Microsoft GH-300 Practice Test 3

Question 20

A developer working in a governed organization reports, the following condition is confirmed: A generated file upload handler trusts extension alone and writes to a public directory. What should the team do first?

  1. Validate content and size, sanitize paths, and isolate uploads
  2. Preserve authorization and use isolated test identities instead
  3. Use safe argument passing and reject unexpected input
  4. Replace concatenation with parameterized SQL statements

Explanation

Correct Answer

A:

Given that A generated file upload handler trusts extension alone and writes to a public directory, choose "Validate content and size, sanitize paths, and isolate uploads". Filename metadata alone does not prevent malicious content or path traversal. This targets the identified problem rather than a neighboring issue.

Incorrect Answers

B:

The action "Preserve authorization and use isolated test identities instead" is useful when A suggested web endpoint disables authentication to simplify testing. Temporary authentication bypasses can become exploitable production paths. Under the stated condition A generated file upload handler trusts extension alone and writes to a public directory, instead choose "Validate content and size, sanitize paths, and isolate uploads". Filename metadata alone does not prevent malicious content or path traversal.

C:

The alternative "Use safe argument passing and reject unexpected input" fits another situation: A script executes a user-supplied shell argument through a command string. Shell interpolation can turn data into unintended commands. Here the condition is A generated file upload handler trusts extension alone and writes to a public directory; use "Validate content and size, sanitize paths, and isolate uploads" instead. Filename metadata alone does not prevent malicious content or path traversal.

D:

The alternative "Replace concatenation with parameterized SQL statements" addresses A generated SQL query concatenates an untrusted username into a string. Parameter binding separates untrusted values from SQL syntax. It does not resolve A generated file upload handler trusts extension alone and writes to a public directory; the correct choice is "Validate content and size, sanitize paths, and isolate uploads". Filename metadata alone does not prevent malicious content or path traversal.

Question 21

While onboarding an engineering team, the following condition is confirmed: A generated function is nearly identical to a known third-party repository implementation. Which action addresses the actual technical requirement?

  1. Compare the public-code reference and review its license obligations
  2. Keep human-reviewed commits and appropriate provenance records
  3. Preserve relevant attribution and consult the license before integrating
  4. Design an original solution from requirements without copying protected source

Explanation

Correct Answer

A:

The best response is "Compare the public-code reference and review its license obligations". Similarity requires a provenance and licensing decision before reuse. This directly addresses the condition: A generated function is nearly identical to a known third-party repository implementation.

Incorrect Answers

B:

The alternative "Keep human-reviewed commits and appropriate provenance records" addresses A release audit cannot trace which AI-generated changes were accepted. Traceability supports review and remediation of uncertain sources. It does not resolve A generated function is nearly identical to a known third-party repository implementation; the correct choice is "Compare the public-code reference and review its license obligations". Similarity requires a provenance and licensing decision before reuse.

C:

For the different scenario A suggested snippet includes a copyright notice from another project, "Preserve relevant attribution and consult the license before integrating" could be appropriate. Embedded notices can indicate externally sourced material with obligations. The present requirement is A generated function is nearly identical to a known third-party repository implementation, which calls for "Compare the public-code reference and review its license obligations". Similarity requires a provenance and licensing decision before reuse.

D:

"Design an original solution from requirements without copying protected source" targets A team asks Copilot to reproduce an entire paid library implementation. AI tools should not be used to bypass source licensing restrictions. That differs from A generated function is nearly identical to a known third-party repository implementation; the required decision here is "Compare the public-code reference and review its license obligations". Similarity requires a provenance and licensing decision before reuse.

Question 22

A developer working in a governed organization reports, the following condition is confirmed: A developer assumes all Copilot output automatically carries an unrestricted license. What is the best next step under this constraint?

  1. Apply organizational IP review rather than inventing an automatic license grant
  2. Compare the public-code reference and review its license obligations
  3. Design an original solution from requirements without copying protected source
  4. Keep human-reviewed commits and appropriate provenance records

Explanation

Correct Answer

A:

The appropriate action is "Apply organizational IP review rather than inventing an automatic license grant". Generation does not eliminate the need for rights and attribution analysis. The decisive condition is A developer assumes all Copilot output automatically carries an unrestricted license.

