A company uses AWS Cost Explorer to monitor AWS costs. The company notices that Amazon Elastic Block Store (Amazon EBS) storage and snapshot costs increase every month, but it does not provision additional EBS storage. The company wants to optimize monthly costs for current storage usage with the LEAST operational overhead. Which solution meets these requirements?

The correct answer addresses both increasing snapshot and storage costs with minimal operational overhead. Deleting nonessential snapshots directly reduces current snapshot costs. Implementing Amazon Data Lifecycle Manager (DLM) automates the creation, retention, and deletion of snapshots based on defined policies. This prevents future accumulation of unneeded snapshots, thereby controlling costs proactively without manual intervention. Incorrect options: Monitoring EBS storage utilization with CloudWatch Logs or a custom script and then using Elastic Volumes to reduce size doesn't address snapshot costs, which are a significant part of the problem. Also, reducing volume size might not always be feasible or necessary if the issue is snapshot sprawl. Deleting all expired and unused snapshots is a good partial step, but it doesn't provide a long-term, automated solution for managing future snapshots, leading to recurring cost issues.
