STAT ¡Ì FDUP UTIL 100 PORT 2 An old workstation has +been replaced with a new one. The workgroup switch is not learning the MAC +address of the new workstation. A network technician has verified that a static +MAC address is not configured on the attached switch port. Which commands can +the technician issue at the switch CLI to further troubleshoot the problem? +(Choose two.) Switch# show port security ¡Ì Switch# show version Switch# show +startup-config Switch# clear mac-address-table ¡Ì Switch# reload Switch# +delete flash:vlan.dat 3 Which files must be deleted in order to completely +remove an existing configuration from a Cisco 2950 switch? (Choose two.) +flash:c2950-c3h2s-mz.120-5-3.WC.1.bin running-config VLAN.bin startup-config +¡Ì c2950-c3h2s-mz.120-5-3.WC.1.dat VLAN.dat ¡Ì 4 Which type of cable is +used to connect to the console port on a switch? a crossover cable a patch +cable a rollover cable ¡Ì a straight-thru cable 5 A workstation on a switched +Ethernet LAN is to be upgraded with a new Fast Ethernet NIC. What should be +done to ensure that the workstation will be able to gain access to the network? +delete the configuration file from the switch and reload IOS deactivate port +security on the port until the new host has connected to the network ¡Ì +remove the host from the the management VLAN until the new MAC address has been +learned by the switch delete the VLAN.dat file from flash and reboot the switch +configure the attached switch port for full-duplex mode 6 What does an amber +system LED indicate about a Catalyst switch? (Choose two.) The switch has +power. ¡Ì The switch has passed POST and is working properly. The switch has +failed POST. ¡Ì The switch is going through POST. The switch is in the +process of initializing its ports. 7 What must be done in order to initiate the +password recovery procedure on a Catalyst 2900 series switch? Rename the Flash +file. Enter the setup program by deleting the switch configuration file and +rebooting the switch. Hold down the MODE button during switch startup. ¡Ì +Wait for the STAT LED to turn green while holding down the Break key. Hold down +the Ctrl-Break keys during switch startup. 8 From which switch command mode can +the configure command be used? config user EXEC privileged EXEC ¡Ì command +EXEC flash 9 Which form of switch command-line help displays a list of keywords +and arguments that are associated with a command entered at the CLI prompt? CLI +help command syntax help ¡Ì keyword help word help 10 What is the name of the +series of tests that execute every time a switch is powered on? RPS bootstrap +power-on self test ¡Ì system STAT pre-boot 11 A new policy for disaster +recovery requires copying all critical network configurations and operating +systems to a backup server that will be stored offsite. Which command will +create a backup of the switch IOS image on the server? Switch# copy tftp NVRAM +Switch# copy running-config tftp Switch# copy flash tftp ¡Ì Switch# copy IOS +tftp Switch# copy tftp flash Switch# copy NVRAM tftp 12 The network +administrator shown in the graphic is connected to Switch3 over Ethernet. The +administrator needs to verify configuration settings on the newly installed +Switch2. What conditions need to be met in order for the administrator to +access Switch2 with a web browser? (Choose three.) complete IP addressing +configured on Switch2 ¡Ì Privileged EXEC mode password configured on Switch2 +hostname configured on Switch2 management VLAN password set HTTP service +activated on Switch2 ¡Ì adminstrator host connectivity to the Switch2 +management VLAN ¡Ì 13 Which protocol is used to copy a new IOS image to a +Catalyst switch during the upgrade procedure? HTTP Telnet TFTP ¡Ì TTY IOS 14 +What color is the System LED if the switch fails the POST? amber ¡Ì green red +white off 15 Although the backup configuration file on a Catalyst 2950 switch +has been erased, it is found that VLANs are still configured in the switch. +What must be done to clear the configured VLANs? The vlan.dat file must be +erased and the switch reloaded. ¡Ì The switch flash memory must be purged and +the switch rebooted. The vlan.cfg file must be renamed and IOS restarted. Each +VLAN needs to be deleted individually and the configuration saved. The switch +needs to be restarted, because the old running configuration is still in +memory. 16 How can a switch be configured to prevent unauthorized hosts from +access to a network? (Choose three.) Host MAC addresses can be statically +assigned to each switch port. ¡Ì Layer 2 access control lists can be used to +prevent unauthorized network access. Unused ports can be shutdown. ¡Ì +Passwords and usernames can be set for each Ethernet switch port. Unused switch +ports can be assigned to the management VLAN. Port security can be activated to +allow only the host with the first MAC address learned on a port to access the +network. ¡Ì 17 Which switch command mode should always be password protected? +User Command User Config User EXEC User Privileged Privileged EXEC ¡Ì 18 +Which options are available when setting the action to be taken when a port +security violation occurs on a switch port? (Choose two.) log-allow return trap +shutdown ¡Ì poison 19 Which commands can be used to change from Global +Configuration mode to Privileged EXEC mode? (Choose three.) Ctrl+z ¡Ì disable +end ¡Ì exit ¡Ì logout 20 What are the recommended HyperTerminal +configuration settings for establishing a console session between a switch +console port and PC COM port? (Choose three.) 9600 bits per second ¡Ì 192000 +bits per second hardware flow control¡Ì flow control Xon/Xoff even parity no +parity ¡Ì 21 Which methods can be used to perform the initial configuration +of a new switch? (Choose two.) copy a configuration from a FTP server type +commands manually after entering the Privileged EXEC mode ¡Ì enter the System +Configuration dialog ¡Ì Telnet to a local server to copy a configuration file +connect to the switch using a web browser 22 An administrator is using the +switch help facility to find the command elements available to the configure +command. What would the user type at the command prompt to display the next set +of arguments available in the syntax for this command? Switch# c? Switch# c ? +Switch# configure? Switch# configure ? ¡Ì 23 How long will a host MAC address +remain in the address table of a switch after the host has been turned off or +moved to another device? 30 seconds 180 seconds ¡Ì 300 seconds 30 minutes 24 +After powering up a switch, the network technician notices that the system LED +is amber. What can the technician assume? (Choose two.) The switch is +negotiating full or half-duplex mode. The switch has completed negotiating 10 +or 100 Mbps speed. The POST has failed. ¡Ì The boot sequence is in process. A +fatal error has occurred. ¡Ì The switch is operating properly and is ready +for service. 25 A group of hosts has been connected to a new Fast Ethernet +switch. Which of the following statements describe this newly created LAN, if +the new switch has not yet been configured? (Choose three.) The hosts will +negotiate 10 Mbps or 100 Mbps bandwidth with the switch, as required by their +NICs. ¡Ì The hosts will be in separate broadcast domains. All of the hosts +will be in the same VLAN. ¡Ì Hosts with 10 Mbps NICs will be unable to +communicate with the network. All of the hosts should be able to send and +receive ARP messages from each other. ¡Ì All of the hosts connected by +Ethernet can manage the switch over Telnet or HTTP. +(http://www.vreal.biz/Cet2615/exams/3.6.txt) |
