I don't mean to be rude, but your list of questions is a perfect example of why this type of test would be meaningless.

* What is a data base - Are you asking what type of military base stores data? Or did you mean database?

* What is personal identifiable identification and why does it matter? - Do you mean PII (personally identifiable information)? Or are you talking about a driver's license?

* What does a walled garden mean - Are you talking about what is in my back yard? What is around a castle? Or Apple's App Store?
