Anthropic CCA-F Practice Test 14
Question 130
Parallel research agents produce findings with conflicting terminology for the same product. What decomposition stage is missing?
- Keep the small tightly coupled writing task within one agent
- Split first by jurisdictional coverage, then by relevant regulation topics within each
- A normalization and cross-source reconciliation pass after individual workstreams
- Use explicit prompt chaining or a fixed workflow with stage-by-stage validation
Explanation
Correct Answer
C:Parallel research increases throughput but does not guarantee consistent terminology. A dedicated synthesis stage resolves incompatibilities before publication. Normalize equivalent product names and units before combining the independent analyses. Preserve each original term and citation so a synonym mapping does not conceal a genuinely different product specification.
Incorrect Answers
A:One-agent writing can preserve tone in a short document, but these independent research agents have already produced terms that conflict for the same product. The next step is an explicit terminology and evidence reconciliation pass before synthesis, not collapsing unrelated research into a single writer.
B:Splitting legal research by jurisdiction organizes geographical coverage, but the disagreement here is inconsistent product terminology across already completed parallel workstreams. That partition does not reconcile whether two labels refer to one entity. Normalize entity definitions and sources before combining findings.
D:A fixed-stage prompt chain can enforce processing order, but it does not resolve conflicting names or measurements returned by independent agents. The coordinator needs to compare terms to a canonical glossary and verify source equivalence before presenting a merged product conclusion.
Question 131
A support system receives billing, technical and legal questions with different required evidence. What decomposition approach is appropriate?
- Route billing, technical and legal requests to the billing-only specialist regardless of the customer's issue
- Classify the request and dispatch it into domain-specific workflow branches
- Route the uncertain field to specialized extraction or human verification before continuing
- A vendor-by-dimension coverage matrix with explicit responsible work items
Explanation
Correct Answer
B:Different task classes need different tools and review controls. Routing prevents an oversized universal process from executing irrelevant steps. Billing requests need account and invoice controls, technical issues need diagnostic evidence, and legal matters need scoped policy review. Request classification should select the appropriate bounded workflow and authorization.
Incorrect Answers
A:A single billing specialist lacks the task-specific evidence and workflow for technical or legal requests. Classification should select the appropriate delegated capability rather than discard the request's domain.
C:Dynamic workflows branch based on observed confidence and task characteristics. That addresses a different part of the system, not the requirement to choose a task-specific workflow branch.
D:A dependency matrix shows which jobs are independent, which share a common prerequisite and which cannot run safely until an earlier result has been validated. The proposed option cannot provide the specific “Classify the request and dispatch it into domain-specific workflow branches” behavior that the case requires. Billing requests need account and invoice controls, technical issues need diagnostic evidence, and legal matters need scoped policy review.
Question 132
A team launches an expensive expert agent for every simple metadata check. What is a better structure?
- Keep the small tightly coupled writing task within one agent
- Use explicit prompt chaining or a fixed workflow with stage-by-stage validation
- Track per-document work units and aggregate statuses at checkpoints
- Use a lightweight deterministic precheck and escalate only uncertain cases to specialists
Explanation
Correct Answer
D:Hierarchical decomposition can reserve expensive reasoning for cases that need it. A fixed full-agent chain wastes resources on trivial inputs. Run cheap deterministic metadata checks first, then use the specialist only when the input falls outside accepted bounds or requires reasoning. Validate the escalation conditions against representative uncertain cases.
Incorrect Answers
A:Decomposition introduces coordination and reconciliation costs. The decisive requirement here is to separate low-cost routine checks from complex analysis. A task should not be needlessly split across agents, but the actual inefficiency is running an expensive specialist for deterministic metadata checks. A cheap first-stage filter provides the needed selection.
B:Chaining every metadata check through multiple model stages may add cost when a simple deterministic precheck would suffice. Route only ambiguous or failed cases to the expensive expert agent; do not make every straightforward field check incur specialist-model overhead.
