AWS Certified SysOps Administrator – Associate — Question 108
A company has a simple web application that runs on a set of Amazon EC2 instances behind an Elastic Load Balancer in the eu-west-2 Region. Amazon Route 53 holds a DNS record for the application with a simple routing policy. Users from all over the world access the application through their web browsers.
The company needs to create additional copies of the application in the us-east-1 Region and in the ap-south-1 Region. The company must direct users to the Region that provides the fastest response times when the users load the application.
What should a SysOps administrator do to meet these requirements?
Answer options
- A. In each new Region, create a new Elastic Load Balancer and a new set of EC2 instances to run a copy of the application. Transition to a geolocation routing policy.
- B. In each new Region, create a copy of the application on new EC2 instances. Add these new EC2 instances to the Elastic Load Balancer in eu-west-2. Transition to a latency routing policy.
- C. In each new Region, create a copy of the application on new EC2 instances. Add these new EC2 instances to the Elastic Load Balancer in eu-west-2. Transition to a multivalue routing policy.
- D. In each new Region, create a new Elastic Load Balancer and a new set of EC2 instances to run a copy of the application. Transition to a latency routing policy.
Correct answer: D
Explanation
The correct answer is D because creating a new Elastic Load Balancer and EC2 instances in each Region allows for optimal resource distribution and responsiveness. Additionally, transitioning to a latency routing policy ensures users are directed to the Region with the lowest latency. Options A, B, and C do not adequately address the requirement for latency-based routing or involve unnecessary complexity by not creating independent load balancers.
