I would recommend to study Internet, database and Interface a lot. Again, the MSDN CD was extremely important to me. Know about replication and its variations. Some questions put scenarios where you have to evaluate the best replication engine. According to what I have noticed, online replications are better performed with SQL Server than Access.
Access is more suited to off-line synchronization.
Many questions about internationalization issues. Know well Unicode and its implementation. Also, classic questions about how to distribute or maintain a multi-language applications. CharNext and CharPrev was there. I marked it immediately.
