MB-800 Cheat Sheet 2026: One-Page Review of Must-Know Facts

TL;DR
  • MB-800 requires a scaled score of 700 out of 1,000 - not 70% of questions correct.
  • Configure financials and Perform Business Central operations each carry 30-35%, the two heaviest domains.
  • The exam runs 100 minutes via Pearson VUE test center or OnVUE remote proctoring.
  • Certification is valid one year; renew free online during the six months before expiry.

What MB-800 Actually Certifies

MB-800 is the exam code behind the Microsoft Certified: Dynamics 365 Business Central Functional Consultant Associate credential, issued by Microsoft. Passing exam MB-800, titled "Microsoft Dynamics 365 Business Central Functional Consultant," earns you the named Associate certification. If you're still mapping out what the letters and numbers mean before diving into study material, the primer at What Is MB-800? and the deeper explainer at MB-800 Meaning are good starting points. This cheat sheet assumes you already know the basics and just want the must-know facts condensed onto one page.

Scope Reminder: This exam is entirely about configuring and operating Business Central - general ledger setup, sales and purchasing workflows, inventory, and day-to-day operational tasks. It is not a developer exam and does not test AL code or extension development.

Exam Mechanics at a Glance

Before you book a seat, memorize these logistics. They rarely get the attention they deserve, but they shape how you pace the exam itself.

  • Delivery: Pearson VUE test center or OnVUE remote-proctored, from your own machine.
  • Duration: 100 minutes total, which may include interactive, scenario-based components rather than pure multiple choice.
  • Reference tool: Microsoft Learn is accessible inside the exam interface, but with restrictions - no Q&A forums, no Practice Assessments, no personal profile access, and no general browsing.
  • No personal notes: You cannot bring in your own reference sheets, digital or physical.
  • Timer never pauses: Looking things up in Microsoft Learn or taking a break still burns exam time.
  • No revisiting after breaks: Once you step away and return, questions you already saw are locked - you cannot go back and change answers.

Key Takeaway

Practice navigating Microsoft Learn's restricted in-exam view before test day - fumbling with an unfamiliar reference tool wastes minutes you can't get back since the clock keeps running.

Domain Breakdown Cheat Sheet

MB-800 has four domains, and two of them dominate the weighting. Treat this table as your quick-reference anchor, then dig into the full explanation in MB-800 Exam Domains 2026: Complete Guide to All 4 Content Areas.

DomainWeightCore Focus
Set up Business Central20-25%Company setup, security, number series, roles
Configure financials30-35%General ledger, chart of accounts, dimensions, bank/cash
Configure sales and purchasing10-15%Customers, vendors, pricing, order processing
Perform Business Central operations30-35%Inventory transactions, Copilot/agent features, day-to-day workflows

Set up Business Central (20-25%)

Covers foundational configuration decisions made before the system goes live.

  • Company setup and posting groups
  • Security auditing and permission sets
  • Number series and role center configuration

Configure financials (30-35%)

The single heaviest domain - expect deep coverage of accounting configuration.

  • General ledger, chart of accounts, and dimensions
  • Bank account and cash flow setup
  • Fixed assets and budgeting basics

Configure sales and purchasing (10-15%)

The lightest domain by weight, but still tested in scenario form.

  • Customer and vendor record setup
  • Pricing agreements and discounts
  • Order-to-cash and procure-to-pay flows

Perform Business Central operations (30-35%)

Tied for heaviest weight, and increasingly focused on newer platform capabilities.

  • Inventory transactions and item tracking
  • Copilot and agent enablement scenarios
  • Routine operational tasks across modules

Notice that Copilot and agent enablement, security auditing, and inventory transactions are explicitly named as current objectives on the official skills outline effective through June 30, 2026. These are not filler topics - expect them to show up as scenario-based questions rather than simple definitions.

Scoring and Passing Score

This trips up a lot of candidates who assume exams work on a percentage basis. MB-800 uses a scaled score of 700 on a 1-1,000 scale, not "70% of questions correct." Different questions can carry different weight, so you cannot back-calculate your result from how many items you think you answered correctly. For the full mechanics of how scaled scoring works and why it matters for your prep strategy, read MB-800 Passing Score 2026: Exactly What You Need to Pass.

