What is the most likely cause of this problem?There is a native VLAN mismatch.The link between Switch1 and Switch2 is up but not trunked.The router is not properly configured for inter-VLAN routing.VLAN 50 is not allowed to entering the trunk between Switch1 and Switch2.15. Refer to the exhibit.
Which statement is true concerning interface Fa0/5?The default native VLAN is being used.The trunking mode is set to auto.Trunking can occur with non-Cisco switches.VLAN information about the interface encapsulates the Ethernet frames.16. What statements describe how hosts on VLANs communicate?Hosts on different VLANs use VTP to negotiate a trunk.Hosts on different VLANs communicate through routers.Hosts on different VLANs should be in the same IP network.Hosts on different VLANs examine VLAN ID in the frame tagging to determine if theframe for their network.17.

What is a valid consideration for planning VLAN traffic across multiple switches?Configuring interswitch connections as trunks will cause all hosts on any VLAN to receivebroadcasts from the other VLANs.A trunk connection is affected by broadcast storms on any particular VLAN that iscarried by that trunk.Restricting trunk connections between switches to a single VLAN will improve efficiencyof port usage.Carrying all required VLANs on a single access port will ensure proper traffic separation.19.
Which two statements about the 802.1q trunking protocol are true? (Choose two.)802.1q is Cisco proprietary.802.1q frames are mapped to VLANs by MAC address.If 802.1q is used on a frame, the FCS must be recalculated.802.1q will not perform operations on frames that are forwarded out access ports.802.1q allows the encapsulation of the original frame to identify the VLAN from which aframe originated.20. What switch port modes will allow a switch to successfully form a trunking link if theneighboring switch port is in "dynamic desirable" mode?dynamic desirable modeon or dynamic desirable modeon, auto, or dynamic desirable modeon, auto, dynamic desirable, or nonegotiate mode21. Refer to the exhibit.
Company HR is adding PC4, a specialized applicationworkstation, to a new company office. The company will add a switch, S3, connectedvia a trunk link to S2, another switch. For security reasons the new PC will reside in the HRVLAN, VLAN 10. The new office will use the 172.17.11.0/24 subnet. After installation, theexisting PCs are unable to access shares on PC4. What is the likely cause?The switch to switch connection must be configured as an access port to permit accessto VLAN 10 on S3.The new PC is on a different subnet so Fa0/2 on S3 must be configured as a trunk port.PC4 must use the same subnet as the other HR VLAN PCs.A single VLAN cannot span multiple switches.22.
What must the network administrator do to remove Fast Ethernet port fa0/1 fromVLAN 2 and assign it to VLAN 3?Enter the no vlan 2 and the vlan 3 commands in global configuration mode.Enter the switchport access vlan 3 command in interface configuration mode.Enter the switchport trunk native vlan 3 command in interface configuration mode.Enter the no shutdown in interface configuration mode to return it to the defaultconfiguration and then configure the port for VLAN 3.comments (1)TOP05:29CCNA 3:Module 2POSTED BY ADMINOptions With Highlight Colours are Correct Answer1.
When a switch receives a frame and the source MAC address is not foundin the switching table, what action will be taken by the switch to processthe incoming frame?The switch will request that the sending node resend the frame.The switch will issue an ARP request to confirm that the source exists.The switch will map the source MAC address to the port on which it was received.The switch ends an acknowledgement frame to the source MAC of this incomingframe.2. Refer to the exhibit. How many collision domains are depicted in thenetwork?1246783. Refer to the exhibit. What action does SW1 take on a frame sent fromPC_A to PC_C if the MAC address table of SW1 is empty?SW1 drops the frame.SW1 floods the frame on all ports on SW1, except port Fa0/1.SW1 floods the frame on all ports on the switch, except Fa0/23 and Fa0/1.SW1 uses the CDP protocol to synchronize the MAC tables on both switches and thenforwards the frame to all ports on SW2.4.
