CCNA 3 Scaling Networks Ver 6.0 – ITN Chapter 2 Exam Answers

CCNA 3 Chapter 2 Exam Answers

  1. Where is the vlan.dat file stored on a switch?

    on the externally attached storage media or internal hard drive

    in RAM

    in NVRAM

    in flash memory*

  2. How are IP addressing designs affected by VLAN implementations?

    Each VLAN must have a different network number.*

    VLANs do not use a broadcast address.

    VLANs do not support VLSM.

    Each VLAN must have a different subnet mask.

  3. What is a disadvantage of using multilayer switches for inter-VLAN routing?

    Multilayer switches have higher latency for Layer 3 routing.

    Spanning tree must be disabled in order to implement routing on a multilayer switch.

    Multilayer switches are more expensive than router-on-a-stick implementations.*

    Multilayer switches are limited to using trunk links for Layer 3 routing.

  4. While configuring inter-VLAN routing on a multilayer switch, a network administrator issues the no switchport command on an interface that is connected to another switch. What is the purpose of this command?

    to create a switched virtual interface

    to create a routed port for a single network*

    to provide a static trunk link

    to provide an access link that tags VLAN traffic

  5. What happens to switch ports after the VLAN to which they are assigned is deleted?

    The ports are placed in trunk mode.

    The ports are assigned to VLAN1, the default VLAN.

    The ports stop communicating with the attached devices.*

    The ports are disabled.

  6. Given the following configuration, which two statements are true? (Choose two.)

    switch(vlan)# vtp version 2
    switch(vlan)# vtp mode server
    switch(vlan)# vtp domain Cisco
    switch(vlan)# vtp password mypassword

    This switch can advertise its VLAN configuration to other switches in the Cisco domain only, but can receive advertisements from other domains.

    This switch maintains a full list of all VLANs and can create VLANs, but cannot delete or modify existing VLANs.

    This switch can send and receive advertisements from only the Cisco domain.*

    This switch can create, modify, and delete all VLANs within the Cisco domain.*

    The password will prevent unauthorized routers from participating in the Cisco domain.

  7. A switch is participating in a VTP domain and configured as a VTP server. The switch needs to propagate VLAN 10 (used by the Manufacturing department) throughout the VTP domain, but does not have any directly connected hosts using that particular VLAN. Which configuration would satisfy this requirement?

    interface fa0/24
    switchport mode access
    switchport access vlan 10

    vlan 10
    name Manufacturing

    vtp mode server
    vtp password Manufacturing

    interface g0/1
    switchport mode trunk
    switchport trunk native vlan 10

  8. Which command should the network administrator implement to prevent the transfer of DTP frames between a Cisco switch and a non-Cisco switch?

    S1(config-if)# switchport mode trunk

    S1(config-if)# switchport trunk allowed vlan none

    S1(config-if)# switchport mode dynamic desirable

    S1(config-if)# switchport mode access

    S1(config-if)# switchport nonegotiate*

  9. What is a characteristic of a routed port on a Layer 3 switch?

    It is not assigned to a VLAN.

    It is commonly used as a WAN link.

    It supports trunking.

    It cannot have an IP address assigned to it.

  10. Refer to the exhibit. The switch does the routing for the hosts that connect to VLAN 5. If the PC accesses a web server from the Internet, at what point will a VLAN number be added to the frame?

    point E

    point B

    point D

    point A

    point C

    No VLAN number is added to the frame in this design.*

  11. Fill in the blank.

    In a Cisco switch, the extended range VLAN information is stored in the_____________file.

    Correct Answer: running configuration

  12. Which three actions can cause problems with a VTP implementation? (Choose three.)

    using a non-trunk link to connect switches*

    using lowercase on one switch and uppercase on another switch for domain names*

    not using any VTP passwords on any switches

    configuring all switches to be in VTP server mode

    using non-Cisco switches*

    having a VTP transparent switch in between a VTP server switch and a VTP client switch (all switches in the same VTP domain)

  13. Which two events will cause the VTP revision number on a VTP server to change? (Choose two.)

    changing the switch to a VTP client

    rebooting the switch

    changing interface VLAN designations

    adding VLANs*

    changing the VTP domain name*

  14. Refer to the exhibit. Communication between the VLANs is not occurring. What could be the issue?

    A duplex issue exists between the switch and the router.