Don't Chase a Percentage: Because scoring is scaled rather than raw-percentage, focus your energy on mastering the heavily-weighted domains (Configure financials and Perform Business Central operations) rather than trying to guess a magic number of correct answers needed.

Registration, Retakes, and Attempts

Recommended preparation for MB-800 is hands-on: real Business Central implementation, configuration, and business-process experience rather than pure theory. If you're unsure whether you meet the practical background Microsoft expects, check MB-800 Requirements 2026: Eligibility, Prerequisites & How to Qualify before you register.

Retake rules are straightforward but easy to forget mid-panic after a fail:

  • First failed attempt: wait 24 hours before retaking.
  • Any subsequent failed attempt: wait 14 days.
  • Maximum of five attempts within any 12-month period.

If budget planning or fee mechanics are part of your decision-making, the breakdown in MB-800 Certification Cost 2026: Complete Pricing Breakdown and scheduling guidance in MB-800 Exam Dates 2026: Testing Windows, Deadlines & Scheduling cover what to expect before you book through Pearson VUE.

Renewal in One Year

Unlike some Microsoft certifications with longer validity windows, the Business Central Functional Consultant Associate credential is valid for one year from the date you earn it. Renewal, however, is designed to be painless:

  • Renewal happens through a free, online, unproctored, open-book assessment.
  • You can take it during the six months before your certification expires.
  • Passing extends your validity one year from the existing expiration date - it doesn't reset the clock to the renewal date.
  • The separate English renewal assessment itself was updated August 31, 2026, so make sure you're studying against the current version.

Key Takeaway

Set a calendar reminder about seven months after you pass MB-800 so you don't miss the six-month renewal window and let the credential lapse.

A Fast Review Schedule

If you're using this cheat sheet as a final-week refresher rather than a first-time study plan, allocate your remaining hours by domain weight, not evenly across all four areas. The full multi-week plan lives in MB-800 Study Guide 2026: How to Pass on Your First Attempt, but here's a compressed version for a short runway.

Week 1

Configure Financials + Setup

  • Drill general ledger, dimensions, and posting groups
  • Review security auditing and role setup scenarios
Week 2

Perform Business Central Operations

  • Practice inventory transaction scenarios end to end
  • Study Copilot and agent enablement workflows
Week 3

Sales and Purchasing + Full Review

  • Cover pricing, order processing, and vendor setup
  • Run a timed practice session simulating the 100-minute limit

Because Configure financials and Perform Business Central operations together account for well over half the exam weight, spending two of your three remaining weeks there is a deliberate, math-based choice - not guesswork.

Who Actually Hires MB-800 Holders

This credential targets functional consultants who configure and support Business Central implementations for organizations running Microsoft's mid-market ERP. That typically means Microsoft partner firms doing implementation and support work, in-house ERP administrators at companies running Business Central, and consultants transitioning from other ERP or accounting backgrounds into the Microsoft ecosystem.

Frequently Asked Questions

Is MB-800 scored as a percentage of correct answers?

No. MB-800 uses a scaled score on a 1-1,000 range, and passing requires reaching 700. Questions can carry different weight, so a raw percentage of correct answers doesn't map directly to the scaled score.

Which domain should I prioritize if I'm short on time?

Configure financials and Perform Business Central operations are tied as the largest domains at 30-35% each, so they deserve the majority of your remaining review time over Set up Business Central (20-25%) and Configure sales and purchasing (10-15%).

Can I use my own notes during the exam?

No. Personal notes are not permitted. You do get restricted access to Microsoft Learn during the exam, but Q&A forums, Practice Assessments, your profile, and general browsing are all blocked, and the timer keeps running while you look things up.

How long is the certification valid, and how do I renew it?

It's valid for one year. You renew through a free, online, unproctored, open-book assessment available during the six months before expiry. Passing extends your validity one year from the original expiration date, not from the renewal date.

What happens if I fail the exam more than once?

After a first failed attempt, you wait 24 hours to retake. After any subsequent failure, the wait is 14 days. You're capped at five total attempts within a rolling 12-month period.