C:Fine-grained progress accounting exposes stalls and supports partial retries. This alternative does not establish how to separate low-cost routine checks from complex analysis in the stated workflow.
Question 133
A product-launch coordinator has twelve separate checks, but only two are release-blocking and a fixed deadline is approaching. Which scheduling policy best protects the decision?
- Complete all easy, nonblocking checks first solely to maximize the number of green status indicators
- Identify the critical release prerequisites, assign their owners and deadlines, and run independent nonblocking checks concurrently without bypassing the critical gates
- Execute every check alphabetically without accounting for time, failure impact or dependencies
- Approve the release after whichever specialist finishes first and carry the remaining checks as undocumented assumptions
Explanation
Correct Answer
B:The coordinator should identify the two must-pass release checks and schedule their upstream evidence collection early enough to meet the deadline. Independent lower-risk checks can run in parallel within available capacity, but none should override a missing critical approval. Document owners, prerequisites, completion evidence and the fallback if a blocking check misses its deadline.
Incorrect Answers
A:Finishing low-impact checks first can produce an impressive completion count while the two conditions that actually block release remain unresolved. A release decision needs evidence on critical prerequisites before its deadline. Rank tasks by dependency and consequence, not by which progress bars are easiest to turn green.
C:Alphabetical scheduling ignores the checks’ different consequences and prerequisite relationships. A critical test may require upstream data and more time than an easy documentation step. Ordering solely by name can leave that test until too late; critical-path planning and bounded parallelism are more appropriate.
D:One completed check cannot certify the other eleven. Treating the first successful result as release approval conceals unverified blockers and can expose customers to an untested change. Preserve incomplete statuses and require both named release-blocking gates before any release action.
Question 134
A developer asks the model to implement and test ten changes in one opaque step. Which execution plan best fits these dependencies?
- Prefer one coordinated sequential workflow over many parallel subagents
- Serialize conflicting writes or assign distinct ownership boundaries
- Split work into independently verifiable edits with tests after each coherent change
- Let the model declare all ten changes tested without producing diffs or test results.
Explanation
Correct Answer
C:A developer asks the model to implement and test ten changes in one opaque step. The relevant control is to split work into independently verifiable edits with tests after each coherent change. Smaller validated units localize defects and make rollback and diagnosis easier. Represent dependencies and acceptance checks explicitly so a failed part does not silently contaminate later work.
Incorrect Answers
A:Serial dependencies prevent useful concurrency, and agent overhead would outweigh isolation benefits. Here, a developer asks the model to implement and test ten changes in one opaque step. Split work into independently verifiable edits with tests after each coherent change. Smaller validated units localize defects and make rollback and diagnosis easier.
B:Decomposition must account for shared resources to prevent lost updates and merge conflicts. Here, a developer asks the model to implement and test ten changes in one opaque step. Split work into independently verifiable edits with tests after each coherent change. Smaller validated units localize defects and make rollback and diagnosis easier.
D:A declaration of success is not test evidence. Without independently inspectable diffs and results, a ten-change batch can hide regressions or unimplemented requirements. The safer plan divides work into coherent testable changes, checking each before integration.
Question 135
A task is short and every step uses the previous step's output. Which task-decomposition change is most appropriate?
- Serialize conflicting writes or assign distinct ownership boundaries
- Assign explicit artifacts and acceptance checks to the three distinct task types
- Centralize the evidence ledger and reuse validated results across dependent tasks
- Prefer one coordinated sequential workflow over many parallel subagents
Explanation
Correct Answer
D:The relevant control is to prefer one coordinated sequential workflow over many parallel subagents. Serial dependencies prevent useful concurrency, and agent overhead would outweigh isolation benefits. This matters when a task is short and every step uses the previous step's output. Parallelize only tasks whose inputs are independent; serialize writes that share mutable state.
