Anthropic CCA-F Practice Test 9

Question 80

A legacy repository has unknown test gaps and scattered modules. A team asks Claude to improve meaningful coverage, but cannot enumerate cases yet. Which first approach is appropriate?

  1. Regenerate all existing tests from the new prompt before checking whether they already cover the required behaviors.
  2. Use a fixed checklist unrelated to the codebase's architecture.
  3. Map relevant code and existing tests, then adaptively prioritize uncovered behaviors based on observed gaps.
  4. Generate 400 tests from filename patterns without reading source.

Explanation

Correct Answer

C:

Discovery is needed before determining which test cases provide the most value.

Incorrect Answers

A:

Replacing validated tests sacrifices coverage and reproducibility. An inventory of existing tests should guide only necessary additions.

B:

Unknown dependencies make an arbitrary plan incomplete.

D:

File names do not reveal real execution paths or existing coverage.

Question 81

A code reviewer must inspect twelve independent service files and later assess their shared API contract. What execution shape balances speed and completeness?

  1. Review independent files in parallel, then perform a deliberate integration pass over shared contracts.
  2. Review only the first three files and infer the rest by similarity.
  3. Run integration analysis before the individual files have been examined.
  4. Have every reviewer edit the shared API contract concurrently.

Explanation

Correct Answer

A:

Per-file work can run concurrently while interactions require a common synthesis.

Incorrect Answers

B:

Similarity is not evidence that all files are correct.

C:

The integration stage lacks needed module-level findings.

D:

Competing writes make the final interface unpredictable.

Question 82

During incident analysis, an unfamiliar cache invalidation dependency appears after the initial plan was approved. How should the coordinator respond?

  1. Mark the incident resolved because discovering a dependency is progress.
  2. Continue the original steps without considering the new cache finding.
  3. Revise remaining work to investigate the discovered dependency, retaining already verified findings.
  4. Discard the entire investigation and restart all completed checks from scratch.

Explanation

Correct Answer

C:

Adaptive decomposition accommodates evidence that was not available at planning time.

Incorrect Answers

A:

A hypothesis is not evidence of a repaired system.

B:

Ignoring an identified dependency can leave the incident unresolved.

D:

New information requires targeted work, not automatic repetition of sound steps.

Question 83

A data pipeline has fixed parse, schema-check and persistence stages, each with unambiguous inputs. Select TWO design decisions that fit this predictable transformation.

  1. Use a deterministic chain with explicit error handling at each stage rather than autonomous agents for each trivial operation.
  2. Persist records before validation to reduce latency.
  3. Launch independent planning agents that rewrite the schema on every record.
  4. Let the assistant choose whether to validate before or after persisting each record based on a confidence estimate.
  5. Validate each intermediate result against its declared contract before letting the following step persist state.

Explanation

Correct Answers

A:

Known transformations benefit from predictable validation and tracing.

E:

A deterministic chain is appropriate because its order is known. Explicit validation at transition boundaries prevents malformed parse output from silently reaching storage.

Incorrect Answers

B:

Invalid values could reach downstream systems.

C:

Dynamic changes undermine consistent typed output.

D:

The persistence prerequisite is a deterministic data-integrity invariant. Model confidence cannot substitute for required schema validation before state mutation.

Question 84

A single monorepo prompt to review 120 modules repeatedly misses cross-file dependencies. What would improve analysis?

  1. Partition module reviews by bounded area and synthesize a separate cross-module contract review.
  2. Review only the smallest module to represent all others.
  3. Increase prompt length indefinitely by concatenating every log.
  4. Let each worker make unsynchronized edits to shared files.

Explanation

Correct Answer

A:

Scoped inspection retains local detail while exposing integration risk at synthesis.

Incorrect Answers

B:

A sample cannot establish system-wide interaction correctness.

C:

Context pressure can further hide the relevant dependencies.

D:

Parallel uncoordinated mutation may introduce new cross-file defects.

Question 85

An open-ended research request starts with three broad themes; early evidence reveals an unanticipated regulatory requirement. What should drive the next delegation?

