Question 380
A customer-facing medical information assistant may invent unsafe dosage recommendations. Which option BEST meets the business requirement?
- Increase completion length to improve medical authority
- Ground answers in approved references and require safety and clinical escalation rules
- Treat any confident generated dosage as approved clinical guidance
- Disable all source links and let the model reason unaudited
Explanation
Correct Answer
B:High-stakes unsupported medical claims need source checking and human control The specified scenario makes this the most appropriate approach.
Incorrect Answers
A:Longer advice is not clinical validation This prevents the approach from meeting the stated requirement.
C:Model confidence cannot establish medical safety This prevents the approach from meeting the stated requirement.
D:Removing provenance increases the chance of undetected errors This prevents the approach from meeting the stated requirement.
Question 381
An external chat assistant sometimes returns insulting or hateful language. During a design review, someone proposes Change IAM billing permissions to remove toxic language. Which technical objection is specifically relevant to this proposal?
- Guardrails can help filter unwanted model inputs and outputs
- Prompt wording alone is not a complete moderation control
- Retrieval search is not an output toxicity control
- Billing authorization does not inspect generated text
Explanation
Correct Answer
D:This is the actual failure mode of the proposed approach: Change IAM billing permissions to remove toxic language. Billing authorization does not inspect generated text
Incorrect Answers
A:Guardrails can help filter unwanted model inputs and outputs This explains the recommended design, but it is not the requested diagnosis of Change IAM billing permissions to remove toxic language.
B:This limitation concerns Rely only on a polite system persona without safety testing; it does not diagnose the proposed Change IAM billing permissions to remove toxic language approach.
C:This limitation concerns Use only a vector database index as the content safety filter; it does not diagnose the proposed Change IAM billing permissions to remove toxic language approach.
Question 382
A language model is being adapted for a multilingual community with underrepresented dialects. Before approving a rollout, an architect suggests Increase output tokens as the entire inclusion strategy. Which mismatch should be documented for this precise design?
- More generated words cannot add missing training representation
- Missing dialect examples can harm the omitted users
- A single dialect benchmark cannot prove broader coverage
- Inclusive datasets and subgroup testing help identify representation gaps
Explanation
Correct Answer
A:This is the actual failure mode of the proposed approach: Increase output tokens as the entire inclusion strategy. More generated words cannot add missing training representation
Incorrect Answers
B:This limitation concerns Train only on dominant dialect samples and assume transfer is perfect; it does not diagnose the proposed Increase output tokens as the entire inclusion strategy approach.
C:This limitation concerns Use only one high-performing standard-language benchmark; it does not diagnose the proposed Increase output tokens as the entire inclusion strategy approach.
D:Inclusive datasets and subgroup testing help identify representation gaps This explains the recommended design, but it is not the requested diagnosis of Increase output tokens as the entire inclusion strategy.
Question 383
A regulated firm must document a model's intended use, limitations and risk rating. Before approving a rollout, an architect suggests Treat a dataset location as the entire model documentation. Which mismatch should be documented for this precise design?
- A storage path cannot capture evaluation and intended use
- Model Cards capture model metadata, intended uses and risk considerations
- Cost reports omit intended uses and technical limitations
- Weights alone do not describe governance decisions
Explanation
Correct Answer
A:This is the actual failure mode of the proposed approach: Treat a dataset location as the entire model documentation. A storage path cannot capture evaluation and intended use
Incorrect Answers
B:Model Cards capture model metadata, intended uses and risk considerations This explains the recommended design, but it is not the requested diagnosis of Treat a dataset location as the entire model documentation.
C:This limitation concerns Use billing invoices as the complete model-risk record; it does not diagnose the proposed Treat a dataset location as the entire model documentation approach.
D:This limitation concerns Assume a saved model weight file documents model lineage and risk; it does not diagnose the proposed Treat a dataset location as the entire model documentation approach.

D:This limitation concerns Use only one high-performing standard-language benchmark; it does not diagnose the proposed Train only on dominant dialect samples and assume transfer is perfect approach.
Question 385
An AI assistant's refusals frustrate legitimate users while missing some unsafe requests. After selecting the recommended approach, which evidence MOST DIRECTLY demonstrates that the actual required outcome has been achieved?
- A system inventory lists this competing approach as active: Set all filters maximally restrictive without usability testing
- Reviewed safe and unsafe test sets show acceptable filtering performance
- A component test invokes this alternate approach successfully: Turn all safety filters off to eliminate refusals
- A reviewed design record approves this competing approach: Judge only the total number of blocked prompts
Explanation
Correct Answer
B:Reviewed safe and unsafe test sets show acceptable filtering performance. This checks the business result rather than just a configured feature.
Incorrect Answers
A:Overblocking can prevent legitimate business activity An active setting cannot independently prove the requested business outcome.
C:No filtering exposes users to prohibited content A component invocation does not validate the necessary end-to-end outcome.
D:Raw block count does not reveal missed harms or unjustified refusals Design approval is not evidence that the alternative meets the actual requirement.
Question 386
An AI assistant's refusals frustrate legitimate users while missing some unsafe requests. Before approving a rollout, an architect suggests Judge only the total number of blocked prompts. Which mismatch should be documented for this precise design?
- Raw block count does not reveal missed harms or unjustified refusals
- No filtering exposes users to prohibited content
- Overblocking can prevent legitimate business activity
- Safety requires balancing blocked harmful output with useful allowed output
Explanation
Correct Answer
A:This is the actual failure mode of the proposed approach: Judge only the total number of blocked prompts. Raw block count does not reveal missed harms or unjustified refusals
Incorrect Answers
B:This limitation concerns Turn all safety filters off to eliminate refusals; it does not diagnose the proposed Judge only the total number of blocked prompts approach.
C:This limitation concerns Set all filters maximally restrictive without usability testing; it does not diagnose the proposed Judge only the total number of blocked prompts approach.
D:Safety requires balancing blocked harmful output with useful allowed output This explains the recommended design, but it is not the requested diagnosis of Judge only the total number of blocked prompts.
