Question 13
Section 3Which managed Google Cloud capability allows BUILDERS to add a prebuilt RAG experience to an application with minimal custom code?
Correct answer: A
Explanation
"Prebuilt RAG with Vertex AI Search" is the managed capability for adding retrieval-augmented generation with minimal custom code because it provides a ready-made search and grounding layer. It lets BUILDERS connect application data to a prebuilt RAG experience instead of assembling retrieval, ranking, and generation components themselves.
Why each option is right or wrong
A. Prebuilt RAG with Vertex AI Search
Vertex AI Search is the managed Google Cloud service that provides a ready-made retrieval layer for grounding generative responses, so builders can attach their data sources and use the built-in RAG workflow instead of coding retrieval, ranking, and prompt orchestration from scratch. In Google Cloud’s Vertex AI documentation, this is the prebuilt option for adding RAG-style search and answer generation with minimal custom application code, unlike a fully custom RAG pipeline built from separate components.
B. Cloud DNS
Cloud DNS manages domain name resolution, not document retrieval or grounded generation workflows.
C. Cloud Storage signed URLs
Cloud Storage signed URLs grant temporary object access, not a managed RAG application experience.
D. Cloud KMS
Cloud KMS handles encryption key management, not search, retrieval, or LLM grounding.
