第8题:
IP phones require inline power and must be in separate VLAN to receive inline power
IP telephony applications require prioritization over other traffic as they are more delaysensitive

第10题:
Voice VLANs are only used when connecting an IP phone and a host to distinct switch ports
Access ports that are configured with voice VLANs will always trust the CoS that is received from IP phones
Access ports that are configured with voice VLANs may or may not override the CoS value that is received from an IP phone
Voice VLANs are configured using the switchport voice vlan vlan-ID interface configuration command
Voice VLANs provide a trunking interface between an IP phone and an access port on a switch to allow traffic from multiple devices that are connected to the port
Enabling Voice VLAN on a switch port will automatically configure the port to trust the incoming CoS markings
第11题:
Physically the voice network and the data network are separate
The voice traffic will normally be on a different IP subnet than will the data traffic
End user intervention is necessary to place the phone into the proper VLAN
The same security policy should be implemented for both voice and data traffic
The data VLAN must be configured as the native VLAN
第12题:
When the voice VLAN feature is enabled, all untagged voice and data traffic is sent through the voice VLAN.
The voice VLAN feature is enabled by default.
The IP phone overrides the priority of all incoming data traffic (tagged and untagged) and sets the CoS value to 0.
The default CoS value is 1 for incoming voice and data traffic.

第20题:
device PoE requirements
device IP address
device voice VLAN ID
device platform
第21题:
Physically the voice network and the data network are separate.
The voice traffic will normally be on a different IP subnet than will the data traffic.
End user intervention is necessary to place the phone into the proper VLAN.
The same security policy should be implemented for both voice and data traffic.
The data VLAN must be configured as the native VLAN.
第22题:
The CoS value is trusted for 802.1p or 802.1q tagged traffic.
The voice VLAN feature is disabled by default.
The IP phone accepts the priority of all tagged and untagged traffic and sets the CoS value to 4.
When the voice VLAN feature is enabled, all untagged traffic is sent according to the default CoS priority of the port.
PortFast is automatically disabled when a voice VLAN is configured.
The default CoS value for incoming traffic is set to 0.
第23题:
