CCAR-P P3 practice. Some items are “select all that apply” — they tell you how many to pick and are graded all-or-nothing. Commit before revealing, then read every explanation.

  1. P3 · Q1RAG anatomy / pipeline order
    A team is drawing the reference architecture for a retrieval-augmented generation system. Which sequence correctly orders the core stages from raw source documents to a grounded answer?
  2. P3 · Q2Chunking strategy & failure modes
    A knowledge base of long technical manuals is chunked by splitting every 200 characters regardless of content. Users report answers that cut off mid-sentence and miss context that spans paragraphs. What is the most appropriate first fix?
  3. P3 · Q3Poor-answers triage / root cause
    A support RAG assistant returns a fluent, well-written answer that is factually wrong. Inspecting the trace shows the retrieved chunks did contain the correct policy text, but the model's answer contradicts it. All options below are plausible actions. What is the most likely root cause?
  4. P3 · Q4MCP fundamentals / roles
    In the Model Context Protocol, which statement correctly describes the relationship between host, client, and server?
  5. P3 · Q5Hybrid retrieval (dense + BM25)Select 2
    A team is adding hybrid retrieval (dense vectors plus BM25 keyword search) to improve recall on queries containing exact product codes and rare acronyms. Which TWO statements about this design are correct?
  6. P3 · Q6Data-layer authorization / ACL trap
    An enterprise RAG assistant indexes documents from multiple teams into one shared vector store. Legal requires that a user only ever see snippets from documents they are authorized to access. A dozen designs are on the table and all sound workable in a demo. What is the least risky way to enforce this?
  7. P3 · Q7Remote MCP + authSelect 2
    A company is exposing a remote MCP server over HTTP so that a hosted agent can call internal tools on behalf of individual employees. Which TWO practices best protect this integration?
  8. P3 · Q8Observability / tracing across hops
    A multi-step agent calls three MCP tools and two retrieval steps per request. Latency is spiking intermittently but logs only show the final answer and total wall-clock time. All of these could help; which is the most appropriate instrumentation to add first?
