Question #: 54
Topic #: 6

A company has a website that serves many visitors. The company deploys a backend service for the website in a primary AWS Region and a disaster recovery (DR) Region.

A single Amazon CloudFront distribution is deployed for the website. The company creates an Amazon Route 53 record set with health checks and a failover routing policy for the primary Region ' s backend service. The company configures the Route 53 record set as an origin for the CloudFront distribution. The company configures another record set that points to the backend service ' s endpoint in the DR Region as a secondary failover record type. The TTL for both record sets is 60 seconds.

Currently, failover takes more than 1 minute. A solutions architect must design a solution that will provide the fastest failover time.

Which solution will achieve this goal?


A.

Deploy an additional CloudFront distribution. Create a new Route 53 failover record set with health checks for both CloudFront distributions.


B.

Set the TTL to 1 second for the existing Route 53 record sets that are used for the backend service in each Region.


C.

Create new record sets for the backend services by using a latency routing policy. Use the record sets as an origin in the CloudFront distribution.


D.

Create a CloudFront origin group that includes two origins, one for each backend service Region. Configure origin failover as a cache behavior for the CloudFront distribution.
