Amazon Web Services SAA-C03 Question Answer

A company deployed an application in two AWS Regions. If the application becomes unavailable in one Region, the application must fail over to the second Region. The failover process must avoid stale DNS client caches. The company wants to use one endpoint to access both copies of the application.

Which solution will meet these requirements?

Use an Amazon CloudFront distribution that has multiple origins. Correlate each origin with the application in each Region.

Use an Amazon Route 53 weighted routing policy that uses equal weights to route client requests to the second Region if the application becomes unavailable in the original Region.

Use AWS Global Accelerator, and assign a static anycast IP address to the application endpoint.

Use an Amazon Route 53 IP-based routing policy to route requests to the second Region if the application becomes unavailable in the original Region.
