Last Attempt CCAR-P Questions

Authentication and authorization run before retrieval so retrieval can filter by identity — Yes

An asynchronous queue absorbs bursty traffic between intake and the model-invocation layer — Yes

Tax computation is encoded directly in the system prompt rather than in code — No

Conversation logs include unredacted government identifiers to maximize tuning signal — No

Authentication and authorization must precede retrieval so unauthorized information never enters model context. An asynchronous queue is appropriate for burst absorption, backpressure, controlled concurrency, and retry management at scale. Deterministic tax computation should be implemented in validated code or a controlled calculation tool, not delegated to probabilistic prompt interpretation. Including unredacted government identifiers in conversation logs violates data-minimization principles and creates unnecessary privacy, security, and regulatory exposure. Sensitive fields should be removed, tokenized, or redacted before logging or model use unless specifically required and authorized. The resulting design separates deterministic computation, access control, scalable orchestration, and language reasoning into appropriate architectural layers.

A clearly defined closed-set classification task should begin with a concise zero-shot prompt containing the permitted categories, unambiguous category descriptions, and the required output structure. This provides a simple, inexpensive baseline that can be measured against a representative evaluation set. Chain-of-thought prompting adds unnecessary latency and token usage when the routing decision does not require substantive multi-step reasoning. Permitting Claude to invent categories would violate the closed-set contract and complicate downstream automation. Omitting descriptions would increase ambiguity among potentially overlapping labels. If evaluation later reveals persistent confusion between particular categories, the architect can introduce targeted examples or refine the definitions. Prompt complexity should be added in response to measured failure patterns, not assumed to be necessary before establishing baseline performance. Anthropic: Prompt engineering overview

Executive sponsors generally need architecture decisions translated into business significance. The briefing should explain what outcomes the retrieval architecture enables, why the chosen approach is valuable, which material trade-offs were accepted, and what major risks require awareness or sponsorship. This allows the executive to assess strategic alignment, investment value, and organizational exposure without becoming immersed in component-level implementation details. Option A is more appropriate for architects and engineering teams conducting a technical review. Option C is primarily suited to product and program stakeholders managing features, scope, and roadmap dependencies. Option D is designed for security, compliance, and risk-governance audiences requiring detailed control evidence. Although those perspectives remain important, option B provides the concise, outcome-oriented framing needed for an executive architectural decision summary.

Project scope is designed for repository-specific configuration shared through version control, including MCP server definitions, project permissions, hooks, and team instructions. This gives every contributor a consistent baseline while keeping changes reviewable. Managed configuration is appropriate for mandatory security and compliance controls because administrators can deploy it centrally and prevent lower scopes from overriding it. Local scope is machine-specific and unsuitable for organization-wide enforcement. User scope follows one engineer across projects, so it cannot guarantee that an entire team receives identical MCP definitions. Personal editor preferences belong in user or local configuration, not project scope, unless the team has explicitly standardized them. Anthropic’s settings hierarchy distinguishes managed, project, local, and user responsibilities. Claude Code settings
