NEW QUESTION: 2
Configuration of which option is required on a Cisco switch for the Cisco IP phone to work?
A. Cisco Discovery Protocol in global configuration mode
B. a voice VLAN ID in interface and global configuration mode
C. the interface as an access port to allow the voice VLAN ID
D. PortFast on the interface
Answer: C
Explanation:
Configure the Switch Port to Carry Both Voice and Data TrafficWhen you connect an IP phone to a switch using a trunk link, it can cause high CPU utilization in the switches. As all the VLANs for a particular interface are trunked to the phone, it increases the number of STP instances the switch has to manage. This increases the CPU utilization. Trunking also causes unnecessary broadcast / multicast / unknown unicast traffic to hit the phone link. In order to avoid this, remove the trunk configuration and keep the voice and access VLAN configured along with Quality of Service (QoS). Technically, it is still a trunk, but it is called a Multi-VLAN Access Port (MVAP).
Because voice and data traffic can travel through the same port, you should specify a different VLAN for each type of traffic. You can configure a switch port to forward voice and data traffic on different VLANs. Configure IP phone ports with a voice VLAN configuration. This configuration creates a pseudo trunk, but does not require you to manually prune the unnecessary VLANs.
The voice VLAN feature enables access ports to carry IP voice traffic from an IP phone.
The voice VLAN feature is disabled by default. The Port Fast feature is automatically enabled when voice VLAN is configured. When you disable voice VLAN, the Port Fast feature is not automatically disabled.
Hotspot Question - RIPv2 Troubleshooting I (QUESTION 274 - QUESTION 277) Scenario:
You work for a company that provides managed network services, and of your real estate clients running a small office is experiencing network issues, Troubleshoot the network issues.
Router R1 connects the main office to internet, and routers R2 and R3 are internal routers NAT is enabled on Router R1.
The routing protocol that is enable between routers R1, R2, and R3 is RIPv2.
R1 sends default route into RIPv2 for internal routers to forward internet traffic to R1.
Server1 and Server2 are placed in VLAN 100 and 200 respectively, and dare still running router on stick configuration with router R2.
You have console access on R1, R2, R3, and L2SW1 devices.
Use only show commands to troubleshoot the issues.





















































Server1 and Server2 are unable to communicate with the rest of the network.
Your initial check with system administrators shows that IP address settings are correctly configured on the server side.
What could be an issue?
A. The VLAN encapsulation is misconfigured on the router subinterfaces.
B. The Router is missing subinterface configuration.
C. The Trunk is not configured on the L2SW1 switch.
D. The IP address is misconfigured on the primary router interface.
answer: A
Explanation:
Check the configuration of the interface that is connected to Server1 and Server2 on R2 with
"show running-config" command.

We see that subinterface E0/1.100 has been configured with VLAN 200 (via "encapsulation dot1Q 200" command) while Server1 belongs to VLAN 100. Therefore this configuration is not correct. It should be "encapsulation dot1Q 100" instead. The same thing for interface E0/1.200, it should be "encapsulation dot1Q 200" instead.

NEW QUESTION: 3
Referring to the exhibit, traffic is being sent from user1 to server 1 .The traffic is being classified using IP presentence into the default forwarding class expedited forwarding on

A. the traffic is serviced by the network control queue
B. the traffic is serviced by the expedited forwarding queues
C. the traffic is serviced by the assured forwarding queue
D. the traffic is serviced by the best effort queue
