Microsoft Azure AI Fundamentals Practice Test (AI-900)

This statement is False.

Regular updates and maintenance are essential for ensuring the reliability and safety of an AI solution after deployment. Over time, factors such as data drift, changes in user behavior, or new environmental conditions can affect the performance of an AI model. By continuously monitoring and updating the AI system, organizations can address these changes, fix emerging issues, and maintain the system's reliability and safety.

This statement is False.

Fairness in AI involves acknowledging and addressing the diverse needs and potential biases affecting different user groups. Treating all users identically without considering individual characteristics can perpetuate existing inequalities and lead to biased outcomes. Effective fairness strategies require assessing how different groups may be uniquely impacted and adjusting the AI solution to promote equity.

Using training data that represents a wide range of user groups and experiences helps ensure that the AI model performs fairly across different populations. This approach reduces bias and improves the equity of the AI solution, which are essential aspects of inclusiveness. While implementing advanced algorithms might enhance accuracy, it doesn't address potential biases in the data. Focusing solely on performance optimization may overlook the needs of diverse users. Designing the user interface with modern aesthetics enhances visual appeal but does not necessarily make the application more inclusive unless it also considers accessibility features.

This scenario represents a Generative AI workload because the system is generating new original artwork that imitates the style of existing artists. Generative AI focuses on producing new data that shares characteristics with the training data.

Computer Vision workloads involve interpreting and analyzing visual information but not generating new images.

Knowledge Mining workloads are about extracting insights from existing data, not creating new content.

Content Moderation workloads deal with identifying and filtering inappropriate content. Therefore, the most suitable workload in this case is Generative AI.

Sentiment analysis of customer reviews involves processing and understanding human language, which is a key aspect of natural language processing (NLP).

Recognizing objects in images is a computer vision task.

Predicting equipment failures using sensor data is related to predictive analytics.

Translating data into visual charts is data visualization.

Azure Form Recognizer is specifically designed to extract structured data from scanned documents like invoices and receipts. It uses machine learning models to identify and extract key-value pairs, text, and tables, transforming unstructured documents into structured data.

Azure Cognitive Search is used for indexing and searching over large sets of data but doesn't extract structured data from documents.

Azure Text Analytics processes unstructured text to detect sentiment, key phrases, and entities but doesn't work directly with scanned documents.

Azure Computer Vision Optical Character Recognition (OCR) extracts text from images but doesn't structure the data or extract key-value pairs as needed for invoices and receipts.

Computer Vision focuses on processing and interpreting visual information from images or videos. It is the most suitable choice for analyzing video surveillance to detect suspicious activities.

Natural Language Processing deals with understanding and generating human language, which is not applicable to visual data.

Knowledge Mining involves extracting insights from large volumes of structured and unstructured data, typically text-based.

Generative AI is concerned with creating new content rather than analyzing existing footage.

Natural Language Processing (NLP) is the AI workload that enables computers to understand, interpret, and generate human language. It is used to analyze textual data like customer reviews to determine sentiments and extract key topics.

Computer Vision is used for image and video analysis.

Knowledge Mining involves extracting structured information from large datasets but doesn't specialize in sentiment analysis of text.

Content Moderation focuses on detecting and filtering inappropriate content, not on sentiment analysis or topic extraction in text.

Knowledge Mining involves using AI to extract information from large volumes of unstructured data, such as documents, and making it accessible through search and analysis. It is the appropriate workload for extracting insights from unstructured documents and making them searchable.

Natural Language Processing (NLP) focuses on understanding and generating human language but does not specifically focus on making documents searchable.

Computer Vision deals with extracting information from images and videos.

Speech Recognition converts spoken language into text.

Accountability - This is the correct answer. Accountability ensures that AI systems are developed with mechanisms for oversight, and that organizations take responsibility for the outcomes produced by these systems. It involves ensuring that AI systems are used ethically and that their creators or operators are held responsible for their impact.

Transparency focuses on making AI systems understandable and providing visibility into how they work, but it doesn't directly address the mechanisms for oversight and responsibility for outcomes.

Inclusiveness is about ensuring that AI systems are designed to be fair and accessible, considering the diverse needs of users, but it is not specifically about oversight or accountability for outcomes.

Reliability and Safety focus on ensuring that AI systems perform as expected and do not cause harm, but accountability is the key consideration for ensuring oversight and responsibility for the system's outcomes.

Transparency involves making AI systems understandable and explainable to users and stakeholders. By enhancing transparency, the company allows users to comprehend how data is processed and how decisions are made, building trust in the system.

Privacy focuses on protecting personal and sensitive data, which is important but does not specifically address understanding AI decision-making processes.

Fairness aims to prevent biases and ensure equitable outcomes.

Inclusiveness ensures AI systems are accessible and beneficial to diverse users.

Obtaining explicit consent from users and adhering to relevant data protection laws like GDPR is the best approach to ensure compliance when processing personal data. This involves informing users about how their data will be used and ensuring all data handling practices meet legal requirements. While encryption, data anonymization, and restricting data collection are important measures, they alone may not fulfill all legal obligations under privacy laws.

Include a diverse set of data points representing different demographic groups - This is the correct answer. To promote fairness in an AI solution for loan approvals, it is crucial to include a diverse set of data points that represent various demographic groups. This helps the model learn from a wide range of experiences and ensures that the system does not disproportionately favor or disadvantage any particular group.

Exclude sensitive attributes like race and gender from the training data - While excluding sensitive attributes like race and gender can prevent direct bias, it may not be enough to ensure fairness.

Use historical data without modification to reflect real-world trends - Using historical data without modification might perpetuate existing biases in the data.

Prioritize algorithm efficiency over data diversity - While efficiency is important, prioritizing it over data diversity can lead to biased or incomplete models.

Azure Personalizer is designed to provide personalized experiences by learning from user behavior and preferences, making it the best choice for suggesting content based on individual interactions.

Azure Content Moderator is used for detecting and filtering inappropriate content.

Azure Cognitive Search provides indexing and search capabilities.
