CCNA Tcsa 14 - Switching Exam

Let’s switch things up, shall we? Today we’ll be looking at the topic of packet switching with regards to your progress in the Cisco Certified Network Associate. Switching is a method of grouping data which is transmitted over a digital network into packets. What do you know about it?


Questions and Answers
  • 1. 
    What VLANs are allowed across a trunk when the range of allowed VLANs is set to the default value?
    • A. 

      Only the management VLAN

    • B. 

      All VLANs except the extended range VLANs

    • C. 

      All VLANs except 1 and 1002-1005

    • D. 

      All VLANs

  • 2. 
    Which value determines if a switch becomes the central point of reference in the spanning tree topology?
    • A. 

      Lowest bridge ID

    • B. 

      Highest revision number

    • C. 

      Lowest numeric IP address

    • D. 

      Highest numeric MAC address

  • 3. 
    An administrator is troubleshooting a PC on the network which is suffering from slow and intermittent connectivity. The PC has a ping success rate to the default gateway of less than half the ping attempts. Other PCs on the switch can consistently ping the default gateway. The switch port is configured for auto duplex and the PC is configured for full duplex. What will commonly cause this problem?
    • A. 

      The PC is set to full duplex. The switch port fails to autonegotiate the duplex setting and defaults to half duplex, which causes a duplex mismatch.

    • B. 

      The switch traffic is exceeding available frame buffers. The result is that frames are being dropped.

    • C. 

      The PC and the default gateway have different bandwidth Ethernet ports.

    • D. 

      The default gateway is not on the same switch that the PC is.

  • 4. 
    What is the purpose of the Spanning Tree algorithm?
    • A. 

      It propagates VLAN configurations to other switches.

    • B. 

      It restricts broadcast packets to a single VLAN.

    • C. 

      It segments a network into multiple broadcast domains.

    • D. 

      It prevents loops in a switched network with redundant paths.

  • 5. 
    Refer to the exhibit. An administrator documented the output of a CAM table from an Ethernet switch as shown. What action will the switch take when it receives the frame shown at the bottom of the exhibit?
    • A. 

      Discard the frame

    • B. 

      Forward the frame out port 2

    • C. 

      Forward the frame out port 3

    • D. 

      Forward the frame out all ports

    • E. 

      Forward the frame out all ports except port 3

    • F. 

      Add station 00-00-3D-1F-11-05 to port 2 in the forwarding table

  • 6. 
    Refer to the exhibit. What is the maximum number of VLANs that can be deleted from the Switch as it is configured?
    • A. 

      Zero

    • B. 

      Four

    • C. 

      Five

    • D. 

      Eight

  • 7. 
    Refer to the exhibit. Each switch is configured to participate in STP for VLANs 1, 10, 20, and 30. Which switch will become the root for VLAN 20?
    • A. 

      A

    • B. 

      B

    • C. 

      C

    • D. 

      D

  • 8. 
    Which type of VLAN would accommodate untagged traffic on a 802.1q trunk port?
    • A. 

      Data VLAN

    • B. 

      Native VLAN

    • C. 

      Untagged VLAN

    • D. 

      Management VLAN

  • 9. 
    Refer to the exhibit. All trunk links are operational and all VLANs are allowed on all trunk links. An ARP request is sent by computer 5. Which device or devices will receive this message?
    • A. 

      Only computer 4

    • B. 

      Computer 3 and RTR-A

    • C. 

      Computer 4 and RTR-A

    • D. 

      Computer 1, computer 2, computer 4, and RTR-A

    • E. 

      Computer 1, computer 2, computer 3, computer 4, and RTR-A

    • F. 

      All of the computers and the router

  • 10. 
    Refer to the exhibit. VLAN 20 was recently added on the network. Users on VLAN 20 on SW1 start complaining that they do not have connectivity to the users on the same VLAN on switch SW2. What should be done to remedy the problem?
    • A. 

      Configure the trunk port in a desirable mode on SW2.

    • B. 

      Include VLAN 20 in the list of allowed VLANs on the trunk link on SW2.

    • C. 

      Configure VLAN 1 to be the native VLAN for both networks on SW1 and SW2.

    • D. 

      Remove VLAN 20 from the allowed VLANs on the trunk link on SW2, an action that will enable all VLANs on the trunk link.

  • 11. 
    Refer to the exhibit. A network administrator enters the displayed commands to configure VLAN 30. What is the result of running these commands?
    • A. 

      VLAN 30 will be added to S1, S2, and S3, but not to S4.

    • B. 

      VLAN 30 will be pruned from the VLAN database of S3.

    • C. 

      VLAN 30 will be added to the VLAN database of S3 but will not be propagated to S4, S2 or S1.

    • D. 

      VLAN 30 will not be added to the VLAN database of S3 and an error message will be displayed.

  • 12. 
    Refer to the exhibit. What would happen if the network administrator moved the network cable of Host A from interface Fa0/1 to Fa0/3 on switch SW1?
    • A. 

      Host A remains a member of VLAN 10, because the router is routing traffic between VLANs.

    • B. 

      Host A is no longer a member of VLAN 10, because port Fa0/3 has been manually assigned to VLAN 30.

    • C. 

      Host A remains a member of VLAN 10, because the switch provides dynamic VLAN assignment for the port.

    • D. 

      Host A maintains connectivity to all members of VLAN 10, because it is connected to the same physical network.

    • E. 

      Host A is no longer a member of VLAN 10, but because port Fa0/3 was unused, it is now a member of VLAN 1.

  • 13.

      STP

    • B.
