Test Your Knowledge
Emmett Dulaney
Think you're ready to whip out the company credit card and register for that
certification exam that has caught your eye? Before you do, test your knowledge
with this sample exam of questions covering basic to intermediate-level Linux/Unix
topics.
One caveat: over time, I've learned that there are risks involved in writing
practice tests. The risks fall into two categories: first, there is almost always
more than one way to do the same task in Linux or Unix, and second, *nix users
love to point out that none of the possible answers are the way they would do
it; they have a script they wrote, an application they purchased, or a friend
who knows a guy who has a tool, etc.
When you take an exam, however, whether it's Linux+ from CompTIA, an exam
from the Linux Professional Institute, or any other non-lab-based test, you
have to pick the best answer from those choices presented to you. Don't over-think
the question and talk yourself out of the correct answer.
With that said, let's see how well you do! (The answers can be found at the
end of this article.)
