Allow CDP to create a VPC
You can choose to create a VPC through CDP.
If you choose to create a VPC through CDP, three subnets will be automatically created. One subnet is created for each availability zone assuming three AZs per region. If a region has two AZs instead of three, three subnets are still created, with two in the same AZ.
You will be asked to specify a valid CIDR in IPv4 range that will be used to define the range of private IPs for EC2 instances provisioned into these subnets.
