AB-620 exam format: questions, score and cost

Here is what Microsoft publishes about the AB-620 format, and what it leaves unstated.

Languages: English, Arabic (Saudi Arabia), Chinese (Simplified), Chinese (Traditional), French, German, Indonesian, Italian, Japanese, Korean, Portuguese (Brazil), Russian and Spanish. If your language is not offered, you can request an extra 30 minutes.

A newer exam than most

Microsoft’s certification page states that “the Practice Assessment for this exam is not currently available” and that practice assessments “are usually available within 8 weeks of the exam being out of beta and generally available”.

That single sentence tells you two useful things. First, there is no official Microsoft practice assessment to lean on yet, unlike established exams. Second, the exam is recent enough that third-party material is thin and community reports are scarce. Prepare from the skills outline itself rather than assuming a course covers it.

Question types

Microsoft exams mix single and multiple choice, drag-and-drop ordering, dropdown completions, yes/no statement series and case studies. Microsoft also notes that this exam “may have interactive components”.

For yes/no series you generally cannot return once answered, so read the shared scenario carefully before committing to the first statement.

The passing score is scaled

700 out of 1000 is not 70% of questions correct. Microsoft scales scores and weights questions differently, so there is no fixed count that guarantees a pass. Aim for consistent 80%+ on realistic practice material.

Preview features

Most questions cover generally available features, though Microsoft notes commonly used preview features can appear. That caveat matters more here than on most exams: Copilot Studio, MCP support and A2A are all moving quickly, and parts of the outline describe capabilities that were preview very recently.

Domain weighting

Integration is the heaviest and the most technical. Test and manage is the smallest but the most neglected — application lifecycle management, solutions, environment variables and Power Platform Pipelines are unglamorous and reliably examined.

What the format means for revision

Two hours for an exam whose largest domain is integration means you will meet scenario questions rather than definition questions. Expect to be given a business requirement — connect to ServiceNow, hand a task to a Foundry agent, let an agent operate an application with no API — and asked which mechanism fits.

That rewards a specific kind of preparation: for every integration mechanism in the outline, be able to say in one sentence what problem it solves and what it needs to work. Rote memorisation of menu paths is much less useful than knowing why you would reach for MCP over a custom connector.

If you fail

You can retake 24 hours after a first failed attempt; waiting periods increase for later attempts. Use the score report’s three bars to decide what to fix before rebooking.

Renewal

This is an associate-level certification, so it expires after a year and is renewed by passing a free online assessment on Microsoft Learn. The renewal is unproctored and takes far less time than the exam, but it is a recurring commitment.

Booking

Book through the Microsoft certification page, which hands you to Pearson VUE. Register with a personal Microsoft account rather than a work account — Microsoft warns that exam records tied to an organisational account are lost, and unrecoverable, if you leave that organisation.
