GitHub Copilot GH-300 Practice Test 38

Question 370

Restate current requirements and use a fresh bounded context where necessary. The prior failure was: Chat history contains a failed migration that has since been rolled back. Which result is the most persuasive acceptance evidence?

  1. The resulting plan states which metric is improved and which invariants remain
  2. A compliance note reflects the correct plan's documented terms
  3. The agent keeps the required tests unchanged
  4. The next plan does not reference the abandoned migration

Explanation

Correct Answer

D:

The proposed result specifically establishes success rather than merely showing that a configuration exists. Earlier conversation can bias later suggestions toward obsolete assumptions. It is the observable consequence of the selected intervention.

Incorrect Answers

A:

This observation would make sense for the independent case "User intent encoding", whose acceptance criterion is The resulting plan states which metric is improved and which invariants remain. It is not proof of the current remediation. In this verification case, the decisive result is the next plan does not reference the abandoned migration, not a generic indication that the tool was used.

B:

This observation would make sense for the independent case "Data retention by plan", whose acceptance criterion is A compliance note reflects the correct plan's documented terms. It is not proof of the current remediation.

C:

This observation would make sense for the independent case "Prompt injection as data", whose acceptance criterion is The agent keeps the required tests unchanged. It is not proof of the current remediation.

Question 371

A code-generation workflow begins failing after a supported model is changed. What should the team implement or verify first?

  1. Run a regression suite and recalibrate prompts for the actual model
  2. Require code review and security testing after any model-side filter
  3. Treat the answer as probabilistic and validate against real APIs
  4. Avoid claiming a traceable training-source citation without a supported reference

Explanation

Correct Answer

A:

This intervention is proportionate to the problem. Models can differ in capability and output style. Its acceptance evidence is that a regression report identifies changes without relying on a fixed answer text.

Incorrect Answers

B:

This is a reasonable intervention for the separate case "Proxy filtering misconception". Its value is output filters cannot replace domain-specific secure design validation, not resolving the current requirement. Here the controlling problem is a code-generation workflow begins failing after a supported model is changed, and the proposal must meet that constraint.

C:

This is a reasonable intervention for the separate case "Language model limits". Its value is lLMs predict plausible tokens without guaranteed external execution, not resolving the current requirement.

D:

This is a reasonable intervention for the separate case "Model source uncertainty". Its value is generation does not inherently expose a deterministic training provenance, not resolving the current requirement.

Question 372

Refine descriptive names and assert behavior rather than tautologies. The prior failure was: A generated test has unclear names and assertions that always pass. Which outcome demonstrates that the original issue is resolved?

  1. Boundary values fail before the fix and pass afterward
  2. The test fails when the target behavior is intentionally broken
  3. All callers pass with consistent timezone and invalid-input behavior
  4. The fixture contains no real customer data and parser tests pass

Explanation

Correct Answer

B:

This observation is the required outcome: The test fails when the target behavior is intentionally broken. It tests the original requirement because test intent must be inspectable by future maintainers.

Incorrect Answers

A:

This result would validate a different action: Ask Copilot to suggest table-driven tests from a separate requirement. It applies when an existing function has no tests for negative balance handling, not to the failure being reviewed here.

C:

This result would validate a different action: Ask Copilot for a minimal shared helper while preserving behavior and run regression tests. It applies when a service repeats the same date parser in four modules, not to the failure being reviewed here. In this verification case, the decisive result is the test fails when the target behavior is intentionally broken, not a generic indication that the tool was used.

D:

This result would validate a different action: Generate obviously synthetic fixtures covering valid formats and rejects. It applies when a team needs synthetic address data to test a parser without copying customer records, not to the failure being reviewed here.

Question 373

Require code review and security testing after any model-side filter. The prior failure was: A team claims content safety filtering makes generated code production secure. What would make this decision ready for approval?

  1. A blocked example is not inserted and a permitted one is still reviewed
  2. A vulnerability test detects a flawed generated authorization branch
  3. The merge record shows authorized approvals and quality checks
  4. A lower-privileged test proves the bypass is rejected

Explanation

Correct Answer

B:

The proposed result specifically establishes success rather than merely showing that a configuration exists. Output filters cannot replace domain-specific secure design validation. It is the observable consequence of the selected intervention.

Incorrect Answers

A:

Safety filtering and user acceptance are distinct stages. That result is therefore evidence for a different capability, while this review requires a vulnerability test detects a flawed generated authorization branch.

C:

Generated contributions remain code changes requiring human decisions. That result is therefore evidence for a different capability, while this review requires a vulnerability test detects a flawed generated authorization branch.

