Question 340

A maintainer using GitHub Copilot finds, the following condition is confirmed: A custom prompt file does not appear in the IDE's picker. Which approach is the most defensible?

  1. Replace credentials with placeholders and specify safe input variables
  2. Run the tests with CI or a command rather than treating instructions as execution
  3. Add file-path-specific instructions for migration files
  4. Verify filename, directory and IDE feature support

Explanation

Correct Answer

D:

Select the action "Verify filename, directory and IDE feature support". Prompt file discovery depends on supported formats and locations. It is the specific match for the scenario in which A custom prompt file does not appear in the IDE's picker.

Incorrect Answers

A:

For the different scenario A migration prompt file contains sensitive production credentials copied from a draft, "Replace credentials with placeholders and specify safe input variables" could be appropriate. Reusable prompts can otherwise disclose the same secret on every invocation. The present requirement is A custom prompt file does not appear in the IDE's picker, which calls for "Verify filename, directory and IDE feature support". Prompt file discovery depends on supported formats and locations.

B:

"Run the tests with CI or a command rather than treating instructions as execution" targets An engineer expects a Copilot instructions file to execute the repository test suite automatically. Instruction files guide response generation but cannot attest to real test results. That differs from A custom prompt file does not appear in the IDE's picker; the required decision here is "Verify filename, directory and IDE feature support". Prompt file discovery depends on supported formats and locations.

C:

The action "Add file-path-specific instructions for migration files" is useful when Only migration scripts need an extra database rollback requirement. Scoped instructions avoid burdening unrelated code. Under the stated condition A custom prompt file does not appear in the IDE's picker, instead choose "Verify filename, directory and IDE feature support". Prompt file discovery depends on supported formats and locations.

Question 341

During an AI-assisted software release, the following condition is confirmed: A request to optimize sorting never states whether the input order for ties must be stable. Which recommendation correctly handles the situation?

  1. State the timezone and daylight-saving expectations
  2. Provide the approved retention policy and cite its owner
  3. Define accounting rules before requesting the calculation
  4. Specify stable ordering as a required invariant

Explanation

Correct Answer

D:

The choice "Specify stable ordering as a required invariant" matches the requirement: A request to optimize sorting never states whether the input order for ties must be stable. Missing invariants permit unwanted behavior changes. This is the best-supported approach under the stated constraint.

Incorrect Answers

A:

The action "State the timezone and daylight-saving expectations" is useful when An agent wants to resolve a timezone-dependent bug. Temporal correctness depends on specific timezone assumptions. Under the stated condition A request to optimize sorting never states whether the input order for ties must be stable, instead choose "Specify stable ordering as a required invariant". Missing invariants permit unwanted behavior changes.

B:

The alternative "Provide the approved retention policy and cite its owner" fits another situation: A repository change depends on a regulatory retention period not in the prompt. AI should not invent legal obligations or business deadlines. Here the condition is A request to optimize sorting never states whether the input order for ties must be stable; use "Specify stable ordering as a required invariant" instead. Missing invariants permit unwanted behavior changes.

C:

The alternative "Define accounting rules before requesting the calculation" addresses A prompt asks to calculate revenue but does not define refunds and tax handling. Business semantics cannot safely be inferred from column names. It does not resolve A request to optimize sorting never states whether the input order for ties must be stable; the correct choice is "Specify stable ordering as a required invariant". Missing invariants permit unwanted behavior changes.

Question 342

A maintainer using GitHub Copilot finds, the following condition is confirmed: An assistant generates English-only validation when customers use non-Latin names. Which action addresses the actual technical requirement?

  1. Provide the approved retention policy and cite its owner
  2. Specify stable ordering as a required invariant
  3. State the timezone and daylight-saving expectations
  4. State internationalization and locale constraints

Explanation

Correct Answer

D:

The best response is "State internationalization and locale constraints". Default examples can omit diverse user data. This directly addresses the condition: An assistant generates English-only validation when customers use non-Latin names.

Incorrect Answers

A:

The alternative "Provide the approved retention policy and cite its owner" fits another situation: A repository change depends on a regulatory retention period not in the prompt.

