Pass the Microsoft Microsoft Certified: Azure AI Fundamentals AI-900 Questions and answers with CertsForce

According to the Microsoft Azure AI Fundamentals (AI-900) official study guide and Microsoft Learn module “Extract insights from text with the Text Analytics service”, key phrase extraction is a feature of the Text Analytics service that identifies the most important words or phrases in a given document. It helps summarize the main ideas by isolating significant concepts or terms that describe what the text is about.

In this scenario, the goal is to determine which documents share similar topics or themes. By extracting key phrases from each document (for example, “policy renewal,” “coverage limits,” “claim process”), you can compare and categorize documents based on overlapping keywords. This is exactly how key phrase extraction is used—to summarize and group text content by topic relevance.

The other options do not fit this use case:

A. Translation uses the Translator service, not key phrase extraction.

B. Generating video captions involves speech recognition and computer vision.

C. Identifying sentiment relates to sentiment analysis, not key phrase extraction.

Before running a pipeline in Azure Machine Learning Designer, you must have an available compute resource (such as a compute instance or compute cluster). Compute provides the processing power required to train, evaluate, and execute the pipeline’s modules.

Other options:

A. Jupyter notebook – Used for code-first development, not required for Designer pipelines.

B. Registered model – Created after running a pipeline, not before.

The Azure AI Document Intelligence service (formerly Form Recognizer) is designed to analyze, extract, and structure data from scanned or digital documents such as invoices, receipts, contracts, and forms. According to the Microsoft Learn module “Extract data from documents with Azure AI Document Intelligence”, the service uses optical character recognition (OCR) and pretrained machine learning models to automatically extract key information.

A. Extract the invoice number from an invoice – YESThe prebuilt invoice model in Document Intelligence can detect and extract key fields such as invoice number, date, total amount, tax, and vendor details from scanned or digital invoices.

B. Identify the retailer from a receipt – YESThe prebuilt receipt model can recognize fields like merchant name (retailer), transaction date, total spent, and tax amount, making this option correct as well.

C. Find images of products in a catalog – NOThis is a computer vision or Custom Vision use case, not a document data extraction task.

D. Translate a form from French to English – NOTranslation involves Azure AI Translator, part of the Language service, not Document Intelligence.

Hence, the correct and Microsoft-verified answers are:

✅ A. Extract the invoice number from an invoice

✅ B. Identify the retailer from a receipt

<  A webchat bot can interact with users visiting a website → Yes

 Automatically generating captions for pre-recorded videos is an example of conversational AI → No

 A smart device in the home that responds to questions such as “What will the weather be like today?” is an example of conversational AI → Yes

\ These answers are based on the Microsoft Azure AI Fundamentals (AI-900) Official Study Guide and the Microsoft Learn module “Explore conversational AI in Microsoft Azure.”

1. A webchat bot can interact with users visiting a website → Yes

This statement is true. A webchat bot is a key example of conversational AI, which allows users to communicate with an intelligent system through natural language. The Azure Bot Service supports a webchat channel, enabling website visitors to ask questions or get assistance directly through a chat interface embedded on a webpage. This allows businesses to provide 24/7 automated support and interactive engagement without human intervention.

2. Automatically generating captions for pre-recorded videos is an example of conversational AI → No

This is incorrect because automatically generating captions involves speech-to-text transcription, which falls under speech recognition and not conversational AI. While it uses AI to convert audio into text, it does not involve interactive communication or natural language dialogue. This task would be handled by Azure AI’s Speech service, not the conversational AI framework.

3. A smart device in the home that responds to questions such as “What will the weather be like today?” is an example of conversational AI → Yes

This is true. Smart assistants like those found in home devices (e.g., voice-activated systems) use conversational AI technologies to process spoken language (using natural language processing and speech recognition) and generate appropriate responses. This interaction represents a classic example of conversational AI, as it allows human-like dialogue between a user and an AI system.

✅ Final Answers:

Webchat bot interacting with users → Yes

Auto-captioning videos → No

Smart home device answering questions → Yes

The correct mappings are based on the Microsoft Azure AI Fundamentals (AI-900) curriculum topic: “Describe features of computer vision workloads.” Microsoft divides computer vision tasks into key workload types — image classification, object detection, facial recognition, and optical character recognition (OCR) — each designed for specific visual analysis objectives.

Identify celebrities in images → Facial recognitionFacial recognition goes beyond simple face detection; it can identify or verify specific individuals by comparing facial features with known profiles. According to Microsoft Learn, the Face service in Azure Cognitive Services can detect, recognize, and identify people in photos or videos. Recognizing celebrities or known individuals is a prime example of facial recognition.

Extract movie title names from movie poster images → Optical Character Recognition (OCR)OCR is used to detect and extract text content from images, such as printed or handwritten words. Azure’s Computer Vision API uses OCR technology to read text in various languages from photos, scanned documents, or posters. Therefore, extracting movie titles or actor names from a poster image is a perfect use case for OCR.

Locate vehicles in images → Object detectionObject detection identifies and locates specific objects within an image, returning bounding boxes that indicate their positions. In Azure, the Custom Vision service or Computer Vision object detection models are used to detect multiple objects like vehicles, pedestrians, or animals in a single image.

Summary:

Facial recognition → Identifies specific people (celebrities)

OCR → Extracts text (movie titles)

Object detection → Finds and locates physical items (vehicles)

Thus, the verified and official answer is:

Full Detailed Explanation (250–300 words):

The correct answer is A. AI systems should treat people fairly.

This statement aligns with one of Microsoft’s six Responsible AI principles, which are:

Fairness – AI systems should treat all people fairly and avoid bias.

