220-1102 Question 118
Single answerrobocopyA technician needs to copy a user's profile data from an old Windows PC to a new one over the network. The user has many large folders, and the technician wants the copy to resume if the connection drops instead of restarting the entire transfer. Which robocopy command-line switch should the technician use to best meet this requirement?
- A
/Z
- B
/MIR
- C
/MOV
- D
/LOG
Show answer and explanation
Correct answer: A
Explanation
The best answer is /Z because restartable mode is designed for network copies that may be interrupted. In a real-world migration, this helps avoid wasting time retransferring large files from the beginning after a brief disconnect. By contrast, /MIR is for mirroring source and destination folder structures, /MOV is for moving rather than copying, and /LOG only records the operation. Microsoft documentation for robocopy identifies /Z as restartable mode, which is a standard best practice when copying across less reliable network links.
- A. Correct.
Correct. The /Z switch enables restartable mode, which allows robocopy to resume copying a file after a network interruption instead of starting that file over from the beginning. This is especially useful for large files being copied across unstable network connections.
- B. Incorrect.
Incorrect. The /MIR switch mirrors a directory tree, making the destination match the source, including deleting files and folders at the destination that no longer exist in the source. It is useful for synchronization but does not provide restartable transfer capability. A technician might choose this option because it is commonly used for profile migrations, but it addresses folder matching, not interrupted transfers.
- C. Incorrect.
Incorrect. The /MOV switch moves files to the destination and deletes them from the source after copying. This is not appropriate when the requirement is specifically to resume interrupted transfers. It also creates unnecessary risk during a migration because the source files are removed.
- D. Incorrect.
Incorrect. The /LOG switch writes robocopy output to a log file. Logging is helpful for documentation and troubleshooting, but it does not affect how file transfers behave during a network interruption. Someone might choose this option because logs are often recommended during migrations, but it does not solve the stated problem.
