- Practice switching between portals and finding settings quickly

- Time management is crucial - don't spend more than 2 minutes on any single question initially
Stay Current with Updates

- Practice creating custom sensitive information types for DLP
- Learn the eDiscovery workflow from case creation through export and review

Exam day checklist
- Arrive at the testing center 15 minutes early or log in to online proctoring 30 minutes before
- Read each question twice, paying attention to qualifiers like 'NOT', 'EXCEPT', or 'LEAST'
- Use the mark for review feature liberally - your first instinct isn't always correct
- Watch for questions that ask for multiple correct answers - the question will explicitly state this
- If you encounter a case study, read all questions first before diving into the scenario details
- For lab simulations, verify your configuration before moving on - you cannot return to labs
- Manage your time: aim for 2 minutes per question, giving you time for review
- Don't panic if you see unfamiliar terminology - use context clues and elimination strategies
- Remember that Microsoft uses 'best answer' logic - multiple options may work, but one is optimal
- If completely stuck, make an educated guess and move on - there's no penalty for wrong answers
- Use the last 15 minutes to review flagged questions and verify you answered all questions
- Take the optional break if offered halfway through - use it to clear your mind and refocus
