The Microsoft Certification Exam

The Azure Cosmos DB Developer Specialty (DP-420) exam consists of approximately 45 questions (the exact number varies slightly from one test to another) and you have 100 minutes to complete it. You must achieve a passing score of 700 out of 1000 points to pass.

The exam mixes several question formats to assess your knowledge. You can expect the classic single-answer multiple-choice items, multiple-select questions where two or more options are correct, and drag-and-drop questions. There are also occasional yes/no questions.

You will also get case-study or scenario-based questions that present business problems requiring you to choose the best solution. And you can expect hands-on lab questions where you must perform specific tasks in a live Azure environment.
