Microsoft AI-900日本語 Actual Tests : Microsoft Azure AI Fundamentals (AI-900日本語版)

Correct Answer:

Explanation:

The correct matching aligns directly with the Microsoft Azure AI Fundamentals (AI-900) official study guide and Microsoft Learn modules under "Identify features of Azure Machine Learning". Azure Machine Learning provides a suite of tools that serve different functions within the model development lifecycle - from creating workspaces, to training models, to automating experimentation.
* The Azure portal # Create a Machine Learning workspace.The Azure portal is a web-based graphical interface for managing all Azure resources. According to Microsoft Learn, you use the portal to create and configure the Azure Machine Learning workspace, which acts as the central environment where datasets, experiments, models, and compute resources are organized. Creating a workspace through the portal involves specifying a subscription, resource group, and region - tasks that are part of the setup stage rather than model development.
* Machine Learning designer # Use a drag-and-drop interface used to train and deploy models.The Machine Learning designer (formerly "Azure ML Studio (classic)") provides a visual, no-code/low- code interface for building, training, and deploying machine learning pipelines. The designer uses a drag-and-drop workflow where users connect modules representing data transformations, model training, and evaluation. This tool is ideal for beginners and those who want to quickly experiment with machine learning concepts without writing code.
* Automated machine learning (Automated ML) # Use a wizard to select configurations for a machine learning run.Automated ML simplifies model creation by automatically selecting algorithms, hyperparameters, and data preprocessing options. Users interact through a guided wizard (within the Azure Machine Learning studio) that walks them through configuration steps such as selecting datasets, target columns, and performance metrics. The system then iteratively trains and evaluates multiple models to recommend the best-performing one.
Together, these tools streamline the machine learning workflow:
* Azure portal for setup and resource management,
* Machine Learning designer for visual model creation, and
* Automated ML for guided, automated model selection and tuning.

Explanation:
Yes, Yes, and No.
According to the Microsoft Azure AI Fundamentals (AI-900) official study materials and the Microsoft Learn module "Identify features of natural language processing (NLP) workloads on Azure", the Azure Translator service is a cloud-based AI service within Azure Cognitive Services that provides real-time text translation across multiple languages.
* "You can use the Translator service to translate text between languages." - Yes.This is the core function of the Translator service. It takes text as input in one language and returns it in another using advanced neural machine translation models. This aligns with the AI-900 learning objective: "Describe the capabilities of Azure Cognitive Services for language", which specifically names Azure Translator as the service used to perform automatic text translation. The service supports over 100 languages and dialects, offering both single-sentence and document-level translations.
* "You can use the Translator service to detect the language of a given text." - Yes.This statement is also true. The Translator service automatically detects the source language if it is not specified in the request. This feature is documented in the Azure Translator API, where the system identifies the input language before performing translation. The AI-900 exam content emphasizes this as one of the Translator service's built-in capabilities-language detection for untagged text.
* "You can use the Translator service to transcribe audible speech into text." - No.This is not a function of Translator. Transcription (converting speech to text) is a speech AI workload, handled by the Azure Speech Service, not Translator. The Speech-to-Text capability in Azure Cognitive Services processes spoken audio input and returns the text transcription. The Translator service only works with text input, not direct audio.
Therefore, based on official AI-900 guidance, the verified configuration is:
# Yes - for text translation
# Yes - for language detection
# No - for speech transcription.
This aligns precisely with the AI-900 learning outcomes describing Text Translation and Language Detection as Translator capabilities, and Speech Transcription as part of the separate Speech service.

Correct Answer:

Explanation:

The correct matches are Custom Vision, Form Recognizer, and Face - each corresponding to a distinct capability under Azure Cognitive Services as described in the Microsoft Azure AI Fundamentals (AI-900) official study guide and Microsoft Learn modules on Computer Vision workloads.
* Custom Vision # Identify objects in an imageThe Custom Vision service is part of the Azure Cognitive Services suite that enables developers to train custom image classification and object detection models.
Unlike the prebuilt Computer Vision API, Custom Vision allows users to upload their own labeled images and teach the model to recognize specific objects relevant to their business context. The AI-900 syllabus explains that Custom Vision is ideal for tasks such as identifying products on a shelf, categorizing images, or detecting defects in manufacturing.
* Form Recognizer # Automatically import data from an invoice to a databaseForm Recognizer is a document processing AI service that extracts structured data from forms, receipts, and invoices. It uses optical character recognition (OCR) combined with layout and key-value pair detection to automatically capture information such as invoice numbers, amounts, and vendor names. The AI-900 study materials highlight this service under the Document Intelligence category, emphasizing its ability to streamline data entry and business automation workflows by importing extracted data directly into databases or applications.
* Face # Identify people in an imageThe Face service provides advanced facial detection and recognition capabilities. It can locate faces in images, compare similarities between faces, identify known individuals, and even detect facial attributes such as age or emotion. The AI-900 course classifies this under Computer Vision services for person identification and security-related use cases such as access control or identity verification.
Thus, each mapping aligns precisely with the AI-900 official learning outcomes on Cognitive Services capabilities:
* Custom Vision # Object recognition
* Form Recognizer # Data extraction from forms
* Face # People identification
# Final verified configuration:
* Custom Vision # Identify objects in an image
* Form Recognizer # Automatically import data from an invoice to a database
* Face # Identify people in an image

Correct Answer:

Explanation:

These answers are derived from the Microsoft Azure AI Fundamentals (AI-900) Official Study Guide and the Microsoft Learn module "Explore computer vision in Microsoft Azure." The Azure Face service, part of Azure Cognitive Services, provides advanced facial recognition capabilities including detection, verification, identification, grouping, and similarity analysis.
Let's analyze each statement:
* "The Face service can be used to group all the employees who have similar facial characteristics." # YesThe Face service supports a grouping function that automatically organizes a collection of unknown faces into groups based on visual similarity. It doesn't require labeled data; instead, it identifies clusters of similar-looking faces. This is particularly useful when building or validating datasets of people.
* "The Face service will be more accurate if you provide more sample photos of each employee from different angles." # YesAccording to Microsoft documentation, model accuracy improves when you provide multiple high-quality images of each person under different conditions-such as varying lighting, poses, and angles. This diversity allows the service to better learn unique facial characteristics and improves recognition reliability, especially for identification and verification tasks.
* "If an employee is wearing sunglasses, the Face service will always fail to recognize the employee." # NoThis is incorrect. While occlusions (like sunglasses or hats) can reduce accuracy, the service may still recognize the person depending on how much of the face remains visible. Microsoft Learn explicitly notes that partial occlusion affects recognition confidence but does not guarantee failure.
In conclusion, the Face service can group similar faces (Yes), become more accurate with diverse samples (Yes), and still recognize partially covered faces though with lower confidence (No). These principles align directly with the Face API's core functions and AI-900 learning objectives regarding computer vision and responsible AI-based facial recognition.