D:

Safety filters cannot enforce every application-specific invariant. That result is therefore evidence for a different capability, while this review requires a vulnerability test detects a flawed generated authorization branch.

Question 374

A product manager needs a quick functional prototype from a clear feature description. What is the defensible engineering decision?

  1. Use a Copilot PR summary as a draft and verify significant touched components
  2. Use Copilot code review as assistance and perform normal human code review
  3. Use GitHub Spark where available and review the generated app before deployment
  4. Inspect the diff and run project tests before accepting the edit

Explanation

Correct Answer

C:

This intervention is proportionate to the problem. Spark supports app prototyping but generated apps still need security checks. Its acceptance evidence is that the prototype demonstrates the requested flow without production credentials.

Incorrect Answers

A:

Although technically useful, this addresses a release manager needs a readable overview of the changes in a large PR. The stated constraint instead needs a change whose evidence is: The prototype demonstrates the requested flow without production credentials.

B:

Although technically useful, this addresses an external contributor's pull request changes authorization code and has an AI-generated summary. The stated constraint instead needs a change whose evidence is: The prototype demonstrates the requested flow without production credentials.

D:

Although technically useful, this addresses an agent has edited a service and then declares the task complete. The stated constraint instead needs a change whose evidence is: The prototype demonstrates the requested flow without production credentials.

Question 375

Document current preview status and add compensating safeguards. The prior failure was: A privacy policy treats a preview exclusion feature as a permanent organization guarantee. What result validates both behavior and scope?

  1. The governance record names the limitation and review cadence
  2. The report identifies change actor and effective setting
  3. Matching suggestions follow the organization policy
  4. A known matching pattern is blocked where the feature supports it

Explanation

Correct Answer

A:

This observation is the required outcome: The governance record names the limitation and review cadence. It tests the original requirement because preview functionality and support boundaries can evolve.

Incorrect Answers

B:

Unlike the requested acceptance outcome, this observation checks a separate situation: an administrator must prove who changed a Copilot organization policy. It cannot confirm the specified intervention by itself.

C:

Unlike the requested acceptance outcome, this observation checks a separate situation: a user disables code-matching policy in their settings but enterprise blocks matches. It cannot confirm the specified intervention by itself. In this verification case, the decisive result is the governance record names the limitation and review cadence, not a generic indication that the tool was used.

D:

Unlike the requested acceptance outcome, this observation checks a separate situation: an organization prohibits matching public-code suggestions in supported products. It cannot confirm the specified intervention by itself.

Question 376

Copilot suggests piping an unverified script from the internet directly into a privileged shell. What choice best matches the actual acceptance criteria?

  1. Compare the design against hosting constraints before implementing
  2. Restrict the target path, dry-run, and obtain review before executing destructive commands
  3. Inspect and verify the script source before running with least privilege
  4. Use parameterized queries and test malicious input

Explanation

Correct Answer

C:

The key is the specific capability, not simply the fact that AI suggested it. Generated commands can perform actions outside the intended scope. In this case the proposed action is inspect and verify the script source before running with least privilege; confirm it through the concrete expected result.

Incorrect Answers

A:

This measure fits a different failure: copilot proposes serverless for a long-running stateful task with strict socket requirements. In that situation suggestions predict likely patterns but do not verify service limits. It does not establish the requested outcome: only audited actions run under an account with limited permissions.

B:

This measure fits a different failure: copilot proposes a cleanup script that recursively removes a shared project directory. In that situation a natural-language assistant may infer a broader target than intended. It does not establish the requested outcome: only audited actions run under an account with limited permissions.

D:

This measure fits a different failure: copilot suggests interpolating a search term into a SQL string on an admin reporting page. In that situation parameter binding separates input data from SQL syntax. It does not establish the requested outcome: only audited actions run under an account with limited permissions.

Question 377

A new REST endpoint needs validation, error mapping and a test skeleton. Select the remediation supported by this evidence.

  1. Ask Copilot to suggest table-driven tests from a separate requirement
  2. Use Copilot to draft a docstring from source and tests, then correct it manually
  3. Ask Copilot for a minimal example and verify it in the vendor docs
  4. Use Copilot to draft boilerplate while specifying project conventions

Explanation

Correct Answer

D:

This intervention is proportionate to the problem. Automation saves repetitive typing, not domain-specific review. Its acceptance evidence is that the endpoint uses standard middleware and passes input validation tests.

Incorrect Answers

A:

Test generation helps coverage when expectations are independently specified. That makes this relevant when an existing function has no tests for negative balance handling, whereas this scenario has a different controlling requirement and acceptance test. Here the controlling problem is a new REST endpoint needs validation, error mapping and a test skeleton, and the proposal must meet that constraint.

