    2
    A network administrator has just finished configuring a switch with multiple VLANs. A workstation on VLAN2 cannot communicate with a workstation on VLAN3. What needs to be done to correct this problem?

    The traffic needs to be routed between the two VLANs.

    The hosts must be reconfigured to be on the same logical network.

    The VLANs need to be configured to be on the same broadcast domain.

    The switch must be configured to share VLAN traffic.



    3

    membership by MAC address

    membership by logical address

    membership by protocol

    membership by port

    membership by operating system



    4
    What needs to be done when deleting an entire VLAN? (Choose three.)

    Enter database configuration mode.

    Reboot the switch in order for the changes to take effect.

    Use the negative form of the command that was used to create the VLAN.

    Reassign the switch ports from the deleted VLAN to other VLANs if they are to be used.

    Use the erase vlan command in global configuration mode.

    Delete the vlan.dat file from flash.



    5
    Which of the following statements are true regarding a root bridge in a spanning tree topology? (Choose two.)

    The root bridge timers control BPDU traffic on the network.

    Only the show commands on the switch can display root bridge information.

    It is the central point of a spanning tree topology.

    Storm control is enabled by default.

    VLANs cannot be trunked between switches until the root bridge has been elected.



    6
    Which factors influence the number of VLANs that may be required on a switch? (Choose three.)

    the physical addressing scheme

    traffic patterns in the network

    types of applications in use

    the adaptability of the network

    workgroup functions and commonality

    the tagging option used for VLAN identification



    7
    How does the use of VLANs benefit an organization? (Choose two.)

    by centralizing departmental staff and network resources together in a single physical area

    by allowing organizational flexibility by grouping users together by function instead of physical location

    by simplifying the task of adding and moving network resources and users in a growing organization

    by reducing the number of broadcast domains in an enterprise network

    by eliminating the need for routing traffic in large networks

    by reducing network management costs by replacing many Layer 2 devices with a few Layer 3 devices



    8
    What does a switch do when it receives a frame and the source address is unknown?

    The switch will discard the frame.

    The switch will request the sender resend the frame.

    The switch will map the source address to the port on which it was received.

    The switch will flood the frame to all attached devices.

    The switch will issue an ARP request to confirm that the source exists.



    9
    If two 12-port hubs are connected to a switch that has three VLANs configured, how many bridging tables will the switch maintain?

    1

    2

    3

    12

    36



    10
    If a switch connects 12 collision domains and is configured with three VLANs, how many broadcast domains does it have?

    1

    3

    4

    12



    11



    Refer to the network shown in the graphic. Host A on VLAN1 has sent a message requesting the MAC address of its default gateway. Which of the following network hosts will process this message?

    The message will be seen by the hosts on VLAN1 and VLAN2.

    The message will be seen only by the hosts connected to Switch1.

    The message will be seen only by the hosts connected to VLAN1 on Switch1.

    The message will be seen by the hosts connected to VLAN1 on Switch1 and Switch2.

    The message will only be seen by router interface e0.



    12
    Switch-A and Switch-B are both configured with ports in the Marketing, Sales, Accounting, and Admin VLANs. Each VLAN contains 12 users. How many different subnetworks will be needed to enable routed connectivity between the VLANs?

    1

    4

    12

    48



    13
    What are the characteristics of VLAN1 in a default switch configuration? (Choose three.)

    CDP messages are only sent on VLAN1.

    VLAN1 is reserved for links between switches.

    All switch ports are members of VLAN1.

    VLAN1 must be created before ports can be assigned to it.

    Only switch port 0/1 is assigned to VLAN1.

    An IP address configured on the switch will only apply to ports on VLAN1.



    14
    What happens to the member ports of a VLAN when the VLAN is deleted?

    They become inactive.

    They default back to the management VLAN.

    They automatically become a part of VLAN1.

    They must be assigned to another VLAN before the original VLAN can be deleted.

    They remain a part of that VLAN until the switch is rebooted. They then become members of the management VLAN.



    15
    A network administrator has configured a switch with three VLANs: VLAN1, VLAN2, and VLAN3. Port 10 is to be assigned to VLAN3. Which of the following commands are needed to assign port 10 to VLAN3? (Choose three.)

    Switch_1(config)# switchport interface fastethernet 0/10

    Switch_1(config-if)# switchport mode access

    Switch_1(config-if)# switchport access

    Switch_1(config-if)# switchport access vlan 3

    Switch_1(config)# interface fastethernet 0/10

    Switch_1# vlan database


    16
    VLAN 10 needs to be removed from a switch. Which command must the administrator enter in order to accomplish this task?

    Switch(config-if)# no switchport access vlan 10

    Switch(config-if)# erase switchport access vlan 10

    Switch(vlan)# no vlan 10

    Switch(vlan)# no vlan database 10



    17
    A network administrator is attempting to configure routing between VLANs over a trunked link. A trunk link cannot be established between a switch and a router. Which of the following are possible sources of this problem? (Choose two.)

    The router IOS does not support trunking.

    The port is connected and is not receiving alignment and FCS errors.

    The switch duplex and speed are not set properly.

    The router and switch are running different versions of STP.

    The switch IP address is incorrectly configured.



    18
    Which of the following states the 80/20 rule of end-to-end VLANs?

    80% of network resources should be remote and 20% should be on the local VLAN.

    80% of VLANs should be static and the remaining 20% should be dynamic.

    80% of network traffic should be local and 20% remote.

    80% of the network sources should be centralized at the core layer and the remaining 20% at the distribution layer.

    80% of traffic should be routed and 20% should be switched.



    19
    Which of the following are methods of establishing VLAN membership? (Choose three.)

    logical addresses

    physical addresses

    ISL addresses

    switch port attachment

    hardware platform

    traffic pattern



    20
    What is true of the method by which VLAN membership is identified in Ethernet frames? (Choose two.)

    The frame header is in its original format when it reaches the endpoint device.

    The VLAN membership of frames does not need to be identified unless ISL is in use.

    The Ethernet frame is encapsulated or modified with the VLAN ID information.

    The VLAN ID is removed by the endpoint device upon delivery of the frame.



    21
    How does a bridge handle the frames that it receives? (Choose three.)

    If the source is unknown, the source port is shutdown.

    If the source port of a frame is unknown, a bridge will issue an ARP request.

    If the destination is on another segment, the bridge forwards the frame only to the correct interface.

    A bridge forwards frames for unknown destinations to the default gateway.

    If the destination port is unknown, a bridge will flood the frame to all ports in the broadcast domain, except for the source port.

    If the destination of the frame is on the same segment as the source, a bridge will not forward the frame.



    22
    Which of the following commands will assign switch port 0/9 to VLAN3?

    Switch(config-if)# switchport access vlan 3

    Switch(config-if)# switchport vlan 3

    Switch(config-if)# switchport access 3

    Switch(vlan)# switchport 0/9

    Switch(vlan)# access switchport 0/9



    23
    A network administrator has configured a switch with VLANs. Hosts will join the VLANs based on their MAC or IP address. What type of VLANs have been configured on the switch?

    dynamic

    database

    multiple

    port-based



    24
    Which of the following describe networks in which the use of static VLANs is appropriate? (Choose three.)

    Workstations, departments, and network resources are seldom moved.

    VLAN port membership frequently changes.

    Robust VLAN management software is available to the network administrator.

    The overhead required to manage VLAN MAC address and custom filtering tables is not desirable.

    VLANs are often added, deleted, and modified.
