Hi guys,

I am going to take the A+ 901 exam probably in the next week, but I would like to know if I need to know the OSI model. I know this was asked on the sub before, but not in a while.

    CompTIA's exam objectives state 16% of the exam covers "Industry Standards, Practices and Network Theory". It then later says it expects you to analyze a scenario and determine the corresponding layer in the OSI model.

    It looks like you may have one or two questions but not much. I've been studying for about a month now for it and all training materials I've been using covers it. I'd reccomend checking out the exam objectives at:

    Most certification companies publish the topics of each exam. You can find the ones for CompTIA at

    If it is listed on the objectives, then you should understand the item. More likely geared toward NET+ candidates, but why not learn the OSI model as it is something a professional needs to know. And yes, it has been asked before and the answer is likely the same ;)

    'i' before 'e' except after 'c'.... weird?
