Question 1

A developer wants to integrate a pre-built AI model that can extract key information from invoices, such as vendor name, invoice date, and total amount. Which Azure AI service should they use?

Accepted Answer

Azure AI Document Intelligence. Azure AI Document Intelligence (formerly Form Recognizer) is the correct service because it is specifically designed to extract structured data from documents like invoices, including fields such as vendor name, invoice date, and total amount. It uses pre-built models trained on common document types, making it ideal for this use case without requiring custom training.

Answer

Azure AI Language

Answer

Azure OpenAI Service

Answer

Azure Cognitive Search

Question 2

An organization is deploying a conversational AI solution using Azure OpenAI. They want to ensure the model's responses are grounded in their own knowledge base documents to reduce hallucinations. Which approach should they implement?

Accepted Answer

Integrate Azure Cognitive Search for retrieval-augmented generation (RAG). Option A is correct because Retrieval-Augmented Generation (RAG) with Azure Cognitive Search allows the model to dynamically retrieve relevant chunks from the organization's knowledge base documents at inference time. This grounds responses in authoritative, up-to-date content, directly reducing hallucinations by providing factual context rather than relying solely on the model's parametric memory.

Answer

Fine-tune the model on the knowledge base documents

Answer

Implement Azure AI Content Safety filters

Answer

Use prompt engineering to instruct the model to only use the knowledge base

Question 3

Which TWO actions are required to enable a custom chatbot built with Azure OpenAI to answer questions based on a company's internal PDF documents?

Accepted Answer

Ingest the PDFs into an Azure Cognitive Search index. Option D is correct because Azure Cognitive Search provides the indexing and retrieval capabilities needed to make PDF content searchable. By ingesting PDFs into an Azure Cognitive Search index, the chatbot can perform vector or keyword searches over the extracted text, enabling it to retrieve relevant passages to answer user questions. This is the standard approach for grounding a custom chatbot on proprietary documents without modifying the underlying model.

Answer

Use Azure AI Document Intelligence to extract text from PDFs before indexing

Answer

Deploy Azure AI Content Safety to filter responses

Answer

Fine-tune the GPT model on the PDF content

Question 4

You are a data scientist at a healthcare company. You have deployed a GPT-4 model using Azure OpenAI to answer patient inquiries about medical conditions. The model is configured with temperature=0.3 and max_tokens=200. Recently, the compliance team flagged that some responses contain contradictory information compared to the official medical guidelines. You need to ensure the model's answers align strictly with the provided medical documents (stored as PDFs in Azure Blob Storage). You have access to Azure Cognitive Search and Azure AI Document Intelligence. The solution must minimize hallucinations and not require retraining the model. What should you do?

Accepted Answer

Index the medical PDFs into Azure Cognitive Search. Configure the Azure OpenAI deployment to use 'Add your data' pointing to this index. Set the system message to instruct the model to base answers only on the retrieved context.. Option B is correct because it uses Azure Cognitive Search to index the medical PDFs and then configures the Azure OpenAI deployment with 'Add your data' to retrieve relevant context from that index at inference time. This retrieval-augmented generation (RAG) approach grounds the model's answers in the official documents without retraining, directly addressing the compliance team's requirement to align responses with the provided guidelines and minimize hallucinations.

Answer

Use prompt engineering to add a system message that tells the model to only answer based on the uploaded PDFs. Keep the current deployment.

Answer

Fine-tune GPT-4 on the medical documents using Azure OpenAI fine-tuning capabilities. Use the fine-tuned model for the chatbot.

Answer

Deploy Azure AI Content Safety to filter responses that contradict guidelines. Set up a custom content filter using a list of approved phrases.

Question 5

A company is deploying a generative AI solution using Azure OpenAI Service to generate product descriptions. The solution must comply with responsible AI principles, specifically ensuring that generated content does not include harmful or offensive language. Which Azure AI service feature should they implement to automatically filter the output?

Accepted Answer

Enable the default content filtering system in Azure OpenAI Service.. Option A is correct because Azure OpenAI Service includes a built-in default content filtering system that automatically screens generated outputs for harmful or offensive language, aligning with responsible AI principles. This system operates at the service level without additional configuration, making it the simplest and most direct way to filter product descriptions for compliance.

