The training emphasizes practical development, responsible AI, security, evaluation, and production readiness. It is particularly valuable for developers who want to create AI-powered applications and agentic solutions that can reason, retrieve information, interact with tools, and automate complex business workflows.
Intermediate-Level
1. What is Azure AI?
Answer:
Azure AI is Microsoft's cloud-based portfolio of artificial intelligence services and tools. It enables developers to build applications using capabilities such as generative AI, language processing, speech, computer vision, machine learning, and AI agents without having to build every AI capability from scratch.
2. What is an AI agent?
Answer:
An AI agent is a software system that can interpret a user's objective, reason about the required steps, use available tools or data sources, and take actions to accomplish a task. Unlike a basic chatbot, an agent can dynamically decide which actions or tools are needed.
3. What is the role of Azure AI Foundry in AI application development?
Answer:
Azure AI Foundry provides an environment for developing and managing AI applications and agents. It brings together models, tools, evaluations, tracing, and deployment capabilities to help developers move AI solutions from experimentation toward production.
4. What is generative AI?
Answer:
Generative AI refers to AI systems capable of generating new content based on learned patterns. Depending on the model, generated content can include text, code, images, summaries, or structured responses.
5. What is prompt engineering?
Answer:
Prompt engineering is the process of designing instructions that guide an AI model toward useful and consistent responses. Effective prompts typically provide context, define the desired task, specify constraints, and describe the expected output format.
6. What is Retrieval-Augmented Generation (RAG)?
Answer:
RAG combines information retrieval with generative AI. Instead of relying only on information encoded in a model, the application retrieves relevant information from external sources and provides that information as context to the model before generating a response.
7. Why is RAG useful in enterprise applications?
Answer:
RAG can help AI applications answer questions using organization-specific and current information. It can reduce dependence on model training for every data update and can improve the relevance and traceability of responses.
8. What is a grounding source?
Answer:
A grounding source provides external information that an AI model can use when generating a response. Examples include documents, databases, websites, enterprise knowledge bases, and search indexes.
9. What are tools in an AI agent?
Answer:
Tools are functions or services that allow an agent to perform actions beyond generating text. Examples include calling APIs, querying databases, searching knowledge sources, retrieving records, or triggering business processes.
10. What is function calling?
Answer:
Function calling allows an AI model to identify when an application-defined function should be executed. The model typically produces structured arguments, while the application executes the function and returns the result to the model.
11. How does an AI agent differ from a traditional chatbot?
Answer:
A traditional chatbot generally follows predefined conversational logic or simply generates responses. An AI agent can reason about a goal, select tools, access information, perform actions, and potentially complete multi-step workflows.
12. What is responsible AI?
Answer:
Responsible AI involves developing and operating AI systems in ways that promote safety, fairness, reliability, transparency, privacy, accountability, and appropriate human oversight.
13. Why is evaluation important for generative AI applications?
Answer:
AI outputs can vary and may contain incorrect or unsafe information. Evaluation helps developers measure response quality, relevance, groundedness, safety, and other application-specific criteria before and after deployment.
14. What is a system prompt?
Answer:
A system prompt provides high-level instructions that establish the AI application's behavior, role, constraints, and response expectations. It can help maintain consistent behavior across user interactions.
15. What factors should developers consider before deploying an AI application?
Answer:
Developers should consider response quality, security, privacy, latency, cost, scalability, monitoring, evaluation, responsible AI requirements, authentication, authorization, and failure-handling mechanisms.
Advanced-Level
1. How would you design a production-ready RAG application in Azure?
Answer:
A production RAG architecture would typically include document ingestion, parsing and chunking, embedding generation, indexing, retrieval, prompt construction, model inference, response validation, monitoring, and evaluation. Security controls should protect the underlying data, while retrieval quality should be measured using representative test datasets.
2. How can you reduce hallucinations in an AI application?
Answer:
Hallucinations can be reduced by grounding responses with trusted data, improving retrieval quality, providing explicit system instructions, constraining the response format, using appropriate model settings, validating outputs, and evaluating the application against realistic test cases. Human review can also be introduced for high-impact scenarios.
