An engineer needs to upload a configuration file to a router using FTP. The router is behind a firewall that only allows outbound TCP connections on port 21. Will the FTP transfer work?

Yes, because FTP uses UDP and does not need additional ports

No, because FTP requires both ports 20 and 21 to be open in all cases

Yes, because FTP uses only port 21 for both control and data

No, because FTP data connections use a separate port that may be blocked
