Ethernet 1/0/1 and Ethernet 1/0/2 of Switch A are each connected to a Cisco IP phone.  

z 

Configure voice VLAN 2 on Switch A. Enable CDP compatibility of LLDP on Switch A to allow the 

Cisco IP phones to automatically configure the voice VLAN, thus confining their voice traffic within 

the voice VLAN to be isolated from other types of traffic.
