Your subscription includes a storage account named storage1. How can you ensure storage1's access keys are rotated automatically?

An Azure Key Vault is the correct solution because it can securely store and manage secrets, including storage account access keys. Key Vault offers features like automatic key rotation for secrets, ensuring that access keys are regularly updated without manual intervention, which enhances security. Backup vaults and Recovery Services vaults are used for backup and disaster recovery, not for managing storage account access keys. Changing redundancy for storage1 affects data replication, not key management. Lifecycle management for storage1 is used for managing blob data retention and tiering, not for rotating access keys.
