This may indeed be true, but until the LAN interface problems of the router areresolved, it is not an issue. If this was the only problem, then there would be no problemswith Host A trying to reach Host C or D.C. This choice is wrong because Host C can ping Host D so FA0/5 cannot be down.D, E. Choice D and E are wrong because Host A can Ping Host B it means that the switchCertkiller 1 and switch Certkiller 3 are both functioning properly and is turned on.QUESTION 209:Which of the following steps are necessary in order to add a new VLAN to theCertkiller switched network? (Select all that apply)A. Create the VLAN.B.
Name the VLAN.C. Configure an IP address for the VLAN.D. Add the desired ports to the new VLAN.E. Add the VLAN to the VTP domain.Answer: A, B, DExplanation:The following are the basic requirements for creating VLANs:* Creating the VLAN numbers and names* Configuring each port's assigned VLANIncorrect Answers:C. This is an optional feature, but not a necessary step for creating a VLAN.E. Adding any VLAN to a Virtual Trunking Protocol (VTP) domain may be desired in acomplex multi-switch and multi-VLAN network.
However, it is not a necessary step forcreating stand-alone VLANs on a single switch.Actualtests.com - The Power of Knowing640-802QUESTION 210:You need to create a new VLAN on your Catalyst switch. This VLAN is to be namedCertkiller . Which of the following need to be completed for the creation of thisnew VLAN? (Select all that apply)A. The Certkiller VLAN must be created.B. The desired ports must be added to the new Certkiller VLAN.C. The Certkiller VLAN must be added to all of the domains.D. The Certkiller VLAN must be named.E.
An IP address must be configured for the Certkiller VLAN.F. None of the above. VLAN creations are automatic.Answer: A, B, DExplanation:Creating a VLAN is done in 3 steps:1. Create the VLAN2. Name the VLAN3. Assign ports to the VLANFrom there, other features and functionality can be configured, but these are the onlysteps that are required for the addition of a VLAN.Incorrect Answers:C. The VLAN needs only to be added to a single switch, where it can act as a stand-aloneVLAN, or it can be transferred to other switches in the network through the use of theVTP protocol.E.
VLANs operate at layer 2, and although many are configured with a layer 3 IPaddress, it is not absolutely necessary to do this.QUESTION 211:What must the Certkiller network administrator do in order to successfullyconfigure VTP so that VLAN information can be propagated across the trunkbetween two switches named CK1 and CK2 ? (Select two answer choices)A. Set each end of the trunk link to IEEE 802.1Q encapsulation.B. Set the same VTP management domain name on both switches.C.
Set all ports on the two switched as access ports.D. Configure one of the two switches as a VTP server.E. Connect the two switches using a rollover cable.F. Use a router to forward VTP traffic between the VLANs.Answer: B, DExplanation:Actualtests.com - The Power of Knowing640-802All switches that need to share VLAN information via a trunk must use the same VTPdomain name, and a switch can only be in one domain at a time. This means that a switchcan only share VTP domain information with other switches if they're configured into thesame VTP domain. You can use a VTP domain if you have more than one switchconnected in a network, but if you've got all your switches in only one VLAN, you don'tneed to use VTP.
VTP information is sent between switches via a trunk port.Switches advertise VTP management domain information, as well as a configurationrevision number and all known VLANs with any specific parameters. There's alsosomething called VTP transparent mode, in it, you can configure switches to forwardVTP information through trunk ports, but not to accept information updates or updatetheir VTP databases. At least one of the switches will need to be configured as the VTPserver in order to pass the VLAN info.Incorrect Answers:A.
Although this is a valid option, it is not a requirement since using ISL as theencapsulation type is also a valid option.E. A rollover cable is not used between switches for any of the port types.F. Routers will be required for sending traffic from one VLAN to the other, but not toforward the actual VTP traffic.QUESTION 212:After connecting a PC to an available port on a switch, you find that the PC can notaccess any of the resources on the LAN.
No other PC's connected to the switchappear to be having any issues. What is the most likely cause for this problem?A. The router lacks a routing table entry for the new hostB. The host switch port is assigned to the incorrect VLANC. The host MAC address is incorrectly configuredD. A STP instance for the new host has not been initializedE. The switch does not have the MAC address hard coded in the CAM table.Answer: BExplanation:Virtual LANs break up broadcast domains in a layer-two switched internetwork.
If a hostis in a different VLAN then the network services it needs to use, the packets must gothrough a router. If routing does not take place, the PC will be unable to communicatewith any other devices not in the same VLAN. Answer B is the best answer for thisquestion.Incorrect Answers:A. The PC is unable to communicate with other LAN users. No router needs to even beinstalled for this to work.C, E. The MAC address of the PC does not need to be entered manually into the switch.Actualtests.com - The Power of Knowing640-802The switch will dynamically learn of the MAC address of the PC.D.
