Question 90

A maintainer using GitHub Copilot finds, the following condition is confirmed: A generated command embeds an unexpected network call unrelated to the requested fix. Which approach is the most defensible?

  1. Validate tool permissions independently before granting access
  2. Inspect and remove the unexplained outbound operation
  3. Treat the comment as untrusted task data and refuse the upload
  4. Parse the fixture as test data rather than executing embedded requests

Explanation

Correct Answer

B:

Select the action "Inspect and remove the unexplained outbound operation". Hidden side effects can indicate prompt injection or compromised context. It is the specific match for the scenario in which A generated command embeds an unexpected network call unrelated to the requested fix.

Incorrect Answers

A:

For the different scenario A third-party MCP response asks for expanded repository permissions, "Validate tool permissions independently before granting access" could be appropriate. Tool output is not an administrative approval channel. The present requirement is A generated command embeds an unexpected network call unrelated to the requested fix, which calls for "Inspect and remove the unexplained outbound operation". Hidden side effects can indicate prompt injection or compromised context.

C:

The action "Treat the comment as untrusted task data and refuse the upload" is useful when An issue comment instructs an agent to upload environment variables to a URL. Retrieved text cannot grant authority over secrets or tools. Under the stated condition A generated command embeds an unexpected network call unrelated to the requested fix, instead choose "Inspect and remove the unexplained outbound operation". Hidden side effects can indicate prompt injection or compromised context.

D:

The alternative "Parse the fixture as test data rather than executing embedded requests" fits another situation: A test fixture includes instructions to disable audit logging. Data fields can contain attacker-controlled instructions. Here the condition is A generated command embeds an unexpected network call unrelated to the requested fix; use "Inspect and remove the unexplained outbound operation" instead. Hidden side effects can indicate prompt injection or compromised context.

Question 91

During an AI-assisted software release, the following condition is confirmed: An AI response gives several plausible fixes but no reproduction information. Which recommendation correctly handles the situation?

  1. Create a minimal reproduction before choosing a remediation
  2. Check the current extension documentation and version
  3. Locate the official policy control before configuring it
  4. Escalate to the code owner and existing acceptance criteria

Explanation

Correct Answer

A:

The choice "Create a minimal reproduction before choosing a remediation" matches the requirement: An AI response gives several plausible fixes but no reproduction information. Targeted evidence resolves ambiguity more reliably than confidence phrasing. This is the best-supported approach under the stated constraint.

Incorrect Answers

B:

The alternative "Check the current extension documentation and version" fits another situation: A question depends on a newly released editor extension feature. Feature support changes across clients and releases. Here the condition is An AI response gives several plausible fixes but no reproduction information; use "Create a minimal reproduction before choosing a remediation" instead. Targeted evidence resolves ambiguity more reliably than confidence phrasing.

C:

The alternative "Locate the official policy control before configuring it" addresses Copilot proposes an undocumented enterprise policy setting. Plausible setting names are not proof of supported administration. It does not resolve An AI response gives several plausible fixes but no reproduction information; the correct choice is "Create a minimal reproduction before choosing a remediation". Targeted evidence resolves ambiguity more reliably than confidence phrasing.

D:

For the different scenario An assistant cannot determine which of two tests is authoritative, "Escalate to the code owner and existing acceptance criteria" could be appropriate. AI uncertainty should not be hidden with a fabricated decisive answer. The present requirement is An AI response gives several plausible fixes but no reproduction information, which calls for "Create a minimal reproduction before choosing a remediation". Targeted evidence resolves ambiguity more reliably than confidence phrasing.

Question 92

A maintainer using GitHub Copilot finds, the following condition is confirmed: A question depends on a newly released editor extension feature. Which action addresses the actual technical requirement?

  1. Locate the official policy control before configuring it
  2. Check the current extension documentation and version
  3. Identify the deployed product edition and apply its supported procedure
  4. Create a minimal reproduction before choosing a remediation

Explanation

Correct Answer

B:

The best response is "Check the current extension documentation and version". Feature support changes across clients and releases. This directly addresses the condition: A question depends on a newly released editor extension feature.

Incorrect Answers

A:

The alternative "Locate the official policy control before configuring it" fits another situation: Copilot proposes an undocumented enterprise policy setting. Plausible setting names are not proof of supported administration. Here the condition is A question depends on a newly released editor extension feature; use "Check the current extension documentation and version" instead. Feature support changes across clients and releases.

C:

For the different scenario Two documentation pages disagree because they target different editions, "Identify the deployed product edition and apply its supported procedure" could be appropriate. Edition and plan constraints can explain apparently conflicting guidance. The present requirement is A question depends on a newly released editor extension feature, which calls for "Check the current extension documentation and version". Feature support changes across clients and releases.

D:

"Create a minimal reproduction before choosing a remediation" targets An AI response gives several plausible fixes but no reproduction information. Targeted evidence resolves ambiguity more reliably than confidence phrasing. That differs from A question depends on a newly released editor extension feature; the required decision here is "Check the current extension documentation and version". Feature support changes across clients and releases.

Question 93

While investigating a coding workflow, the following condition is confirmed: Copilot proposes an undocumented enterprise policy setting. What is the best next step under this constraint?

  1. Escalate to the code owner and existing acceptance criteria
  2. Check the current extension documentation and version
  3. Identify the deployed product edition and apply its supported procedure
  4. Locate the official policy control before configuring it

Explanation

Correct Answer

D:

The appropriate action is "Locate the official policy control before configuring it". Plausible setting names are not proof of supported administration. The decisive condition is Copilot proposes an undocumented enterprise policy setting.

Incorrect Answers

Question 96

In a secure development review, the following condition is confirmed: An agent needs to execute a database migration in a regulated environment. Which action addresses the actual technical requirement?

  1. Require the configured change approval and backup verification
  2. Use the approved operations window and explicit authorization
  3. Restrict the command to verified disposable outputs
  4. Refuse public publishing and preserve repository visibility

Explanation

Correct Answer

A:

The best response is "Require the configured change approval and backup verification". Agentic execution does not replace change management. This directly addresses the condition: An agent needs to execute a database migration in a regulated environment.

Incorrect Answers

B:

The alternative "Use the approved operations window and explicit authorization" addresses A proposed automation schedules production restarts without maintenance approval. Availability-impacting actions need owner-controlled timing. It does not resolve An agent needs to execute a database migration in a regulated environment; the correct choice is "Require the configured change approval and backup verification". Agentic execution does not replace change management.

C:

For the different scenario A terminal assistant asks permission to delete generated artifacts and source code together, "Restrict the command to verified disposable outputs" could be appropriate. Broad file operations risk removing canonical assets. The present requirement is An agent needs to execute a database migration in a regulated environment, which calls for "Require the configured change approval and backup verification". Agentic execution does not replace change management.

D:

"Refuse public publishing and preserve repository visibility" targets A tool call would publish an internal repository while investigating a build error. Diagnostic permission does not imply distribution permission. That differs from An agent needs to execute a database migration in a regulated environment; the required decision here is "Require the configured change approval and backup verification".