Incorrect Answers
A:Decomposition must account for shared resources to prevent lost updates and merge conflicts. Here, a task is short and every step uses the previous step's output. Prefer one coordinated sequential workflow over many parallel subagents. Serial dependencies prevent useful concurrency, and agent overhead would outweigh isolation benefits.
B:Well-defined handoffs preserve correctness across activities requiring different tools and evaluation criteria. Here, a task is short and every step uses the previous step's output. Prefer one coordinated sequential workflow over many parallel subagents. Serial dependencies prevent useful concurrency, and agent overhead would outweigh isolation benefits.
C:A shared provenance store reduces redundant work without sharing every specialist's scratch context. The proposed option cannot provide the specific “Prefer one coordinated sequential workflow over many parallel subagents” behavior that the case requires. Serial dependencies prevent useful concurrency, and agent overhead would outweigh isolation benefits.
Question 136
Four specialists independently analyze the same costly regulatory-document collection. Each currently downloads the identical, unchanged corpus before reasoning. Which delegation design avoids duplicate retrieval while preserving separate specialist judgments?
- Retrieve one authorized, versioned evidence snapshot and pass stable, relevant source handles to each separately scoped analysis task
- Have every specialist produce conclusions from memory so none of them needs to inspect the documents
- Give all specialists a single writable shared notebook and let whichever finishes last replace the others’ findings
- Fetch the documents four times and describe the duplicate downloads as independent confirming sources
Explanation
Correct Answer
A:The coordinator can fetch the authorized corpus once, record its document versions and access scope, and distribute the same immutable evidence references to specialist agents. The agents then analyze independently without multiplying identical network work or silently confusing different source versions. Distinct judgments do not require redundant downloads; the coordinator still verifies citations and resolves disagreement.
Incorrect Answers
B:Independent judgment requires access to the actual supporting documents, not merely recalling potentially stale details. Omitting source reads would make policy quotations unauditable. Share the verified evidence snapshot instead so each analyst can inspect the relevant sections and substantiate its own conclusions.
C:One shared mutable notebook can cause one specialist to erase or contaminate another’s analysis and makes it hard to attribute claims. The optimization here concerns duplicate retrieval of an unchanged corpus. Keep separate analysis contexts and a coordinator-owned synthesis while sharing read-only evidence handles.
D:Four copies of the same underlying regulatory documents do not count as four independent sources. Repeated retrieval increases latency and may even yield incompatible versions when the documents change. Reuse a documented authoritative snapshot, and treat genuine source independence as a question of provenance rather than download count.
Question 137
A request combines source collection, numerical analysis and final explanation. Which execution plan best fits these dependencies?
- Centralize the evidence ledger and reuse validated results across dependent tasks
- Assign explicit artifacts and acceptance checks to the three distinct task types
- Consolidate tightly coupled operations and delegate only meaningful independent work
- Begin numerical analysis and draft the final conclusion before the source-collection stage has returned verified inputs, so each workstream can run independently
Explanation
Correct Answer
B:When a request combines source collection, numerical analysis and final explanation, the system should assign explicit artifacts and acceptance checks to the three distinct task types. Well-defined handoffs preserve correctness across activities requiring different tools and evaluation criteria. Parallelize only tasks whose inputs are independent; serialize writes that share mutable state.
Incorrect Answers
A:A shared provenance store reduces redundant work without sharing every specialist's scratch context. The direct remedy is “Assign explicit artifacts and acceptance checks to the three distinct task types”, which the alternative does not itself accomplish. Well-defined handoffs preserve correctness across activities requiring different tools and evaluation criteria.
C:Too-fine fragmentation increases coordination cost and may reduce reliability instead of improving it. This is not a substitute for “Assign explicit artifacts and acceptance checks to the three distinct task types”; that control is necessary in the stated circumstances. Well-defined handoffs preserve correctness across activities requiring different tools and evaluation criteria.
