問題文

A technician has to put a set of settings held on a file store back onto a switch exactly as it was written. Which statement is correct?

選択肢

1. Sending the file to the settings in force mixes it in with the lines already there, so an exact copy needs the file to go to the saved settings and the box to be started again.
2. Sending the file to the saved settings mixes it in with the lines already there, so an exact copy calls for sending it to the settings in force after wiping the older lines by hand.
3. Sending the file to the settings in force wipes the lines already there, so an exact copy calls for that one step and for little else.
4. Sending the file to the settings in force mixes it in with the lines already there, so an exact copy takes a wipe of the saved settings by hand before the file is sent.
