A company uses AWS Organizations and tags resources by account. The company also uses AWS Backup to back up its AWS resources. The company needs to ensure all AWS resources are backed up with the LEAST operational overhead. Which solution meets this requirement?

The correct solution leverages AWS Config to identify untagged resources, which is crucial because AWS Backup plans can use tags to define backup scope. By programmatically tagging these resources, the company can then include them in a centralized backup plan based on tags, minimizing manual effort and ensuring comprehensive coverage with the least operational overhead. Incorrect options: Identifying non-running resources and adding them to a backup vault is not a comprehensive backup strategy and doesn't address the core requirement of backing up all resources efficiently. Requiring manual review by account owners is prone to human error, inconsistent, and creates significant operational overhead, directly contradicting the requirement. Amazon Inspector is for security vulnerability assessment, not for identifying resources for backup or managing backup compliance.
