CCAR-P Study Guide

CCAR-P facts to memorise: 30 recall cards

Thirty facts that are pure recall — the ones you either know cold or lose a mark on. Cover the right-hand column and work down the list.

PromptWhat you need to know
Exam format63 scored questions, 120 minutes, 720/1,000 scaled. Standalone items, not scenario-anchored. No prerequisite.
Heaviest domainIntegration, 19% — ahead of Solution Design at 17%.
The new 35%Governance and Risk (14%), Stakeholder and Lifecycle (14%), Developer Enablement (7%) have no Foundations equivalent.
The defensibility testEvery decision needs a stated trade-off, a measurement, and an owner.
Before choosing a patternEstablish stakes, hard constraints (residency, latency, retention, regulation) and the success measure.
Workflow vs agent, at this levelAgentic systems are harder to bound, audit and cost-forecast — often decisive in a regulated context.
Guardrail layers, strongest firstArchitectural · deterministic validation · model screening · prompt-level · human review.
Identity in integrationsPropagate the caller's identity to the data layer. One privileged service account means any user can get any row.
Deployment surface choiceA compliance decision: IAM-based auth, existing billing, invocation logging, and regional endpoints for residency.
RAG chunking failureChunks stripped of context — "revenue grew 3%" with no company and no quarter.
Contextual enrichmentPrepend a short generated description situating each chunk in its document. Prompt caching makes it economic.
Why hybrid retrievalEmbeddings miss exact identifiers and rare terms; BM25 misses paraphrase.
RerankingRetrieve broadly, score, keep the best. Raises relevance, adds latency, can cut generation cost.
Retrieval improvement figuresContextual enrichment + hybrid ≈ 49% fewer top-20 retrieval failures; adding reranking ≈ 67%.
CitationsStructured pointers: cited_text, document_index, char/page/block location. cited_text is free on output. Not compatible with strict structured output.
Hallucination in RAGCheck retrieval first — often the model answered faithfully from chunks lacking the answer.
Observability per requestrequest_id · model and prompt version · stop_reason · full usage · TTFT and total · tool calls · retrieved vs cited · validation and guardrail outcomes · escalations · cost attribution.
Earliest drift signalHuman override and escalation rate — infrastructure metrics stay flat while quality falls.
Safe change sequenceOffline evals → shadow run → A/B with limited exposure → rollout. One variable at a time.
Shadow vs A/BShadow gives production distribution with zero user exposure; A/B gives real outcomes at the cost of exposure.
LLM-as-judgeValidate against human labels first. Specific empirical rubric, parseable output, reasoning before score.
Eval volume100+ cases; 1,000+ for production. Refresh from real traffic as the distribution shifts.
Anthropic certificationsSOC 2 Type I and II · ISO/IEC 27001:2022 · ISO/IEC 42001:2023 (AI management) · HIPAA-ready with BAA.
Vendor certificationAn input to your compliance case, never a substitute. Lawful basis, minimisation, retention, access control and audit evidence stay yours.
Commercial data handlingTeam, Enterprise and API content not used for training by default; zero data retention arrangements available.
High-risk domainsLegal · healthcare · insurance · financial advice · employment · housing and lending · academic assessment · journalism.
Human review designTriage which cases · give reviewers evidence and citations · measure override rate · size the queue. A backlogged review is no review.
Over-refusalA quality failure, not a safety win — users route around a system that declines legitimate work.
SLA: can commitAvailability · latency percentiles · accuracy against a defined eval set · escalation turnaround · time to detect degradation.
SLA: cannot commitCorrectness on arbitrary inputs · that degradation will not occur. Your availability is bounded by provider + retrieval + your own infrastructure.
