Refer to the exhibit. The VTP domain has been configured as shown in the exhibit. None of the configured VLANs on SW1 and SW2 are present on SW3. What should be done to remedy the problem?
Reconfigure switches SW2 and SW3 in VTP transparent mode.
Reconfigure the VTP password to be consistent on all VTP switches.
Reconfigure all switches as VTP clients to synchronize the VLAN database information.Reconfigure the VTP server as a VTP client and then return to VTP server mode to reset the configuration revision number.
19 In setting up a wireless infrastructure network, which device is used to associate a client computer to the network?
an Ethernet switch
a wireless access point
another wireless computer
a hard-wired computer on the network20 Which configuration changes will increment the configuration revision number on the VTP server?
configuring trunk links on the VTP server
configuring or changing the VTP password
configuring or changing the VTP domain name
configuring or changing the VTP version number
configuring or deleting a VLAN or creating a VLAN name21
Refer to the exhibit. The switches have been configured as shown. The hosts that are connected to switch 101-2FL are not able to communicate with the hosts in their corresponding VLANs that are connected to switch 101-3FL. What should be done to fix the problem?
Configure port Fa0/2 on switch 101-3FL as a static trunk link.
Introduce a Layer 3 device or a switch with Layer 3 capability into the topology.
Utilize the switchport trunk allowed vlan all command on switch 101-3FL to permit the VLAN traffic.Apply IP addresses that are in the same subnet to the interfaces that are used to connect switches 101-2FL and 101-3FL.
22 Which statement correctly describes the spanning-tree path cost?It is calculated based on the total number of switches connected in a loop.
It is calculated based on the utilization of all the switches along a given path.
It is calculated based on the bridge priority of the switches along a given path.It is calculated based on the sum of the port cost value, determined by link speed, for each switch port along a given path.
23 Which statement is correct about STP architecture?Spanning Tree Protocol will guarantee a loop free Layer 2 topology.
Spanning Tree Protocol guarantees the shortest path to destination networks.
The switch with the highest priority will be assigned the lowest BID in the root election.
The first step in the spanning-tree election process is to determine the root port.To select designated ports, the spanning-tree algorithm must determine the longest contiguous path from the root bridge.
24A wireless LAN access point will convert traffic between which two frame encapsulation types?
802.1 and 802.11
802.3 and 802.11
802.3 and 802.16
802.5 and 802.1625
Refer to the exhibit. RTB is configured for traditional inter-VLAN routing. RTB can ping computer A but cannot ping computer B. What is a possible cause of this failure?Port Fa0/11 is in the wrong VLAN.
RTB does not have an active routing protocol.
The IP address of computer B is in the wrong logical network.
Router interface Fa0/1 has the wrong trunk encapsulation type configured.26
Refer to the exhibit. Which statement is true regarding the information shown?Only one VLAN is currently configured to use the trunk links.
The switch negotiated trunk links for interfaces Fa0/1 and Gi0/1.
A Cisco proprietary protocol is in use for interfaces Fa0/1 and Gi0/1.
Interfaces Gi0/1 and Fa0/1 are allowed to carry data from multiple VLANs.
27
Refer to the exhibit. Router R1 is connected to a switch through a trunk. What two ways are indicative of how the router handles incoming VLAN traffic? (Choose two.)
Data from VLAN 20 is not being routed.
Incoming traffic with VLAN ID 1 is processed by interface Fa0/0.
Incoming traffic that has a VLAN ID of 10 is processed by subinterface Fa0/0.1.
VLAN traffic is processed on the subinterfaces even if Fa0/0 line protocol goes down.The router uses a unique MAC address on VLAN 10 and 20 by adding the 802.1Q VLAN ID to the hardware address.Traffic inbound on this router is processed by different subinterfaces depending on the VLAN from which the traffic originated.
28 What is the correct order in which the STP components are chosen?designated ports, nondesignated ports, root bridge, root ports
nondesignated ports, designated ports, root ports, root bridge
root bridge, root ports, designated ports, nondesignated ports
root ports, root bridge, nondesignated ports, designated ports29 A network technician is evaluating the desirable features of both access and distribution layer switches.
Which two features are common to switches at these two layers? (Choose two.)QoS
PoE
port security
link aggregation
application based filtering
30
Refer to the exhibit. After receiving a console notification on Switch2, the network administrator begins to troubleshoot the trunk link between Switch1 and Switch2. Which configuration change can be made to correct the problem with the trunk link?
Set the Fa0/1 interface on Switch2 to trunk mode.
Change the trunk encapsulation on Switch2 Fa0/1 to dot1q.
Change the native VLAN on Switch2 interface Fa0/1 to VLAN 100.
Change the access mode VLAN on Switch2 to the default VLAN 1.
31Why is it important that the network administrator consider the spanning-tree network diameter when choosing the root bridge?
The network diameter limitation is 9.
BPDUs may be discarded because of expiring timers.
The cabling distance between the switches is 100 meters.The network diameter must be set to the number of meters of the cable between the root bridge and its farthest connected switch.
32
Refer to the exhibit. Router R-West and switch S-West1 are connected via a single ethernet cable between the router interface fa0/0 and the switch interface fa0/1. The router and switch have been configured with the commands that are displayed in the exhibit. The network administrator enters the show interfaces trunk
command and receives the output as shown. What is the cause of the "not-trunking" status for switch port Fa0/1?
The trunk is established, but no VLANs have been configured to use it.
The router is missing the dynamic trunking protocol statements necessary to form a trunk.
Because the router does not support Dynamic Trunking Protocol, the trunk has not been established.The router, the switch, or both must be configured with the dynamic desirable option for Dynamic Trunking Protocol to establish a trunk.
33 After unpacking a new Linksys WRT300N wireless multifunction device, a user needs to change the default administrator password and make other configuration changes. What must the user do to access the device in order to make these changes?
Use a wireless client to associate with the WRT300N and then open a HyperTerminal session with the device.Establish a wired connection with the device and then reboot the attached computer to launch the configuration software.Establish a wired connection from a computer in the same IP subnet as the WRT300N and enter the default IP address of the device into a web browser on the computer.Modify the TCP/IP properties of the computer that is connected to the WRT300N so that the computer and the WRT300N exist on the same network. Then reboot the computer to establish a connection.
34
Refer to the exhibit. Both switches are configured with default bridge priority. Which port will act as the STP root port if all links are operating at the same bandwidth?

Refer to the exhibit. What three statements describe why Host1 and Host2 are unable to communicate? (Choose three.)
The switch ports are on different VLANs.
The switch IP address is on the wrong subnet.
The hosts are configured on different logical networks.
A router is required to forward traffic between Host1 and Host2.
The VLAN port assignments must be contiguous for each VLAN.
The host default gateway addresses must be on the same logical network.

After listening for the presence of a signal on the network media, hosts A and C transmit data at the same time. In what two ways do the hosts respond to this situation? (Choose two.)
The hosts transmit a jam signal to ensure that all hosts on the network are aware that a collision has occured.Because they are operating in full-duplex mode, the hosts resume listening for traffic in preparation for sending future messages.Because the hub will temporarily block traffic from one of the hosts, that host will be allowed to transmit once the wire is clear.Hosts A and C are assigned shorter backoff values to provide them priority to access the media for retransmission.After the backoff period of a host, the host checks to determine if the line is idle before retransmitting.
40 A network administrator is asked to connect four switches that are each configured with eight VLANs. Routers that have two FastEthernet ports each that support trunking are available.
