This task requires you to use the CLI of Sw-AC3 to answer the multiple-choice question below.
This does not require any configuration.
Refer to the exhibit. SwX was taken out of the production network for maintenance.
It will be reconnected to the Fa0/16 port of Sw-AC3. What happens to the network when it is
reconnected and a trunk exists between the two switches?
SwX#show vlan | SwX#show vtp stat
Sw-AC3#show vtp stat
Sw-AC3#show vlan
A.
All VLANs except the default VLAN will be removed from all switches.
B.
All existing switches will have the students, admin, faculty, Servers, Management, Production,
and no-where VLANs.
C.
The VLANs Servers, Management, Production, and no-where will replace the VLANs on SwX.
D.
The VLANs Servers, Managements, Production, and no-where will be removed from existing
switches.
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). Also, some recent comments have said that the new switch’s VTP
Operating Mode is Server but the answer is still the same.
