Official Google Cloud Certified Professional Data Engineer Study Guide. Dan Sullivan

terminology and core concepts and common sources of error in machine learning. Machine learning is a broad discipline with many areas of specialization. This chapter provides you with a high-level overview to help you pass the Professional Data Engineer exam, but it is not a substitute for learning machine learning from resources designed for that purpose.

      Chapter 12: Leveraging Prebuilt ML Models as a Service This chapter describes Google Cloud Platform options for using pretrained machine learning models to help developers build and deploy intelligent services quickly. The services are broadly grouped into sight, conversation, language, and structured data. These services are available through APIs or through Cloud AutoML services.

      Interactive Online Learning Environment and TestBank

Learning the material in the Official Google Cloud Certified Professional Engineer Study Guide is an important part of preparing for the Professional Data Engineer certification exam, but we also provide additional tools to help you prepare. The online TestBank will help you understand the types of questions that will appear on the certification exam.

      The sample tests in the TestBank include all the questions in each chapter as well as the questions from the assessment test. In addition, there are two practice exams with 50 questions each. You can use these tests to evaluate your understanding and identify areas that may require additional study.

      The flashcards in the TestBank will push the limits of what you should know for the certification exam. Over 100 questions are provided in digital format. Each flashcard has one question and one correct answer.

      The online glossary is a searchable list of key terms introduced in this Study Guide that you should know for the Professional Data Engineer certification exam.
