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

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.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

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.

B.A switch is listening to VTP advertisements from their own domain only
C.A switch is listening to VTP advertisements from multi domains
D.A switch can reside in one or more domains
E.VTP is no longer supported on Catalyst switches
A.VTP messages will not be forwarded over nontrunk links.
B.VTP domain names need to be identical. However，case doesn’t matter.
C.A VTP enabled device which receives multiple advertisements will ignore advertisements with higher configuration revision numbers.
D.A device in "transparent" VTP v.1 mode will not forward VTP messages.
E.VTP pruning allows switches to prune VLANs that do not have any active ports associated with them.
