Explanation:
AWS Global Accelerator is designed for low-latency routing and fast failover. While Route 53 latency routing (Option A) can route based on latency, failover depends on DNS TTL, which can lead to delays in redirecting traffic if a cached record exists. Global Accelerator uses the AWS global network to route traffic to the optimal regional endpoint and provides near-instant failover (typically within seconds) by directing traffic to healthy endpoints automatically.

Question 17. 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 A 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 A 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 A records that have the same name for each endpoint. Use a geolocation routing policy. Associate a health check with each record.
E
None
F
