A SAN fabric is built between a pair of Cisco MDS 9000 Series Switches. The requirement is for the ISL to use the VSAN ID to toward traffic from multiple VSANs across the same physical link. Additiona

This is a duplicate option of B, which is the correct answer.

Configuring the interface with `switchport mode TE` sets it as a Trunking E-Port. TE-Ports are essential for ISLs (Inter-Switch Links) that need to carry traffic for multiple VSANs using VSAN tagging, and they support advanced Fibre Channel features like Fibre Channel trace.

Configuring an interface in `switchport mode E` sets it as an E-Port, which can form an ISL but only carries traffic for a single VSAN and does not support VSAN tagging to transport multiple VSANs over the same physical link.

This is a duplicate option of C, which is incorrect.
