Which purpose is a valid reason to change the mode of an interface to a TE Port on a Cisco Nexus 6000 Series switch?
The correct answer is D. to create a VSAN trunk. A TE (Trunking Expansion) port on the Cisco Nexus 6000 enables VSAN trunking over a single Fibre Channel ISL, carrying frames from multiple VSANs simultaneously.

Why each option
A TE (Trunking Expansion) port on the Cisco Nexus 6000 enables VSAN trunking over a single Fibre Channel ISL, carrying frames from multiple VSANs simultaneously.
Connecting to a third-party SAN switch uses a standard E port in interoperability mode, not a TE port, because proprietary trunking extensions may not be supported by the third-party device.
Spanning a Fibre Channel port is accomplished through SPAN/RSPAN configuration on dedicated monitoring ports, which is unrelated to the TE port mode.
Linking an NPV switch to a core switch uses NP ports on the NPV device and F ports (or TF ports for trunking) on the core, not TE ports.
The TE port is the trunking variant of an E port; it negotiates a list of allowed VSANs with the peer switch and tags each frame with its VSAN ID, allowing a single physical ISL to carry traffic from many VSANs - the primary reason to configure this mode.
