Microsoft AI-900 Online Practice Questions and Exam Preparation

Microsoft AI-900 Online Questions & Answers

• Question 181:

  Which Azure service can use the prebuilt receipt model in Azure Al Document Intelligence?

  A. Azure Al Computer Vision
  B. Azure Machine Learning
  C. Azure Al Services
  D. Azure Al Custom Vision
  C. Azure Al Services

• Question 182:

  A retailer wants to automatically categorize product images into groups such as shoes, shirts, and accessories.

  Which computer vision capability should be used?

  A. Image classification
  B. Object detection
  C. OCR
  D. Face detection
  A. Image classification

  ---

  Explanation

  Image classification assigns an image to a predefined category. It is useful when the goal is to categorize entire images rather than detect specific objects within them.

• Question 183:

  DRAG DROP

  You plan to deploy an Azure Machine Learning model as a service that will be used by client applications.

  Which three processes should you perform in sequence before you deploy the model? To answer, move the appropriate processes from the list of processes to the answer area and arrange them in the correct order.

• Question 184:

  A conference organizer collects written feedback from attendees and uses generative AI to summarize the responses. Some attendees cannot participate in audio discussions and only provide written comments.

  Which Responsible AI principle helps ensure the system treats all participants fairly?

  A. Fairness
  B. Reliability and safety
  C. Privacy and security
  D. Transparency
  A. Fairness

  ---

  Explanation

  The fairness principle ensures that AI systems treat all individuals equally and do not disadvantage certain groups. In this scenario, the system must fairly represent feedback regardless of whether it comes from spoken or written input.

• Question 185:

  What are two tasks that can be performed by using computer vision? Each correct answer presents a complete solution.

  NOTE: Each correct selection is worth one point.

  A. Predict stock prices.
  B. Detect brands in an image.
  C. Detect the color scheme in an image
  D. Translate text between languages.
  E. Extract key phrases.
  B. Detect brands in an image.
  C. Detect the color scheme in an image

  ---

  Explanation

  B: Azure's Computer Vision service gives you access to advanced algorithms that process images and return information based on the visual features you're interested in. For example, Computer Vision can determine whether an image contains adult content, find specific brands or objects, or find human faces.

  E: Computer Vision includes Optical Character Recognition (OCR) capabilities. You can use the new Read API to extract printed and handwritten text from images and documents. It uses the latest models and works with text on a variety of surfaces and backgrounds. These include receipts, posters, business cards, letters, and whiteboards. The two OCR APIs support extracting printed text in several languages.
