A technician needs to synchronize a folder structure from a file server to a backup server so that files deleted from the source are also removed from the destination during the copy job. Which robocopy switch accomplishes this?
/MIR mirrors a directory tree, copying new/changed files and deleting files at the destination that no longer exist at the source, keeping both locations identical.
A technician modified a Group Policy Object and now needs to verify exactly which policy settings are currently being applied to a specific user on a workstation, without forcing a new policy refresh. Which command should the technician run?
gpresult /r displays the Resultant Set of Policy (RSoP) summary, showing which GPOs and settings are currently applied to the logged-on user and the computer.
A Windows server has run out of available drive letters, but a new NTFS volume must be added and made accessible through an existing empty folder on the C: drive. Which Disk Management action should the technician perform?
Disk Management allows a volume to be mounted to an empty NTFS folder (a mount point) instead of a drive letter, providing access to the new volume without requiring an available letter.
A Linux administrator needs to give the file owner full read, write, and execute permissions while removing all permissions for the group and all other users. Which command accomplishes this?
chmod 700 sets permissions to rwx (7) for the owner and 0 (no access) for both group and others, matching the requirement exactly.
A technician runs netstat -ano on a Windows workstation and notices an ESTABLISHED connection to an unfamiliar external IP address on port 4444, associated with PID 6120. Which tool should the technician use next to identify the process image name behind that PID?
Task Manager's Details tab includes a PID column, letting the technician match the suspicious PID to its process image name and take action such as ending the task.
A user needs to store video files larger than 4GB on a USB flash drive that will be swapped between a Windows 11 workstation and a macOS system, with full native read/write access required on both platforms. Which file system should the technician choose when formatting the drive?
exFAT supports files larger than 4GB and is natively readable and writable by both Windows and macOS without additional drivers, making it ideal for cross-platform removable media.
