Exam DP-300 Administering Relational Databases on Microsoft Azure – Study Guide



If you are interested in getting the new Microsoft role-based certification “Azure Database Administrator Associate” you only have to take the exam (DP-300. Administering Relational Databases on Microsoft Azure) so I’ve prepared a study guide that includes all the areas and topics that will be evaluated as well as links to the official documentation and learning portal.
