Refer to the topology in question 6; if you replace the hub with a six ports switch; how many collision domain(s) and broadcast domain(s) do we have 6 broadcast domain, 1 collision domain 1 broadcast domain, 6 collision domain 2 broadcast domain, 1 collision domain 1 broadcast domain, 1 collision domain Refer to the topology above; how many broadcast domain(s) do you see 1 4 or more
