Prepare for Microsoft Exam 70-774—and help demonstrate your real-world mastery of performing key data science activities with Azure Machine Learning services. Designed for experienced IT professionals ready to advance their status, Exam Ref focuses on the critical thinking and decision-making acumen needed for success at the MCSA level.

Focus on the expertise measured by these objectives:
• Prepare data for analysis in Azure Machine Learning and export from Azure Machine Learning
• Develop machine learning models
• Operationalize and manage Azure Machine Learning Services
• Use other services for machine learning

This Microsoft Exam Ref:
• Organizes its coverage by exam objectives
• Features strategic, what-if scenarios to challenge you
• Assumes you are familiar with Azure data services, machine learning concepts, and common data science processes


The 70-774 exam focuses on the features and functionalities available to properly perform data science activities using Azure Machine Learning. It covers the tasks needed to properly prepare data to be analyzed in Azure Machine Learning and how to understand and find the key variables that are describing data behavior. This book also covers how to to develop Machine Learning Models, identifying the best suited algorithm, and describing the train and validation steps that need to be taken to obtain the best in class models. The book also covers how to deploy, manage, and consume Azure Machine Learning Models, and how to leverage other services.

This book is focused on data scientists or analysts who are interested in learning about the use of Azure cloud services to build and deploy Azure Machine Learning Models. We also cover how to build intelligence systems that can complement other services like Cognitive Services APIS, templates from the Cortana intelligence Gallery, HDInsight, or R Server services.

This book covers every major topic area found on the exam, but it does not cover every exam question. Only the Microsoft exam team has access to the exam questions, and Microsoft regularly adds new questions to the exam, making it impossible to cover specific questions. You should consider this book a supplement to your relevant real-world experience and other study materials. If you encounter a topic in this book that you do not feel completely comfortable with, use the “Need more review?” links you’ll find in the text to find more information and take the time to research and study the topic. Great information is available on MSDN, TechNet, and in blogs and forums.

Organization of this book

This book is organized by the “Skills measured” list published for the exam. The “Skills measured” list is available for each exam on the Microsoft Learning website: Each chapter in this book corresponds to a major topic area in the list, and the technical tasks in each topic area determine a chapter’s organization. If an exam covers six major topic areas, for example, the book will contain six chapters.

Preparing for the exam

Microsoft certification exams are a great way to build your resume and let the world know about your level of expertise. Certification exams validate your on-the-job experience and product knowledge. Although there is no substitute for on-the-job experience, preparation through study and hands-on practice can help you prepare for the exam. We recommend that you augment your exam preparation plan by using a combination of available study materials and courses. For example, you might use the Exam ref and another study guide for your ”at home” preparation, and take a Microsoft Official Curriculum course for the classroom experience. Choose the combination that you think works best for you.

Note that this Exam Ref is based on publicly available information about the exam and the author’s experience. To safeguard the integrity of the exam, authors do not have access to the live exam.
