Ok,

I have been doing some tests on a CD-ROM I have and here was one question

Which cisco layer is responsible for breaking up collision domains?


options....
physical access core network distribution datalink



Now the answer says this:

Answer "The access layer is where users gain access to the network and where cisco recommends uses plug into switches which break up collision domains


May I take this moment to say WTF??

Err.. Sorry, I was reading that thinking OSI model...

Access Layer:

Controls local end user access to internetwork resources.
Also called desktop layer.
The resources most users need will be available locally.
Distribution layer handles traffic for remote services.
Continued use of access lists and filters.
Creation of separate collision domains (segmentation).
Workgroup connectivity at Distribution layer.
Technologies such as DDR and Ethernet switching are seen in the Access layer.
Static routing is here.

Prohacker, I was thinking the same!!

I think it was poor wording in the test anyhow. I hope it doesn't come up in my final which is a couple of weeks away.

Cheers for the reply :)
