Exam Strategy¶

Time Management (105 min / 60 questions): - First pass: 60 minutes (1 min/question) - Review flagged: 30 minutes - Final review: 15 minutes

Question Approach: - Read scenario carefully, identify requirements - Consider cost, performance, security, HA - Eliminate obviously wrong answers - Choose BEST option (not just correct) - Flag and move on if unsure

Common Question Keywords: - "Most cost-effective" → Consider pricing models - "Highest security" → Look for KYOK, Security Zones - "Best performance" → Consider dedicated resources - "High availability" → Multi-AD, fault domains - "Disaster recovery" → Cross-region, backups

Week Before Exam¶

Take final practice exam (90%+ target score)
Review all architecture patterns
Quick review of all services and use cases
Prepare exam day logistics
Get adequate sleep (7-8 hours)

Success Formula: 40% Hands-on Labs + 40% Practice Questions + 20% Theory

Remember: Architecture is about trade-offs. Always consider cost, performance, security, and availability in your designs!

Good luck! 🏗️
