Preparing for the Google Cloud Professional Data Engineer Certification?
This course provides the most updated, 2025-ready practice tests aligned with both:

• Google’s Standard Exam Guide
• Google’s Renewal Exam Guide

The practice tests mirror real exam question patterns and cover every domain defined by Google Cloud—including pipeline design, data governance, security, analytics, ML readiness, storage planning, and workload optimization.

You will learn to design, build, maintain, and optimize complete data solutions using BigQuery, Dataflow, Dataproc, Cloud Storage, Dataplex, AlloyDB, Bigtable, Pub/Sub, Cloud Composer, and Vertex AI.

Every question includes a clear explanation, teaching not only the correct answer—but also why the other options are incorrect.

This course gives you the skills, exam readiness, and confidence to pass on the first attempt.
