I'm studying on the 642-813 exam and i can't get a clear anwser on the floowing question about VTP pruning
(see picture attached)
The certification guide states that broadcasts and unicast floodings on a vlan are blocked on trunks to switches which doesn't have interfaces in that vlan.
The picture shows broadcast traffic send from host A to host B. Why is this broadcast traffic passed along switch 2 which doesn't have interfaces in the Red vlan?
thanx in advance
