Which three of these statements regarding 802.1 Q trunking are correct? (Choose three.)

Which three of these statements regarding 802.1 Q trunking are correct? (Choose three.)

A.
802.1 Q native VLAN frames are untagged by default.

B.
802.1 Q trunking ports can also be secure ports.

C.
802.1 Q trunks can use 10 Mb/s Ethernet interfaces.

D.
802.1 Q trunks require full-duplex, point-to-point connectivity.

E.
802.1 Q trunks should have native VLANs that are the same at both ends.

Explanation:
By default, 802.1Q trunk defined Native VLAN in order to forward unmarked frame. Switches can
forward Layer 2 frame from Native VLAN on unmarked trunks port. Receiver switches will transmit
all unmarked packets to Native VLAN. Native VLAN is the default VLAN configuration of port.
NotE. for the 802.1Q trunk ports between two devices, the same Native VLAN configuration is
required on both sides of the link. If the Native VLAN in 802.1Q trunk ports on same trunk link is
properly configured, it could lead to layer 2 loops. The 802.1Q trunk link transmits VLAN
information through Ethernet.
