Responsible AI β the six principles
| Keyword in Scenario | β Principle |
|---|---|
| Bias, discrimination, demographic groups | Fairness |
| Accuracy, edge cases, error handling | Reliability & Safety |
| Data handling, encryption, compliance | Privacy & Security |
| Explainability, citations, βam I talking to AI?β | Transparency |
| Accessibility, multiple languages, diverse users | Inclusiveness |
| Governance, oversight, impact assessment | Accountability |
AI model selection
| Scenario | β Model Choice |
|---|---|
| Complex reasoning, multimodal | GPT-4o |
| Simple classification, cost-sensitive | Phi-4-mini (SLM) |
| Image generation | GPT-image-1.5 |
| Document search / RAG | Embedding model |
| Speech tasks | Azure AI Speech |
Configuration parameters
| Parameter | Low Value β | High Value β |
|---|---|---|
| Temperature | Deterministic, consistent | Creative, varied |
| Top-p | Focused word choices | Diverse word choices |
| Max tokens | Short responses | Long responses |
AI workload types
| Workload | Key Differentiator |
|---|---|
| Generative | Creates NEW content |
| Agentic | Takes ACTIONS (not just creates) |
| Text analysis | UNDERSTANDS existing text |
| Speech | Converts BETWEEN spoken and written |
| Vision | ANALYSES existing images |
| Extraction | Pulls STRUCTURED DATA from unstructured sources |

Foundry ecosystem
| Component | What It Is |
|---|---|
| Foundry resource | Top-level Azure resource for AI |
| Project | Workspace within Foundry (models, agents, keys) |
| Playground | Interactive testing β no code needed |
| Foundry Tools | Dedicated AI services (Language, Speech, Vision, Content Understanding) |
| Model catalog | Browse and deploy models from multiple providers |
API patterns
| Pattern | When to Use |
|---|---|
| Chat Completions | Simple Q&A, summarisation, text tasks |
| Responses API (Agents) | Multi-step tasks, tool use, autonomous actions |
| Azure AI Language | High-volume text analysis with structured output |
| Azure AI Speech | Dedicated speech-to-text and text-to-speech |
| Azure AI Vision | High-volume image analysis |
| Content Understanding | Document, image, audio, video extraction |
Common exam traps
Top 10 exam traps
- Generative vs Agentic: If the AI is taking actions (booking, emailing), itβs agentic β not just generative
- OCR vs Content Understanding: OCR reads text; Content Understanding extracts structured fields
- Temperature 0 β accurate: It means deterministic (same input β same output), not necessarily correct
- System prompt vs user prompt: System = developer sets rules; User = end user asks questions
- Models are stateless: Full conversation history must be sent with each API call (chat completions)
- Foundry β Azure OpenAI only: Foundry includes ALL Azure AI services, not just OpenAI models
- SLM vs LLM: If the question mentions βcost-effectiveβ or βedgeβ β think small model
- Pre-built vs custom models: Use pre-built for standard documents; custom for your specific formats
- Content filters are ON by default: You configure them, not enable them
- Human-in-the-loop: Low confidence = human review, not automatic rejection
Exam day strategy
| Strategy | Why |
|---|---|
| Read the full question | Key words often appear at the end |
| Eliminate wrong answers first | Usually 2 options are clearly wrong |
| Watch for βBESTβ vs βpossibleβ | Multiple answers may work; pick the BEST one |
| Scenario keywords β service | Map keywords to the right service/workload |
| Flag and return | Donβt get stuck β flag difficult questions and come back |
| Time management | 45 min Γ· 50 questions β 54 seconds each β keep moving |

Final Knowledge Check
A hospital deploys an AI model for preliminary skin lesion analysis. The model classifies images as 'benign' or 'refer to specialist.' After deployment, they discover it's less accurate for darker skin tones. Which TWO responsible AI principles are most relevant?
An e-commerce company needs to: 1) Process 100,000 product reviews for sentiment, 2) Generate personalised response emails, 3) Create product images for new listings. Which combination of services is most appropriate?
Priya builds a chat app. After 30 messages, the app crashes with a 'context length exceeded' error. What's the most likely cause and fix?
