802.3.............

Just wondering how often questions pop up asking you to name an IEEE standard.

For example, I am answering a question now from a test site asking: "You want to implement 1000Mbps Ethernet. Which IEEE standards apply in this scenario?" It then goes on to list:
802.3u, 802.3ab, 802.3i, 802.3z, 802.ae, 802.e. The correct answer being 802.3ab and 802.3u.

Should I have all these memorized? I know what some of the obvious ones are, such as 802.1q.

Thanks

    The correct answer being 802.3ab and 802.3u.

    Yes, it's but better to understand the diff. of all IEEE
    Gigabit Ethernet still use the old ways of IEEE 802.3 MAC and IEEE 802.2
    LLC.

    1000 MBPS to 1gbps requires

    802.ab - for electrical cabling
    802.3 u is for optical cabling

    yes, I agree with chinaman. You will face these in just about every networking test from now on. You need to go ahead and learn them now.

    Thanks for the feedback. Anyone know the best way to tackle that? Should I just start skimming through the books, and anywhere I see a 802.x, write it down and memorize what it relates too? For example, after all my studying, I feel pretty confident with my STP knowledge. But did I ever take note that it was 802.1d? Nope. Time to start memorizing.
