 health checks can be associated with weighted records so that unhealthy endpoint records are not returned in DNS responses. This allows traffic to be directed only to healthy Availability Zone endpoints while retaining the existing latency-based regional routing and weighted distribution.
