Requirements / Prerequisites
- Foundational AWS Knowledge: A solid understanding of core AWS services like EC2, S3, IAM, VPC, and basic networking concepts is essential, as these often underpin data engineering solutions.
- Prior Data Engineering Experience/Training: This course assumes you have already completed a comprehensive study program or possess practical experience in AWS data engineering, as its focus is on testing existing knowledge rather than teaching new concepts.
- Understanding of Data Concepts: Familiarity with fundamental data engineering principles, including ETL (Extract, Transform, Load) processes, data warehousing, data lakes, streaming data, batch processing, and database management systems, is required.
- Basic SQL Proficiency: A working knowledge of SQL is beneficial for understanding data manipulation, querying, and optimization within various AWS data services such as Redshift, Athena, and RDS.
- Commitment to Review: Dedication to meticulously review detailed explanations after each practice test, identify weak areas, and undertake additional study for reinforcement is crucial for maximizing learning.
Skills Covered / Tools Used (Knowledge Validated)
- Data Ingestion: Proficiency in selecting and implementing AWS services for ingesting various data types, including batch, streaming, and CDC (Change Data Capture) via services like Kinesis, MSK, DMS, and Snowball.
- Data Transformation: Expertise in transforming raw data into usable formats using AWS Glue (ETL jobs, DataBrew), AWS Data Pipeline, EMR (for Spark, Hive, Presto), and Step Functions for orchestration.
- Data Storage & Management: Ability to design and manage robust data storage solutions using Amazon S3 (object storage), Amazon Redshift (data warehousing), Amazon RDS/Aurora (relational databases), DynamoDB (NoSQL), and Lake Formation for data lake governance.
- Data Processing & Analytics: Skill in employing AWS analytics services such as Amazon Athena (serverless querying), Amazon EMR (big data processing), Amazon QuickSight (business intelligence), and OpenSearch Service (log analytics).
- Data Security & Governance: Reinforced knowledge of securing data engineering workflows, including IAM for access control, KMS for encryption, network security (VPC, Security Groups), and Lake Formation for fine-grained access to data lakes.
- Monitoring & Optimization: Understanding how to monitor data pipelines using AWS CloudWatch and CloudTrail, troubleshoot issues, and optimize performance and cost effectiveness of data engineering solutions.
- Workflow Orchestration: Competence in orchestrating complex data workflows using AWS Step Functions and AWS Glue Workflows to create scalable and resilient data processing pipelines.
- Exam Strategy & Time Management: Enhanced ability to manage exam time efficiently, decipher complex question structures, and apply strategic thinking to select the most appropriate answer under pressure, directly tested by the practice exams.