3. How would you select between different Azure AI models?
Answer:
Model selection should consider the application's requirements rather than simply choosing the largest model. Developers should evaluate reasoning ability, context requirements, latency, throughput, cost, multimodal capabilities, output quality, and availability in the target Azure environment.
4. Explain the architecture of an agentic AI application.
Answer:
An agentic application generally contains an interaction layer, agent orchestration layer, model, memory or state management, knowledge sources, tools, security controls, and monitoring/evaluation components. The agent interprets the objective, determines the next action, invokes tools when necessary, processes results, and continues until the task is completed or requires human intervention.
5. How would you secure an AI agent that can call enterprise APIs?
Answer:
The agent should operate with least-privilege permissions. Authentication and authorization should be enforced independently of model-generated instructions. Sensitive credentials should be stored securely, tool inputs should be validated, API access should be scoped, and potentially destructive operations should require additional controls or human approval.
6. What is prompt injection and how can it affect an AI agent?
Answer:
Prompt injection occurs when malicious or unintended instructions manipulate an AI application's behavior. In an agentic system, this can become more serious if the model has access to tools or sensitive data. Mitigations include separating trusted instructions from untrusted content, validating tool calls, enforcing permissions outside the model, filtering inputs, and monitoring agent activity.
7. How would you implement observability for an AI application?
Answer:
Observability should cover application requests, model calls, latency, token usage, retrieval performance, tool invocations, errors, safety events, and user outcomes. Tracing individual agent steps is particularly useful for identifying whether failures originate from retrieval, reasoning, tool execution, or application logic.
8. How can an AI agent maintain context across multiple interactions?
Answer:
An application can maintain conversational state by storing relevant conversation history or structured state outside the model and selectively providing it during subsequent interactions. Long-term information should be managed carefully to avoid unnecessary context, privacy issues, and increased token consumption.
9. What is the difference between short-term conversation history and long-term memory?
Answer:
Short-term history represents the current interaction context needed to maintain a conversation. Long-term memory stores selected information that may remain useful across sessions. Long-term memory requires stronger controls around relevance, privacy, retention, and deletion.
10. How would you optimize the cost of a generative AI application?
Answer:
Cost can be controlled by selecting appropriately sized models, reducing unnecessary prompt and context tokens, improving retrieval so only relevant information is sent to the model, caching suitable results, controlling agent loops, and monitoring token consumption. Evaluation should ensure cost reductions do not significantly degrade quality.
11. How would you handle a tool failure during an agent workflow?
Answer:
The application should distinguish recoverable from unrecoverable errors. For recoverable failures, the agent may retry within defined limits or use an alternative tool. For critical failures, it should provide a controlled response rather than repeatedly attempting the action. Logging and tracing should capture the failure for investigation.
12. How can an AI application enforce structured outputs?
Answer:
Developers can define an expected schema and use structured-output capabilities where supported. Application-side validation should still verify that the returned data conforms to the required schema before it is passed to downstream systems.
13. What is the importance of human-in-the-loop design for AI agents?
Answer:
Human oversight is valuable when an agent can make consequential decisions or perform sensitive actions. The system can require approval before activities such as financial transactions, deletion of records, external communications, or other high-impact operations.
14. How would you evaluate an AI agent beyond checking whether its final answer is correct?
Answer:
Evaluation should examine the complete workflow. Metrics can include task completion, factual accuracy, groundedness, retrieval quality, tool-selection accuracy, tool-call success, safety, latency, cost, and consistency. For complex agents, evaluating intermediate steps can reveal why an otherwise incorrect result occurred.
15. How would you move an AI agent from prototype to production?
Answer:
The process should include establishing measurable requirements, creating representative evaluation datasets, hardening prompts and tool interfaces, implementing authentication and authorization, adding monitoring and tracing, testing failure scenarios, controlling costs, validating responsible-AI requirements, and conducting staged deployment. Production feedback should then be incorporated into continuous evaluation and improvement.
