QID:BCM21 - 802.1Q can only be configured on a Layer 2 port... Incorrect
#1
Hello,

Cisco's website seems to contradict your claim that 802.1Q trunking can only be configured on a Layer 2 port.  Of course it can be configured on a routers sub-interfaces but how about a switches?  Please see link as it clearly demonstrates 802.1Q configuration being set up on a switches sub-interface which is operating on a LAYER 3 port.  So you might want to reconsider your answer:

http://www.cisco.com/en/US/docs/switches...r3int.html

switch(config-subif)# encapsulation dot1Q 33

7. (QID:BCM21) Which statement is correct about 802.1Q trunking? (Select all that apply)

In 802.1Q trunking, all VLAN packets are tagged on the trunk link, except the native VLAN.
Both switches must be in the same VTP domain.
802.1Q trunking can only be configured on a Layer 2 port.
The encapsulation type of both ends of the trunk does not have to match.
The native VLAN on both ends of the trunk must be VLAN 1.

Correct Answer: 802.1Q trunking can only be configured on a Layer 2 port.
                       In 802.1Q trunking, all VLAN packets are tagged on the trunk link, except the native VLAN.

Hey,

    It occurs to me the question is intended to probe comprehension of executing a "no switchport" on a standard layer 2 ('switching') port.  As far as I know the other 3 options generally false irrespective of context.
