A BIG-IP Administrator needs to configure the BIG-IP system to perform load balancing for FTP servers running passive mode FTP. How should the administrator configure the Virtual Server to perform thi

A Standard Virtual Server operates as a full proxy, allowing the BIG-IP to actively manage both the control and data channels required by FTP. The FTP profile specifically understands the FTP protocol commands, including PASV, to dynamically create data channel connections and correctly translate IP addresses and ports for passive mode FTP sessions.

A Forwarding Virtual Server simply forwards packets without modifying them or performing application-layer inspection, which is insufficient for managing passive FTP data channels.

A Performance Layer 4 Virtual Server provides high-performance TCP/UDP load balancing but lacks the application-layer intelligence of an FTP profile to handle passive FTP control and data channel negotiation.

A Message Routing Virtual Server is specialized for message-based protocols like SIP or Diameter and is not applicable to standard FTP load balancing.
