Refer to the exhibit.

On the basis of the output generated by the show commands, which two statements are true? (Choose two.)

A.
Because it is configured as a trunk interface, interface gigabitethernet 0/1 does not
appear in the show vlan output.

B.
VLAN 1 will not be encapsulated with an 802.1q header.

C.
There are no native VLANs configured on the trunk.

D.
VLAN 2 will not be encapsulated with an 802.1q header.

E.
All interfaces on the switch have been configured as access ports.

F.
Because it has not been assigned to any VLAN, interface gigabitethernet 0/1 does not
appear in the show vlan output.

Explanation:
The IEEE 802.1Q protocol can also carry VLAN associations over trunk links. However, this
frame identification method is standardized, allowing VLAN trunks to exist and operate
between equipment from multiple vendors.
In particular, the IEEE 802.1Q standard defines an architecture for VLAN use, services
provided with VLANs, and protocols and algorithms used to provide VLAN services.

Like Cisco ISL, IEEE 802.1Q can be used for VLAN identification with Ethernet trunks.
Instead of encapsulating each frame with a VLAN ID header and trailer, 802.1Q embeds its
tagging information within the Layer 2 frame. This method is referred to as single-tagging or
internal tagging.
802.1Q also introduces the concept of a native VLAN on a trunk. Frames belonging to this
VLAN are not encapsulated with any tagging information. In the event that an end station is
connected to an 802.1Q trunk link, the end station can receive and understand only the
native VLAN frames. This provides a simple way to offer full trunk encapsulation to the
devices that can understand it, while giving normal access stations some inherent
connectivity over the trunk.
show vlan: This commands shows the vlan, ports belonging to VLAN means that port on
access mode. It doesn’t show the port on trunk mode.
