An Agentforce Specialist at Cloud Kicks wants to build a retrieval-augmented generation (RAG) powered agent...

The correct answer is B. Agentforce Data Library is Salesforce’s quick-start RAG option for grounding agents in trusted unstructured content such as files and Knowledge articles. When a data library is added, Salesforce automatically builds the default RAG components behind the scenes, including the vector data store, search index, retriever, prompt template, and standard action. Option A is wrong because an ensemble retriever is used when searching across multiple retrievers or sources; it is not the quick-start feature that creates the whole RAG pipeline. Option C is wrong because a search index is only one component of the pipeline. The scenario explicitly asks for a feature that automatically provisions all underlying parts, which is precisely the purpose of Agentforce Data Library.
