A.
The trunk link belongs to a specific VLAN.
B.
Multiple trunk links are used to connect multiple end user devices.
C.
A trunk link only supports native VLAN.
D.
Trunk links use 802.10 to identify a VLAN.
E.
The native VLAN of the trunk link is the VLAN that the trunk uses for untagged packets.
Explanation:
A trunk is a point-to-point link that transmits and receives traffic between switches or between
switches and routers. Trunks carry the traffic of multiple VLANs and can extend VLANs across an
entire network. 100BaseT and Gigabit Ethernet trunks use Cisco ISL (the default protocol) or
industry-standard IEEE 802.1Q to carry traffic for multiple VLANs over a single link. Frames
received from users in the administratively-defined VLANs are identified or tagged for transmission
to other devices. Based on rules you define, a unique identifier (the tag) is inserted in each frame
header before it is forwarded. The tag is examined and understood by each device before any
broadcasts or transmission to other switches, routers, or end stations. When the frame reaches
the last switch or router, the tag is removed before the frame is transmitted to the target end
station.
