A new Company switch was just configured using the "switchport trunk native vlan 7" command.
What does this interface command accomplish？（）
A. Causes the interface to apply ISL framing for traffic on VLAN 7
B. Configures the trunking interface to forward traffic from VLAN 7
C. Configures the interface to be a trunking port and causes traffic on VLAN 7 to be 802.1q tagged
D. Configures the trunking interface to send traffic from VLAN 7 untagged
E. None of the other alternatives apply

Switch R1 has been configured with DTP using the desirable option.
Which statement describes Dynamic Trunking Protocol （DTP） desirable mode？（）
A. The interface actively attempts to convert the link to a trunk link.
B. The interface is put into permanent trunking mode but prevented from generating DTP frames.
C. The interface is put into permanent trunking mode and negotiates to convert the link into a trunk link.

E. None of the other alternatives apply
The core Company switches are configured to use 802.1Q trunks.
Which three statements are correct with regard to the IEEE 802.1Q standard？（）
A. The IEEE 802.1Q frame format adds a 4 byte field to a Ethernet frame
B. The packet is encapsulated with a 26 byte header and a 4 byte FCS
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？（）
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.
The Company core switches use 802.1Q trunks to connect to each other.
How does 802.1Q trunking keep track of multiple VLANs？ （）
A. It tags the data frame with VLAN information and recalculates the CRC value
B. It encapsulates the data frame with a new header and frame check sequence
C. It modifies the port index of a data frame to indicate the VLAN
D. It adds a new header containing the VLAN ID to the data frame
E. None of the other alternatives apply
Two Company switches are connected via a trunk link. In this network， the original frame is encapsulated and an additional header is added before the frame is carried over a trunk link. At the receiving end， the header is removed and the frame is forwarded to the assigned VLAN.

A. DISL
B. ISL
C. DTP
D. IEEE 802.1Q
E. MPLS
F. None of the other alternatives apply
