Subscribe to my YouTube channel that teaches you to apply Google Cloud to your projects and also prepare for the certifications: Check out the playlists I currently have for Associate Cloud Engineer, Professional Architect, Professional Data Engineer, Professional Cloud Developer, Professional Cloud DevOps Engineer, Professional Cloud Network Engineer, and Professional Cloud Security Engineer.

Immediately after the exam I do a memory dump as notes. Hence it is also quite unordered. This is a sanitized list that gives general topics and questions I encountered. The intention is not to give you the questions, but to give you topics that you can be prepared for. I was often stumped by some questions; hopefully you can be more prepared based on my experience. Wish you the very best!

Tough exam. I assumed this one would be easier because I spent more time preparing and I had the experience of the previous certifications. After the exam I went over the questions again to remind myself later what areas were covered — the answer is, everything. Zero direct questions. Every question was embedded in a situation/use case.

The Data Engineer exam was refreshed on March 29th. These are some extracted key points and links that others have posted. From what I am reading of others’ notes


  • Cloud Composer: added in new topics.
  • No case studies in new exam.
  • BigQuery: streaming data, quotas, and limits, ETL data verification, BigQuery ML, User Defined Functions.
  • Datastore: backup and migrate.
  • ML: I heard there is a little more ML. Scaling TensorFlow.
  • PubSub: migrating from Kafka, debugging via Stackdriver.
