Does anybody know how to calculate the number of necessary domain databases? My MS Press book is not useful in that. I?d appreciate it if someone could help me out with this question. 
The recommended Windows NT domain database size is 40 MB. Performance is likely to suffer if the domain database grows beyond this limit. Your company plans to have 50,000 user accounts, 40,000 computer accounts and 500 group accounts on the company-wide network. What is the minimum required number of domain databases?
- A. Two
- B. Three
- C. Four
- D. Five
Answer: A
- E. One
