AI-900 Reviews Questions

The correct answers are derived from the Microsoft Azure AI Fundamentals (AI-900) Official Study Guide and the Microsoft Learn module “Identify guiding principles for responsible AI.”

Microsoft defines six core principles of Responsible AI:

Fairness

Reliability and safety

Privacy and security

Inclusiveness

Transparency

Accountability

Each principle addresses a key ethical and operational requirement for developing and deploying trustworthy AI systems.

Reliability and safety – “AI systems must consistently operate as intended, even under unexpected conditions.”This principle ensures that AI models are dependable, robust, and perform accurately under diverse circumstances. Microsoft emphasizes that systems should be thoroughly tested and monitored to guarantee predictable behavior, prevent harm, and maintain safety. A reliable AI solution should continue to function properly when faced with unusual or noisy inputs, and fail safely when issues arise. This principle focuses on stability, testing, and dependable performance.

Privacy and security – “AI systems must protect and secure personal and business information.”This principle ensures that AI systems comply with data privacy laws and ethical standards. It protects users’ sensitive data against unauthorized access and misuse. Microsoft highlights that organizations must implement strong encryption, data anonymization, and access control mechanisms to maintain confidentiality. Protecting user data is essential to building trust and compliance with global standards like GDPR.

Other principles such as fairness and inclusiveness apply to ensuring equitable and accessible AI, but they do not directly relate to system operation or information protection.

✅ Final Answers:

“Operate as intended” → Reliability and safety

“Protect and secure information” → Privacy and security

Box 1: 11

TP = True Positive.

The class labels in the training set can take on only two possible values, which we usually refer to as positive or negative. The positive and negative instances that a classifier predicts correctly are called true positives (TP) and true negatives (TN), respectively. Similarly, the incorrectly classified instances are called false positives (FP) and false negatives (FN).

Box 2: 1,033

FN = False Negative

According to the Microsoft Azure AI Fundamentals (AI-900) Official Study Guide and the Microsoft Learn module “Explore computer vision in Microsoft Azure,” there are multiple types of computer vision tasks, each designed for different goals such as recognizing, categorizing, or locating objects within an image.

In this question, the application performs two distinct tasks: locating birds within an image and identifying their species. Each of these corresponds to a different type of computer vision capability.

Locate the birds → Object detection

Object detection is used when an AI system needs to identify and locate multiple objects within a single image.

It not only recognizes what the object is but also provides bounding boxes that indicate the exact position of each object.

In this scenario, locating the birds (drawing rectangles around each bird) is achieved through object detection models, such as those available in the Azure Custom Vision Object Detection domain.

Identify the species of the birds → Image classification

Image classification focuses on identifying what is in the image rather than where it is.

It assigns a single label (or multiple labels in multilabel classification) to an entire image based on its contents.

In this case, determining the species of a bird (e.g., robin, eagle, parrot) is achieved through image classification, where the model compares visual features against learned patterns from training data.

Incorrect options:

Automated captioning generates descriptive sentences about an image, not object locations or classifications.

Optical character recognition (OCR) extracts text from images, irrelevant in this case.

In a Language Understanding (LUIS) application, an utterance represents an example of what a user might say to the bot. According to Microsoft Learn – “Build a Language Understanding app”, an utterance is a sample phrase that helps train the LUIS model to recognize user intent.

In the given example — “Which act is playing on the main stage?” — the statement is an utterance that a user might say to find out about show schedules. LUIS uses utterances like this to identify the intent (the user’s goal, e.g., GetShowInfo) and to extract any entities (e.g., main stage) that provide additional details for fulfilling the request.

To clarify the other elements:

Intent: The overall purpose or action (e.g., “FindShowDetails”).

Entity: Specific information in the utterance (e.g., “main stage”).

Domain: A general subject area (e.g., entertainment, events).

Thus, “Which act is playing on the main stage?” is an utterance used to train the LUIS model to understand natural language input.
