You have been tasked with setting a trust boundary on the Company network.
What is the basic function of this trust boundary？（）
A. Trust boundaries are points in the network where Layer 2 CoS markings are converted to Layer 3 DSCP or IP precedence markings.
B. Trust boundaries are a point in the network where QoS functionality begins and ends.
C. Trust boundaries determine whether certain types of traffic can pass.
D. Trust boundaries are a point in the network where decisions about CoS markings on incoming packets are made.
E. None of the other alternatives apply

Refer to the exhibit. On basis of the configuration that is provided，
where will the trust boundary be established in this network？ （）
A.at the PC
B.at the access switch
C.at the IP phone
D.at the distribution switch
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？ （）
A.The CoS is trusted for 802.1P or 802.1Q tagged traffic.
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 statement is true about where trust boundaries should be established in a network？（）
A.Endpoints 2 and 3 are optimal places to establish a trust boundary. Endpoint 1 is an acceptable place to establish a trust boundary.
B.Endpoint 2 is the optimal place to establish a trust boundary. Endpoints 1 and 3 are acceptable places to establish a trust boundary.
C.Endpoint 2 is the only acceptable place to establish a trust boundary.
D.Endpoint 1 is the only acceptable place to establish a trust boundary.
E.Endpoints 1 and 2 are optimal places to establish a trust boundary. Endpoint 3 is an acceptable place to establish a trust boundary.
F.Endpoint 1 is the optimal place to establish a trust boundary. Endpoints 2 and 3 are acceptable places to establish a trust boundary.

Which statement is correct about RSTP port roles？（）
Refer to the exhibit. On the basis of the output of the show spanning-tree inconsistentports command， which statement about interfaces FastEthernet 0/1 and FastEthernet 0/2 is true？（）
During routine maintenance， it became necessary to shutdown G1/0/1 on DS1 and DS2. All other interface were up. During this time， DS1 became the active device for Vlan104’s HSRP group. As related to Vlan104’s HSRP group. What can be done to make the group function properly ？ （）
Refer to the exhibit. For what purpose is the command show ip cef used？（）
Refer to the exhibit. The command switchport mode access is issued on interface FastEthernet0/13 on switch CAT1. What will be the result？（）
Refer to the exhibit and the partial configuration of switch SW_A and SW_B. STP is configured on all switches in the network. SW_B receives this error message on the console port：00：06：34： %CDP-4-DUPLEX_MISMATCH： duplex mismatch discovered on FastEthernet0/5 （not half duplex）， with SW_A FastEthernet0/4 （half duplex） ， with TBA05071417（Cat6K-B） 0/4 （half duplex）. What would be the possible outcome of the problem？（）
What is the configured priority value of the Vlan105’s group on DS2 ？（）
Refer to the exhibit. Switch 15 is configured as the root switch for VLAN 10 but not for VLAN 20. If the STP configuration is correct， what will be true about Switch 15？（）
Refer to the exhibit. STP has been implemented in the network. Switch SW_A is the root switch for the default VLAN. To reduce the broadcast domain， the network administrator decides to split users on the network into VLAN 2 and VLAN 10. The administrator issues the command spanning-tree vlan 2 root primary on switch SW_A. What will happen as a result of this change？（）
Which router redundancy protocol cannot be configured for interface tracking？（）
