A company runs a web application in a single AWS Region. A solutions architect wants to ensure that the web application can continue to operate if the application becomes unavailable in the Region.
Which solution will meet this requirement?
A.
Deploy the application in multiple Regions. Use Amazon Route 53 DNS health checks to route traffic to a healthy Region.
B.
Deploy the application in multiple Availability Zones within a single Region. Use Amazon Route 53 DNS health checks to route traffic to healthy application resources.
C.
Deploy the application in multiple Regions. Use an Amazon Route 53 simple routing record to route traffic to a healthy Region.
D.
Deploy the application in multiple Availability Zones within a single Region. Use an Amazon Route 53 latency record in each Availability Zone to route traffic to a healthy Availability Zone.
To protect against a Regional failure, the application must be deployed in multiple Regions. Amazon Route 53 DNS failover with health checks allows traffic to be automatically routed to a healthy Region when the primary becomes unavailable, meeting high availability and disaster recovery requirements.
