C. The protocol uses point-to-multipoint connectivity
D. The protocol uses point-to-point connectivity
E. The IEEE 802.1Q frame uses multicast destination of 0x01-00-0c-00-00
F. The IEEE 802.1Q frame retains the original MAC destination address
Refer to the exhibit. On the basis of the output generated by the show commands，
which two statements are true？（）

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.