If a network administrator enters these commands in globalconfiguration mode on a switch, what will be the result?Switch1(config-line)# line console 0Switch1(config-line)# password ciscoSwitch1(config-line)# loginto secure the console port with the password "cisco"to deny access to the console port by specifying 0 lines are availableСтр. 12 из 1701.04.2009 0:46CISCO CCNA Certifications: CCNA 3 UPDATEDfile:///D:/botalka/%D1%81%D0%B8%D1%81%D1%8C%D0%BA...to gain access to line configuration mode by supplying the required passwordto configure the privilege exec password that will be used for remote access5.
A network administrator uses the CLI to enter a command that requiresseveral parameters. The switch responds with "% Incomplete command".The administrator cannot remember the missing parameters. What can theadministrator do to get the parameter information?append ? to the last parameterappend a space and then ? to the last parameteruse Ctrl-P to show a parameter listuse the Tab key to show which options are available6.
Refer to the exhibit. The switch and the hub have default configurations,and the switch has built its CAM table. Which of the hosts will capture acopy of the frame when workstation A sends a unicast packet toworkstation C?workstation Cworkstations B and Cworkstations A, B, C, and the interfaces of the routerworkstations B, C, D, E, F, and interfaces of the router7. Which two statements are true regarding switch port security? (Choosetwo.)The three configurable violation modes all log violations via SNMP.Dynamically learned secure MAC addresses are lost when the switch reboots.The three configurable violation modes all require user intervention to re-enableports.After entering the sticky parameter, only MAC addresses subsequently learned areconverted to secure MAC addresses.If fewer than the maximum number of MAC addresses for a port are configuredstatically, dynamically learned addresses are added to CAM until the maximumnumber is reached.8.
Refer to the exhibit. The exhibit shows partial output of the showrunning-config command. The enable password on this switch is "cisco."What can be determined from the output shown?The enable password is encrypted by default.An MD5 hashing algorithm was used on all encrypted passwords.Any configured line mode passwords will be encrypted in this configuration.This line represents most secure privileged EXEC mode password possible.9. What are two ways to make a switch less vulnerable to attacks like MACaddress flooding, CDP attacks, and Telnet attacks? (Choose two.)Enable CDP on the switch.Change passwords regularly.Turn off unnecessary services.Enable the HTTP server on the switch.Use the enable password rather than the enable secret password.10.
Refer to the exhibit. The switch and workstation are administrativelyconfigured for full-duplex operation. Which statement accurately reflectsthe operation of this link?No collisions will occur on this link.Only one of the devices can transmit at a time.The switch will have priority for transmitting data.The devices will default back to half duplex if excessive collisions occur.11. Where is the startup configuration stored?DRAMNVRAMROMstartup-config.text12. Refer to the exhibit.
What happens when Host 1 attempts to send data?Frames from Host 1 cause the interface to shut down.Frames from Host 1 are dropped and no log message is sent.Frames from Host 1 create a MAC address entry in the running-config.Frames from Host 1 will remove all MAC address entries in the address table.13. Which statement is true about the command banner login "Authorizedpersonnel Only" issued on a switch?The command is entered in privileged EXEC mode.The command will cause the message Authorized personnel Only to display before auser logs in.The command will generate the error message % Ambiguous command: "bannermotd" ” to be displayed.The command will cause the message End with the character “%” to be displayedafter the command is entered into the switch.14. Refer to the exhibit.
The network administrator’s attempts to connect toSwitch1 via Secure Shell are failing. What is most likely the problem?incorrect vty lines configuredincompatible Secure Shell versionincorrect default gateway addressvty lines that are configured to allow only Telnet15. What happens when the transport input ssh command is entered on theswitch vty lines?The SSH client on the switch is enabled.Communication between the switch and remote users is encrypted.A username/password combination is no longer needed to establish a secure remoteconnection to the switch.Стр. 13 из 1701.04.2009 0:46CISCO CCNA Certifications: CCNA 3 UPDATEDfile:///D:/botalka/%D1%81%D0%B8%D1%81%D1%8C%D0%BA...The switch requires remote connections via proprietary client software.16. Which two statements about Layer 2 Ethernet switches are true?(Choose two.)Layer 2 switches prevent broadcasts.Layer 2 switches have multiple collision domains.Layer 2 switches route traffic between different networks.Layer 2 switches decrease the number of broadcast domains.Layer 2 switches can send traffic based on the destination MAC address.17.
