*Which port does the FTP service listen on usually?*

### <mark style="color:purple;">Answer</mark>

21

### <mark style="color:purple;">Explanation</mark>

This is the default port for FTP control connections, where commands are sent from the client to the server. Data transfer for FTP can occur on different ports depending on the mode (active or passive), but port 21 is where the connection is initially established.
