What does a client mode switch in a VTP management domain do whenit receives a summary advertisement with a revision number higher than itscurrent revision number?It suspends forwarding until a subset advertisement update arrives.It issues an advertisement request for new VLAN information.It increments the revision number and forwards it to other switches.It deletes the VLANs not included in the summary advertisement.It issues summary advertisements to advise other switches of status changes.14.
Refer to the exhibit. All switches in the network participate in the sameVTP domain. What happens when the new switch SW2 with a defaultconfiguration and revision number of 0 is inserted in the existing VTPdomain Lab_Network?The switch operates as a VTP client.The switch operates in VTP transparent mode.The switch operates as a VTP server and deletes the existing VLAN configuration inthe domain.The switch operates as a VTP server, but does not impact the existing VLANconfiguration in the domain.The switch operates as a VTP server in the default VTP domain and does not affectthe configuration in the existing VTP domain.15.
What are two features of VTP client mode operation? (Choose two.)unable to add VLANscan add VLANs of local significanceforward broadcasts out all ports with no respect to VLAN informationcan only pass VLAN management information without adopting changescan forward VLAN information to other switches in the same VTP domain16. Refer to the exhibit. S2 was previously used in a lab environment andhas been added to the production network in server mode. The lab andproduction networks use the same VTP domain name, so the networkadministrator made no configuration changes to S2 before adding it to theproduction network.
The lab domain has a higher revision number. After S2was added to the production network, many computers lost networkconnectivity. What will solve the problem?Reset the revision number on S2 with either the delete VTP command or by changingthe domain name and then changing it back.Re-enter all appropriate VLANs, except VLAN 1, manually on Switch1 so that theypropagate throughout the network.*Change S1 to transparent VTP mode to reclaim all VLANs in vlan.dat and changeback to server mode.Change S2 to client mode so the VLANs will automatically propagate.17. A network administrator is replacing a failed switch with a switch thatwas previously on the network.
What precautionary step should theadministrator take on the replacement switch to avoid incorrect VLANinformation from propagating through the network?Enable VTP pruning.Change the VTP domain name.Change the VTP mode to client.Change all the interfaces on the switch to access ports.18. Refer to the exhibit. Switch1 is not participating in the VTPmanagement process with the other switches that are shown in the exhibit.What are two possible explanations for this? (Choose two.)Switch1 is in client mode.Switch2 is in server mode.Стр. 9 из 1701.04.2009 0:46CISCO CCNA Certifications: CCNA 3 UPDATEDfile:///D:/botalka/%D1%81%D0%B8%D1%81%D1%8C%D0%BA...Switch2 is in transparent mode.Switch1 is in a different management domain.Switch1 has end devices that are connected to the ports.Switch1 is using VTP version 1, and Switch2 is using VTP version 2.19.
Refer to the exhibit. All switches in the VTP domain are new. SwitchSW1 is configured as a VTP server, switches SW2 and SW4 are configuredas VTP clients, and switch SW3 is configured in VTP transparent mode.Which switch or switches receive VTP updates and synchronize their VLANconfiguration based on those updates?All switches receive updates and synchronize VLAN information.Only switch SW2 receives updates and synchronizes VLAN information.Only switches SW3 and SW4 receive updates and synchronize VLAN information.SW3 and SW4 receive updates, but only switch SW4 synchronizes VLAN information.20. Which statement is true when VTP is configured on a switched networkthat incorporates VLANs?VTP is only compatible with the 802.1Q standard.VTP adds to the complexity of managing a switched network.VTP allows a switch to be configured to belong to more than one VTP domain.VTP dynamically communicates VLAN changes to all switches in the same VTPdomain.comments (0)TOP05:31CCNA 3:Module 3POSTED BY ADMINOptions With Highlight Colours are Correct Answer1.
What statement about the 802.1q trunking protocol is true?802.1q is Cisco proprietary.802.1q frames are mapped to VLANs by MAC address.802.1q does NOT require the FCS of the original frame to be recalculated.802.1q will not perform operations on frames that are forwarded out access ports.2. Which two statements describe the benefits of VLANs? (Choose two.)VLANs improve network performance by regulating flow control and window size.VLANs enable switches to route packets to remote networks via VLAN ID filtering.VLANs reduce network cost by reducing the number of physical ports required onswitches.VLANs improve network security by isolating users that have access to sensitive dataand applications.VLANs divide a network into smaller logical networks, resulting in lower susceptibility tobroadcast storms.3.