Incorrect Answers

B:

For the different scenario A generated function is nearly identical to a known third-party repository implementation, "Compare the public-code reference and review its license obligations" could be appropriate. Similarity requires a provenance and licensing decision before reuse. The present requirement is A developer assumes all Copilot output automatically carries an unrestricted license, which calls for "Apply organizational IP review rather than inventing an automatic license grant". Generation does not eliminate the need for rights and attribution analysis.

C:

Question 23

During an AI-assisted software release, the following condition is confirmed: A suggested snippet includes a copyright notice from another project. Which approach is the most defensible?

  1. Apply organizational IP review rather than inventing an automatic license grant
  2. Keep human-reviewed commits and appropriate provenance records
  3. Compare the public-code reference and review its license obligations
  4. Preserve relevant attribution and consult the license before integrating

Explanation

Correct Answer

D:

Select the action "Preserve relevant attribution and consult the license before integrating". Embedded notices can indicate externally sourced material with obligations. It is the specific match for the scenario in which A suggested snippet includes a copyright notice from another project.

Incorrect Answers

A:

  1. Apply organizational IP review rather than inventing an automatic license grant
  2. Keep human-reviewed commits and appropriate provenance records
  3. Preserve relevant attribution and consult the license before integrating
  4. Design an original solution from requirements without copying protected source

Explanation

Correct Answer

B:

The choice "Keep human-reviewed commits and appropriate provenance records" matches the requirement: A release audit cannot trace which AI-generated changes were accepted. Traceability supports review and remediation of uncertain sources. This is the best-supported approach under the stated constraint.

Question 26

A maintainer using GitHub Copilot finds, the following condition is confirmed: Copilot proposes removing all failed jobs to clear a deployment dashboard. What is the best next step under this constraint?

  1. Inspect schema dependencies and rehearse rollback before execution
  2. Require human review, automated tests, and protected merge controls
  3. Review the operations impact before approving a destructive action
  4. Require risk-owner approval and staged evaluation on labeled cases

Explanation

Correct Answer

C:

The appropriate action is "Review the operations impact before approving a destructive action". A suggested command must not be executed merely because it looks efficient. The decisive condition is Copilot proposes removing all failed jobs to clear a deployment dashboard.

Incorrect Answers

A:

The alternative "Inspect schema dependencies and rehearse rollback before execution" addresses A generated database migration drops a column still used by reporting. Apparently local changes can disrupt downstream consumers. It does not resolve Copilot proposes removing all failed jobs to clear a deployment dashboard; the correct choice is "Review the operations impact before approving a destructive action". A suggested command must not be executed merely because it looks efficient.

B:

For the different scenario A team plans to merge hundreds of agent-created changes without code review, "Require human review, automated tests, and protected merge controls" could be appropriate. Autonomous authorship does not provide independent production acceptance. The present requirement is Copilot proposes removing all failed jobs to clear a deployment dashboard, which calls for "Review the operations impact before approving a destructive action". A suggested command must not be executed merely because it looks efficient.

D:

The action "Require risk-owner approval and staged evaluation on labeled cases" is useful when An AI-generated fraud rule would automatically reject legitimate customer payments. Consequential decisions require domain oversight and measurable safeguards. Under the stated condition Copilot proposes removing all failed jobs to clear a deployment dashboard, instead choose "Review the operations impact before approving a destructive action". A suggested command must not be executed merely because it looks efficient.

Question 27

While investigating a coding workflow, the following condition is confirmed: An AI-generated fraud rule would automatically reject legitimate customer payments. Which approach is the most defensible?

  1. Require human review, automated tests, and protected merge controls
  2. Require risk-owner approval and staged evaluation on labeled cases
  3. Review the operations impact before approving a destructive action
  4. Deny unnecessary scope and use a controlled least-privilege investigation

Explanation

Correct Answer

B:

Select the action "Require risk-owner approval and staged evaluation on labeled cases". Consequential decisions require domain oversight and measurable safeguards. It is the specific match for the scenario in which An AI-generated fraud rule would automatically reject legitimate customer payments.
