You lead a team to use Kubernetes to develop some microservices in the local server and data center. To align with the company’s strategy to move to the AWS cloud, you need to consider the possibilities of migrating the projects that your team is working on. You think that Amazon Elastic Container Service for Kubernetes (Amazon EKS) is a good candidate. In order to start using EKS properly, which prerequisites must be met? (Select TWO)

Answer options:

A.All related container images are registered in Amazon ECR since EKS can only pull docker images from ECR.
B.A Route53 should be in place for Amazon EKS to route internet traffic among various public subnets.
C.An IAM EKS service role should be created to allow Amazon EKS to manage clusters on your behalf.
D.A VPC exists for the EKS cluster to use. 

Correct Answer – C, D
In order to use the EKS service properly, some prerequisites must be met, which is mentioned in https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html.
Option A is incorrect because EKS can pull Docker images from ECR or any other container registries, such as Docker Hub.
Option B is incorrect because using Route53 alone will not help to access the cluster. In addition to standard Amazon EKS permissions, your IAM user or role must have route53:AssociateVPCWithHostedZone permissions to enable the cluster`s endpoint private access.

Option C is correct because Amazon EKS needs the IAM role to create AWS resources such as a load balancer.
Option D is correct because EKS has also provided a CloudFormation template to provide a suitable VPC for the EKS cluster. The link https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html contains the instructions on how to create the cluster VPC for EKS.