    Default gateways have not been configured for each VLAN.

    The wrong port on the router has been used.

    The Gi1/1 switch port is not in trunking mode.*

  15. Which two VTP parameters must be identical on all switches in the network in order to participate in the same VTP domain? (Choose two.)

    VTP transparent mode

    VTP server mode

    VTP domain password*

    VTP client mode

    VTP domain name*

    VTP revision number

  16. What is a characteristic of VTP?

    Switches in VTP transparent mode revert back to VTP server mode after a reboot.

    Switches in VTP server mode cannot be updated by switches in VTP client mode.

    Switches in VTP transparent mode forward VTP advertisements.*

    Switches in VTP client mode store VLAN information in NVRAM.

  17. Under which two occasions should an administrator disable DTP while managing a local area network? (Choose two.)

    on links that should dynamically attempt trunking

    when connecting a Cisco switch to a non-Cisco switch*

    when a neighbor switch uses a DTP mode of dynamic auto

    when a neighbor switch uses a DTP mode of dynamic desirable

    on links that should not be trunking*

  18. Refer to the exhibit. A network administrator is configuring inter-VLAN routing. However, the communication between VLAN 10 and VLAN 20 fails. Based on the output of the show vlancommand, what is the cause of the problem?

    Gi1/1 and Gi1/2 are not configured as trunk mode.

    The IP addresses on Gi0/0 and Gi0/1 are switched by mistake.

    The IP addresses on Gi0/0 and Gi0/1 are not on the same network.

    Gi1/1 and Gi1/2 are not assigned to their respective VLANs.*

  19. Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Fill in the blank. Do not use abbreviations.

    Which command is missing on the Layer 3 switch to restore the full connectivity between PC1 and the web server? (Note that typing no shutdown will not fix this problem.) ____________

    Correct Answer: ip address

  20. How is traffic routed between multiple VLANs on a multilayer switch?

    Traffic is broadcast out all physical interfaces.

    Traffic is routed via internal VLAN interfaces.*

    Traffic is routed via subinterfaces.

    Traffic is routed via physical interfaces.

  21. Refer to the exhibit. A network administrator is verifying the configuration of inter-VLAN routing. Users complain that PC2 cannot communicate with PC1. Based on the output, what is the possible cause of the problem?

    The command interface GigabitEthernet0/0.5 was entered incorrectly.

    The no shutdown command is not entered on subinterfaces.

    There is no IP address configured on the interface Gi0/0.

    The encapsulation dot1Q 5 command contains the wrong VLAN.*

    Gi0/0 is not configured as a trunk port.

  22. Refer to the exhibit. A router-on-a-stick configuration was implemented for VLANs 15, 30, and 45, according to the show running-config command output. PCs on VLAN 45 that are using the /24 network are having trouble connecting to PCs on VLAN 30 in the /24 network. Which error is most likely causing this problem?

    There is an incorrect IP address configured on GigabitEthernet 0/0.30.*

    The GigabitEthernet 0/0 interface is missing an IP address.

    The wrong VLAN has been configured on GigabitEthernet 0/0.45.

    The command no shutdown is missing on GigabitEthernet 0/0.30.

  23. Refer to the exhibit. After attempting to enter the configuration that is shown in router RTA, an administrator receives an error and users on VLAN 20 report that they are unable to reach users on VLAN 30. What is causing the problem?

    RTA is using the same subnet for VLAN 20 and VLAN 30.*

    There is no address on Fa0/0 to use as a default gateway.

    The no shutdown command should have been issued on Fa0/0.20 and Fa0/0.30.

    Dot1q does not support subinterfaces.

  24. Which command displays the encapsulation type, the voice VLAN ID, and the access mode VLAN for the Fa0/1 interface?
