Topics Covered in the Exam
Let me break down the most important domains clearly.
1. Agentic AI Architecture
This exam strongly focuses on agent-first design.
You must understand:
- Multi-agent orchestration
- Cross-platform AI solutions
- Copilot Studio agents
- Microsoft Foundry tools
- A2A and MCP protocols
- Agent lifecycle management
This is NOT about building a chatbot.
It is about designing an AI ecosystem.
2. Microsoft Copilot & Dynamics 365
You will face questions around:
- Customizing Copilot behavior
- What can and cannot be modified
- Copilot Studio analytics
- Agent extension vs configuration
- Dynamics 365 opportunity summaries
Very scenario-driven.
You must understand platform boundaries.
3. Governance & Responsible AI (Highly Tested)
This domain is critical.
You must clearly know when to use:
- Microsoft Purview
- Azure Policy
- RBAC
- Data residency controls
- Logging & audit trails
- Access restriction strategies
- Model fine-tuning governance
This exam heavily emphasizes Responsible AI architecture.
4. Security & Monitoring
Expect deep questions on:
- Azure Monitor
- Microsoft Defender
- Azure AI Content Safety
- Compliance enforcement
- Prompt injection prevention
- Grounding data protection
Security is not optional here.
It is central.
5. ALM & Deployment Strategy
Architect-level thinking required.
You need clarity on:
- Power Platform solutions
- Pipelines
- Promotion processes
- Quality gates
- Version control
- Environment strategy
This is a solution architect exam, not a developer exam.
6. Business Value & ROI
Microsoft is pushing AI that delivers business value.
You must understand:
- Resolution rate
- Deflection rate
- Accuracy metrics
- Engagement tracking
- ROI evaluation
- Measuring AI effectiveness
This exam aligns AI with enterprise outcomes.
Difficulty Level
My honest opinion:
👉 Moderate to Advanced
👉 Architect-level reasoning
👉 Less coding
👉 More design decisions
If you are already working with:
- Dynamics 365
- Power Platform
- Azure AI
- Governance frameworks
You will connect better with the scenarios.
