Recommended Study Timeline

Plan for approximately 10-16 weeks of dedicated study. Here is a suggested weekly breakdown:

• Week 1: Domain 1: Relational Databases. RDS engines (MySQL, PostgreSQL, Oracle, SQL Server), Aurora architecture
• Week 2: Domain 1: NoSQL Databases (DynamoDB design patterns, table structures, partition keys, sort keys)
• Week 3: Domain 1: Purpose-Built DBs. ElastiCache (Redis/Memcached), Neptune, DocumentDB, Keyspaces, QLDB, Timestream
• Week 4: Domain 2: Database Migration (DMS tasks, SCT conversions, homogeneous vs heterogeneous migrations)
• Week 5: Domain 2: Deployment Strategies (Blue/green deployments, Multi-AZ, read replicas, global databases)
• Week 6: Domain 3: Maintenance & Operations (Backups, snapshots, point-in-time recovery, patching, parameter groups)
• Week 7: Domain 3: Automation & Scaling (Auto Scaling for Aurora/DynamoDB, Lambda triggers, EventBridge automation)
• Week 8: Domain 4: Monitoring (CloudWatch metrics, Enhanced Monitoring, Performance Insights, slow query logs)
• Week 9: Domain 4: Troubleshooting (Connection issues, replication lag, capacity planning, deadlock analysis)
• Week 10: Domain 5: Encryption (KMS, TDE, SSL/TLS connections, encryption at rest and in transit)
• Week 11: Domain 5: Access Control (IAM database authentication, security groups, VPC endpoints, Secrets Manager)
• Week 12: Full Review: Practice exams, Hands-on labs, Weak areas, Exam logistics

Top Study Tips

1. Start with the official exam objectives. Download them from the AWS website and use them as your study checklist. Every exam question maps to a specific objective.

1. Use active recall over passive reading. Instead of re-reading notes, test yourself with practice questions after each study session. This dramatically improves retention.

1. Focus on heavily-weighted domains first. Domains with higher percentages appear more on the exam. Master these before moving to lower-weighted areas.

1. Build hands-on experience. Set up a lab environment and practice the skills you are studying. Hands-on experience is especially valuable for performance-based questions.

1. Take practice exams under real conditions. Time yourself, eliminate distractions, and simulate the exam environment. Review every wrong answer and understand why it was wrong.
