Which Network Types are Assigned Private IP Addresses in CloudFormation Automation?

When automating the creation of a network using CloudFormation, it is common to assign a private IP address to a subnet, which is represented by an AWS::EC2::Subnet resource type. Therefore, the correct answer is A. AWS::EC2::Subnet.

A subnet is a range of IP addresses in a VPC that can be used to isolate compute resources. When you create a subnet, you specify a range of IP addresses within the VPC CIDR block. This range of IP addresses can be used by the instances in the subnet.

In a VPC, you can assign both private and public IP addresses to instances. Private IP addresses are used for internal communication within the VPC, while public IP addresses are used for external communication over the internet.

When you create a subnet, you can specify whether it is a public or private subnet. Public subnets have a route to an internet gateway, which allows instances in the subnet to communicate with the internet using a public IP address. Private subnets do not have a route to the internet gateway, so instances in the subnet can only communicate with other instances in the VPC using private IP addresses.

In CloudFormation, you can create a subnet using the AWS::EC2::Subnet resource type. When creating a subnet, you can specify the VPC that the subnet belongs to, the availability zone where the subnet is located, and the range of IP addresses that are assigned to the subnet.

To assign a private IP address to a subnet, you can specify a range of IP addresses within the VPC CIDR block that is not used by the internet gateway. This allows instances in the subnet to communicate with other instances in the VPC using private IP addresses.

In summary, when automating the creation of a network using CloudFormation, it is common to assign a private IP address to a subnet using the AWS::EC2::Subnet resource type.
