  3. Understand supervised, unsupervised, and deep learning approaches

  4. Learn AWS ML service landscape and when to use each

  5. SageMaker Core Services

  6. Focus on SageMaker Studio as the development environment
  7. Master data preparation with Data Wrangler and Processing
  8. Understand Feature Store for feature management
  9. Learn Glue ETL for data transformation

Phase 2: Model Development and Deployment (3-4 weeks)

  1. Training and Tuning
  2. SageMaker training jobs and instance selection
  3. Built-in algorithms and custom training containers
  4. Hyperparameter tuning strategies

  5. Model evaluation and experiment tracking

  6. Deployment and Pipelines

  7. Endpoint types: real-time, batch, serverless, async
  8. SageMaker Pipelines for ML workflows
  9. MLOps patterns with SageMaker Projects

  10. Deployment strategies: blue/green, canary

  11. Hands-on Practice

  12. Build end-to-end ML pipelines
  13. Deploy models with different inference options
  14. Configure Model Monitor for drift detection
  15. Practice with SageMaker Studio notebooks

Phase 3: Exam Preparation (2 weeks)

  1. Monitoring, Security, and GenAI
  2. Model Monitor capabilities and drift types
  3. IAM roles and VPC configuration for SageMaker
  4. Amazon Bedrock and foundation models

  5. Responsible AI with SageMaker Clarify

  6. Practice and Review

  7. Take multiple practice tests
  8. Review incorrect answers thoroughly
  9. Focus on weak domains

Exam Tactics

Question Strategy

  1. Read Carefully: Identify the ML lifecycle stage the question addresses
  2. Eliminate: Remove obviously incorrect answers first
  3. SageMaker First: When in doubt, the SageMaker-native solution is usually correct
  4. Cost vs Performance: Balance inference cost with latency requirements
  5. Managed Services: Prefer managed services over custom implementations

Domain Focus by Weight

  • Data Preparation for ML (28%) - Largest domain, prioritize this
  • ML Model Development (26%) - Second priority, heavy on SageMaker training
  • Monitoring, Maintenance, and Security (24%) - Third priority
  • Deployment and Orchestration (22%) - Important for MLOps focus

Common Patterns

  • Data Prep: S3 -> Glue ETL -> Feature Store -> Training
  • Training: SageMaker Training Job with Spot instances -> Model Registry
  • Deployment: Model Registry -> Pipeline -> Endpoint with auto-scaling
  • Monitoring: Model Monitor -> CloudWatch Alarm -> Retraining Pipeline
  • GenAI: Bedrock -> Knowledge Base -> Agent -> Guardrails

Time Management

  • 2 minutes per question average (85 questions, 170 minutes)
  • Flag and move: Don't spend too long on difficult questions
  • Review time: Reserve 20 minutes for flagged questions
  • Quick wins: Answer easy questions first

Common Pitfalls

Study Mistakes

  • Focusing too much on ML theory and not enough on AWS services
  • Skipping hands-on SageMaker practice
  • Not understanding the difference between endpoint types
  • Ignoring Data Wrangler and Feature Store
  • Underestimating the monitoring and security domain

Exam Mistakes

  • Not reading questions carefully - missing "MOST cost-effective" or "LEAST effort"
  • Choosing custom solutions when SageMaker built-in features exist
  • Confusing SageMaker Processing with SageMaker Training
  • Not considering Feature Store for feature sharing scenarios
  • Overlooking Bedrock for generative AI questions

Progress Tracking

Weekly Milestones

  • Week 1-2: Master data ingestion, Glue ETL, and Data Wrangler
  • Week 3-4: Complete Feature Store and data quality checks
  • Week 5-6: Finish SageMaker training, tuning, and model registry
  • Week 7-8: Complete deployment, pipelines, and MLOps
  • Week 9: Study monitoring, security, and Bedrock
  • Week 10: Practice exams and final review

Self-Assessment Questions

  • Can I design a data pipeline from S3 through Glue to Feature Store?
  • Do I understand SageMaker training job configuration and instance selection?
  • Can I choose the right endpoint type for different inference requirements?
  • Do I know how to set up Model Monitor for drift detection?
  • Can I build an end-to-end ML pipeline with SageMaker Pipelines?
  • Do I understand IAM roles and VPC configuration for SageMaker?
  • Can I explain when to use Bedrock vs SageMaker for ML workloads?
