Daniel Petri’s MCSE & System Administrator Interview Questions – Part 8 – Windows Server 2008/R2 Hyper-V and Virtualization

This is a part 8 of my MCSE and System Administrator job interview sample questions. See previous parts at:

Like previous parts, this article set is targeted at both the interviewer (who needs a pool of valid questions they can ask) and to the candidate (who wants a pool of sample questions they can prepare for). Needless to say, both MUST know what they’re talking about. Although I consider these questions as a thorough verbal test for the candidate’s knowledge, in most cases, when he or she passes this phase I will also ask them to perform an actual hands-on lab based on my written exercises. I might also include these in a future part of this session.
I have deliberately left out the answers to these questions. I want YOU to research them and take the time to actually learn these topics if you don’t know them already.
Most sub topics start off with relatively easy questions where the candidate is supposed to demonstrate their knowledge on that topic. A few sentences will be enough to show their (lack of) knowledge on the topic.
As always, your comments and feedback are more than welcome. Use the “Comment” form below to send them in. If you’re using this interview question sample in your own environment please drop me a line telling me how it works for you.
