 38.  B.  You must manually configure the VLAN on the Cisco switch(s). VTP is a protocol 

that allows for VLAN autoconfiguration in the VLAN database. However, only Cisco 

switches support it. Setting the correct trunking protocol between the switches will help 

guarantee VLANs can traverse between switches. Configuring VTP is only possible on 

Cisco switches because it is a proprietary protocol. Assigning the VLAN to an interface on 

the other switch will not fix the problem.

 39.  B.  When a VLAN is created, so is a broadcast domain. The broadcast domain/VLAN 

requires its own unique IP network addressing and a router to route between the 

networks. Therefore, you need a router for inter-VLAN communications. The VLANs will 

automatically be in a no shutdown mode when they are configured initially. The VLANs 

do not require VTP to be configured, although it is helpful. The interfaces associated with 

VLANs are automatically in a no shutdown mode.

 40.  C.  The command 

show ip interface brief will display only the necessary information 

of interface, IP, and status to aid in the diagnostic process. The command 

show ip 

interface is incorrect. The command show interface is incorrect. The command show 

interface brief is incorrect.

 41.  B.  Switch A and Switch B are participating in VLAN tagging. Therefore, Switch A 

interface Gi0/1 and Switch B interface Gi0/1 are both configured as trunk switch ports. 

This will allow VLAN tagging across the trunk link. Switch A interface Gi0/1 cannot be 

configured as an access switch port because tagging of VLANs between switches would not 

occur. Switch B interface Fa0/1 shows no sign of being configured with a duplicate VLAN 

ID. Switch A interface Fa0/3 shows no sign of being configured with a duplicate VLAN ID.

 42.  B.  Since the Dell switch cannot support the proprietary protocol of Inter-Switch Link 

(ISL), both switches need to be set up to use 802.1Q. Although both switches need to have 

duplicate VLAN configurations, that will not prevent them from creating a trunk between 

themselves. VTP cannot be configured on both of the switches because VTP is a Cisco 

proprietary protocol.

 43.  B.  The command 

show interfaces trunk will display all of the configured trunks on 

the switch. The command 

show interfaces brief is incorrect. The command show 

switchport trunk is incorrect. The command show switchport brief is incorrect.

 44.  A.  All switches are configured by default as a VTP server. A switch configured as a 

client will receive and process VTP packets from a VTP server. A switch configured as 

transparent will not participate in VTP but will allow VTP to be forwarded to other 

switches. There is no such mode as master with VTP.

 45.  B.  The command to display the mode settings for VTP is 

show vtp status. The 

command 

show vtp is incorrect. The command show vtp counters is incorrect. The 

command 

show running-config is incorrect.

 46.  B.  When setting up VTP on a new switch connected to your existing VTP infrastructure, 

you need to change the mode of the switch. Then you must configure the VTP domain 

that is serving the VTP information. The transparent mode for VTP will not allow the 

switch to participate in VTP processing. Setting the VTP domain alone will not allow the 

switch to participate in VTP because it must be switched to the mode of client as well. The 

command 

vtp corpname is not a valid command.
