A new Company switch was just configured using the "switchport trunk native vlan 7" command.
What does this interface command accomplish？（）
A. Causes the interface to apply ISL framing for traffic on VLAN 7
B. Configures the trunking interface to forward traffic from VLAN 7
C. Configures the interface to be a trunking port and causes traffic on VLAN 7 to be 802.1q tagged
D. Configures the trunking interface to send traffic from VLAN 7 untagged
E. None of the other alternatives apply
