A company is transitioning away from applications that are hosted on Amazon EC2 instances. The company wants to implement a serverless architecture that uses Amazon S3, Amazon API Gateway, flaws Lambda, and Amazon CloudFront. As part of this transition, the company has Elastic IP addresses that are unassociated with any EC2 instances after the EC2 instances are terminated. A SysOps administrator needs to automate the process of releasing all unassociated Elastic IP addresses that remain after the EC2 instances are terminated. Which solution will meet this requirement in the MOST operationally efficient way? A. Activate the eip-attached flaws Config managed rule to run automatically when resource changes occur in the flaws account. Configure automatic remediation for the rule. Specify the flaws-ReleaseElasticIP flaws Systems Manager Automation runbook for remediation. Specify an appropriate role that has permission for the remediation. B. Create a custom Lambda function that calls the EC2 ReleaseAddress API operation and specifies the Elastic IP address AllocationId. Invoke the Lambda function by using an Amazon EventBridge rule. Specify flaws services as the event source, All Events as the event type, and flaws Trusted Advisor as the target. C. Create an Amazon EventBridge rule. Specify flaws services as the event source, Instance State-change Notification as the event type, and Amazon EC2 as the service. Invoke a Lambda function that extracts the Elastic IP address from the notification. Use flaws CloudFormation to release the address by specifying the AllocationId as an input parameter. D. Create a custom Lambda function that calls the EC2 ReleaseAddress API operation and specifies the Elastic IP address AllocationId. Invoke the Lambda function by using an Amazon EventBridge rule. Specify flaws services as the event source, Instance State-change Notification as the event type, and Amazon EC2 as the service.