B:

Generated documentation is a useful draft but may misstate contracts. That makes this relevant when a teammate inherits an undocumented function with surprising side effects, whereas this scenario has a different controlling requirement and acceptance test. Here the controlling problem is a new REST endpoint needs validation, error mapping and a test skeleton, and the proposal must meet that constraint.

C:

Examples can accelerate learning but may use outdated signatures. That makes this relevant when an engineer needs to use a new test assertion API but wants a safe learning example, whereas this scenario has a different controlling requirement and acceptance test. Here the controlling problem is a new REST endpoint needs validation, error mapping and a test skeleton, and the proposal must meet that constraint.

Question 378

Use path-specific .github/instructions/*.instructions.md where supported. The prior failure was: A monorepo's backend files require different conventions from frontend modules. Which result is the most persuasive acceptance evidence?

  1. Only files under the approved checkout are changed
  2. Only selected files receive the intended refactor
  3. Backend and frontend generated edits follow their respective conventions
  4. All three files form one coherent tested change without extra side effects

Explanation

Correct Answer

C:

This observation is the required outcome: Backend and frontend generated edits follow their respective conventions. It tests the original requirement because path-specific rules supply targeted context without cluttering all prompts.

Incorrect Answers

A:

This observation would make sense for the independent case "CLI workspace boundary", whose acceptance criterion is Only files under the approved checkout are changed. It is not proof of the current remediation.

B:

This observation would make sense for the independent case "Copilot Edits scope", whose acceptance criterion is Only selected files receive the intended refactor. It is not proof of the current remediation.

D:

This observation would make sense for the independent case "Agent mode task", whose acceptance criterion is All three files form one coherent tested change without extra side effects. It is not proof of the current remediation.

Question 379

An administrator must prove who changed a Copilot organization policy. Which course of action is best justified?

  1. Set the matching-code policy to Block in the correct organization settings
  2. Review audit logs and effective settings through authorized admin tools
  3. Identify the effective policy in the actual client and account
  4. Treat source content as untrusted and verify agent permissions

Explanation

Correct Answer

B:

The key is the specific capability, not simply the fact that AI suggested it. Policy configuration should leave a traceable audit trail where supported. In this case the proposed action is review audit logs and effective settings through authorized admin tools; confirm it through the concrete expected result.

Incorrect Answers

A:

This is a reasonable intervention for the separate case "Public code block". Its value is the filter can suppress detected matching suggestions but is not a complete legal guarantee, not resolving the current requirement.

C:

This is a reasonable intervention for the separate case "Settings specificity". Its value is admin controls can supersede personal choices and vary by surface, not resolving the current requirement. Here the controlling problem is an administrator must prove who changed a Copilot organization policy, and the proposal must meet that constraint.

D:

This is a reasonable intervention for the separate case "Malicious prompt text". Its value is prompt injection in files can try to evade safeguards, not resolving the current requirement. Here the controlling problem is an administrator must prove who changed a Copilot organization policy, and the proposal must meet that constraint.

Question 380

Exclude unsupported client together with Legal provenance now needs a coordinated review. The first finding is: A developer expects an exclusion rule to work identically across VS Code and web Copilot Chat. The second finding is: A suggestion appears identical to licensed code copied from a blog. Select TWO actions, one that resolves each finding.

  1. Disable or scope the MCP integration independently from the exclusion rule
  2. Explain how detected public-code matches may be suppressed
  3. Check the current support matrix for each client and mode
  4. Identify the effective policy in the actual client and account
  5. Use matching-code references where available and obtain licensing review

Explanation

Correct Answers

C:

This addresses the first finding. Exclusion coverage differs between products and may be preview-only. The verification is: Documented unsupported surfaces get separate compensating controls. The complementary action addresses Legal provenance.

E:

This addresses the second finding. Similarity detection is a clue, not a definitive origin or usage right. The verification is: The retained code has approved provenance or is replaced. The complementary action addresses Exclude unsupported client.

Incorrect Answers

A:

This is relevant to a different case: An excluded secret file is available to a third-party MCP tool. Its capability is: Third-party tool access is a separate trust boundary. Neither Exclude unsupported client nor Legal provenance requires that result.

B:

This is relevant to a different case: A developer complains that a very similar completion is missing under Block mode. Its capability is: Matching-code policy can prevent a suggestion from being presented. Neither Exclude unsupported client nor Legal provenance requires that result.

D:

This is relevant to a different case: A personal editor preference conflicts with an enterprise Copilot setting. Its capability is: Admin controls can supersede personal choices and vary by surface. Neither Exclude unsupported client nor Legal provenance requires that result.
