📅 90-Day DEA-C01 Study Plan

A comprehensive 90-day plan for building deep AWS data engineering knowledge before the DEA-C01 exam.

Prerequisites

  • Basic cloud concepts and beginner AWS experience
  • 30-60 minutes of study time per day
  • AWS account access for optional hands-on labs

Study Schedule

Month 1 (Days 1-30)Data Foundations and Domain 1
  • Week 1: AWS data services overview — S3, Glue, Kinesis, Redshift, Athena, EMR, DynamoDB
  • Week 2: AWS Glue deep dive — crawlers, Data Catalog, ETL jobs, DataBrew, job bookmarks, DynamicFrames
  • Week 3: Streaming ingestion — Kinesis Data Streams, Firehose, Data Analytics, MSK, Lambda triggers
  • Week 4: DMS, data formats (Parquet, ORC, Avro), compression, and batch pipeline patterns
  • End of month: Domain 1 quiz and Glue + Kinesis flashcards
Month 2 (Days 31-60)Data Stores, Operations, and Pipelines
  • Week 5: S3 data lake design — partitioning, lifecycle, Intelligent-Tiering, event notifications
  • Week 6: Redshift — architecture, distribution, sort keys, COPY, Spectrum, Serverless, WLM
  • Week 7: Lake Formation — fine-grained access, LF-Tags, governed tables, cross-account sharing
  • Week 8: Pipeline orchestration — Step Functions, MWAA, Glue workflows, CloudWatch monitoring
  • End of month: Domains 2-3 mixed quiz and notes review
Month 3 (Days 61-90)Security, Governance, and Exam Readiness
  • Week 9: IAM for data services, KMS encryption, Lake Formation permissions
  • Week 10: CloudTrail, Macie, data governance, Athena optimization, QuickSight
  • Week 11: Full mock exam #1 and detailed review of every wrong answer
  • Week 12: Full mock exam #2, flashcards, cheat sheets, and weak-domain review
  • Final days: One light mixed quiz and rest before exam day

Study Tips

💡

Build a hands-on data pipeline with Glue, S3, and Athena to internalize the ETL workflow.

💡

Create a comparison table: when to use Glue vs EMR vs Lambda vs Kinesis.

💡

Turn wrong answers into study flashcards for spaced repetition.

💡

Domain 1 (34%) and Domain 2 (26%) make up 60% of the exam — prioritize them.
