Microsoft Implementing Microsoft Azure Cosmos DB Solutions (70-777) — Questions Candidates Actually Ask

The 70-777 exam, officially known as Microsoft Implementing Microsoft Azure Cosmos DB Solutions, is the Microsoft test that leads to the MCSA certification at the Specialty level. Passing it validates the skills employers expect from a certified professional. It is also associated with related credentials such as MCSA: Cloud Platform and Infrastructure, MCSA: Data Management and Analytics.

The 70-777 exam contains 40-60 questions, and you have 120 minutes to complete them. Work out your per-question pace before test day, and flag slow items instead of stalling on them — time pressure, not knowledge, sinks many first attempts. Timed mock exams in the Actual4Exams test engines are the most reliable way to build that rhythm.

The passing score for the 70-777 exam is 700/1000, and the official registration fee is USD 165. If you miss the mark, a retake means paying the full fee again, so book your seat only when you are ready. A practical benchmark: score consistently above the passing line on timed practice tests before scheduling the real exam.

No formal prerequisite exam. Intended for developers and architects with knowledge of Azure Cosmos DB, partitioning, replication, resource governance, and the Cosmos DB SQL API.
