CCAR-F Exam Dumps - Anthropic Claude Certified Architect Questions and Answers

Option A parallelizes independent precedent analysis while preserving centralized control. The coordinator can partition the 12 precedents into balanced groups, provide each worker with identical extraction and citation requirements, monitor completion or failure, and aggregate the structured results before invoking synthesis.

Anthropic’s multi-agent research architecture uses an orchestrator-worker pattern in which a lead agent coordinates specialized subagents operating in parallel. Parallel execution is valuable when tasks are substantially independent, as each precedent can be analyzed without waiting for the preceding case. Maintaining the fan-out at the coordinator also produces a clear execution trace showing each assignment, status, and returned result.

Option B introduces nested delegation and makes tool usage, permissions, failures, and costs harder for the coordinator to observe. Option C compounds those problems through recursive spawning and risks excessive agent and token consumption. Option D may be appropriate for a large distributed processing platform, but it adds infrastructure without inherently improving the coordinator’s reasoning-level observability or defining how results are associated with the case. Coordinator-managed parallel workers provide the required latency reduction with the simplest debuggable architecture.

================

Option C matches the distinction between reasoning about delegation and executing it. Defining subagents makes their descriptions available for selection, but the coordinator must still invoke the SDK’s subagent-spawning tool. Current Claude Agent SDK documentation calls this the Agent tool; Task was its earlier name and remains relevant to older SDK configurations. Anthropic’s Subagents in the SDK documentation instructs developers to include Agent in allowedTools so subagent invocations are approved automatically. Without that permission, an invocation can fall through to a permission callback or be denied under a non-interactive permission mode. Option A is unlikely because the configured subagent descriptions already tell Claude when each agent should be selected, although explicit prompting can improve invocation reliability. Option B misstates context isolation: context must be included in the spawning prompt, but that issue occurs after an invocation is attempted and does not explain the absence of all subagent executions. Option D would normally produce truncation evidence or incomplete output rather than consistent verbal promises with no tool call. The configuration should therefore permit Agent, explicitly request delegation where necessary, and log subagent invocation events.

================

Resuming preserves the prior architectural analysis, dependency mapping, and conversation history, avoiding the cost of repeating an hour of valid work. Anthropic states that resuming by session ID restores the agent’s full prior context, including files read, analysis performed, and decisions made. ( https://code.claude.com/docs/en/agent-sdk/sessions )

However, the session represents historical knowledge rather than a repository snapshot. Because three files changed externally, the agent must be told which files are affected and directed to re-read them before relying on earlier conclusions. Anthropic clarifies that sessions persist the conversation, not the filesystem. ( https://code.claude.com/docs/en/agent-sdk/sessions ) Targeted re-analysis updates the stale portion of the agent’s model while retaining the nine unchanged files’ established context.

Option A discards valuable work even though most of the analyzed code remains unchanged. Option C is accurate but inefficient because it reprocesses all twelve files regardless of whether they changed. Option D is unsafe: the agent may continue reasoning from obsolete function signatures, dependencies, or control flows.

The continuation prompt should identify the changed files, summarize the merge’s purpose where known, and request a focused comparison against the earlier understanding. Any architectural conclusions affected by those changes should then be revised explicitly.

Option C converts an empirically validated source hierarchy into an explicit extraction rule. The downstream contract requires one battery_capacity value, and historical analysis establishes that the detailed specifications table is substantially more reliable than the summary section. Claude should therefore be instructed to inspect all occurrences, detect conflicts, and select the detailed-table value when the two locations disagree.

Anthropic’s prompting guidance emphasizes clear, direct instructions, relevant context, and explicit decision rules when order or completeness matters. Providing the reason for the precedence rule also helps the model generalize it to comparable specification conflicts. Option A preserves every value but transfers a known and repeatable decision into downstream systems, unnecessarily changing the schema. Option B rejects approximately 15% of otherwise processable documents even though a reliable precedence policy is available. Option D creates a costly manual-review queue for conflicts that can usually be resolved deterministically. The extraction system should still retain source quotations or locations in internal provenance metadata when auditability matters, but the output field should follow the established detailed-table precedence. Anthropic prompting best practices

Option C parallelizes independent work while retaining centralized orchestration. Each precedent can be analyzed without waiting for the previous precedent, so the coordinator can divide the 12 cases into balanced subsets and invoke several document-analysis subagents concurrently. It then receives their final outputs, records which precedents completed or failed, and aggregates the results before synthesis. Anthropic’s multi-agent research architecture uses an orchestrator-worker pattern in which the lead agent creates specialized subagents that operate in parallel and return findings for consolidation. Keeping spawning decisions at the coordinator also produces a clearer execution trace for monitoring and debugging. A generic asynchronous queue, option A, adds infrastructure but does not define how results remain associated with the correct research task. Options B and D create nested or recursive delegation, making execution paths, permissions, failures, and token consumption harder to observe. Anthropic also cautions that multi-agent systems consume substantially more tokens than ordinary interactions, so unbounded recursive decomposition is inefficient. Coordinator-controlled parallel fan-out followed by deterministic aggregation provides the latency improvement without sacrificing operational visibility.

