Question 70

An audit of the proposed fix for Mariner Shipping requires a specific controlled check. The issue under review is: A travel operator must translate short customer requests among supported languages, but a text classifier is used to guess the meaning. Which independently observable result best verifies that the remediation works?

  1. Questions about changed policies return grounded citations from the current authorized version and unsupported claims are flagged.
  2. Bilingual reviewers confirm that representative messages preserve intent in the requested target languages.
  3. A representative load test meets the quality floor while p95 latency and per-request token spend fall within target.
  4. The selected model is cataloged with version, region, access controls, and a passing task-specific holdout result.

Explanation

Correct Answer

B:

Bilingual reviewers confirm that representative messages preserve intent in the requested target languages. This controlled observation specifically validates the proposed remedy: Use Cloud Translation API for translation with source/target language controls and task-appropriate quality review. It addresses the documented failure at Mariner Shipping: A travel operator must translate short customer requests among supported languages, but a text classifier is used to guess the meaning.

Incorrect Answers

A:

Questions about changed policies return grounded citations from the current authorized version and unsupported claims are flagged. This is evidence for a different corrective change: Use retrieval-augmented generation against versioned, access-controlled policy documents with source citations. That other change addresses: An enterprise assistant answers detailed policy questions without consulting its updated handbook and repeatedly invents clause wording. It does not validate the specific Mariner Shipping remediation for: A travel operator must translate short customer requests among supported languages, but a text classifier is used to guess the meaning. The necessary check instead is: Bilingual reviewers confirm that representative messages preserve intent in the requested target languages.

C:

A representative load test meets the quality floor while p95 latency and per-request token spend fall within target. This is evidence for a different corrective change: Benchmark smaller appropriate Gemini model variants and optimize routing by measured quality, latency, and token cost. That other change addresses: A live chat assistant uses the largest available Gemini model for every trivial classification request and exceeds its latency budget. It does not validate the specific Mariner Shipping remediation for: A travel operator must translate short customer requests among supported languages, but a text classifier is used to guess the meaning. The necessary check instead is: Bilingual reviewers confirm that representative messages preserve intent in the requested target languages.

D:

The selected model is cataloged with version, region, access controls, and a passing task-specific holdout result. This is evidence for a different corrective change: Select and evaluate a suitable model through Gemini Enterprise Agent Platform Model Garden with documented licensing and region availability. That other change addresses: A research team manually deploys an arbitrary publicly found checkpoint although it needs a supported managed foundational model with known versions and access terms. It does not validate the specific Mariner Shipping remediation for: A travel operator must translate short customer requests among supported languages, but a text classifier is used to guess the meaning. The necessary check instead is: Bilingual reviewers confirm that representative messages preserve intent in the requested target languages.

Question 71

Mercury Travel Tech has asked its ML engineering advisor to investigate a reported implementation fault within a travel technology workload: A travel operator must translate short customer requests among supported languages, but a text classifier is used to guess the meaning. Which engineering response addresses the immediate root problem most directly?

  1. Use retrieval-augmented generation against versioned, access-controlled policy documents with source citations.
  2. Treat retrieved content as untrusted data and enforce instruction hierarchy plus input/output safeguards.
  3. Use Cloud Translation API for translation with source/target language controls and task-appropriate quality review.
  4. Select and evaluate a suitable model through Gemini Enterprise Agent Platform Model Garden with documented licensing and region availability.

Explanation

Correct Answer

C:

Use Cloud Translation API for translation with source/target language controls and task-appropriate quality review. This directly targets the observed failure: A travel operator must translate short customer requests among supported languages, but a text classifier is used to guess the meaning. For the Mercury Travel Tech case, successful remediation should be demonstrated with this acceptance evidence: Bilingual reviewers confirm that representative messages preserve intent in the requested target languages.

Incorrect Answers

A:

Use retrieval-augmented generation against versioned, access-controlled policy documents with source citations.

The discriminating acceptance check here is: Bilingual reviewers confirm that representative messages preserve intent in the requested target languages.

B:

Treat retrieved content as untrusted data and enforce instruction hierarchy plus input/output safeguards. This action could be suitable for a different engineering incident: A customer-facing LLM assistant replies to malicious embedded instructions in retrieved articles that attempt to override system rules. It does not directly correct the reported Mercury Travel Tech failure: A travel operator must translate short customer requests among supported languages, but a text classifier is used to guess the meaning. The discriminating acceptance check here is: Bilingual reviewers confirm that representative messages preserve intent in the requested target languages.

D:

Question 73

Atlas Equipment has asked its ML engineering advisor to investigate a reported implementation fault within a equipment service workload: A knowledge team wants concise summaries of long service reports but chooses a conventional image classifier and receives no usable prose. Which change best resolves the documented failure without substituting an unrelated improvement?

  1. Use Cloud Translation API for translation with source/target language controls and task-appropriate quality review.
  2. Create a task-specific blind evaluation rubric covering correctness, safety, refusal behavior, latency, and cost before model selection.
  3. Use retrieval-augmented generation against versioned, access-controlled policy documents with source citations.
  4. Use an appropriate Gemini generative text model with controlled instructions and human-validated summarization criteria.

Explanation

Correct Answer

D:
