Question #: 13
Topic #: 1
[All HP0-Y47 Questions]

Refer to the exhibit.

An HP Comware Switch connects to Voice over (VoIP) phones. The phones connect to users computes, so each switch port connects a computer and a phone.
These are the specifications:
✑ The VLAN for data traffic is VLAN3
✑ The VLAN for traffic VoIP is VLAN11
✑ The phones support Link Layer Discovery Protocol (LLDP) Media Endpoint Detection (MED).
The network administrator wants to use LLDP-MED to advertise the voice VLAN ID and priority settings to the phones. The phones will then send tagged traffic in that VLAN. The switch should not check the incoming traffics MAC address against its voice OID list. The exhibit shows the applicable switch port configuration.
Which additional step must the administrator complete to accomplish this?

  • A. Enable voice VLAN 11 (voice vlan 11 enable)
  • B. Change the port to trunk mode (port link-type trunk)
  • C. Enable LLDP compatibility with Cisco Discovery Protocol (CDP) (lldp compliance admin-status cdp txrx)
  • D. Enable the port to advertise voice VLAN 11 with LLDP (lldp voice-vlan 11)
