A police officer often leaves a workstation for several minutes at a time. Which of the following is the BEST way the officer can secure the workstation quickly when walking away?

Using a key combination, such as Windows key + L on Windows or Command + Control + Q on macOS, immediately locks the workstation, requiring authentication to regain access. This is the quickest and most effective way to secure a device when stepping away for any period, preventing unauthorized individuals from accessing sensitive information.

Ensuring no unauthorized personnel are in the area is a physical security measure, but it does not technically secure the workstation itself from physical access or manipulation if someone does gain entry.

Configuring a screensaver to lock after 30 minutes is too long for "several minutes" of absence, leaving the workstation vulnerable for a significant period.

Turning off the monitor only prevents visibility of information on the screen; the workstation remains unlocked and accessible, allowing an unauthorized user to turn the monitor back on or perform actions blindly.
