🎯 How to Use These Cheatsheets

The Night Before Exam

1. Start with Final Exam Tips - Overview and strategy
2. Review highest-weight domains first: Domain 1 (22%) → Domain 2 (17%) → Domain 6 (17%)
3. Focus on “Key Points” and “Common Mistakes” sections in each cheatsheet
4. Practice CLI commands from each domain
5. Review scenario patterns and recognition triggers

Day of Exam

1. Quick scan of Final Exam Tips (10 minutes)
2. Review domain weights and time allocation
3. Mental checklist of key concepts per domain

• Cross-account access methods
• Load balancer type selection (ALB vs NLB vs GWLB)
• IAM policy evaluation logic

💡 Study Tips

Effective Review Strategy

1. Skim entire cheatsheet (5 minutes per domain)
2. Deep dive on weak areas (focus on “Common Mistakes”)
3. Practice scenario recognition (read “Exam Scenarios”)
4. Review CLI commands (muscle memory for syntax)
5. Final mental walkthrough of key concepts

Time Management

• Total exam time: 180 minutes (3 hours)
• Average per question: 2.7 minutes
• Strategy: First pass (90 minutes) → Review flagged (60 minutes) → Final check (30 minutes)

🎯 Success Checklist

Before entering the exam, ensure you can quickly explain:

• Cross-account IAM role assumption process
• Difference between blue/green and rolling deployments
• When to use ALB vs NLB vs GWLB
• Multi-AZ vs Read Replica use cases
• EventBridge event routing patterns
• CloudFormation stack dependencies and exports
• Lambda error handling and DLQ configuration
