A Windows utility used to set the NTFS volume behavior parameter, DisableLastAccess, which controls enabling or disabling of the last access timestamp.

• A. Cipher.exe
• B. Bash
• C. DNS tunneling
• D. fsutil

Answer: (D)

Disabling or enabling the update of the last access timestamp on NTFS volumes is a Windows-specific behavior you can configure with a built-in tool that manages file system settings. The command-line utility that exposes this capability is fsutil, which includes a subcommand to adjust file-system behavior. By using fsutil behavior set DisableLastAccess 1, you tell Windows not to update the last access time when files are opened, which reduces disk writes and can improve performance on busy systems. To re-enable, you’d set DisableLastAccess to 0. The other options don’t provide a way to alter NTFS behavior: Cipher.exe handles EFS encryption tasks, Bash is a Unix-like shell, and DNS tunneling is a network technique, not a Windows file-system setting.
