Topic #: 18

A DevOps engineer is writing an AWS CloudFormation template to stand up a web service that will run on Amazon EC2 instances in a private subnet behind an ELB Application Load Balancer. The Engineer must ensure that the service can accept requests from clients that have IPv6 addresses. Which configuration items should the Engineer incorporate into the CloudFormation template to allow IPv6 clients to access the web service?

AAssociate an IPv6 CIDR block with the Amazon VPC and subnets where the EC2 instances will live. Create route table entries for the IPv6 network, use EC2 instance types that support IPv6, and assign IPv6 addresses to each EC2 instance.

BReplace the Application Load Balancer with a Network Load Balancer. Associate an IPv6 CIDR block with the Virtual Private Cloud (VPC) and subnets where the Network Load Balancer lives, and assign the Network Load Balancer an IPv6 Elastic IP address.

CAssign each EC2 instance an IPv6 Elastic IP address. Create a target group and add the EC2 instances as targets. Create a listener on port 443 of the Application Load Balancer, and associate the newly created target group as the default target group.

DCreate a target group and add the EC2 instances as targets. Create a listener on port 443 of the Application Load Balancer. Associate the newly created target group as the default target group.

This question seems pretty tricky. I'm not sure if I fully understand the requirements, but it sounds like we need to find a way to restrict IAM user creation unless the user is on an exception list.
