AB-100 is an expert-level architecture exam about turning business requirements into secure, governed agentic AI solutions across Microsoft 365, Dynamics 365, Power Platform, Copilot Studio, and Microsoft Foundry. Microsoft's published October 2026 outline weights planning at 25-30%, design at 25-30%, and deployment at 40-45%.
Microsoft allows 100 minutes and requires a scaled score of 700 or greater, but does not publish a fixed question count. Pricing depends on the country where the exam is proctored. An eligible Associate certification is required to earn the Agentic AI Business Solutions Architect Expert credential; Microsoft does not state that it must be held before sitting AB-100.
Use these 700 practice questions to test architecture decisions, not product-name recall. Give extra attention to the 40-45% deployment domain: evaluation and telemetry, testing, application lifecycle management, responsible AI, security, grounding-data access, auditability, prompt-attack defenses, and measurable business outcomes.
AB-100 assesses architecture of secure, scalable, integrated AI-powered business solutions across Microsoft 365, Dynamics 365, Power Platform, Copilot Studio, and Microsoft Foundry. The published October 2026 outline consolidates the exam into planning, design, and deployment, with deployment carrying the largest weighting.
Microsoft describes an accomplished solution architect who can translate business and technical requirements into agentic-first architectures, design multi-agent orchestration, choose build-versus-buy approaches, lead delivery, and connect technical decisions to governance, cost, adoption, and measurable outcomes.
There is no published prerequisite to sit the AB-100 exam. To earn the Agentic AI Business Solutions Architect Expert certification, however, Microsoft requires both AB-100 and at least one eligible Associate-level certification listed on the certification page.
The proctored exam allows 100 minutes, may contain interactive components, and requires a scaled score of 700. Microsoft does not publish a fixed question count. Pricing varies by the country or region where the exam is proctored, and the English exam is scheduled for an October 2026 update.
AB-100 is part of an Expert credential for architects leading Microsoft agentic AI programmes. It signals breadth across business applications, AI platforms, solution governance, and delivery, especially when combined with the required Associate credential and real implementation evidence.
5 sample questions with answers and explanations. The full bank has 700 questions, enough for 14 full-length practice exams.
Preview — answers shown1. Contoso Manufacturing is planning their Cloud Adoption Framework journey for AI. They have completed the Strategy phase and identified key AI use cases. According to the Microsoft Cloud Adoption Framework for Azure, what is the correct sequence of phases they should follow after Strategy? (Select one!)
Explanation
The Cloud Adoption Framework follows a structured sequence: Strategy, Plan, Ready, Adopt, Govern, and Manage. After completing Strategy, the next step is Plan, which involves creating a detailed adoption plan including digital estate assessment and skills readiness. Ready prepares the Azure landing zone and environment. Adopt covers migration and innovation activities. Govern establishes governance policies and compliance. Manage focuses on ongoing operations management. Starting with Ready before Plan skips critical planning activities. Starting with Adopt before infrastructure readiness creates implementation risks. Inserting Govern before Ready prevents proper environment preparation.
2. Tailspin Financial is implementing the Cloud Adoption Framework's AI adoption process for their enterprise AI initiative. The leadership team has completed the Strategy phase and identified AI opportunities. What is the correct sequence of the remaining phases they must follow? (Select one!)
Explanation
The Cloud Adoption Framework for Azure follows the sequence: Strategy, Plan, Ready, Adopt, Govern, Manage. After completing the Strategy phase, the organization must Plan (define the implementation roadmap and assess skills), Ready (prepare the cloud environment and landing zones), Adopt (implement and migrate workloads), Govern (establish policies and compliance frameworks), and Manage (operationalize and continuously optimize). Skipping ahead to Adopt before planning and readiness leads to failed implementations. Governing before adoption means creating policies without understanding actual workload patterns. Each phase builds on the outputs of the previous one.
3. Adatum Corp is using the Cloud Adoption Framework (CAF) for AI to guide their enterprise AI adoption. They have already defined their AI use cases, selected Microsoft AI technologies, and developed a responsible AI strategy. According to the CAF AI adoption process, which phase should they focus on next to build their Azure AI environment, establish networking, and choose an appropriate architecture? (Select one!)
Explanation
The AI Ready phase of the Cloud Adoption Framework for AI focuses on building the AI environment, establishing AI networking and reliability, setting up an Azure landing zone foundation, choosing an appropriate architecture, and using AI design areas. The tasks described — defining use cases, selecting AI technologies, and developing a responsible AI strategy — correspond to the AI Strategy and AI Plan phases. After completing those foundational steps, the next phase is AI Ready, which prepares the technical environment for AI workloads. Govern AI focuses on assessing organizational risks and enforcing governance policies. Manage AI addresses ongoing operations including model management, cost management, and business continuity. The CAF AI adoption process follows a structured sequence: AI Strategy, AI Plan, AI Ready, Govern AI, Secure AI, and Manage AI.
4. Fabrikam Global is implementing the Cloud Adoption Framework for AI to guide their enterprise AI strategy. The leadership team wants to understand the correct sequence of phases. What is the correct order of the Cloud Adoption Framework phases for AI adoption? (Select one!)
Explanation
The Cloud Adoption Framework for Azure follows a specific sequence: Strategy (define business justification and expected outcomes), Plan (align actionable adoption plans to business outcomes), Ready (prepare the cloud environment), Adopt (implement the planned changes), Govern (establish governance methodologies), and Manage (operations management for cloud and hybrid solutions). Starting with Strategy before Plan ensures that business objectives drive the technical planning. The Ready phase prepares infrastructure before Adopt implements solutions. Govern and Manage provide ongoing oversight after adoption.
5. Northwind Healthcare needs to monitor the effectiveness of their deployed Copilot Studio agents. The operations team wants to establish a comprehensive monitoring strategy. Which metric is MOST indicative of overall agent effectiveness? (Select one!)
Explanation
Resolution rate measures the percentage of conversations resolved without human escalation, directly indicating whether the agent successfully handles user needs. Combined with customer sentiment scores, these metrics provide a holistic view of both effectiveness and quality. The total number of conversations initiated measures volume but not quality or outcomes. Copilot Credits consumption is a cost metric that reflects usage intensity rather than effectiveness. The number of topics and actions reflects agent complexity but has no correlation with whether the agent actually resolves user issues satisfactorily.
The published October 2026 outline assigns 25-30% to planning, 25-30% to design, and 40-45% to deployment of AI-powered business solutions.
Microsoft allows 100 minutes. The exam may include interactive components in addition to standard question formats.
A scaled score of 700 or greater passes. Microsoft does not equate 700 with a fixed percentage correct.
Microsoft does not publish a fixed question count, so candidates should not rely on third-party claims of an exact total.
Microsoft requires an eligible Associate credential to earn the Expert certification in addition to passing AB-100, but does not state that it must be earned before sitting the exam.
The role spans Microsoft 365, Dynamics 365, Power Platform, Copilot Studio, Microsoft Foundry, agent protocols, security, governance, testing, telemetry, and ALM.
