Microsoft Azure AI Fundamentals (AI-900中文版) Sample Questions:
您有一個可以預測產品品質的 Azure 機器學習模型。該模型有一個包含 50,000 筆記錄的訓練資料集。下表顯示了數據範例。
對於以下每條語句，如果該語句為真，請選擇「是」。否則，選擇否。
注意：每個正確的選擇都值得一分。
Correct Answer:
Explanation:
This question tests the understanding of features and labels in machine learning, a core concept covered in the Microsoft Azure AI Fundamentals (AI-900) syllabus under "Describe fundamental principles of machine learning on Azure." In supervised machine learning, data is divided into features (inputs) and labels (outputs).
* Features are the independent variables - measurable properties or characteristics used by the model to make predictions.
* Labels are the dependent variables - the target outcome the model is trained to predict.
From the provided dataset, the goal of the Azure Machine Learning model is to predict product quality (Pass or Fail). Therefore:
* Mass (kg) is a feature - Yes"Mass (kg)" represents an input variable used by the model to learn patterns that influence product quality. It helps the algorithm understand how variations in mass might correlate with passing or failing the quality test. Thus, it is correctly classified as a feature.
* Quality Test is a label - YesThe "Quality Test" column indicates the outcome of the manufacturing process, marked as either Pass or Fail. This is the target the model tries to predict during training. In Azure ML terminology, this column is the label, as it represents the dependent variable.
* Temperature (C) is a label - No"Temperature (C)" is an input that helps the model determine quality outcomes, not the outcome itself. It influences the quality result but is not the value being predicted.
Therefore, temperature is another feature, not a label.
In conclusion, per Microsoft Learn and AI-900 study materials, features are measurable inputs (like mass and temperature), while the label is the target output (like the quality test result).

Explanation:
Classification
According to the Microsoft Azure AI Fundamentals (AI-900) official study guide and the Microsoft Learn module "Describe features of common AI workloads", classification is a supervised machine learning technique used when the goal is to predict which category or class an item belongs to. In supervised learning, the model is trained with labeled data-data that already contains known outcomes. The system learns patterns and relationships between input features and their corresponding labels so it can predict future classifications accurately.
In the scenario provided - "A banking system that predicts whether a loan will be repaid" - the model's output is a binary decision, meaning there are two possible outcomes:
* The loan will be repaid (positive class)
* The loan will not be repaid (negative class)
This kind of problem involves predicting a discrete value (a label or category), not a continuous numeric output. Therefore, it perfectly fits the classification type of machine learning.
The AI-900 learning materials describe classification as being used in many real-world examples, including:
* Determining whether an email is spam or not spam.
* Predicting whether a customer will churn (leave) or stay.
* Detecting fraudulent transactions.
* Assessing medical test results as positive or negative.
By contrast:
* Regression predicts continuous numeric values, such as predicting house prices, temperatures, or sales revenue. It would not apply here because repayment prediction is not a numeric value but a categorical decision.
* Clustering is an unsupervised learning method that groups similar data points without predefined categories, such as segmenting customers by purchasing behavior.
Thus, based on Microsoft's Responsible AI and AI-900 study guide concepts, a banking system that predicts whether a loan will be repaid uses the Classification type of machine learning.

Correct Answer:
Explanation:
facial analysis.
According to the Microsoft Azure AI Fundamentals (AI-900) official study guide and the Microsoft Learn module "Describe features of computer vision workloads on Azure," facial analysis is a computer vision capability that detects faces and extracts attributes such as facial expressions, emotions, pose, occlusion, and image quality factors like exposure and noise. It does not identify or verify individual identities; rather, it interprets facial features and image characteristics to analyze conditions in an image.
In this question, the AI solution helps photographers take better portrait photos by providing feedback on exposure, noise, and occlusion - tasks directly linked to facial analysis. The model analyzes the detected face to determine if the image is well-lit, clear, and unobstructed, thereby improving photo quality. These capabilities are part of the Azure Face service in Azure Cognitive Services, which includes both facial detection and facial analysis functionalities.
Here's how the other options differ:
* Facial detection only identifies that a face exists in an image and provides its location using bounding boxes, without further interpretation.
* Facial recognition goes a step further - it attempts to identify or verify a person's identity by comparing the detected face with stored images. This is not what the scenario describes.
Thus, when an AI solution evaluates image quality aspects like exposure, noise, and occlusion, it's performing facial analysis, which focuses on understanding image and facial characteristics rather than identification.
In summary, based on Microsoft's AI-900 study material, this scenario demonstrates facial analysis, a subcategory of computer vision tasks within Azure Cognitive Services.
對於以下每個陳述，如果該陳述為真，請選擇「是」。否則，選擇“否”。 注意：每個正確的選擇都值得一分。
Correct Answer:
Explanation:
"Generative AI enables software applications to generate new content, such as language dialogs and images."
- YES
This statement is true. According to the Microsoft Azure AI Fundamentals (AI-900) study guide and Microsoft Learn documentation, Generative AI refers to systems capable of creating new content such as text, audio, images, video, and code. Models like GPT, DALL E, and Codex use deep learning to generate human- like responses, natural conversations, or creative media. This is a key differentiator between generative and discriminative AI - generative AI produces new data, while discriminative AI categorizes or analyzes existing data.
"The difference between a large language model (LLM) and a small language model (SLM) is the number of variables in the model." - YES This statement is true. The primary distinction between an LLM and an SLM lies in the scale of parameters (variables) within the neural network. LLMs contain billions or even trillions of parameters, which enable them to capture complex linguistic patterns and perform broader tasks. SLMs have fewer parameters, making them faster but less capable of handling complex, context-rich tasks.
"Generative AI is a type of supervised learning." - NO
This statement is false. Generative AI models are typically trained using unsupervised or self-supervised learning methods. They learn by predicting missing or next elements in large text or image datasets rather than relying on labeled input-output pairs, which are used in supervised learning.
