質問 2：
You are deploying IP phones in your enterprise networks. When plugged in, the IP phones must be automatically provided with the correct VLAN ID needed for sending voice traffic to the EX Series switches.
In this scenario, which two solutions are required to accomplish this task? (Choose two.)
A. Enable the voice VLAN feature with the appropriate access interfaces and VLAN ID for voice traffic.
B. Enable LLDP-MED on appropriate access interfaces.
C. Create two VLANs and assign them as VLAN members to the appropriate access interfaces.

正解：A,B

質問 3：
Remote branches connect to the corporate WAN through access switches. The access switches connect to access ports on the WAN distribution switch, as shown in the exhibit. L2PT has previously been configured on the tunnel Layer 2 traffic across the WAN. You decide to move the L2PT tunnel endpoints to the access switches. When you apply the L2PT configuration to the access switches, the ports that connect the access switches to the distribution switch shut down.
Which action would solve this problem?

A. Configure a GRE tunnel to encapsulate the L2PT traffic across the WAN.
B. Disable the BPDU block function on the distribution switch.
C. Disable the BPDU block function on the access switches.
D. Configure the links between the access switches and the distribution switch as a trunk port.
