Home > CCNA VTP SIM Question


February 21st, 2014 Go to comments


Refer to the topology below, you are only allowed to access the CLI of Sw-AC3 to answer some questions. This does not require any configuration.


You can download this sim to practice here (but notice that this sim is not perfect, only for practicing purpose): http://www.9tut.com/download/9tut.com_CCNA_vtp_sim.pka

If you are not sure about VTP, please read my VTP Tutorial

Question 1


To find out which interface associated with a given MAC address, use the show mac address-table command. It shows the learned MAC addresses and their associated interfaces. After entering this command, you will see a MAC address table like this:


From this table we can figure out that the MAC address 0010.5a0c.ffba is associated with interface Fa0/8.

Note: There are some reports that the “show mac-address-table” command does not exist. So if you cannot use the “show mac-address-table” command then try using the “show mac address-table” (without “-“) instead.

Question 2


Use the show interface trunk command to determine the trunking status of a link and VLAN status. This command lists port, its mode, encapsulation and whether it is trunking. The image below shows how it works:


(This image is used for demonstration only)

Question 3


VLAN-R1 is the router directly connected to Sw-Ac3 switch, so we can use the show cdp neighbors command to see:

1. Neighbor Device ID : The name of the neighbor device;

2. Local Interface : The interface to which this neighbor is heard

3. Capability: Capability of this neighboring device – R for router, S for switch, H for Host etc.

4. Platform: Which type of device the neighbor is

5. Port ID: The interface of the remote neighbor you receive CDP information

6. Holdtime: Decremental hold time in seconds

Sample output of show cdp neighbors command:


One thing I want to notice you is “Local Intrfce” in the image above refers to the local interface on the device you are running the “show cdp neighbors” command

Question 4


First we use the show spanning-tree vlan 1 to view the spanning-tree information of VLAN 1


From the “Cost 19”, we learn that the root switch is directly connected to the Sw-Ac3 switch over a 100Mbps Ethernet link

Notice that if you see all of the interface roles are Desg (designated) then you can confirm Sw-Ac3 switch is the root bridge for this VLAN (VLAN 1).

If you see there is at least one Root port in the interface roles then you can confirm Sw-Ac3 is not the root bridge because root bridge does not have root port. In this case, we notice that the root port on Sw-Ac3 switch is FastEthernet0/12, so we have to figure out which switch is associated with this port -> it is the root bridge. You can verify it with the show cdp neighbors command:


The “Local Intrfce” column refers to the interface on the switch running “show cdp neighbors” command. In this case, Sw-DS1 is associated with interface FastEthernet0/12 -> Sw-DS1 is the root bridge

Question 5


First we have to identify which VLAN interface Fa0/4 belongs to by the show vlan command


From the exhibit we know that VLAN 44 is configured on router using sub-interface Fa0/0.44 with IP address


Therefore the default gateway of the host should be

Question 6


To view the VTP configuration information, use the show vtp status command


So we knew Sw-Ac3 received VLAN information from (notice:the IP address may be different). Finally we use the show cdp neighbors detail to find out who is:


Note: If in the exam you find that “Configuration last modified by” then “” here indicates it does not receive VLAN information from anyone -> Sw-Ac3 is also the local updater. Therefore the answer in this case is Sw-Ac3.

Question 7

Answer and Explanation

First we should view the VTP configuration of switch Sw-Ac3 by using the show vtp status command on Sw-Ac3


Notice that its configuration revision number is 5 and VTP Domain Name is home-office

Next, from the exhibit we know that SwX has a revision number of 6, which is greater than that of Sw-Ac3 switch, and both of them have same VTP Domain Name called “home-office”.


Therefore SwX will replace vlan information on other switches with its own information. We should check vlan information of Sw-Ac3 switch with show vlan command


So the correct answer is D – The VLANs Servers, Management, Production and no-where will be removed from existing switches

Please notice that in the real CCNA exam you may see a different configuration revision of Sw-Ac3 or of SwX. In general, which switch has a higher revision number it will become the updater and other switches will overwrite their current databases with the new information received from the updater (provided that they are on the same domain and that switch is not in transparent mode). In particular, if the revision number of SwX is lower than that of Sw-Ac3, the answer should be “C – The VLANs Servers, Management, Production and no-where will replace the VLANs on SwX”.

Also, some recent comments have said that the new switch’s VTP Operating Mode is Server but the answer is still the same.

Note: If a switch is in client mode and has a higher Revision number, it can still update other Server switches (with lower Revision numbers).

