Help with a Transcender question...

This Transender question has me confused:

What are the two characteristics of segmenting a LAN using switches? (choose two)

1. Each segment has its own broadcasting domain

2. Each segment has its own collision domain

3. The entire network has a single collision domain

4. The entire network has a single broadcast domain

I answered 1 and 4, 1 is wrong and 4 is right. 2 and 4 are the right answers.

I thought the effect of switches is to create collision domains for each port as frames are only destined for the appropriate port per MAC table?

How does each segment have its own collision domain?

swithces separate collision domains, therefore each port or segment on a swith has its own collision domain but there are still part of the same broadcast domain.

Just about every single practice test out there will have a question like this one. I guess that means that everyone taking the CCNA should pay close attention to this type of question.

Your router seperates the broadcast domains.

dont routers separte broadcast, and collision domains

Yes they do..But if you had a switch connected to a router, the link between the swtch and the router would only be 1 collision domain. There could be more, depending on if anything else is conected to the switch.

So each port = 1 segment, so if you had a 24 port switch and 24 pc's plugged in this is seen as 24 collision domains and 1 broadcast domain.

I think whats confusing me is the clasification of a segment! I was thinking it was the pc's and switch were a segment.

That is correct.
