Explanation:
Yes, Yes, No.
According to the Microsoft Azure AI Fundamentals (AI-900) study materials, conversational AI enables applications, websites, and digital assistants to interact with users via natural language. A chatbot is a key conversational AI workload and can be integrated into multiple channels such as web pages, Microsoft Teams, Facebook Messenger, and Cortana using Azure Bot Service and Bot Framework.
* "A restaurant can use a chatbot to answer queries through Cortana" - Yes.Azure Bot Service supports multi-channel deployment, which includes Cortana integration. This means the same bot can respond to voice or text input via Cortana, making it a valid use case for a restaurant to provide menu details, reservations, or order tracking through voice-based AI assistants.
* "A restaurant can use a chatbot to answer inquiries about business hours from a webpage" - Yes.This is a standard scenario for chatbots embedded on a company website. As per Microsoft Learn's Describe features of conversational AI module, a chatbot can be added to a website to handle FAQs such as business hours, location, or menu details, thereby improving response time and reducing repetitive human workload.
* "A restaurant can use a chatbot to automate responses to customer reviews on an external website" - No.Azure bots and other conversational AI tools cannot automatically interact with or post on external third-party platforms where the business does not control the data or API integration. Automated posting or replying to reviews on external review sites (e.g., Yelp or Google Reviews) would violate both ethical and technical boundaries of responsible AI usage outlined by Microsoft.

Explanation:

Box 1: Yes
Automated machine learning, also referred to as automated ML or AutoML, is the process of automating the time consuming, iterative tasks of machine learning model development. It allows data scientists, analysts, and developers to build ML models with high scale, efficiency, and productivity all while sustaining model quality.
Box 2: No
Box 3: Yes
During training, Azure Machine Learning creates a number of pipelines in parallel that try different algorithms and parameters for you. The service iterates through ML algorithms paired with feature selections, where each iteration produces a model with a training score. The higher the score, the better the model is considered to " fit " your data. It will stop once it hits the exit criteria defined in the experiment.
Box 4: No
Apply automated ML when you want Azure Machine Learning to train and tune a model for you using the target metric you specify.
The label is the column you want to predict.

Explanation:
Statement
Yes / No
Providing an explanation of the outcome of a credit loan application is an example of the Microsoft transparency principle for responsible AI.
Yes
A triage bot that prioritizes insurance claims based on injuries is an example of the Microsoft reliability and safety principle for responsible AI.
Yes
An AI solution that is offered at different prices for different sales territories is an example of the Microsoft inclusiveness principle for responsible AI.
No
This question is based on the Responsible AI principles defined by Microsoft, which are part of the AI-900 Microsoft Azure AI Fundamentals curriculum. Microsoft's Responsible AI framework consists of six key principles: Fairness, Reliability and Safety, Privacy and Security, Inclusiveness, Transparency, and Accountability. Each principle ensures that AI systems are developed and used in a way that benefits people and society responsibly.
* Transparency Principle - YesProviding an explanation for a loan decision aligns with the Transparency principle. Microsoft defines transparency as helping users and stakeholders understand how AI systems make decisions. For example, when a credit scoring AI model approves or denies a loan, explaining the factors that influenced that outcome (such as credit history or income level) ensures that customers understand the reasoning process. This builds trust and supports responsible deployment.
* Reliability and Safety Principle - YesA triage bot that prioritizes insurance claims based on injury severity relates directly to Reliability and Safety. This principle ensures AI systems operate consistently, perform accurately, and produce dependable outcomes. In the case of the triage bot, it must reliably assess the input data (injury descriptions) and rank claims appropriately to avoid harm or misjudgment, aligning with Microsoft's emphasis on designing AI systems that are safe and robust.
* Inclusiveness Principle - NoAn AI solution priced differently across sales territories is not related to Inclusiveness. Inclusiveness focuses on ensuring accessibility and eliminating bias or exclusion for all users-especially those with disabilities or underrepresented groups. Pricing strategy is a business decision, not an inclusiveness issue. Therefore, this statement is No.
In summary, based on the AI-900 Responsible AI principles, the correct selections are:

The correct answer is B. a reduced workload for the customer service agents.
According to the Microsoft Azure AI Fundamentals (AI-900) official study guide and Microsoft Learn module "Describe features of common AI workloads", conversational AI solutions such as chatbots are primarily designed to automate repetitive and routine customer interactions. The key business value emphasized in these materials is operational efficiency-chatbots allow organizations to respond to a high volume of customer queries without relying solely on human agents. This results in reduced workload, lower operational costs, and faster response times.
Microsoft's AI-900 learning objectives highlight that AI can be applied to automate tasks that previously required human interaction. In the context of customer support, a webchat bot powered by Azure AI services (such as Azure Bot Service or Azure Cognitive Services for Language) can handle frequently asked questions like order status, password resets, or basic troubleshooting. This allows human agents to focus their time and skills on more complex issues that require empathy, reasoning, or decision-making-tasks that AI cannot yet handle as effectively.
Additionally, the AI-900 course materials explain that one of the measurable business benefits of deploying AI-driven chatbots is improved efficiency and scalability. Chatbots can handle thousands of simultaneous interactions, something that human teams cannot easily do. As a result, the organization experiences reduced operational pressure on support staff, improved customer satisfaction due to quicker responses, and optimized resource utilization.
Options A and C are incorrect because chatbots do not directly influence sales growth or product reliability.
While increased customer satisfaction might indirectly support sales, it is not the primary or guaranteed outcome of implementing a chatbot. Similarly, product reliability is tied to engineering quality, not customer service automation.
Therefore, based on the official AI-900 study materials and Microsoft Learn concepts, the best and verified answer is B. a reduced workload for the customer service agents.

In Azure Machine Learning designer, the Split Data module is specifically designed to divide a dataset into training and validation (or testing) subsets. The AI-900 study guide and the Microsoft Learn module "Split data for training and evaluation" explain that this module allows users to control how data is partitioned, ensuring that models are trained on one portion of the data and tested on unseen data to assess performance.
By default, the Split Data module uses a 70/30 or 80/20 ratio, meaning 70-80% of the data is used for training and the remaining 20-30% for validation or testing. This ensures the model's generalizability and prevents overfitting.
The other options serve different purposes:
* A. Select Columns in Dataset: Used to choose specific columns or features from a dataset.
* B. Add Rows: Combines multiple datasets vertically.
* D. Join Data: Combines datasets horizontally based on a common key.
Only Split Data performs the function of dividing data into training and validation subsets.