What are two characteristics of VLAN1 in a default switch configuration? (Choose two.)VLAN1 should renamed.VLAN 1 is the management VLAN.All switch ports are members of VLAN1.Only switch port 0/1 is assigned to VLAN1.Links between switches must be members of VLAN1.4. Refer to the exhibit.
SW1 and SW2 are new switches being installed in the topologyshown in the exhibit. Interface Fa0/1 on switch SW1 has been configured with trunkmode “on”. Which statement is true about forming a trunk link between the switches SW1and SW2?Interface Fa0/2 on switch SW2 will negotiate to become a trunk link if it supports DTP.Interface Fa0/2 on switch SW2 can only become a trunk link if statically configured as atrunk.Interface Fa0/1 converts the neighboring link on the adjacent switch into a trunk link ifthe neighboring interface is configured in nonegotiate mode.Interface Fa0/1 converts the neighboring link on the adjacent switch into a trunk linkautomatically with no consideration of the configuration on the neighboring interface.5.
Refer to the exhibit. Computer 1 sends a frame to computer 4. On which links alongthe path between computer 1 and computer 4 will a VLAN ID tag be included with theframe?AA, BA, B, D, GA, D, FC, EC, E, F6. The network administrator wants to separate hosts in Building A into two VLANsnumbered 20 and 30. Which two statements are true concerning VLAN configuration?(Choose two.)The VLANs may be named.VLAN information is saved in the startup configuration.Non-default VLANs created manually must use the extended range VLAN numbers.The network administrator may create the VLANs in either global configuration mode orVLAN database mode.Both VLANs may be named BUILDING_A to distinguish them from other VLANs inСтр.

Which two conclusions can be drawn regarding the switch thatproduced the output shown? (Choose two.)The network administrator configured VLANs 1002-1005.The VLANs are in the active state and are in the process of negotiating configurationparameters.A FDDI trunk has been configured on this switch.The command switchport access vlan 20 was entered in interface configuration modefor Fast Ethernet interface 0/1.Devices attached to ports fa0/5 through fa0/8 cannot communicate with devicesattached to ports fa0/9 through fa0/12 without the use of a Layer 3 device.8. What happens to the member ports of a VLAN when the VLAN is deleted?The ports cannot communicate with other ports.The ports default back to the management VLAN.The ports automatically become a part of VLAN1.The ports remain a part of that VLAN until the switch is rebooted.
They then becomemembers of the management VLAN.9. A network administrator is removing several VLANs from a switch. When theadministrator enters the no vlan 1 command, an error is received. Why did thiscommand generate an error?VLAN 1 can never be deleted.VLAN 1 can only be deleted by deleting the vlan.dat file.VLAN 1 can not be deleted until all ports have been removed from it.VLAN 1 can not be deleted until another VLAN has been assigned its responsibilities.10.
What is the effect of the switchport mode dynamic desirable command?DTP cannot negotiate the trunk since the native VLAN is not the default VLAN.The remote connected interface cannot negotiate a trunk unless it is also configured asdynamic desirable.The connected devices dynamically determine when data for multiple VLANs must betransmitted across the link and bring the trunk up as needed.A trunk link is formed if the remote connected device is configured with the switchportmode dynamic auto or switchport mode trunk commands.11.
Refer to the exhibit. The exhibited configurations do not allow the switches to form atrunk. What is the most likely cause of this problem?Cisco switches only support the ISL trunking protocol.The trunk cannot be negotiated with both ends set to auto.By default, Switch1 will only allow VLAN 5 across the link.A common native VLAN should have been configured on the switches.12. Switch port fa0/1 was manually configured as a trunk, but now it will be used toconnect a host to the network. How should the network administrator reconfigure switchport Fa0/1?Disable DTP.Delete any VLANs currently being trunked through port Fa0/1.Administratively shut down and re-enable the interface to return it to default.Enter the switchport mode access command in interface configuration mode.13. Refer to the exhibit.
Computer B is unable to communicate with computer D. What isthe most likely cause of this problem?The link between the switches is up but not trunked.VLAN 3 is not an allowed VLAN to enter the trunk between the switches.The router is not properly configured to route traffic between the VLANs.Computer D does not have a proper address for the VLAN 3 address space.14. Refer to the exhibit. The network administrator has just added VLAN 50 to Switch1 andSwitch2 and assigned hosts on the IP addresses of the VLAN in the 10.1.50.0/24 subnetrange. Computer A can communicate with computer B, but not with computer C orcomputer D.
