What are the common Ethernet specs needed to know for Net+?

Ive been looking for a simple chart to study (including the one on this site) but some of them have a lot more information then others. My idea was to memorize it, then start removing some of the fields and try to recreate the chart from memory.
Does anyone know which ones I NEED to know for the exam?
Thanks

Here is an example of a chart found on the web that seems like it has a little too much for the exam.

This is all good information for the exam but it looks like it was created for an older exam. If you look at the types listed in table 3.7 of the objectives, there are Designations (Types) that are missing such as 10GBaseSW, 10GBaseLW, and 10GBaseEW.

I realize it is a lot of trivia but you can indeed be asked questions on just about any of the data points. You certainly won't be asked questions on all of them on any single test, but it is all valid.

You could simplify it by creating multiple tables. For example, one table could be just for standards using twisted pair (10BaseT, 100BaseT, 1000 BaseT, and 10GBaseT), a second for standards using fiber, and a third for copper. A secondary benefit of recreating the table for yourself is that it helps solidify the knowledge for you.

By the way, your idea of recreating the chart from memory is a great study strategy. Also, even though you can't take notes into the exam room you can take notes on a paper they give you once you start the exam. You can recreate some tables as soon as you start and if you get any questions related to the topics, you can simply look at your notes to answer them.

Hope this helps.

Sound advice.
Thank you sir.

What did you end up going with? I need to memorize this material as well.