================

Option C directly searches source-file contents for imports of @company/auth . Anthropic’s Claude Code tools reference states that Grep locates patterns within files, while Glob matches filenames and paths. The search can account for the repository’s supported module syntaxes, including static imports, require() calls, dynamic imports, and re-exports. It can also restrict results by file type or directory when appropriate. Option A identifies packages that declare the dependency but does not prove which source files import or invoke it; workspace-level dependency declarations may cover many packages. Option B finds authentication-related filenames, which are unrelated to whether a file imports the package. Option D searches directory names and therefore has the same limitation. After Grep returns the matching files and line numbers, the agent can read the surrounding code to determine whether each import supports middleware registration, token verification, authorization checks, or re-exporting. This produces an accurate usage inventory while minimizing context consumption and unnecessary file reads.

================

Option B uses the tool designed to search file contents. Anthropic’s Claude Code tools reference distinguishes Grep from Glob: Grep searches lines inside files, whereas Glob matches filenames and paths. Grep is built on ripgrep and accepts regular-expression patterns, so the opening parenthesis should be escaped as eval\( when the intention is to match the literal function call. The search can return matching files, line numbers, and surrounding context without loading every file into the model’s context window. Option A searches filenames resembling eval , not source files whose contents invoke the function. Option C follows only code reachable from a selected entry point and can miss test utilities, dynamically loaded modules, scripts, and dormant vulnerable code. Option D combines a recursive filename listing with text filtering; it still searches names rather than file contents. After Grep identifies matches, the agent should use Read on the relevant ranges to distinguish actual executable calls from comments, strings, or safe wrappers. Grep therefore provides the most complete and context-efficient initial security scan.

The implementation approach is unresolved and carries architectural consequences. WebSockets, Server-Sent Events, and polling differ in connection lifecycle, bidirectional communication, proxy compatibility, scaling requirements, deployment topology, reconnection behavior, and operational complexity. Claude should therefore inspect the existing application and infrastructure before modifying code.

Anthropic recommends separating exploration and planning from implementation when the approach is uncertain, the work affects multiple files, or the developer is unfamiliar with the relevant architecture. In plan mode, Claude can read files and analyze the system without making changes, produce a detailed proposal, and allow the developer or team to review the plan before execution. ( https://code.claude.com/docs/en/best-practices )

Option A commits to polling before determining whether its latency and load characteristics meet the requirement. Option B delegates a consequential architectural decision and immediate implementation to a single execution step without a review checkpoint. Option D prematurely selects the most infrastructure-sensitive option and assumes later refactoring will be inexpensive.

Option C creates the correct sequence: examine the frontend and backend architecture, document requirements, compare alternatives, identify infrastructure constraints, obtain approval, and only then implement the selected design with appropriate tests and observability.

Resuming the existing subagent preserves the expensive investigative context: files already inspected, data-flow relationships, hypotheses, and intermediate conclusions. Anthropic documents that session history contains prompts, tool calls, tool results, and responses, allowing an interrupted investigation to continue with its prior analysis intact. ( https://code.claude.com/docs/en/agent-sdk/sessions ) Subagent transcripts also persist within their parent session and can be resumed after an interruption or restart. ( https://code.claude.com/docs/en/agent-sdk/subagents?utm_source=chatgpt.com )

The engineer must nevertheless disclose the renamed utility functions. Anthropic explicitly distinguishes conversation persistence from filesystem persistence: resuming restores what the agent previously knew, but it does not freeze or snapshot the repository. ( https://code.claude.com/docs/en/agent-sdk/sessions ) Without the update, the subagent may search for obsolete symbols, misinterpret broken references, or rely on stale file paths.

Option A loses the detailed transcript and replaces it with a necessarily compressed summary. Option B preserves context but conceals a material repository change. Option D duplicates a large transcript inside a new context, increasing token consumption without providing any advantage over native resume functionality.

The resumed prompt should name the renamed functions, identify the merge or affected files, and instruct the subagent to re-read only the changed areas before continuing its broader exploration.

The key difference is reviewer independence. In the original session, Claude retains the reasoning, assumptions, implementation decisions, and intermediate conclusions that led to the refactor. That context can anchor the subsequent review toward defending or confirming the chosen approach instead of evaluating the resulting code independently. The separate CI review begins with fresh context and can assess the implementation solely against the code and review criteria.

Anthropic’s Claude Code best-practices documentation explicitly states that fresh context improves code review because Claude is not biased toward code it has just written. It recommends a writer/reviewer pattern using separate sessions or a review subagent with an isolated context.

Option B is possible in an uncontrolled comparison, but the scenario’s defining distinction is that one review occurs in the implementation session and the other is independent. Option C is false because local Claude Code can read and search the repository when permissions and tools permit it; it is not inherently restricted to the current file. Option D would require evidence of context saturation, such as degraded instruction following or an almost-full context window. No such evidence is supplied. Prior-reasoning bias most directly explains the observed discrepancy.