  1. Ignore the new requirement because it was absent from initial planning.
  2. Publish a definitive compliance conclusion from unrelated product notes.
  3. Restart every source search with the same queries to preserve uniformity.
  4. Have the coordinator select a targeted regulatory probe from the observed gap rather than freezing the original list.

Explanation

Correct Answer

D:

Discovery changes the needed evidence and should inform subsequent tasks.

Incorrect Answers

A:

Known missing coverage must not be hidden.

B:

The available notes cannot prove the regulatory requirement.

C:

Repetition does not fill a newly identified topic.

Question 86

A requested refactor touches authentication, billing, and one shared event contract. How should workstreams be decomposed?

  1. Allow independent agents to change the shared contract without version checks.
  2. Only test authentication because it is the first service listed.
  3. Treat every source file as independent regardless of runtime dependencies.
  4. Separate bounded risk domains, coordinate the shared contract and verify integration before merging changes.

Explanation

Correct Answer

D:

Distinct ownership and contract tests control high-impact interactions.

Incorrect Answers

A:

Concurrent uncontrolled mutation can break consumers.

B:

Billing and cross-boundary behavior remain unverified.

C:

File boundaries do not eliminate shared behavior.

Question 87

A CI generator must discover existing test suites, add missing cases, execute them, then inspect failures. The stages depend on prior outputs. Which design fits?

  1. Run the final failure analysis before executing any test.
  2. Have all three steps mutate the same test files in parallel.
  3. Implement an explicit discovery-to-generation-to-execution chain with failure feedback and bounded repair.
  4. Generate tests blindly before inspecting existing fixtures.

Explanation

Correct Answer

C:

Each downstream operation requires verified evidence from its predecessor.

Incorrect Answers

A:

No execution evidence exists to analyze.

B:

Dependent writes and reads can race and corrupt coverage.

D:

This risks duplicate or irrelevant cases.

Question 88

Midway through a staged migration, the requirements document is amended to keep an older API available longer. What should the agent change?

  1. Update only remaining dependent tasks and compatibility checks while retaining still-valid completed work.
  2. Reapply every earlier migration step even if its inputs did not change.
  3. Delete the history of approved steps to make replanning easier.
  4. Ignore the revised compatibility requirement until production errors appear.

Explanation

Correct Answer

A:

A scoped plan adjustment preserves verified progress and addresses the changed contract.

Incorrect Answers

B:

Routine repetition increases risk without resolving the new requirement.

C:

Without prior state the coordinator may repeat unsafe operations.

D:

The new condition is an explicit acceptance constraint.

Question 89

A team requests analysis of a 300-file refactor with unknown dependencies. A developer suggests editing from the first filename onward. What should happen first?

  1. Use only compilation as evidence that the proposed architecture is safe.
  2. Begin with the lexically first modified file and defer dependency inventory until after the changes are drafted.
  3. Edit all files in alphabetical order before mapping imports.
  4. Inventory modules and their call relationships, prioritize risky boundaries, then plan scoped changes.

Explanation

Correct Answer

D:

Dependency-aware discovery reduces the chance of breaking hidden consumers.

Incorrect Answers

A:

Compilation cannot reveal all behavioral or migration incompatibilities.

B:

Filename order is unrelated to architectural impact. High-risk shared interfaces may be discovered too late for safe planning.

C:

Name order bears no relationship to dependency or risk.

Question 90

A document-processing service receives 200 independent PDF batches that must later be joined by customer ID. How should the initial processing run?

  1. Extract batches concurrently under stable customer keys, then perform a controlled join and consistency check.
  2. Run one giant extraction prompt for every PDF simultaneously.
  3. Append all records in arrival order and assume they align by position.
  4. Discard source IDs after extraction because the join can infer them.

Explanation

Correct Answer

A:

Independent extraction can be parallel while reconciliation requires preserved identity.

Incorrect Answers

B:

Large unbounded context reduces traceability and may exceed limits.

C:

Concurrency means output order is not a reliable identity key.

D:

Missing identifiers make cross-batch reconciliation unreliable.
