These are not valid VTP modes.D. Client mode merely accepts changes made by the switch that is connected and inSERVER mode.QUESTION 241:Refer to the following output shown on router Certkiller 2:The "show vtp status" command is executed on the Certkiller 2 switch as shownabove. Based on this information, which statement is true for this switch?A. The VLAN database is updated when VTP information is received from otherswitches.Actualtests.com - The Power of Knowing640-802B.
The configuration revision number increments each time the VLAN database isupdated.C. The switch forwards its VLAN database to other switches in the ICND VTP domain.D. The switch forwards VTP updates that are sent by other switches in the ICND domain.E. None of the above.Answer: DExplanation:Switches in transparent mode don't participate in the VTP domain or share its VLANdatabase, but they'll still forward VTP advertisements through any configured trunk links.QUESTION 242:What are two results of entering the CKSwitch(config)# vtp mode client commandon a Catalyst switch in the Certkiller LAN? (Choose two.)A.
The switch will ignore VTP summary advertisementsB. The switch will forward VTP summary advertisementsC. The switch will process VTP summary advertisementsD. The switch will originate VTP summary advertisementsE. The switch will create, modify and delete VLANs for the entire VTP domainAnswer: B, CExplanation :Server mode-VTP servers have full control over VLAN creation and modification fortheir domains. All VTP information is advertised to other switches in the domain, whileall received VTP information is synchronized with the other switches.
By default, aswitch is in VTP server mode. Note that each VTP domain must have at least one serverso that VLANs can be created, modified, or deleted, and VLAN information can bepropagated.Client mode-VTP clients do not allow the administrator to create, change, or delete anyVLANs. Instead, they listen to VTP advertisements from other switches and modify theirVLAN configurations accordingly. In effect, this is a passive listening mode. ReceivedVTP information is forwarded out trunk links to neighboring switches in the domain, sothe switch also acts as a VTP relay.Transparent mode-VTP transparent switches do not participate in VTP.
While intransparent mode, a switch does not advertise its own VLAN configuration, and a switchdoes not synchronize its VLAN database with received advertisements. In VTP version 1,a transparent-mode switch does not even relay VTP information it receives to otherswitches, unless its VTP domain names and VTP version numbers match those of theother switches. In VTP version 2, transparent switches do forward received VTPadvertisements out of their trunk ports, acting as VTP relays. This occurs regardless ofthe VTP domain name setting.Actualtests.com - The Power of Knowing640-802QUESTION 243:Exhibit:Study the Exhibit carefully.
Switch Certkiller A sends a VTP advertisement andSwitch Certkiller B receives it. Which statement accurately describes how SwitchCertkiller B will respond?A. Switch Certkiller B will add 2 VLANs to its VLAN database and change theconfiguration revision number to 232B. Switch Certkiller B will remove 2 VLANs from its VLAN database and change theconfiguration revision number to 232C. Switch Certkiller B will enable VTP pruning, add two VLANs, and increment theconfiguration revision number to 233D. Switch Certkiller B will ignore the VTP advertisementE.
None of the aboveAnswer: DExplanation: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. If you find yourself having problems with users adding switches toyour VTP domain, you can include passwords, but don't forget that every switch must beset up with the same password-this can get ugly.Switches detect the additional VLANs within a VTP advertisement and then prepare toreceive information on their trunk ports with the newly defined VLAN in tow.
Thisinformation would be VLAN ID, 802.10 SAID fields, or LANE information. Updates aresent out as revision numbers that are the notification plus 1. Any time a switch sees ahigher revision number, it knows the information that it's receiving is more current, and itwill overwrite the current database with that new information.The Client synchronizes with the vtp server on every 5 minutes, if revision number isupdated then client copy the configuration.Actualtests.com - The Power of Knowing640-802The client has a revision number of 234, but would receive an update number of 232from the VTP server.QUESTION 244:Given the output of the London switch displayed in the graphic below, what VTPfunctions will this switch perform?A. It will pass on information about the VTP configurationB.
VTP is disabled on this deviceC. It will learn and save VTP configuration in the running configuration but does notsave it to NVRAMD. It will create, change and delete VLANsE. None of the aboveAnswer: CExplanation:The 3 VTP Modes are:1. Server: By default, a Catalyst switch is in the VTP server mode and in the "nomanagement domain" state until the switch receives an advertisement for a domain over atrunk link or a VLAN management domain is configured. A switch that has been put inVTP server mode and had a domain name specified can create, modify, and deleteVLANs. VTP servers can also specify other configuration parameters such as VTPversion and VTP pruning for the entire VTP domain.
VTP information is stored inNVRAM.2. Client: The VTP client maintains a full list of all VLANs within the VTP domain, butit does not store the information in NVRAM. VTP clients behave the same way as VTPservers, but it is not possible to create, change, or delete VLANs on a VTP client. Anychanges made must be received from a VTP server advertisement.3. Transparent: VTP transparent switches do not participate in VTP. A VTP transparentswitch does not advertise its VLAN configuration, and does not synchronize its VLANconfiguration based on received advertisements.
