You need to know that your potential hire is not afraid of failure or of trying new ways to do things that benefit the company. This question can help an interviewer see how adaptable a potential systems administrator might be and what skills they could use to take care of various tech issues. What to look for in an answer:
Example: "In my experience, it is rare that the first attempt at something like this is successful. I always try to plan for at least two backup scenarios as necessary.

Can you tell me a bit about what a DC is, why it is important and when you should or should not restore it?
This question helps an interviewer test the basic knowledge of the potential candidate. A good systems administrator should know already what a DC is, how it functions and when backups should be avoided. Answers to this query should give you some insight into the hire's thought processes and theoretical knowledge of how networked electronics systems operate. What to look for in an answer:
