In this article, we will show how to prepare yourself for one of the important Microsoft Azure exams, DP-200: Implementing an Azure Data Solution certificate exam.
Implementing an Azure Data Solution certificate exam measures your intermediate-level knowledge in three main areas. This includes:
- How to implement data storage solutions, with relative questions weight in the exam up to 45%
- How to manage and develop data processing solutions, with relative questions weight in the exam up to 30%
- How to monitor and optimize data solutions, with relative questions weight in the exam up to 35%
With no official prerequisites for this exam, it is recommended, but not mandatory, to take the Microsoft Azure Fundamentals (AZ-900) exam if you are very new to Microsoft Azure world, and taking the Microsoft Azure Data Fundamentals (DP-900) if you are new to all Microsoft Azure data platform.
You can easily schedule the exam from the Implementing an Azure Data Solution certificate page. You need to pass both the Implementing an Azure Data Solution (DP-200) and the Designing an Azure Data Solution (DP-201) certificate exams in order to be certified as an Azure Data Engineer Associate. For more information about Microsoft Azure certificates, check It is time to specify your Microsoft Certifications path.
Microsoft Azure data engineers are responsible for all data-related design and implementation tasks, including provisioning the proper data storage service, ingesting streaming and batch data using the suitable mechanism, transforming data between different sources and storage types, implementing security requirements and data retention policies that meet the business requirements and identifying and fixing the performance bottlenecks during the implementation and running phases.
The Implementing an Azure Data Solution certificate exam is designed for the Microsoft Azure data engineers, data professionals, data architects, and business intelligence professionals, who will participate in the implementation phase of the data-related tasks for any solution that is implemented using the relational and non-relational Azure data services. These Microsoft Azure data services include Azure Cosmos DB, Azure SQL Database, Azure Synapse Analytics, Azure Data Lake Storage, Azure Data Factory, Azure Stream Analytics, Azure Databricks, and Azure Blob storage.
In order to prepare yourself for the Implementing an Azure Data Solution exam, you can go through the 7-module Implementing an Azure Data Solution learning path self-study course provided by Microsoft that helps you in getting the basic knowledge required to pass that exam.
If you are not interested in reading the pages and prefer to listen, you can subscribe to any online course such as Udemy, PLURALSIGHT or any other training provided by training sites and centers.
Take into consideration that this exam contains a large number of subjects. In order to pass the exam, you need to have enough knowledge in each subject, without going very deep in each subject. For me, I prefer to be fully prepared for the certificates exams and gain all the required knowledge in order to be able to provide training in the courses I am certified in and apply these skills in my customers’ sites. So, I will list all measured skills in this course and the official resource to study that subject.
