Drag each network plane on the left to the appropriate troubleshooting task on the right. Each plane may be used once. more than one, or not at all options:DATA PLANE, CONTROL PLANE, MANAGEMENT PLANE, DATA PLANE. 1) Determine how the traffic move from one to the other 2)Determine whether the VLANs have been configured on each switch 3)Examine the forwarding logic on each device 4)Use SNMP to monitor network switches 5) Isolate filtering and port security problems

1) Control plane 2) Data plane 3) Management plane 4) Data plane

You have three switches configured as shown in the Exhibit. For each port, identify the port role and status after convergence by matching the port states on the left with the ports on the graphic. (port states on the left can be used once, more than once, or not at all

A Gi0/1 = Altn BLK A Gi0/2 = Root FWD B Gi0/1 = Desg FWD B Gi0/2 = Desg FWD C Gi0/1 = Desg FWD C Gi0/2 = Root FWD

You have just connected four switches as shown in the Exhibit. Assuming the default switch configuration, how can your force Switch C to become a root bridge?

B

You have a small network as shown in the exhibit. You are troubleshooting connectivity issues at Wrk 1. From Wrk1 you are able to ping hosts Wrk2 and Wrk3. A ping to any host in the main office fails. From Wrk 2, you can ping any host in the branch office, but cannot ping any host in the main office. What is the most likely cause of the problem? (select two)

Bad cable between the switch and the SFO router, Fa0/234 on the switch is bad

You have two switches connected as shown int the exhibit. You would like to configure rapid spanning tree on switch A. On which ports would you use the portfast feature?

Fa0/1 and Fa0/2

Which statements accurately describe the port states of both bridges and switches? (select two)

In the learning state, the MAC address table can be populated but frames are not forwarded Ports in a blocked state receives BPDUs

What problem does the spanning Tree Protocol prevent?

It prevents message loop from developing when switch or bridge is connected to the same location more than one

You have entered the following command to enable dynamic trunking configuration: Switch(config-if)# switchport mode dynamic desirable. If the switch interface is not connected to another switch, how will it function?

It will communicate as a normal port

Switches running the STA are in the processed of exchanging BPDUs and defining their roles. In what state are the switches

Listening

You have been using PVST+ on your Cisco switches. You'd like to start using rapid spanning tree instead. Which of the following would you do? (select two)

On each switch, configure the mode with the spanning-tree rapid-pvst comand, On each switch, use no spanning-tree portfast

You are verifying the configuration of spanning tree on a switch. you run the show spanning- tree command on switch A and see the following output. What is the spanning tree mode for VLAN 1?

Rapid PVST +

You are configuring two catalyst 2960 switches with redundant connections. To reduce spanning tree convergence times, you should configure the switches to actively negotiate an EtherChannel using LACP channel group 4. Which command would you use for each redundant link?

Switch(config-if)#channel-group 4 mode active

You are configuring two Catalyst 3550 switches with redundant connections. to increase available traffic bandwidth between the switches, you should configure the switches to actively negotiate an EtherChannel using PAgP channel group 5. Which command would you use for each redundant link.

Switch(config-if)#channel-group 5 mode desirable

Which command disables the trunking configuration on a switch interface?

Switch(config-if)#switch mode access

You are verifying the configuration of the spanning tree on a switch. You run the show spanning-tree command on switch A and see the following output. What can you tell from this command output (Select two)

The MAC address for the switch A is 000e.8411.68c0 The root port on switch A is Gi0/2

You are verifying the configuration of spanning tree on a switch. you run the show spanning-tree command on switch A and see the following output (refer to picture). Why isn't this switch the root bridge.

The VLAN number has been added to the configured bridge priority

What is the effect of using the channel-group 2 mode passive interface configuration command? (select two)

The command configures the interface in a passive negotiating state and forms an EtherChannel if the port receives LACP packets

You have three switches configured as shown in the Exhibit. How could you guarantee that Fa0/1 on switch B is in the blocking state following STP convergence?

configure Fa0/1 on switch B with a higher cost value

You have three switches configured as shown in the exhibit. How could you guarantee that switch C becomes the root bridge?

configure switch C with a lower priority value

You have enter the following command to enable dynamic trunking configuring: Switch(config-if)#switchport mode dynamic desirable If the switch interface is connected to another switch, what will it attempt to do?

neogotiate a link using the desired trunking protocol

You need to configure spanning tree on a Cisco 2960 switch. You'd like to use a spanning tree protocol that uses the 802.1w standards. You'd like to take advantage of fast convergence when the trunk link goes down and fast transition to forwarding state for edge links. Which commands will be part of your configuration. (select two)

switch(config)#spanning-tree mode rapid-pvst, switch(config)#spanning-tree portfast