However, in VTP Version 2, transparentswitches do forward VTP advertisements that the switches receive out their trunk ports.VLANs can be configured on a switch in the VTP transparent mode, but the informationis local to the switch (VLAN information is not propagated to other switches) and isstored in NVRAM.Actualtests.com - The Power of Knowing640-802As can be seen by the output above, this switch is running in VTP client mode, makingchoice C correct.QUESTION 245:Study the Exhibit below carefully:London#show vtpVTP Version: 2Configuration Revision: 0Maximum VLANs supported locally: 64Number of existing VLANs: 5VTP Operating Mode: ClientVTP Domain Name: LondonVTP Pruning Mode: DisabledVTP V2 Mode: DisabledVTP Traps Generation: DisabledBased on the information given above, what is the VTP function of this particularswitch?A.
Learn and save VTP configuration in the running configuration.B. Create and change VLANs.C. Forwards information about VTP configuration.D. VTP is disabled on this device.E. VTP is not saved to NVRAM.Answer: CExplanation:From the output this switch is operating merely as VTP client, so it basically does as theVTP server says, and passes on information about VTP configuration to the next switchin line.Incorrect Answers:A. This is incorrect because the function is redundant.B. This incorrect because the switch must be in server or transparent mode to create andchange VLANs.D. This is incorrect because if VTP would be disabled, it wouldn't appear on thecommand output.E.
If this were true, the VTP configuration information would not be displayed afterbeing powered on.QUESTION 246:Exhibit:Actualtests.com - The Power of Knowing640-802Study the Exhibit carefully. The network administrator has configured the switchesin the school network to use VTP. The switches are not sharing VLAN information.Which sequence of commands should be issued to correct this problem?A.
Offices(config)# vtp mode clientLabs(config)# vtp mode clientB. Offices(config)# vtp domain SchoolLabs(config)# vtp domain SchoolC. Offices(config)# vtp pruningLabs(config)# vtp pruningD. Offices(config)# vtp version 2Labs(config)# vtp version 2Answer: BExplanation:For switched to share vlan information, there VTP domain names must be same.
In theOutput shown, VTP domain name of LABS router is Labs and VTP domain name ofOffices router is Offices. As the domain names are different, they are unable tocommunicate with each other. In order to correct this problem, we have to change theirnames to a single common name.QUESTION 247:Two Certkiller switches are connected together as shown below:Actualtests.com - The Power of Knowing640-802Switches CK1 and CK2 have been configured with a trunked line that has beenverified as working correctly. However, VTP is not propagating VLANs from oneswitch to the other. Based on the command output shown, what is the problem?A.
The revision number is not the same on both switches.B. Only one switch can be in server mode.C. The VTP domain name is not correctly configured.D. VLANs have not been configured on the VTP server.E. The VTP pruning mode is not correctly configured.Answer: CExplanation:VTP messages are exchanged between switches within a common VTP domain. In theoutput shown, VTP domain name of switch CK1 is JAX and domain name of switch CK2is JAK. As the VTP domain names are different so these two switches will not exchangethe VTP Information.Reference: http://www.ciscopress.com/articles/article.asp?p=29803&seqNum=4&rl=1QUESTION 248:Actualtests.com - The Power of Knowing640-802Network topology exhibit:Certkiller 1 exhibit:Certkiller 2 exhibit:Certkiller 3 exhibit:Study the exhibits carefully.
You are told by your boss, Mrs. Certkiller, that theVLAN configuration of switch Certkiller 3 is not synchronized with the other parts ofthe network. She tells you that you need to find out why Certkiller 3 is not receivingVTP updates. What should you tell her?A. Certkiller 1 supports a greater number of VLANs than does switch Certkiller 3.B. Certkiller 2 is not relaying VTP advertisements to Certkiller 3.C. Certkiller 2 should be operating in VTP server or client mode to relay VTP updates.D. Certkiller 3 has fewer existing VLANs than does Certkiller 1.E.
Certkiller 3 should be operating in VTP mode to relay VTP updates.F. Certkiller 3 has a revision number higher than that being advertised.Answer: FExplanation:The configuration revision number is a 32-bit number that indicates the level of revisionfor a VTP packet. Each VTP device tracks the VTP configuration revision number that isassigned to it. Most of the VTP packets contain the VTP configuration revision numberof the sender.Actualtests.com - The Power of Knowing640-802This information is used in order to determine whether the received information is morerecent than the current version. Each time that you make a VLAN change in a VTPdevice, the configuration revision is incremented by one. In this case, Certkiller 3 isconfigured as a client but the revision number is higher than the other switches, so it willignore the updates.
