Tested myself on Exam 70-442 (Designing and Optimizing Data Access by Using Microsoft SQL Server 2005) Objective 4 (Designing a Transaction Strategy) and received 100%.  However, I've still got a bit of study to do, specifically:

1. Manage concurrency by selecting the appropriate transaction isolation levels
2. Design the locking granularity level
3. Design transaction scopes
4. Design code that uses transactions
   Optimization using Single Phase Commit and Promotable Single Phase Notification
   Committing a Transaction in Single-Phase and Multi-Phase
   Enlisting Resources as Participants in a Transaction
   Transaction Management Escalation
