Refer to the topology and router output shown in the exhibit. A technician is troubleshooting host connectivity issues on the switches. The hosts in VLANs 10 and 15 on Sw11 are unable to communicate with hosts in the same VLANs on Sw12. Hosts in the Admin VLAN are able to communicate. The port-to-VLAN assignments are identical on the two switches.
What could be the problem?
A.
The Fa0/1 port is not operational on one of the switches.
B.
The Link connecting the switches has not been configured as a trunk.
C.
At lease one port needs to be configured in VLAN 1 for VLANs 10 and 15 to be able to communicate.
D.
Port FastEthernet 0/1 needs to be configured as an access link on both switches.
E.
A router is required for hosts on Sw11 in VLANs 10 and 15 to communicate with hosts in the same VLAN on Sw12.
1-There is no Router connected
2- Its a switch output.
3- Although answer is right, but this is one of the problems…. Other problem is absence of router to run vlans in the network.
This is not intervlan communication. No Router is required. Communication from vlan 10 to valn 10 members on other switch and from vlan 15 to vlan 15 on other switch is in question
If the link between the switches is not configured as Trunk, it can cause the described problem.
Suggested answer is B.
F0/1 must be added in vlan 1 and it must allow every VLAN like ” Switchport mode trunk ; switchport trunk allowed vlan 10,20,30 ” ??