The STP algorithm does not need to have any end host information added in order forit to work.QUESTION 213:The Certkiller network administrator needs to verify that switch interface 0/5 hasbeen assigned to the Marketing VLA.N. Which command will accomplish this task?A. Show vlanB. Show mac-address-tableC. Show vtp statusD. show spanning-tree rootE. show ip interface briefF. None of the aboveAnswer: AExplanation:The "show vlan" command displays the configured vlan name and ID as well as the portsthat belong to each VLAN, etc. By default all ports belongs to VLAN 1Note: You can also use: show vlan brief, show vlan ID where ID is the VLAN ID.QUESTION 214:Exhibit:Please study the exhibit shown above carefully.
The Certkiller switch that generatedthis output has 24 ports. Why are some of the ports missing from VLAN1?A. The missing ports are in VLAN 86.B. The missing ports are administratively disabled.C. The missing ports are not participating in spanning tree.D. The missing ports are configured as trunk ports.Actualtests.com - The Power of Knowing640-802E. The missing ports have a status problem such as a speed or duplex mismatch.F. None of the aboveAnswer: DExplanation:The show vlan command displays the VLAN information and ports in all VLANs.
Thiscommand displays only the ports in access mode. The missing ports must be configuredas trunks.QUESTION 215:A new trunk has been configured on a switch in the Certkiller LAN. By default,which VLANs are allowed over this trunk link?A. No VLANsB. Only the VLANs that are specified when creating the trunkC. Only VLANs 1-64D. All VLANsE. All VLAN's except VLAN 1F. None of the aboveAnswer: DExplanation:Trunk ports send and receive information from all VLANs by default, and if a frame isuntagged, it's sent to the management VLAN. This applies to the extended range VLANsas well.
But we can remove VLANs from the allowed list to prevent traffic from certainVLANs from traversing a trunked link.Here is example:RouterA(config)#int f0/1RouterA(config-if)# switchport mode trunkRouterA(config-if)#switchport trunk allowed vlan VLANIDRouterA(config-if)#switchport trunk allowed vlan remove VLANIDQUESTION 216:The Certkiller network administrator has just issued the "switchport trunk nativevlan 998" command on switch CK2 . What is the function of this command?A.
It designates VLAN 998 as the default for all unknown tagged trafficB. It designates VLAN 998 for untagged trafficC. It blocks VLAN 998 traffic from passing on the trunkD. It creates a VLAN 998 interfaceActualtests.com - The Power of Knowing640-802E.
None of the aboveAnswer: BExplanation:Native VLAN is the VLAN that you configure on the Catalyst interface before youconfigure the trunking on that interface. By default, all interfaces are in VLAN 1.Therefore, VLAN 1 is the native VLAN that you can change. On an 802.1Q trunk, allVLAN packets except the native VLAN are tagged. You must configure the nativeVLAN in the same way on each side of the trunk. Then, the router or switch canrecognize to which VLAN a frame belongs when the router or switch receives a framewith no tag.To configure the native VLAN use the following command.Cat2950(config-if)# switchport trunk native vlan 10QUESTION 217:Part of the Certkiller switched LAN is shown in the following exhibit:As a network associate for Certkiller , you need to configure the switches and routerin the graphic shown above so that the hosts in VLAN3 and VLAN4 cancommunicate with the enterprise server ( Certkiller E) in VLAN2.
To accomplish this,which two Ethernet segments would need to be configured as trunk links? (Choosetwo)A. AB. BC. CD. DE. EF. FAnswer: C, FExplanation:Actualtests.com - The Power of Knowing640-802Layer 3 routing is needed to implement communication between VLANs, so a trunk linkis configured between Router and Certkiller 2. Both Certkiller 1 and Certkiller 2 ownVLAN3 and VLAN4 members, so a trunk link is configured between Certkiller 1 andCertkiller 2.QUESTION 218:You are bringing up a new Certkiller switch, and wish to connect it via a trunk toanother switch from a different vendor, which uses the IEEE standard for thetrunking method. When setting the encapsulation type on the trunk, what shouldyou configure on the Cisco switch?A. Switch(config)# switchport trunk encapsulation islB. Switch(config)# switchport trunk encapsulation ietfC.
Switch(config-if)# switchport trunk encapsulation islD. Switch(config-if)# switchport trunk encapsulation ietfE. Switch(config-if)# switchport trunk encapsulation dot1qAnswer: EExplanation:The only real choices for setting up switching trunks are ISL and 802.1Q. ISL is Ciscoproprietary, while 802.1Q uses the IEEE defined standard for trunking between switches.To configure the 802.1Q standard, the keyword "dot1q" is used in Cisco switches.Incorrect Answers:A, B, D.
