Refer to the exhibit.
A technician has configured the FastEthernet 0/1 interface on Sw11 as an access link in VLAN 1.
Based on the output from the show vlan brief command issued on Sw12, what will be the result of
making this change on Sw11?
A.
Only the hosts in VLAN 1 on the two switches will be able to communicate with each other.
B.
The hosts in all VLANs on the two switches will be able to communicate with each other.
C.
Only the hosts in VLAN 10 and VLAN 15 on the two switches will be able to communicate with
each other.
D.
Hosts will not be able to communicate between the two switches.
Explanation:
VLANs are local to each switch’s database, and VLAN information is not passed between switches
without implementing VLAN Trunk Protocol (VTP). Trunks carry traffic from all VLANs to and from
the switch by default but, can be configured to carry only specified VLAN traffic. Trunk links are
required to pass VLAN information between switches. So Sw11 port should be trunk not access port.
Additionally, there are no ports assigned to VLAN 1.
OOh, trick question.
Had there been hosts configured into the native VLAN of VLAN 1, A. would’ve been the correct answer.
Since there are no hosts that are configured into VLAN 1 and the diagram shows that none of the access users are on VLAN 1, then no hosts which are currently a part of the network will be able to communicate with each other.

A could be correct. We do not know what hosts are connected, or what VLANs they are on. It is possible that one or more of the ports on SW12 are trunking, and the hosts are configured manually for VLAN1 on those trunks.
Which is awkward when you look at option D. Only one of the two can be correct. I don’t like this question.

Correct answer is A.
Vlan 1 (native) can communicate across switches without trunk ports.

o my god guys, from the output of switch 12 you can see vlan 1 has no ports in it. so answer is D
