    Ok, so i've been studying hard for Net+ lately, and I felt it was time to do a practice test to see how I got on. On reviewing the incorrect answers, im lost.

    If I wanted to upgrade my Ethernet network from 10Mbps to 100Mbps, what CAT cable would I need to install?

    I answered CAT 3, due to 100BaseT4. The correct answer is showing as CAT 5.


    Im unaware if im breaking any agreements by posting the "rough" question on here, but its really confused me. Even in the explaination of the answer, it clearly says 100BaseT4 is 100Mbps with four pairs in CAT 3 cabling. :blink

    Any care to explain/help?

    Thanks :twisted:

    CAT3 is 10Mbits/s as *standard* however CAT5 is 100Mbits/s.

    The 100baseT4 standard was used with older CAT3 installs to get them up to fast Ethernet speed (100Mbits/s).

    If there is no mention of the newer standard then CAT3 is running at 10Mbits/s. 8)

    Almost nobody uses 4pair 100Mbit these days. The norm is 2 pair, as with 10Mbit. Hence needing the better cable.
