A company runs a high-performance web service deployed across two AWS Regions: us-east-1 and eu-west-1. The company wants to route users to the closest Region to minimize latency, but must automatically stop routing traffic to a Region if its endpoint fails. The solutions architect needs to configure Amazon Route 53 to meet these requirements.
Which combination of Route 53 configurations should the solutions architect implement? (Select TWO.)
- Create latency-based routing records in Route 53 that point to the endpoints in each Region.Answer
- Associate a Route 53 health check with each latency record to monitor endpoint availability.Answer
- CCreate failover routing records in Route 53 and set one Region as primary and the other as secondary.
- DConfigure geolocation routing records to automatically route based on the lowest network latency.
- EConfigure Amazon RDS read replicas in the secondary Region to automatically update the DNS records during a failover event.
Answer
To achieve low latency and high availability, create latency-based routing records in Route 53 for both Regions and associate each record with a Route 53 health check.
To route users to the closest Region to minimize latency, latency-based routing must be used. To ensure that traffic is not routed to an unhealthy Region, Route 53 health checks must be associated with the routing records so that Route 53 can automatically perform DNS failover when an endpoint becomes unhealthy.
