CCNA – Switch Questions 2
Only router can break up broadcast domains but in this exhibit no router is used so there is only 1 broadcast domain.
For your information, there are 7 collision domains in this exhibit (6 collision domains between hubs & switches + 1 collision between the two switches).
From the output we notice that the administrator has just shut down Interface Vlan1, which is the default VLAN so no one can access it remotely (like telnet) -> B is correct.
Answer A is not correct as STP calculation does not depend on which port comes up first or last. STP recalculates when there is a change in the network.
A normal switch can operate without VLAN -> C is not correct.
This IOS does support VLAN because it has VLAN 1 on it -> D is not correct.