C:

For the different scenario An agent wants to resolve a timezone-dependent bug, "State the timezone and daylight-saving expectations" could be appropriate. Temporal correctness depends on specific timezone assumptions. The present requirement is An assistant generates English-only validation when customers use non-Latin names, which calls for "State internationalization and locale constraints". Default examples can omit diverse user data.

Question 343

While investigating a coding workflow, the following condition is confirmed: A prompt asks to calculate revenue but does not define refunds and tax handling. What is the best next step under this constraint?

  1. Specify stable ordering as a required invariant
  2. State internationalization and locale constraints
  3. Provide the approved retention policy and cite its owner
  4. Define accounting rules before requesting the calculation

Explanation

Correct Answer

D:

The appropriate action is "Define accounting rules before requesting the calculation". Business semantics cannot safely be inferred from column names. The decisive condition is A prompt asks to calculate revenue but does not define refunds and tax handling.

Question 345

An engineering lead documents, the following condition is confirmed: A repository change depends on a regulatory retention period not in the prompt. What should the team do first?

  1. State the timezone and daylight-saving expectations
  2. State internationalization and locale constraints
  3. Define accounting rules before requesting the calculation
  4. Provide the approved retention policy and cite its owner

Explanation

Correct Answer

D:

Given that A repository change depends on a regulatory retention period not in the prompt, choose "Provide the approved retention policy and cite its owner". AI should not invent legal obligations or business deadlines. This targets the identified problem rather than a neighboring issue.

Question 346

In a secure development review, the following condition is confirmed: A new implementation question receives references to an unrelated earlier incident. Which action addresses the actual technical requirement?

  1. Refer explicitly to the previous response and failed test
  2. Reduce the history to the representative failure and reproducer
  3. Provide an explicit short handoff with original references
  4. Start a fresh task-focused conversation or remove irrelevant history

Explanation

Correct Answer

D:

The best response is "Start a fresh task-focused conversation or remove irrelevant history". Stale dialogue can bias a new response. This directly addresses the condition: A new implementation question receives references to an unrelated earlier incident.

Incorrect Answers

A:

The alternative "Refer explicitly to the previous response and failed test" fits another situation: A developer wants a follow-up fix to a specific prior suggestion. Relevant history supports targeted iteration. Here the condition is A new implementation question receives references to an unrelated earlier incident; use "Start a fresh task-focused conversation or remove irrelevant history" instead. Stale dialogue can bias a new response.

B:

The alternative "Reduce the history to the representative failure and reproducer" addresses A prompt includes fifty unrelated compiler logs. Noise competes with relevant evidence for context. It does not resolve A new implementation question receives references to an unrelated earlier incident; the correct choice is "Start a fresh task-focused conversation or remove irrelevant history". Stale dialogue can bias a new response.

C:

For the different scenario A team wants to reuse an approved decision in another session, "Provide an explicit short handoff with original references" could be appropriate. Cross-session continuity needs grounded transfer rather than assumptions. The present requirement is A new implementation question receives references to an unrelated earlier incident, which calls for "Start a fresh task-focused conversation or remove irrelevant history". Stale dialogue can bias a new response.

Question 347

An engineering lead documents, the following condition is confirmed: A developer wants a follow-up fix to a specific prior suggestion. What is the best next step under this constraint?

  1. Reintroduce a concise controlling constraint and source
  2. Provide an explicit short handoff with original references
  3. Start a fresh task-focused conversation or remove irrelevant history
  4. Refer explicitly to the previous response and failed test

Explanation

Correct Answer

D:

The appropriate action is "Refer explicitly to the previous response and failed test". Relevant history supports targeted iteration. The decisive condition is A developer wants a follow-up fix to a specific prior suggestion.

Incorrect Answers

A:

The alternative "Reintroduce a concise controlling constraint and source" addresses A long session repeatedly forgets a documented compatibility rule. Context limits can cause older instructions to be omitted. It does not resolve A developer wants a follow-up fix to a specific prior suggestion; the correct choice is "Refer explicitly to the previous response and failed test". Relevant history supports targeted iteration.
