Which of the following is a reason to enable audit object access on a file share?

Enabling audit object access on a file share is primarily geared towards gaining insight into activities related to the files stored on that share. The best practice for enabling this feature is to track specific actions, especially when it comes to sensitive or critical data management.

When you choose to audit object access, it logs detailed information about which users accessed files, what actions they took, whether files were created, modified, or deleted, and when these actions occurred. This is essential for maintaining data integrity and security, particularly in environments where data governance is important.

In the context of the choices provided, tracking who deleted files from the share stands out as a key reason for enabling this feature. By auditing deletions, an organization can respond to incidents of file loss, whether accidental or malicious, and can reconstruct events surrounding the deletion. This not only assists in recovery efforts but also helps in building accountability among users who have access to the share.

While preventing unauthorized access, determining who accessed a file last, and monitoring bandwidth usage provide valuable information, they do not focus primarily on the auditing functionality tied to tracking specific user actions regarding file deletions, which is the critical role of enabling audit object access.
