Exam Strategy (150 minutes / 60 questions)¶

Time Allocation: - First pass: 90 minutes (1.5 min/question) - Review flagged: 40 minutes - Final check: 20 minutes

Scenario Question Approach: 1. Read entire scenario (2 minutes) 2. Identify key requirements and constraints 3. Eliminate options that violate requirements 4. Consider trade-offs (cost vs performance vs security) 5. Choose BEST option for the scenario

Professional-Level Thinking: - Focus on enterprise scale and complexity - Consider business impact and risk - Think about operational complexity - Always consider compliance and governance - Evaluate total cost of ownership

Red Flags in Answers (Usually Wrong)¶

❌ Single point of failure in critical path
❌ Violates compliance requirements
❌ Excessive complexity with no clear benefit
❌ Ignores stated business constraints
❌ Not cost-effective for the scale
❌ Doesn't meet RTO/RPO requirements

Green Flags in Answers (Usually Correct)¶

✅ Multi-AD/multi-region for HA/DR
✅ Meets all stated requirements
✅ Balances cost with other requirements
✅ Uses managed services appropriately
✅ Implements security best practices
✅ Scalable and operationally efficient

Final Week Checklist¶

Completed 5+ full practice exams (avg score 85%+)
Reviewed all enterprise architecture patterns
Completed all critical hands-on projects
Can explain trade-offs for any design decision

Prepared exam day logistics
Well-rested and confident

Professional Architect Mindset: - Business outcomes over technical perfection - Risk management is key - Total cost of ownership matters - Operational excellence is non-negotiable - Everything fails - design for it

Remember: This is a PROFESSIONAL certification. Think like an enterprise architect, not just a technician.

Good luck! 🚀🏗️
