FTP

Which statement(s) about are FTP True?

FTP always uses two separate TCP sessions ? one for control and one for data.

With passive mode FTP, both the control and data TCP sessions are initiated from the client.

With active mode FTP, the server uses the ?PORT? command to tell the client on which port it wished to send the data.

For both active and passive mode FTP, the control session on the server always uses TCP port 21, and the data session always uses TCP port 20.

FTP does not have active and passive modes.

Re: FTP

hi

i would choose :

With passive mode FTP, both the control and data TCP sessions are initiated from the client.

With active mode FTP, the server uses the ?PORT? command to tell the client on which port it wished to send the data

(FTP (in passive or active mode)uses two ports one for data and one for control)

Re: FTP

I feel correct answers are A,B,C

Re: FTP

A, B are true.

C is false. The client uses the port command not the server.

D is also false since in passive mode the server will use a random port for the data session. This port is communicate to the client in response to the PASV command.

Hope this helps,
