You need to determine where the trust boundaries will be in a new Company VOIP design.
Which two statements are true about these trust boundaries？（）
A.Trust boundaries are configured in the core of the network to provide the most efficient forwarding based upon QoS markings，
B.Setting trust boundaries at the edge of the network allows intermediate hop devices to administer QoS policies without detailed packet identification.
C.Trust boundaries are used to determine which QoS mechanism will be applied to the traffic.
D.At the trust boundaries， the untrusted traffic will be marked with a new QoS value appropriate for the policy in place at the point where the traffic entered the campus network.
E.Trust boundaries define the firewall rules for QoS admission into a network.

Refer to the exhibit. Based upon the information that is given，
how will voice traffic from the phone and data traffic from the PC be handled by SW_1？ （）
A.The switch port will perform marking for the ingress voice and data traffic by using the defaultCoS value at the switch port.
B.The switch port will trust theCoS value of the ingress voice and data traffic that comes into the switch port.
C.The switch port will trust theCoS value of the ingress voice traffic. Data traffic will be marked at the switch port with the default CoS value.
D.The switch port will trust theCoS value of the ingress data traffic. Voice traffic will be marked at the switch port with the default CoS value.
The voice VLAN feature has been enabled on a new Company Catalyst switch port.
What is the effect of this？ （）

B.PortFast is disabled on the port.
C.Port Security is automatically enabled on a voice VLAN port.
D.Untagged traffic is sent according to the default CoS priority of the port.
E.None of the other alternatives apply
Refer to the exhibit.

Which three statements are true about the voice VLAN feature on this switch？（）
A.The default CoS value for incoming traffic is set up to 0.
B.The CoS value is trusted for 802.1p or 802.1q tagged traffic.
C.PortFast is automatically disabled when a voice VLAN is configured.
D.The voice VLAN feature is disabled by default.
E.The IP phone accepts the priority of all tagged and untagged traffic and sets the CoS value to 4.
F.When the voice VLAN feature is enabled， all untagged traffic is sent according to the default CoS priority of the port
Refer to the exhibit. Which statement is true about a voice VLAN？（）
A.Physically the voice network and the data network are separate.
B.The voice traffic will normally be on a different IP subnet than will the data traffic.
C.End user intervention is necessary to place the phone into the proper VLAN.
D.The same security policy should be implemented for both voice and data traffic.
E.The data VLAN must be configured as the native VLAN.
