Topic 1 Question 367
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?
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.
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.
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.
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.

AWS Global Accelerator is a service that helps to improve the availability and performance of applications by directing traffic through the AWS global network. It automatically routes traffic to the closest AWS Region based on the lowest latency for the end user.
By creating an endpoint group for each AWS Region, the Global Accelerator can distribute traffic across multiple Regions. This means that users will be routed to the Region with the lowest latency, ensuring the best performance for their location.
Adding a listener to the accelerator allows it to listen for incoming traffic and direct it to the appropriate endpoint group.
The AWS Global Accelerator constantly monitors the health of the endpoints (applications) in each endpoint group. If an endpoint becomes unhealthy or experiences a failure, the Global Accelerator automatically reroutes traffic to a healthy instance of the application in another Region, ensuring high availability and automatic failover.

Global accelerator cannot satisfy the lowest latency requirement. only latency based routing policy can. it can max out performance but in the documentation the wording does not state latency. it covers many different factors but latency isn't one of them.
The wording in the question to me doesn't scream out failover. they are asking if traffic will be re routed to another healthy instance in the event of the lowest latency instance failing. still using the lowest latency policy it will hit the other instance in the ALB target group.
This is a tricky one but I cant see past the "has to route based on latency"
