AB-731 Cheat Sheet 2026: Quick Reference
Every domain condensed to a table, plus the build-vs-buy-vs-extend decision and the Copilot/Foundry licensing models the exam tests directly.
Exam Snapshot
The domain weights, terminology, and reference links here come straight from Microsoft's official AB-731 exam page. We re-check them against our audited 500-question AB-731 practice bank so nothing drifts out of date.
1. Business Value of Generative AI (35-40%)
| Concept | Feature / Area | Quick note |
|---|---|---|
| Cost drivers | Tokens, ROI analysis | Weigh token cost against measurable business value, not price alone |
| Model types | Fine-tuned vs. pretrained | Fine-tuned = higher accuracy on niche terms, higher cost per token |
| Grounding | Retrieval-augmented generation (RAG) | Use for frequently changing, proprietary data — not a one-time fine-tune |
| Data quality | Representative datasets | Stale or unrepresentative data breaks outputs for new segments |
| Fabrications | Confidently wrong output | Require human review / citation checks, not a workaround |
| Bias | Skewed outputs | Distinct risk from fabrication — needs diverse training data, not just review |
| Prompt engineering impact | Output quality | Better prompts materially change result quality, not just phrasing |
| AI security | App, data, auth | Three distinct security surfaces to evaluate, not one generic "AI security" |
2. Microsoft AI Apps & Services (35-40%)
| Concept | Feature / Area | Quick note |
|---|---|---|
| Researcher agent | Microsoft 365 Copilot | Multi-source research synthesis |
| Analyst agent | Microsoft 365 Copilot | Data/numeric analysis — not research synthesis |
| Copilot Chat (web/mobile) | Microsoft 365 Copilot | Lighter-weight interface vs. full Copilot experience |
| Copilot Studio | Agent building | For building a custom agent, not just using one |
| Build vs. buy vs. extend | Copilot extensibility framework | Evaluate extending Copilot before a full custom build |
| Azure Vision in Foundry Tools | Foundry Tools | Visual/image content analysis |
| Azure AI Search | Foundry Tools | Retrieval and search over content — not image analysis |
| Integrated Microsoft AI solution | M365 Copilot + Foundry Tools | Shared governance = risk mitigation and safety benefits vs. an ungoverned patchwork |
3. Implementation & Adoption Strategy (20-25%)
| Concept | Feature / Area | Quick note |
|---|---|---|
| AI council | Governance structure | Cross-functional strategy, oversight, and alignment |
| Responsible AI standards | Fairness, reliability, safety, privacy, security, inclusiveness, transparency, accountability | All eight principles, not just "be ethical" |
| Adoption team | Org structure | Owns rollout, distinct from the AI council's governance role |
| Champions program | Adoption tactic | Peer-driven advocacy inside business units |
| Common adoption barriers | Change management | Identify before rollout, not after resistance appears |
Build vs. Buy vs. Extend: Quick Decision
This framework applies across multiple Domain 1 and Domain 2 questions:
| Scenario | Use this |
|---|---|
| A pre-built agent or connector already covers the need | Buy — adopt the existing Agent Store agent or Copilot connector |
| Copilot almost fits, but needs a connection to your own data or system | Extend — use the Copilot extensibility framework or Copilot Studio |
| No Microsoft or partner option covers a highly specific, differentiated need | Build — custom development, reserved for genuine gaps |
Copilot & Foundry Tools Licensing Models
| Model | Best fit | Quick note |
|---|---|---|
| Copilot pay-as-you-go | Light or occasional users | Avoids overpaying for infrequent use |
| Copilot monthly license | Regular but not daily users | Predictable recurring cost per seat |
| Copilot included with M365 subscription | Users already on a qualifying M365 plan | No separate Copilot line item for that seat |
| Foundry Tools pay-as-you-go | Variable, unpredictable workloads | Cost scales directly with usage |
| Foundry Tools commitment tiers | Steady, predictable workloads | Lower unit cost in exchange for a committed volume |
Common Mistake: Picking a Licensing Model by Habit, Not Usage Pattern
A frequent misstep — both on the exam and in real budget conversations — is defaulting to the monthly Copilot license for every user because it's the "standard" option. The licensing table above draws a sharper line: pay-as-you-go fits light or occasional users where a flat monthly fee would go mostly unused, while a monthly license makes sense for regular-but-not-daily users who need predictable per-seat cost. The same logic applies on the Foundry Tools side — commitment tiers only pay off against steady, predictable workloads, and pay-as-you-go is the safer default when usage is variable. Getting this backward is a common reason organizations either overpay for idle licenses or get surprised by variable consumption billing.
What Candidates Ask About AB-731
How is this cheat sheet different from the AB-731 study guide?
The study guide walks through a week-by-week plan and explains each domain in narrative form. This page is tables only, for a final scan right before the exam.
Is AB-731 the same as AB-730?
No. AB-730 tests hands-on daily use of Copilot. AB-731 tests business strategy and decision-making around AI adoption — no hands-on configuration is tested.
What's the fastest way to review right before the exam?
Scan the three domain tables plus the build-vs-buy-vs-extend table — that framework applies across multiple Domain 1 and Domain 2 questions.
Can I print this AB-731 cheat sheet?
Yes — every table here is plain HTML, so a browser print or "print to PDF" renders cleanly.
MSCertQuiz sells practice-exam access for AB-731 and other Microsoft certifications; this cheat sheet is written by the same team that builds those questions.
