Intermediate-Level
1. What is Azure AI?
Answer: Azure AI is a collection of Microsoft cloud services and tools that enable organizations to build, deploy and manage artificial intelligence solutions. It includes capabilities for machine learning, computer vision, speech, language processing, generative AI and intelligent agents.
2. What is machine learning?
Answer: Machine learning is an AI approach where systems learn patterns from data and use those patterns to make predictions or decisions without being explicitly programmed for every scenario.
3. What is supervised learning?
Answer: Supervised learning trains a model using labeled data. Each training example contains input data and a known target value. Common applications include classification and regression.
4. What is classification in machine learning?
Answer: Classification predicts a category or class. For example, an email classification model can determine whether a message is spam or legitimate.
5. What is regression?
Answer: Regression predicts a numerical value based on input features. For example, a regression model could estimate house prices based on location, size and other characteristics.
6. What is computer vision?
Answer: Computer vision enables applications to interpret and analyze visual information such as images and videos. Typical capabilities include image analysis, object detection, image classification and optical character recognition.
7. What is OCR?
Answer: Optical Character Recognition, or OCR, extracts readable text from images or scanned documents. It is useful for processing invoices, forms, receipts and other document-based information.
8. What is natural language processing?
Answer: Natural language processing, or NLP, enables computers to understand, analyze and generate human language. Applications include sentiment analysis, translation, summarization, question answering and conversational AI.
9. What is generative AI?
Answer: Generative AI creates new content based on patterns learned from data. It can generate text, images, code and other content. Large language models are commonly used for text-based generative AI applications.
10. What is responsible AI?
Answer: Responsible AI involves developing and using AI systems in ways that promote fairness, reliability, safety, privacy, security, inclusiveness and transparency while reducing potential risks and unintended impacts.
11. What is Azure Machine Learning?
Answer: Azure Machine Learning is a cloud platform for developing, training, deploying and managing machine learning models. It supports data scientists and developers throughout the machine learning lifecycle.
12. What is a training dataset?
Answer: A training dataset contains examples used by a machine learning algorithm to learn relationships and patterns. The quality and relevance of the training data directly influence model performance.
13. What is a validation dataset?
Answer: A validation dataset is used during model development to evaluate performance and help tune model parameters without using the final test dataset.
14. What is a test dataset?
Answer: A test dataset is used to evaluate how well a trained model performs on previously unseen data. It provides an estimate of how the model may perform in real-world scenarios.
15. Why is data quality important in AI?
Answer: High-quality data helps models learn accurate and meaningful patterns. Incomplete, inconsistent, biased or incorrect data can reduce model performance and potentially produce unreliable predictions.
Advanced-Level
1. How would you select an Azure AI service for a business requirement?
Answer: First identify the AI workload, such as prediction, image analysis, speech, language processing or generative AI. Then evaluate the required capabilities, data requirements, scalability, security, integration needs and cost before selecting the most appropriate Azure service.
2. What is overfitting in machine learning?
Answer: Overfitting occurs when a model learns the training data too closely, including noise and irrelevant patterns. Consequently, it may perform very well on training data but poorly on new, unseen data.
3. How can overfitting be reduced?
Answer: Techniques include using more representative training data, simplifying the model, regularization, cross-validation, early stopping and appropriate feature selection. The correct approach depends on the model and dataset.
4. What is underfitting?
Answer: Underfitting occurs when a model is too simple to capture important patterns in the training data. It generally results in poor performance on both training and unseen datasets.
5. What is the difference between precision and recall?
Answer: Precision measures how many predicted positive results are actually positive. Recall measures how many actual positive cases the model successfully identifies. The appropriate balance depends on the business scenario.
6. What is a confusion matrix?
Answer: A confusion matrix summarizes classification results using true positives, true negatives, false positives and false negatives. It helps evaluate classification performance and derive metrics such as precision, recall and accuracy.
7. What is Azure AI Foundry used for?
Answer: Azure AI Foundry provides capabilities for developing, evaluating and managing AI applications and agents. It helps teams work with models, tools, evaluation workflows and AI application development in a structured environment.
8. What is prompt engineering?
Answer: Prompt engineering involves designing effective instructions for generative AI models. Well-structured prompts can provide context, define expected output and establish constraints, improving the relevance and consistency of model responses.
9. What is grounding in generative AI?
Answer: Grounding connects a generative AI model's responses to reliable external information or organizational data. This can help improve factual relevance and reduce responses that are unsupported by the available source information.
10. What is Retrieval-Augmented Generation (RAG)?
Answer: RAG combines information retrieval with generative AI. Relevant information is retrieved from a knowledge source and provided to the language model as context, allowing it to generate responses based on current or domain-specific information.
11. How can responsible AI be applied to a generative AI solution?
Answer: Organizations should evaluate risks such as harmful content, bias, privacy concerns, inaccurate responses and inappropriate use. They can implement safeguards, content filtering, monitoring, human oversight and evaluation processes.
12. What is model evaluation?
Answer: Model evaluation measures how effectively an AI model performs against defined objectives. Depending on the workload, evaluation can involve metrics such as accuracy, precision, recall, F1 score, latency, relevance or response quality.
13. What factors should be considered before deploying an AI model?
Answer: Important factors include accuracy, scalability, latency, security, privacy, cost, monitoring, reliability, responsible AI requirements and integration with existing applications and data systems.
14. What is the difference between traditional machine learning and generative AI?
Answer: Traditional machine learning often focuses on predicting values or classifications from existing data. Generative AI focuses on producing new content, such as text, code, images or other outputs, based on learned patterns.
15. How would you explain the business value of Azure AI to a non-technical stakeholder?
Answer: Azure AI can automate repetitive tasks, extract insights from data, improve customer experiences and support faster decision-making. The business value should be explained in terms of measurable outcomes such as productivity, efficiency, customer satisfaction and reduced operational effort.