D:Numerical analysis cannot use a dataset that the source-collection step has not produced or validated, and drafting the conclusion at the same time risks inventing values. The work can be decomposed into explicit evidence, calculation and explanation artifacts with clear acceptance checks, but dependent work must wait for its verified prerequisite.
Question 138
A multi-agent report repeatedly redoes searches another agent has already completed. Which task-decomposition change is most appropriate?
- Consolidate tightly coupled operations and delegate only meaningful independent work
- Parallelize independent evidence gathering, then sequence final synthesis after both finish
- Centralize the evidence ledger and reuse validated results across dependent tasks
- Split work into independently verifiable edits with tests after each coherent change
Explanation
Correct Answer
C:A multi-agent report repeatedly redoes searches another agent has already completed. The relevant control is to centralize the evidence ledger and reuse validated results across dependent tasks. A shared provenance store reduces redundant work without sharing every specialist's scratch context. Represent dependencies and acceptance checks explicitly so a failed part does not silently contaminate later work.
Incorrect Answers
A:Too-fine fragmentation increases coordination cost and may reduce reliability instead of improving it. Here, a multi-agent report repeatedly redoes searches another agent has already completed. Centralize the evidence ledger and reuse validated results across dependent tasks. A shared provenance store reduces redundant work without sharing every specialist's scratch context.
B:Decomposition should follow real data dependencies, not arbitrary paragraph boundaries. The direct remedy is “Centralize the evidence ledger and reuse validated results across dependent tasks”, which the alternative does not itself accomplish. A shared provenance store reduces redundant work without sharing every specialist's scratch context.
D:Smaller validated units localize defects and make rollback and diagnosis easier. Here, a multi-agent report repeatedly redoes searches another agent has already completed. Centralize the evidence ledger and reuse validated results across dependent tasks. A shared provenance store reduces redundant work without sharing every specialist's scratch context.
Question 139
A decomposition strategy creates dozens of trivial specialist tasks. How should the work be divided and coordinated?
- Parallelize independent evidence gathering, then sequence final synthesis after both finish
- Split work into independently verifiable edits with tests after each coherent change
- Prefer one coordinated sequential workflow over many parallel subagents
- Consolidate tightly coupled operations and delegate only meaningful independent work
Explanation
Correct Answer
D:The relevant control is to consolidate tightly coupled operations and delegate only meaningful independent work. Too-fine fragmentation increases coordination cost and may reduce reliability instead of improving it. This matters when a decomposition strategy creates dozens of trivial specialist tasks. Parallelize only tasks whose inputs are independent; serialize writes that share mutable state.

Question 140
An investigator wants to resume an earlier named code audit without reconstructing its context manually. What approach fits?
- Apply data-retention and deletion rules to stored sessions and attached artifacts
- Fork from a common checkpoint and modify prompts in separate branches
- Resume the saved named session instead of starting an unrelated conversation
- Persist concise evidence summaries and checkpoints before resuming or branching
Explanation
Correct Answer
C:A session identifier locates the intended execution history. Resumption reuses the appropriate prior context and avoids repeating completed investigative work. Use the recorded session identifier to retrieve the prior code-audit state and verify that its repository revision still applies. Starting a new unrelated session would lose the audit findings and unresolved items.
Incorrect Answers
A:Deleting the visible chat does not necessarily delete persisted session transcripts, attachments, cached tool outputs or saved subagent artifacts. This is not a substitute for “Resume the saved named session instead of starting an unrelated conversation”; that control is necessary in the stated circumstances. Use the recorded session identifier to retrieve the prior code-audit state and verify that its repository revision still applies.
B:Forking from a common checkpoint is appropriate for comparing alternative prompt strategies, but the investigator wants to continue one existing named code audit. Use its persisted session identity and context rather than creating separate divergent branches with new histories.
D:A named session is not unlimited memory. The scenario instead requires a way to resume the intended persisted session. Checkpoints support reliable resumption, but they do not select the specific earlier named audit session by themselves. The explicit session identifier determines which preserved audit history should be loaded.