Reliability and Safety

Privacy and Security

Inclusiveness

Transparency

Accountability

The principle of Fairness ensures that AI models do not discriminate based on factors such as race, gender, age, or socioeconomic background. For example, a loan approval or hiring model must provide equal opportunity to all qualified applicants regardless of demographic differences.

B (Not revealing design details) contradicts Transparency, which promotes openness about AI functionality.

C (Black-box models) goes against Microsoft’s push for Explainable AI.

D (Protect developers’ interests) is not part of Microsoft’s Responsible AI framework.

Therefore, the verified correct answer is A. AI systems should treat people fairly.

In Azure Machine Learning designer, a low-code drag-and-drop interface, users can visually build machine learning workflows. According to the AI-900 study guide and Microsoft Learn module “Create and publish models with Azure Machine Learning designer”, two key components that can be dragged onto the designer canvas are datasets and modules.

Datasets (A): These are collections of data that serve as the input for training or evaluating models. They can be registered in the workspace and then dragged onto the canvas for use in transformations or model training.

Modules (D): These are prebuilt processing and modeling components that perform operations such as data cleaning, feature engineering, model training, and evaluation. Examples include “Split Data,” “Train Model,” and “Evaluate Model.”

Compute (B) and Pipeline (C) are not drag-and-drop items within the designer. Compute targets are infrastructure resources used to run the pipeline, while a pipeline represents the overall workflow, not a component that can be added like a dataset or module.

Hence, the correct answers are A. Dataset and D. Module.

Statement

Yes / No

Providing an explanation of the outcome of a credit loan application is an example of the Microsoft transparency principle for responsible AI.

Yes

A triage bot that prioritizes insurance claims based on injuries is an example of the Microsoft reliability and safety principle for responsible AI.

Yes

An AI solution that is offered at different prices for different sales territories is an example of the Microsoft inclusiveness principle for responsible AI.

No

This question is based on the Responsible AI principles defined by Microsoft, which are part of the AI-900 Microsoft Azure AI Fundamentals curriculum. Microsoft’s Responsible AI framework consists of six key principles: Fairness, Reliability and Safety, Privacy and Security, Inclusiveness, Transparency, and Accountability. Each principle ensures that AI systems are developed and used in a way that benefits people and society responsibly.

Transparency Principle – YesProviding an explanation for a loan decision aligns with the Transparency principle. Microsoft defines transparency as helping users and stakeholders understand how AI systems make decisions. For example, when a credit scoring AI model approves or denies a loan, explaining the factors that influenced that outcome (such as credit history or income level) ensures that customers understand the reasoning process. This builds trust and supports responsible deployment.

Reliability and Safety Principle – YesA triage bot that prioritizes insurance claims based on injury severity relates directly to Reliability and Safety. This principle ensures AI systems operate consistently, perform accurately, and produce dependable outcomes. In the case of the triage bot, it must reliably assess the input data (injury descriptions) and rank claims appropriately to avoid harm or misjudgment, aligning with Microsoft’s emphasis on designing AI systems that are safe and robust.

Inclusiveness Principle – NoAn AI solution priced differently across sales territories is not related to Inclusiveness. Inclusiveness focuses on ensuring accessibility and eliminating bias or exclusion for all users—especially those with disabilities or underrepresented groups. Pricing strategy is a business decision, not an inclusiveness issue. Therefore, this statement is No.

In summary, based on the AI-900 Responsible AI principles, the correct selections are:

According to the Microsoft Azure AI Fundamentals (AI-900) official study guide and Microsoft Learn module “Identify features of common machine learning types”, regression is a supervised machine learning technique used to predict continuous numerical values based on one or more input features. In this scenario, the task is to predict a vehicle’s miles per gallon (MPG)—a continuous numeric value—based on several measurable factors such as weight, engine power, and other specifications.

Regression models learn the mathematical relationship between input variables (independent features) and a numeric target variable (dependent outcome). Common regression algorithms include linear regression, decision tree regression, and support vector regression. In the example, the model would analyze historical data of vehicles and learn patterns that map characteristics (like engine size, horsepower, and weight) to fuel efficiency. Once trained, it can predict the MPG for a new vehicle configuration.

The other options describe different problem types:

Classification predicts discrete categories (for example, whether a car is “fuel efficient” or “not fuel efficient”), not continuous values.

Clustering is an unsupervised learning method that groups data points based on similarities without predefined labels, not predictive modeling.

Anomaly detection identifies data points that significantly deviate from normal patterns, such as detecting engine sensor failures or fraudulent transactions.

Since predicting MPG involves estimating a numeric value within a continuous range, regression is the most appropriate model type.

In summary, per AI-900 training content, regression models are used when the output variable is numeric, classification for categorical outputs, and clustering for pattern discovery. Therefore, predicting miles per gallon based on vehicle features is a textbook example of a regression problem in Azure Machine Learning.

As described in the AI-900 study guide under “Identify features of machine learning,” regression is a supervised learning technique used to predict continuous numerical values. In this scenario, the goal is to predict energy output (a continuous variable) based on density (a numeric input).

Regression models find relationships between variables by fitting a line or curve that best represents the trend of the data. In Azure Machine Learning, regression algorithms such as linear regression, decision tree regression, and boosted decision trees are commonly used for such predictions.

Classification (A) predicts discrete labels (e.g., “High” or “Low”), not numeric values.

Clustering (B) groups similar data points but does not perform prediction.

Knowledge mining (C) extracts insights from unstructured data using tools like Azure AI Search and Cognitive Skills.

Hence, based on AI-900 fundamentals, predicting energy based on density requires a regression workload.