Question 8


First we check to see which ports the source mac-address and the destination mac-address belong to by using show mac address-table command


We notice that the source mac-address 0010.5a0c.fd86 is listed in the table and it belongs to Vlan 33 but we can’t find the destination mac-address 000a.8a47.e612 in this table. In this case, the switch will flood to all ports of Vlan 33 and flood to all the trunk links, except the port it received this frame (port Fa0/6). Therefore from the output above, we can figure out it will flood this frame to Fa0/1, Fa0/3 and Fa0/12.

Please notice that the “show mac-address-table” command just lists information that was learned by the switch, it means that there can be other ports besides Fa0/1, Fa0/3 and Fa0/12 belong to Vlan 33. You can use the show vlan command to see which ports belong to vlan 33


And we found other ports which belong to vlan 33, they are Fa0/2, Fa0/5 and Fa0/7. Our switch will flood the frame to these ports, too.

And we can check which trunk ports will receive this frame by the show interface trunk command


-> Port Fa0/9 will also receive this frame!

Note: Some reports said there is another version of this question. A reader on 9tut commented:

Another question on the VTP SIM was” What will be the destination MAC address of a packet with Source IP address and destination IP address 192.0.2.X (doesn’t really matter what will be the Dest. IP address, since it will be sent to the router).
The answer is simple:
Since the source IP address belongs to VLAN 44, the default gw of the sender is the Router’s Subinterface, and this is where the packet will be sent. Thus, you need to perform a ‘show cdp nei’ on the Sw-AC3 in order to find the local FastEthernet port where the router is connected. Then execute a “show mac address-table” (this command was functioning) and find the mac address associated with the previous port. This is the answer.

Question 9

Answer and Explanation:

Because the destination address is not on the same subnet with the switch, it will forward the packet to its default gateway. So we have to find out who is the default gateway of this switch by using the show running-config command


From the output, we notice that its default-gateway is In fact, we can easily guess that its default gateway should be a layer 3 device like a router; and in this case, the VLAN-R1 router. To verify our theory, use the show cdp neighbor detail command and focus on the description of VLAN-R1 router


From this output, we can confirm the switch’s default gateway is VLAN-R1 router (with the IP address of And “the interface: FastEthernet0/3” tells us that the switch is connected to VLAN-R1 router through Fa0/3 port (Fa0/3 is the port on the switch).

Finally we just need to use the show mac-address-table command to find out which MAC address is associated with this interface


And we find out the corresponding MAC address is 000a.b7e9.8360. Although there are some entries of port Fa0/3 with different Vlans but they have the same MAC address

    On this VTP question I notice here in your answer you do a sh run command and it shows you a default gateway, but in the actual packet tracer you have made here it doesn’t have a default gateway set. My only other comment is on question 5, everything is good but the packet tracer (at least to my knowledge) does not have that list of ip’s you reference in your answer. Otherwise all else looks great, thank you for your great simulations, I am taking test Thurs. if I pass it’ll be because of your material.

    On the question #9

    I think the default gateway of the switch has nothing to do with the direction of the packet/frame, the packet will just go the the default gateway of the host which is connected to the fa0/3.

    it doesn’t show the default gateway
    and m getting different mac addr on sw-ac3

    If the “last modified by” value is in the actual switch, it is not necessary the “local updater”. If the vtp server does not have a management IP defined, the value will not be propagated and there is no way to assume a local update.

    salam to all
    I Passed 11 July , 2016 at 18:15 33 score: 941/1000
    i just got lucky 40 questions on my exam
    All question from watson 314Q is still valid
    here’s my lab that i encountered…
    OSFP Tshot – Same
    ACL1 – Same
    ACL2 – Same (mod 4)
    (please be mindful for the IP address that will be given,
    & test the host C if you able to access finance server thur WEB)
    EIGRP troubleshooting answer:
    Q1: The loopback addresses haven’t been advertised, and the network command is missing on R4.
    Q2: The traffic is equally load-balanced over R2 and R3.
    Q3: The K values mismatch.
    Q4: The network statement is missing on R5
    Tips: before to take the exam pray, relax don’t pressure yourself to all LABS
    the secret for real pass4sure is study, all the CCNA topics, watson is one big help
    & GOD BLESS…
    special thanks to my bro Jamiullah Marwat who gives courage for CCNA

    Question 9 – Can you plz correct my thoughts
    When one host will send packet outside subnet, we need to use that Subnet Router
    Hosts are connect on ports 4, 6, 8, 10 which belongs to either VLAN 33, 44

    Furthermore, IP default-gateway in switch is used for management of switch itself

    Thnx in advanced

    i got two labs..1 ACL and another OSPF
    rest 62 questions were very difficult.
