Microsoft Updated AI-900 Exam Questions and Answers by emelia

The correct answers are B. Implement a process of AI model validation as part of the software review process and C. Establish a risk governance committee that includes members of the legal team, members of the risk management team, and a privacy officer.

According to the Microsoft Azure AI Fundamentals (AI-900) Official Study Guide and the Microsoft Responsible AI principles, responsible AI emphasizes six key principles: fairness, reliability and safety, privacy and security, inclusiveness, transparency, and accountability. These principles ensure that AI systems are trustworthy, ethical, and safe for users and society.

Option B aligns with the reliability and safety principle. Model validation ensures that AI models behave as expected, perform accurately across different data conditions, and produce consistent results. Microsoft teaches that AI models should be validated, tested, and monitored regularly to avoid unintended outcomes, bias, or failures. Validation processes help ensure that the AI behaves responsibly before deployment and continues to perform reliably over time.

Option C aligns with the accountability and governance principle. Establishing a risk governance committee that includes legal, privacy, and risk management experts ensures that AI development and deployment are overseen responsibly. This committee is responsible for reviewing compliance with data protection laws, ensuring ethical practices, and managing risks associated with AI-driven decisions. Microsoft emphasizes that accountability requires human oversight and governance structures to ensure ethical alignment throughout the AI system’s lifecycle.

The incorrect options are:

A. Implement an Agile software development methodology: Agile is a software project management approach, not a Responsible AI principle.

D. Prevent the disclosure of the use of AI-based algorithms: This violates the transparency principle, which requires organizations to disclose when and how AI is used.

Therefore, following the official Responsible AI framework taught in AI-900, the correct and verified answers are B and C, as they directly promote reliability, safety, accountability, and governance in AI systems.

According to the Microsoft Azure AI Fundamentals (AI-900) curriculum and Microsoft Learn’s modules on Computer Vision, object detection is the AI technique used to identify and locate multiple objects within an image. Unlike simple image classification, which only labels an entire image with a single category (for example, “This is a product”), object detection not only identifies the type of object but also pinpoints its exact position by providing bounding boxes and coordinates within the image.

In the scenario described — identifying the location of products on a conveyor belt — the system must be able to detect multiple items simultaneously and determine their spatial positions. Object detection algorithms (such as YOLO, Faster R-CNN, or SSD) are specifically designed for this purpose. This allows automation systems, like robotic arms or quality inspection systems, to track product locations in real time for sorting, packaging, or defect detection.

Let’s evaluate the other options:

Image classification only determines what is in the image, not where it is located. It cannot handle multiple objects or their positions.

Image processing involves operations like resizing, filtering, or adjusting contrast, not understanding object placement.

Optical character recognition (OCR) extracts text from images and documents, unrelated to locating physical items.

Thus, per Microsoft Learn’s AI-900 guidance, object detection is the correct computer vision capability when a task requires both identification and spatial localization of items in an image or video stream.

✅ Final Answer: Object detection

For an app that helps employees write emails and reports based on user prompts, you need a text generation model capable of understanding natural language instructions and producing coherent, contextually appropriate output. Azure OpenAI GPT models—available through Azure AI Foundry (formerly Azure OpenAI Studio)—are specifically designed for such generative tasks.

By integrating GPT-3.5 or GPT-4, the app can analyze prompts like “Write a professional email to a client about project updates” and automatically generate polished text in seconds.

The other options do not fit:

A. Azure AI Speech: Converts spoken language to text or text to speech; not suitable for generating written content.

C. Azure AI Vision: Processes and analyzes images or video content.

D. Azure Machine Learning Studio: Used for training, testing, and deploying custom ML models, not directly for content generation.

Therefore, to create a writing-assistance app for emails and reports, the correct solution is B. Azure OpenAI in Foundry Models using GPT-based language generation.

According to the Microsoft Learn documentation and the Azure AI Fundamentals (AI-900) study guide, the GPT (Generative Pre-trained Transformer) family of models within Azure OpenAI Service is used for text-based natural language tasks, including summarization, content generation, and text completion.

When you need to summarize text from a document, GPT models (such as GPT-3.5 or GPT-4) can process large sections of text, extract the most relevant details, and generate concise summaries that retain the key meaning. The summarization task uses the model’s natural language understanding capabilities to identify core concepts and generate human-like, coherent text.

Other options are incorrect:

A. Whisper → Used for speech-to-text transcription, not text summarization.

B. DALL-E → Generates images from text prompts, not text summaries.

C. Codex → Specializes in code generation and completion, not document summarization.
