Suggest me some questions based on active directory for an interview?

Here are some good questions, that I've asked a lot of candidates in interviews?

1. What's the processing order for a GPO?

2. What are the FSMO roles and describe those?

3. How is the AD DB called? where is that file stored?

4. How can you migrate FSMO roles from one DC to another?

5. What's CG? How can you migrate GC from one DC to another?

And I can give you a lot more questions... If anyone will be able to answer these questions above, I guess he'll be OK

get clear with following key words

Forest

Domain controller

LDAP

get a practical hand on AD by installing a window server in a virtual player and - try to add and remove the user. learn how to reset the password. 

common question i got was "how many password by default are get remembered by active directory by checking "enforce password history" option?
