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.
This describes which technology？（）
A. DISL
B. ISL
C. DTP
D. IEEE 802.1Q
E. MPLS
F. None of the other alternatives apply

E. Configuration revision number
Switch R1 is configured with VTP.
Which two VTP modes will make R1 capable of creating and deleting VLANs on itself？ （）
A. Client
B. Server
C. Transparent
D. Pass-through
E. No-negotiate
What action should you execute if you wanted to enable VTP pruning on your entire management domain？（）
A. Enable VTP pruning on any client switch in the management domain.
B. Enable VTP pruning on any switch in the management domain.
C. Enable VTP pruning on every switch in the management domain.
D. Enable VTP pruning on a VTP server in the management domain.
E. Disable VTP pruning on a VTP server in the management domain.
A.It does not prune traffic from VLANs that are pruning-ineligible
B.VLAN 1 is always pruning-eligible
C.It will prune traffic from VLANs that are pruning-ineligible
D.VLAN 2 is always pruning-ineligible
E.None of the other alternatives apply
A.Domain advertisements
B.Advertisement requests from clients
C.Subset advertisements
D.Summary advertisements
A.The VLAN ID of all known VLANs，the management domain name，and the total number of trunk links on the switch.
B.The VLAN ID of all known VLANs，a 1-bit canonical format （CF1 Indicator），and the switch configuration revision number.
C.The management domain name，the switch configuration revision number，the known VLANs， and their specific parameters.
D.A 2-byte TPID with a fixed value of 0x8100 for the management domain number，the switch configuration revision number，the known VLANs，and their specific parameters.
E.None of the other alternatives apply.
A.A number for identifying changes to the network switch.
B.A number for identifying changes to the network router.
C.A number for identifying changes to the network topology.
D.None of the other alternatives apply.
