The 70-357日本語 exam is the official Microsoft exam behind Microsoft Developing Mobile Apps (70-357日本語版) — passing it earns you the MCSA: Universal Windows Platform, MCSD: App Builder certification, a credential positioned at the Professional level. It is built for candidates who want to validate the skills measured by Microsoft Developing Mobile Apps (70-357日本語版). Depending on your track, the exam is also linked to the MCSA: Universal Windows Platform and MCSD: App Builder certifications, so one pass can move you toward more than one Microsoft credential.
The 70-357日本語 exam presents 40-60 questions to be completed within 150 minutes. That pace leaves little room for second-guessing: read each question carefully on the first pass, flag the ones you want to revisit, and keep moving instead of stalling on a single item. Before exam day, run at least one full timed session in the TestSimulate desktop or online test engine with a comparable question load — a steady rhythm under the clock is a trainable skill, and it is often what separates a pass from a near miss.
To pass the 70-357日本語 exam you need 700 out of 1000, and the official registration fee is $165 USD (varies by region). Keep in mind that a failed attempt means paying that fee again in full — retakes are not discounted. Given the cost, self-test before you book: if you can score comfortably above the passing mark on two or three consecutive timed TestSimulate practice tests, your budget is far better spent on the exam itself than on a retake.
Typically 2+ years of experience developing Windows apps with C# and XAML; familiarity with MVVM, Entity Framework, and authentication technologies; Visual Studio 2015+ recommended Because Microsoft revises its certification programs from time to time, treat this as a starting point rather than the final word. Confirm the current eligibility requirements on the official Microsoft exam page before you register.
