As a Google Associate Cloud Engineer, you are tasked with managing the lifecycle of video files stored in a Cloud Storage Regional bucket. Your objective is to optimize storage costs by implementing a lifecycle policy that transitions these video files to a more cost-effective storage class and eventually deletes them. Specifically, you need to configure a policy that automatically moves videos to Coldline storage after 90 days and deletes them one year after their creation date. How should you configure this lifecycle policy to achieve the desired outcome?
