Exam AI-900 Topic 1 Question 73 Discussion

The correct answers are B. Import chit-chat content from a predefined data source, C. Manually enter the questions and answers, and E. Generate the questions and answers from an existing webpage.
According to Microsoft Learn and the Azure AI Fundamentals (AI-900) study guide, the Question Answering feature of the Azure AI Language Service (formerly part of QnA Maker) allows developers to create a knowledge base (KB) that enables a chatbot to answer common questions automatically. This knowledge base can be built in three main ways:
* Import chit-chat content (B):Azure provides predefined chit-chat datasets that can be imported to make a bot more conversational and natural. This includes small talk such as greetings, acknowledgments, and polite responses (for example, "How are you?" # "I'm doing great, thanks!"). Importing this content enriches the bot's personality and improves user engagement.
* Manually enter questions and answers (C):Developers can manually add pairs of questions and answers directly into the question answering knowledge base. This approach is suitable for custom FAQs or domain-specific content. It gives complete control over how each question is phrased and what answer is returned, ensuring high precision and clarity.
* Generate questions and answers from an existing webpage (E):Azure AI Language can automatically extract Q&A pairs from a website's FAQ or support page. This is done by providing the webpage URL to the service, which scans the page and builds a knowledge base from the detected questions and corresponding answers.
The other options are incorrect:
* A (Cortana channel) relates to bot deployment, not knowledge creation.
* D (Automated ML) is used for predictive modeling, not for building Q&A datasets.
Thus, the verified correct answers are B, C, and E.
