Explanation:
AWS Global Accelerator provides the shortest failover time because it uses static IP addresses and anycast routing, bypassing the reliance on DNS TTLs and client-side DNS caching. It also continuously monitors endpoint health and automatically routes user traffic to the closest healthy endpoint based on performance and latency, fulfilling all requirements perfectly.
Ultimate access to all questions.
A SysOps administrator needs to deploy an application in multiple AWS Regions. The SysOps administrator must implement a solution that routes users to the Region with the lowest latency. In case of failure, the solution must automatically route requests to a Region with a healthy instance of the application. The company needs a solution with the shortest time to failover. Which solution will meet these requirements?
A
Create Amazon Route 53 records that have the same name for each endpoint. Use a latency routing policy. Associate a health check with each record.
B
Create Amazon Route 53 records that have the same name for each endpoint. Use a failover routing policy. Associate a health check with each record.
C
Create an AWS Global Accelerator standard accelerator. Create an endpoint group for each Region. Add a listener to the accelerator. Associate the endpoint group with the listener.
D
Create Amazon Route 53 records that have the same name for each endpoint. Use a geolocation routing policy. Associate a health check with each record.
