Ace Your AI-900 Microsoft Certified: Azure AI Fundamentals Exam

The correct answer is “adding and connecting modules on a visual canvas.”

According to the Microsoft Azure AI Fundamentals (AI-900) Official Study Guide and the Microsoft Learn module “Explore automated machine learning in Azure Machine Learning,” the Azure Machine Learning designer is a drag-and-drop, no-code environment that allows users to create, train, and deploy machine learning models visually. It is specifically designed for users who prefer an intuitive graphical interface rather than writing extensive code.

Microsoft Learn defines Azure Machine Learning designer as a tool that allows you to “build, test, and deploy machine learning models by dragging and connecting pre-built modules on a visual canvas.” These modules can represent data inputs, transformations, training algorithms, and evaluation processes. By linking them together, users can create an end-to-end machine learning pipeline.

The designer simplifies the machine learning workflow by allowing data scientists, analysts, and even non-developers to:

Import and prepare datasets visually.

Choose and connect algorithm modules (e.g., classification, regression, clustering).

Train and evaluate models interactively.

Publish inference pipelines as web services for prediction.

Let’s analyze the other options:

Automatically performing common data preparation tasks – This describes Automated ML (AutoML), not the Designer.

Automatically selecting an algorithm to build the most accurate model – Also a characteristic of AutoML, where the system tests multiple algorithms automatically.

Using a code-first notebook experience – This describes the Azure Machine Learning notebooks environment, which uses Python and SDKs, not the Designer interface.

Therefore, based on the official AI-900 learning objectives and Microsoft Learn documentation, the Azure Machine Learning designer allows you to create models by adding and connecting modules on a visual canvas, providing a no-code, interactive experience ideal for users building custom machine learning workflows visually.

The correct answers are A and D because both scenarios involve extracting structured information from documents, which is exactly what Azure Form Recognizer is designed to do.

According to the Microsoft Azure AI Fundamentals (AI-900) official study guide and Microsoft Learn module “Explore computer vision”, Form Recognizer is an Azure Cognitive Service that uses advanced Optical Character Recognition (OCR) and machine learning to extract key-value pairs, tables, and text from structured and semi-structured documents such as receipts, invoices, business cards, and forms. It allows organizations to automate data entry and digitize document processing.

A. Extract the invoice number from an invoice → CorrectForm Recognizer can identify fields such as invoice number, total amount, date, vendor name, and billing address directly from invoices. It uses prebuilt models for invoices and receipts that automatically detect and extract relevant information without requiring extensive manual labeling. As stated in Microsoft Learn, “Form Recognizer extracts information from documents like receipts and invoices and returns structured data including key-value pairs.”

D. Identify the retailer from a receipt → CorrectThe prebuilt receipt model in Form Recognizer can read printed or scanned receipts and extract data points such as retailer name, transaction date, total amount, and tax information. This makes it ideal for expense reporting, auditing, or financial reconciliation.

The following options are incorrect:

B. Translate a form from French to English → This task involves language translation, which is performed by Azure Translator, not Form Recognizer.

C. Find an image of a product in a catalog → This requires object detection or image classification, which are part of Computer Vision, not Form Recognizer.

Therefore, based on Microsoft’s AI-900 learning objectives and documentation, the two correct scenarios are:

✅ A. Extract the invoice number from an invoice

✅ D. Identify the retailer from a receipt

The correct completion of the sentence is:

“The Form Recognizer service can be used to extract information from a driver’s license to populate a database.”

According to the Microsoft Azure AI Fundamentals (AI-900) official study guide and the Microsoft Learn module “Identify features of computer vision workloads,” Azure Form Recognizer (part of Azure AI Document Intelligence) is a document processing service that uses machine learning and optical character recognition (OCR) to extract structured data, key-value pairs, and text from documents such as invoices, receipts, identity cards, and driver’s licenses.

This service allows businesses to automate data entry and document processing workflows by converting physical or scanned documents into machine-readable formats. For example, with a driver’s license, Form Recognizer can extract structured data fields such as Name, Date of Birth, License Number, and Expiration Date, and automatically populate those values into a database or CRM system.

The AI-900 study materials emphasize that Form Recognizer is designed to handle both structured and unstructured document layouts. It includes prebuilt models for common document types (like invoices, receipts, and identity documents) and supports custom models for domain-specific forms.

By comparison:

Computer Vision extracts general text or image content but doesn’t structure or label extracted fields.

Custom Vision is used for training image classification or object detection models.

Conversational Language Understanding is for processing text or speech to determine intent, not extracting document data.

Therefore, based on the Microsoft Learn AI-900 official study content, the Form Recognizer service is the correct choice, as it is explicitly designed to extract and structure data from documents like driver’s licenses, forms, and receipts — making it ideal for automatically populating a database.

According to the Microsoft Azure AI Fundamentals (AI-900) official study guide and the Microsoft Learn module “Identify features of computer vision workloads”, Optical Character Recognition (OCR) is a core capability within the computer vision domain that enables systems to detect and extract text from images or documents. OCR technology can identify printed or handwritten characters in photographs, scanned documents, or camera feeds, and convert them into machine-readable text.

In this scenario, the task is to read the numbers on runners’ shirts in race photos. These numbers are textual or numeric characters embedded within images. OCR is specifically designed for this purpose — to locate and recognize characters within visual data and convert them into usable text. Once extracted, those numbers can be cross-referenced with a database to identify each runner.

Let’s analyze why the other options are incorrect:

A. Facial recognition focuses on identifying individuals based on unique facial features, not reading text or numbers.

C. Semantic segmentation classifies each pixel of an image into categories (for example, separating road, sky, and people), but it doesn’t read text.

D. Object detection identifies and locates objects within an image (such as detecting people or vehicles) but does not extract readable text or numbers.

Therefore, since the task involves reading textual or numeric content from an image, the appropriate type of computer vision to use is Optical Character Recognition (OCR).
