You are building an agent in Azure AI Foundry using a prompt flow. You need to ensure that the agent only uses company-approved documentation for its responses. Which feature should you implement to meet this requirement?
Grounding with data binds the model's responses to a specified index of company-approved documentation, retrieving passages at query time rather than relying on parametric knowledge. This directly satisfies the constraint that responses draw only from approved sources, since ungrounded generation could surface arbitrary content.
Why this answer
Grounding with data (e.g., Azure AI Search index, Azure Blob, or other approved data sources) constrains the model's responses to a curated knowledge base, ensuring the agent only answers from company-approved documentation. This is the standard RAG pattern in Azure AI Foundry and directly satisfies the 'only approved documentation' requirement.
Exam trap
AI-103 often tests the confusion between grounding (retrieval-based restriction to approved data) and fine-tuning (behavior/style adaptation) — candidates pick fine-tuning thinking it 'teaches' the model company data, but fine-tuning does not provide verifiable, updatable grounding.
How to eliminate wrong answers
Option A is wrong because prompt tuning adjusts the prompt template/parameters but does not restrict the model's knowledge source — the model can still hallucinate or use pretrained knowledge. Option B is wrong because system message constraints are soft instructions the model may ignore and do not enforce a data boundary. Option D is wrong because fine-tuning bakes in behavior/style but does not guarantee the model only cites approved documents, and it is expensive and slow to update when docs change.
