Your firm manages IP address distribution via the use of an IP Address Management (IPAM) tool. The IPAM makes an API available. CloudFormation is used by development teams to provide authorized reference architectures. IP addresses must be assigned to the VPC during deployment. When a virtual private cloud is destroyed, the IPAM must recover the virtual private cloud's IP allocation.

Which approach enables the IPAM to be integrated with CloudFormation in an effective and automated manner?

A. AWS CloudFormation parameters using the ג€Ref::ג€ intrinsic function
B. AWS CloudFormation custom resource using an AWS Lambda invocation. Most Voted
C. CloudFormation::OpsWorks::Stack with custom Chef configuration.
D. AWS CloudFormation parameters using the ג€Fn::FindInMapג€ intrinsic function.
