The correct answer is A. 443 TCP B. 902 TCP and UDP C. 903 TCP. The vSphere Web Client uses ports 443, 902, and 903 when establishing a direct connection to an ESXi 6.x host for management, data transfer, and remote console access.

Why each option
The vSphere Web Client uses ports 443, 902, and 903 when establishing a direct connection to an ESXi 6.x host for management, data transfer, and remote console access.
Port 443 TCP is the standard HTTPS port used for all Web Client management communication with the ESXi host's hostd management agent.
Port 902 TCP and UDP is used by the ESXi host for VMware Remote Console (VMRC) traffic and NFC (Network File Copy) data transfers initiated from the Web Client.
Port 903 TCP is used specifically for VM remote console connections (legacy VMRC protocol) from the client browser directly to the ESXi host.
Port 5480 TCP is the management port for the VMware Appliance Management Interface (VAMI) on the vCenter Server Appliance and is not involved in direct ESXi host connections.
Port 9443 TCP and UDP is the listening port of the vSphere Web Client service running on vCenter Server itself, not a port used when connecting directly to an ESXi host.
