What types of databases do you work with?

The purpose of this question is to gain a better understanding of your background. There are many different types of databases you can administer. The interviewer is attempting to determine if you have direct experience working with the type of databases they use in their organization. The research you perform before the interview should indicate the type of databases they use. Your answer should either demonstrate that you have experience with these or discuss how you can adapt to their databases using your experience managing other types.
