Exam AWS Certified SysOps Administrator - Associate topic 1 question 190 discussion

Exam question from Amazon's AWS Certified SysOps Administrator - Associate
Question #: 190
Topic #: 1
[All AWS Certified SysOps Administrator - Associate Questions]

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?

  • 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.

I'd say "latency routing" is the only solution to for "users from all over the world access the application" to have "fastest response times". If the users were limited to the three specified regions, then the answer might be A.

Option B was also pretty close interms of transitioning over to the Latency routing selection IMO but the reason why I didn't pick it up was because it didnt' specifically mention about the solution on the missing "ap-south-1" region. That missing gap in the statement leans me towards the option D.

Does Elastic load balancer work across regions? Amazon has made the creation and management of load balancers in the cloud a lot simpler when they created elastic load balancers. But elastic load balancers have one fatal flaw. They exist within a single AWS region and if that region is having an outage, then your whole application goes down.

latency routing + ELB on one region seems clue.

Correct is D. The fastest response time so latency based routing has to be used.
