you to use the CLI of Sw AC3 to answer five multiple choice questions This does not require any configuration To answer the multiple choice questions click on the numbered boxes in the right panel There are five multiple choice questions with this task Be sure to answer all five questions before leaving this item Click on the exhibit for larger picture Http bbs 56CTO com 中国思科华为 3COM 网络技术发布 中国思科华为 3COM 网络技术发布 Important The VTP simlet has a pool of 10 question Test may have only 5 Questions for VTP SIM some very usefull commands to answer this simlet show cdp neighbor show cdp neighbor detail show interface trunk or switchport show mac address table show spanning tree show vlan show vtp status show run The pool of 10 questions are discussed here starting with the 4 questions in the above picture Question 1 What interface did Sw AC3 associate with source MAC address 0010 5a0c ffba Answer Fa 0 8 As per the picture above To find out the associate interface number for a given mac address on the switch use the show mac address table command and search for the mac address 0010 5a0c ffba and its associated interface number Http bbs 56CTO com 中国思科华为 3COM 网络技术发布 中国思科华为 3COM 网络技术发布 Question 2 what ports on Sw AC3 are operating has trunks choose two Answer Fa 0 9 and Fa 0 12 As per the picture above To find out the ports operating has trunks on a switch Use the show interface trunk command this will display all the trunk ports configured on switch or Use the show interface switchport command and check the output of the command for operational mode type trunk for each and every interface Question 3 What kind of router is VLAN R1 Answer 2611 as per picture above To know details of directly connected Neighbor use the following command on the switch show cdp neighbors command this output gives the following details about its neighbors Device ID Local Interface Holdtme Capability Platform Port ID To know what kind of router is VLAN R1 we need to identify its platform details from above command output Question 4 Which switch is the root bridge for VLAN 1 Answer Sw AC3 As per the question above in picture Http bbs 56CTO com 中国思科华为 3COM 网络技术发布 中国思科华为 3COM 网络技术发布 Step1 Use the Show spanning tree vlan 1 command this output provide the mac address of the root bridge Step2 now use the show mac address table command this output associates the mac address to a interface number Step3 use the command show cdp neighbors this output will give us the local interface associated with the hostname Device ID Question 5 Out of which port on switch Sw Ac3 would a frame containing an IP packet with destination address that is not on a local LAN be forwarded Answer To forward any packet with destination address other then the subnet network of the switch the switch usually forwards this IP packets to the layer 3 device example router connected to it Step1 Find the default gateway Router or layer 3 device configured on the switch use the Show run command to view the IP address used to configure default gateway on the switch Step2 Look for the router VLAN R1 after using the show cdp neighbor detail command Sample output of show cdp neighbor detail command for better understanding the output details Device ID C2950 1 Entry address es Platform Cisco WS C2950T 24 Capabilities Switch IGMP Interface FastEthernet0 0 Port ID outgoing port FastEthernet0 15 Holdtime 139 sec Two things to notice from above output Interface FastEthernet0 0 this statement provides that the neighbor c2950 1 is connected to fa 0 0 on the c3660 2 local switch Port ID outgoing port FastEthernet0 15 this explains that neighbor c2950 1 uses fa 0 15 port to reach c3660 2 switch Http bbs 56CTO com 中国思科华为 3COM 网络技术发布 中国思科华为 3COM 网络技术发布 FOR OUR QUESTION WE SHOULD LOOK FOR THE ROUTER VLAN R1 corresponding details and to which port it is connected on local switch Sw Ac3 Step3 The port number to which the routerVLAN R1 is connected on switch Sw Ac3 is used to forward the packets with destination address that is not on a local LAN Question 6 What address should be configured as the default gateway for the host connected to interface fa 0 4 of SW Ac3 Answer Step1 Find the details of the VLAN assigned to interface fa 0 4 by using the show vlan command on Sw Ac3 The above exhibit question has fa 0 4 configured has VLAN1 based on the output from show vlan command Step2 From the exhibit question we know that VLAN1 is configured on router using sub interface fa 0 0 1 with IP address 192 168 1 254 24 Step3 192 168 1 254 should be configure as default gateway address for the host connected to fa 0 4 on switch Because VLAN1 corresponds to fa 0 4 on Sw Ac3 and host connected to fa 0 4 will be member of vlan1 Question 7 Out of which ports will frame with source mac address 0015 5A0Cc A086 and destination mac address 000A 8A47 0612 be forwarded Answer Step1 Use Show mac address table command on the switch The output of a show mac address table provides the mapping of mac address with port numbers Search the output for the two mac addresses provided in the question and select the destination mac address corresponding port number for correct answers Step2 If you do not find the above destination mac address in SHOW MAC ADDRESS TABLE output then the frame will be broadcast or flooded to all ports all Http bbs 56CTO com 中国思科华为 3COM 网络技术发布
