You are developing an application that will store and access sensitive unstructured data objects in a Cloud Storage bucket. To comply with regulatory requirements, you need to ensure that all data objects are available for at least 7 years after their initial creation. Objects created more than 3 years ago are accessed very infrequently (less than once a year). You need to configure object storage while ensuring that storage cost is optimized. What should you do? (Choose two.)

A. Set a retention policy on the bucket with a period of 7 years. B. Use IAM Conditions to provide access to objects 7 years after the object creation date. C. Enable Object Versioning to prevent objects from being accidentally deleted for 7 years after object creation. D. Create an object lifecycle policy on the bucket that moves objects from Standard Storage to Archive Storage after 3 years. E. Implement a Cloud Function that checks the age of each object in the bucket and moves the objects older than 3 years to a second bucket with the Archive Storage class. Use Cloud Scheduler to trigger the Cloud Function on a daily schedule.
