I'm assuming that the Task 1.1 "solution" is either partially wrong or there is a typo. Maybe I'm wrong?
On the two trunk ports connecting the switches (fa0/20 & fa0/21) shouldn't both VLAN 9 and 10 be allowed to trunk between the switches? The solution only shows 9 on one switch and 10 on the other..
Shouldn't the allowed vlans be 9-10,59,1910 ? On both ports on both switches?
