21 What VLANs are allowed across a trunk when the range of allowed VLANs is set to the default value? All VLANs will be allowed across the trunk. Only VLAN 1 will be allowed across the trunk. Only the native VLAN will be allowed across the trunk. The switches will negotiate via VTP which VLANs to allow across the trunk. 22

Refer to the exhibit. Assuming the bridge priority values are set to default on all switches, which switch will be elected as the roo of the spanning tree topology? Cat-A Cat-B

Cat-C Cat-D 23 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 network 24

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 way 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 mes

Because the hub will temporarily block traffic from one of the hosts, that host will be allowed to transmit once the wire is cle 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. 25

Refer to the exhibit. RTB is configured for traditional inter-VLAN routing. RTB can ping computer A but cannot ping computer B. W possible cause of this failure? Port Fa0/11 is in the wrong VLAN.

31 A network administrator enables sticky learning on all access mode interfaces of a Catalyst switch, saves the configuration, then connects hosts to the switch. After the switch operates for several days, the administrator reboots the switch without saving the configuration. What is the result? All previously learned MAC addresses are lost. The switch reverts to non-sticky dynamic learning. Connected hosts are no longer able to communicate with the switch. Previously learned sticky addresses are retained in the switch configuration. 32

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. 33

Refer to the exhibit. What is the purpose of the configuration commands that are shown? to activate port Fa0/10 to make the port a member of VLAN 30 to activate port security on port Fa0/10 to add VLAN 30 to the trunk that is connected to port Fa0/10 34

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 originat 35

Refer to the exhibit. A network administrator enters the displayed commands to configure VLAN 30. What is the result of running commands? VLAN 30 will be added to S1, S2, and S3, but not to S4. VLAN 30 will be pruned from the VLAN database of S3. VLAN 30 will be added to the VLAN database of S3 but will not be propagated to S4, S2 or S1. VLAN 30 will not be added to the VLAN database of S3 and an error message will be displayed. 36 A network technician is evaluating the desirable features of both access and distribution layer switches. Which two features are to switches at these two layers? (Choose two.) QoS PoE port security link aggregation application based filtering 37 Which statement is accurate about fast-forward switching? The switch stores the first 64 bytes of the frame before forwarding. After reading the destination address, the switch immediately forwards a frame. The switch receives the complete frame and stores it in buffers before forwarding it.

The switch analyzes the frame for information about its destination. After confirming the integrity of the frame, the switch fo out the correct port. 38

Refer to the exhibit. Which password allows the administrator to enter the privileged exec mode? cisco1 cisco2 cisco3 cisco 39

41 A wireless access point can function as which type of shared medium, wired LAN device? hub switch router gateway 42

Refer to the exhibit. Which two facts can be confirmed by this output? (Choose two.) This switch shows no configuration revision errors. This switch has established two-way communication with the neighboring devices. This switch is configured to advertise its VLAN configuration to other VTP-enabled switches in the same VTP domain. This switch will drop all VTP advertisements that come from the switches that are configured in the same VTP domain.

This switch will cause no disruption in the VTP domain operations if the rest of the switches in the same VTP domain have configuration revision number. 43 Which parameter is associated with wireless authentication? shared key SSID ad hoc channel

44 Using the command copy tftp:backup.cfg startup-config, an administrator downloaded a saved configuration from a TFTP se

switch. Why does the administrator not detect any changes in the switch configuration after the download completes? The command should have been copy startup-config tftp:backup.cfg. A backup configuration from a TFTP server cannot be copied directly into the startup-config. The command copy running-config startup-config should be used to save the changes on the switch. Downloading to the startup-config requires the switch to be reloaded in order for the configuration to take effect. 45

Refer to the exhibit. Both switches are configured as displayed and the native VLAN is the default. Which statement is true abou frames traveling between host A and host B? They will travel untagged. They will be tagged with VLAN ID 1. They will be tagged with the trunk Port VLAN ID. They will be tagged with the highest VLAN ID.

46 Which service should be disabled on a Cisco switch or router to prevent packet sniffers from capturing information about the de SSH VTP CDP SNMP 47

Refer to the graphic. In the Wireless menu option of a Linksys integrated router, what does the Network Mode option Mixed mea The router supports encryption and authentication. The router supports both wired and wireless connections. The router supports 802.11b, 802.11g, and 802.11n devices. The router supports connectivity through infrared and radio frequencies. 48 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. 49

Refer to the exhibit. Router R-West and switch S-West1 are connected via a single ethernet cable between the router interface the switch interface fa0/1. The router and switch have been configured with the commands that are displayed in the exhibit. The

administrator enters the show interfaces trunk command and receives the output as shown. What is the cause of the "not-trun 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 es trunk. 50

Refer to the exhibit. The network administrator enters the configuration shown to allow both SSH and Telnet connections to the The Telnet connections fail. What is the most likely cause of this problem? The SSH version number is wrong. SSH has been configured on the wrong line. Telnet and SSH cannot be configured simultaneously.
