What is the effect of applying the switchport trunkencapsulation dot1q command to a port on a Cisco Catalyst
switch?

A.
By default, native VLAN packets going out this port are tagged

B.
Without an encapsulation command, 802.1Q is the default encapsulation if DTP fails to negotiate a trunking
protocol

C.
The interface supports the reception of tagged and untagged traffic

D.
If the device connected to this port is not 802.1Q-enabled, it is unable to handle 802.1Q packets
