The short version
AI-300 gives you 120 minutes, is proctored, and is offered in English. You pass with a score of 700 or higher on a scale of 1 to 1,000. Microsoft does not publish the number of questions. Everything below comes from Microsoft Learn pages checked on October 18, 2026, so confirm the details when you book.

The question count is not fixed. Microsoft says the number can change as exams are updated and that most of its exams contain between 40 and 60 questions. Treat that as a general range, not a promise for AI-300.
Exam time and seat time
Microsoft separates exam time from seat time. Exam time is the clock on your questions. Seat time includes the instructions, the candidate agreement, and the feedback survey at the end. For role-based exams that may contain labs, Microsoft’s general table gives 120 minutes of exam time and 140 minutes of seat time. The AI-300 page lists 120 minutes, so plan for roughly 140 minutes in total, and read the start screens of your exam for the exact numbers.
Scoring
Your result is a scaled score from 1 to 1,000, and 700 is the pass line. Scaled does not mean 70 percent. Microsoft converts your performance to a common scale so different versions of the exam are comparable. Do not try to compute a percentage from it. You also cannot tell which items were scored, because some items on an exam are unscored. Many questions have several parts, and you can get partial credit.
There is no penalty for guessing, so answer every question. After the exam you get a score report with your overall score, pass or fail, and a bar chart of your performance in each skill area. It shows no per-question detail, but it is useful when you plan a retake.
Question types
Microsoft deliberately does not list the question types for each exam. What it does say is that the exam may include interactive components, and that its exam sandbox lets you try the interface and the question types you may meet, such as multiple choice, drag and drop, hot area, build list, and case studies. Open the sandbox once before exam day so the buttons are not a surprise. Our exam question types page explains how to approach each style.
Do not expect memory-only questions. Typical AI-300 items describe a situation, such as a deployment that needs a safe rollout or a network that must stay private, and ask which feature, setting, or command fits.
Microsoft Learn during the exam
Microsoft says you can open Microsoft Learn in a side panel during associate and expert exams, but not on fundamentals exams. You can reach most of learn.microsoft.com, but not Q&A, practice assessments, or your profile. No extra time is added and the clock keeps running. It is meant for the occasional lookup. If you use it on every question, you will run out of time, and Microsoft says that is by design. Check your own start screen to confirm it applies to your session.
Breaks
You can take unscheduled breaks, but the clock keeps running. Microsoft built five minutes into the exam time for this. When you start a break, you cannot go back to questions you saw before it, even unanswered ones. So answer or mark everything first. You cannot break in the middle of a lab or a problem-solution question set. Use the exam interface to start a break, and stay in camera view otherwise.
Delivery and identity checks
AI-300 is proctored. You book through Pearson VUE, either at a test center or online, depending on what the booking page offers in your region. Use a personal Microsoft account when you register, not a work or school account, because Microsoft warns that records tied to an organizational account can be lost if you leave the organization.
Retakes
- If you fail, you can retake after 24 hours.
- Later retakes need a 14-day wait between attempts.
- You can take the same exam at most five times in 12 months, counted from the first attempt.
- You cannot retake an exam you passed unless the certification has expired.
Microsoft may waive the wait only for internet or equipment problems documented with a Pearson VUE case.
Renewal
The Machine Learning Operations Engineer Associate credential is an associate-level certification, which Microsoft says expires annually. You can renew for free by passing an online, unproctored, open-book assessment on Microsoft Learn during the six-month window before expiry. Passing extends the credential by one year.
Accommodations and language
If you use assistive devices, need extra time, or need changes to the exam experience, request an accommodation before you register. Microsoft also notes that if an exam is not available in your preferred language, you can ask for 30 extra minutes. Since AI-300 is listed in English only, that matters if English is not your first language.
