Practice the decisions behind reliable AWS data pipelines with 150 original questions for AWS Certified Data Engineer - Associate (DEA-C01). Cloudpuz Academy provides two distinct 75-question sets with explanations for the correct answer and every distractor. The scenarios ask you to identify suitable services, diagnose pipeline behavior, and recognize the tradeoffs behind a proposed change.

The complete bank follows the DEA-C01 domain weights: Data Ingestion and Transformation (34%), Data Store Management (26%), Data Operations and Support (22%), and Data Security and Governance (18%). Questions cover streaming and batch ingestion, replay and idempotency, Spark and SQL transformations, orchestration, analytical storage, cataloging, schema evolution, quality checks, observability, access control, encryption, and data governance. Selected scenarios also address vector storage and validation of LLM-assisted data processing.

Use the first test to identify gaps in your understanding. Afterward, read every option explanation and note which requirement makes an answer appropriate. Review the relevant AWS documentation, then use the second independent set to check progress. Working knowledge of SQL, ETL concepts, and core AWS services is recommended. An AWS account is not required to take these tests, though practical exercises can strengthen your understanding.

Each test contains 75 single-answer multiple-choice questions, allows 100 minutes, and uses an 80% study target. These are course practice settings, not the official AWS exam duration or scaled passing score. The actual AWS exam can also include multiple-response questions. This course provides practice tests and written explanations; it does not contain video lectures or hands-on labs.

Every question is independently written learning material. The course contains no actual, recalled, leaked, or copied certification exam questions. Cloudpuz Academy is independent of AWS, and AWS does not endorse this course. Always consult the current official exam guide because objectives and services can change. A practice score or course completion does not guarantee certification success.
