Command that displays VTP information on the switch.
sh vtp status
Verifies the VTP name, mode, revision number, and other information.
This command Indicates if VTP updates are being sent and received by the switch.
sh vtp counters
This command Displays the parameters for all configured VLANs. On a client, it will indicate if VTP updates are being received by the switch.

True.
CDP must be enabled on an interface for a voice access port to work with Cisco IP Phones?
Cisco switches and routers enable CDP by default.
Configure interfaces fa 1 - 4 that are connected to phones to allow vlans 11 for voice and vlan 10 for data?
What command would you use to verify the status of one of the interfaces.
#conf t #vlan 10 #vlan 11 #int range fa0/1-4 #switchport mode access #switchport access vlan 10 #switchport voice vlan 11
Check interface status
#show int fa0/4 switchport #show interfaces switchport
What are the 4 steps used to Tshoot VLANS and VLAN Trunks?
- Confirm that all vlans are both defined and active.
- Check the allowed vlan lists on both ends of each trunk to ensure that all vlans intended to be used are included.
- Check for incorrect trunk config. setting that result in one switch operating as a trunk.
- Check the native vlan settings on both ends of the trunk to ensure that both match.
What command allows the network engineer a method to administratively limit the vlans whose traffic uses a trunk?
#conf t #switchport trunk allowed vlan [vlan / vlan range 1-60]
