Which statement best describes the protocol used in a passive FTP session?

The statement identifying that a passive FTP session is easier for firewalls to process accurately reflects how passive FTP operates. In passive mode, the client initiates both the control and data connections, which is less complex for firewall configurations compared to active mode, where the server connects back to the client. Firewalls typically allow outbound connections more readily, which aligns with the passive mode requirement.

This simplicity reduces the chances of connection issues when traversing firewalls, as most firewalls are configured to block unsolicited inbound traffic. Thus, using passive mode mitigates potential barriers caused by strict firewall settings, making it a preferred option in many network environments.

The other statements inaccurately describe FTP session types or do not convey the purpose of passive FTP in the context of enhancing compatibility with firewalls and network security.