Answer

Configure Prompt Shields in Azure AI Content Safety.

Answer

Use Azure AI Content Safety with a custom category severity threshold.

Answer

Use groundedness detection in Azure AI Content Safety.

Question 6

A developer is using Azure OpenAI to generate code snippets. The developer needs to ensure that the generated code does not contain security vulnerabilities. Which TWO actions should the developer take? (Choose two.)

Accepted Answer

Include examples of secure coding practices in the prompt.. Option A is correct because including examples of secure coding practices in the prompt (few-shot prompting) directly guides the model to generate code that follows those patterns. This technique leverages in-context learning, where the model uses the provided examples to shape its output, reducing the likelihood of producing insecure code without requiring fine-tuning or external filtering.

Answer

Set the max_tokens parameter to a high value to allow longer outputs.

Answer

Fine-tune the model on a dataset containing examples of insecure code.

Answer

Add a system message that instructs the model to never generate insecure code.

Question 7

Refer to the exhibit. The developer is using Azure OpenAI with data sources (preview) to ground the model on a custom dataset. The assistant response includes a citation [^1]. However, the developer notices that the citation does not appear in the final output displayed to the user. What is the most likely cause?

Accepted Answer

The 'include_contexts' parameter in the API call is set to false.. Option A is correct because the 'include_contexts' parameter controls whether citation metadata from the data sources is included in the final output. When set to false, the API suppresses the citation markers (e.g., [^1]) even though the underlying context was used to generate the response. This is a preview feature of Azure OpenAI with your own data, where the citation rendering is explicitly gated by this parameter.

Answer

The citation format [^1] is not supported in Azure OpenAI with data sources.

Answer

The system message overrides the citation rendering.

Answer

The 'context' object in the assistant response is not being passed back in the prompt for the next turn.

Question 8

Drag and drop the steps to configure a multi-region disaster recovery for Azure Cognitive Services into the correct order.

Question 9

Drag and drop the steps to build and deploy a custom Azure AI Document Intelligence model into the correct order.

Question 10

Match each Azure Cognitive Search skill to its capability.

Question 11

Match each Azure Bot Service channel to its description.

Question 12

A company uses Azure OpenAI Service to generate product descriptions. They notice that the descriptions sometimes contain factually incorrect information. Which strategy should they use to reduce hallucinations?

Accepted Answer

Implement Retrieval-Augmented Generation (RAG) by grounding prompts with a knowledge base.. Option B is correct because Retrieval-Augmented Generation (RAG) grounds the model's output in a trusted, external knowledge base, providing factual context that directly reduces hallucinations. By retrieving relevant documents and injecting them into the prompt, the model generates responses based on verified information rather than relying solely on its parametric memory, which is the primary cause of factual inaccuracies in Azure OpenAI Service.

Answer

Increase the temperature parameter to 1.0.

Answer

Reduce the max_tokens parameter to limit output length.

Answer

Add a system message instructing the model to be more careful.

Question 13

You are designing a generative AI solution that uses Azure OpenAI GPT-4 to answer customer support questions. The solution must comply with Microsoft's Responsible AI principles, particularly transparency and accountability. Which implementation approach best meets these requirements?

Accepted Answer

Enable content filtering, log all interactions, and include a disclaimer that responses are AI-generated.. Option C is correct because it directly addresses Microsoft's Responsible AI principles of transparency and accountability. Enabling content filtering (via Azure AI Content Safety) ensures harmful outputs are blocked, logging all interactions provides an audit trail for accountability, and including a disclaimer that responses are AI-generated satisfies transparency by clearly informing users they are interacting with an AI system.

Answer

Use the model without any modifications, and have a human review all responses.

Answer

Fine-tune the model on a curated dataset of support tickets and disable content filtering.

Answer

Use the default model deployment and rely on the model's inherent safety.

Question 14

You need to generate realistic synthetic data for training a machine learning model while ensuring the data does not contain personally identifiable information (PII). Which Azure service should you use?

Accepted Answer
