Certified instructors verify every question for 100% accuracy, providing detailed, step-by-step explanations for each.

  • A.

    GitHub Pages Settings.

  • B.

    GitHub Actions Logs.

  • C.

    Repository Settings > Manage Access.

  • D.

    Branch Protection Rules.

Correct Answer & Rationale:

Answer: C

Question 2 Microsoft GH-100
QUESTION DESCRIPTION:

What distinguishes Enterprise Managed Users (EMUs) from standard GitHub accounts?

  • A.

    EMUs are fully controlled by an IdP and cannot log in with personal credentials

  • B.

    EMUs can only be created using email invites

  • C.

    EMUs are managed in GitHub and use GitHub authentication

  • D.

    EMUs are only available for GitHub Enterprise Server

Correct Answer & Rationale:

Answer: A

Explanation:

EMU accounts are provisioned and authenticated exclusively through your identity provider - users sign in via the IdP and cannot use or manage GitHub-native credentials.

Question 3 Microsoft GH-100
QUESTION DESCRIPTION:

Which of the following correctly describes the difference between controlling actions at the enterprise level versus the organization level in GitHub?

  • A.

    Enterprise policies and organization policies are independent, with organization policies taking precedence for repositories within the organization.

  • B.

    Enterprise policies configure mandatory settings for organizations.

  • C.

    Enterprise policies apply only to public repositories, while organization policies apply to public, internal, and private repositories.

  • D.

    Enterprise policies can block specific actions, while organization policies can only enable or disable actions entirely.

Correct Answer & Rationale:

Answer: B

Explanation:

Enterprise policies let you define and enforce mandatory settings across all member organizations - organization ‑ level policies then operate within the options that the enterprise policy exposes.

Question 4 Microsoft GH-100
QUESTION DESCRIPTION:

A token was used to access an organization's resource via API. What fields in the audit log help determine who used it?

  • A.

    The token's permissions and the geographic region of access

  • B.

    The token expiration date

  • C.

    The GitHub Actions runner name

  • D.

    The token ID, requesting IP address, and associated user

Correct Answer & Rationale:

Answer: D

Explanation:

The audit log records the token’s identifier (the hashed_token value), the source IP address of the request, and the actor (the user or app) associated with that token, allowing you to trace exactly who used it.

Question 5 Microsoft GH-100
QUESTION DESCRIPTION:

In a GitHub repository using Dependabot, which of the following best describes the purpose of the .github/dependabot.yml file?

  • C.

    It enables GitHub to scan for secrets in dependency files.

  • D.

    It encrypts dependency versions before storing them in the repo.

Correct Answer & Rationale:

Answer: A

Explanation:

The .github/dependabot.yml file defines Dependabot’s package-ecosystem, the directories to inspect, and the update schedule (daily/weekly/monthly), controlling when and where Dependabot checks for new versions.

Question 6 Microsoft GH-100
QUESTION DESCRIPTION:

Why would someone choose to configure a security policy?

  • A.

    To communicate corporate security and compliance policies for end users on a private repository.

  • B.

    To provide information on an open source repository for open source collaborators and researchers that may need to report and disclose sensitive security findings to maintainers securely.

  • C.

    To prevent anyone from pushing to the repository without approval.

  • D.

    To define which open source packages are permitted for use as part of that repository.

Correct Answer & Rationale:

Answer: B

Explanation:

A security policy (the SECURITY.md file) lets maintainers of an open source repository provide clear, private instructions for collaborators and external researchers on how to report and disclose security vulnerabilities responsibly.

Question 7 Microsoft GH-100
QUESTION DESCRIPTION:

What makes GitHub Apps a more secure choice for automation over OAuth Apps?

  • A.

    GitHub Apps always require two-factor authentication.

  • B.

    GitHub Apps can only be installed by organization owners.

  • C.

    GitHub Apps are limited to read-only access and cannot write to repositories.

  • D.

    GitHub Apps authenticate as an app with fine-grained permissions, not as a user.

Correct Answer & Rationale:

Answer: D

Explanation:

GitHub Apps authenticate as themselves with fine ‑ grained, installation ‑ scoped permissions and short ‑ lived tokens - rather than inheriting a user’s broad OAuth scopes - minimizing blast radius and aligning with least ‑ privilege principles.

Question 8 Microsoft GH-100
QUESTION DESCRIPTION:

You need GitHub to automatically notify a third-party service any time a new repository is created. You want to avoid writing custom code. The vendor has told you that they have a tool in the GitHub Marketplace. Which type of tool do you need?

  • A.

    GitHub App

  • B.

    GitHub Copilot Extension

  • C.

    GitHub Models

  • D.

    GitHub Action

Correct Answer & Rationale:

Answer: A

Explanation:

You need a GitHub App. Marketplace integrations that listen for events like repository.created and send notifications are delivered as GitHub Apps, since they can subscribe to organization ‑ level webhooks without you writing custom code.

Question 9 Microsoft GH-100
QUESTION DESCRIPTION:

Which of the following are valid ways to pass data to a reusable workflow in a separate repository?

  • A.

    Use environment variables to pass data directly to the reusable workflow.

  • B.

  • C.

  • D.

Correct Answer & Rationale:

Answer: B, C

Explanation:

You declare named inputs in the reusable workflow’s on.workflow_call block and then pass values from the caller using the with keyword, allowing the called workflow to consume those parameters.

You define required secrets in the caller repository and supply them to the reusable workflow via the secrets keyword in the workflow-call step, ensuring sensitive values are securely passed.

Question 10 Microsoft GH-100
QUESTION DESCRIPTION:

A GitHub Enterprise administrator is planning to implement SAML SSO across their company. Which of the following correctly distinguishes enterprise-wide SAML SSO from organization-level SAML SSO?

  • A.

    Enterprise-wide SAML SSO requires less initial administrative overhead than organization-level implementation.

  • B.

    Enterprise-wide SAML SSO allows different organizations to use different authentication methods.

  • C.

    Enterprise-wide SAML SSO immediately removes users who fail to authenticate via the IdP.

  • D.

    Enterprise-wide SAML SSO ensures users authenticate through the same IdP across all organizations.

Correct Answer & Rationale:

Answer: D

Explanation:

Enterprise ‑ wide SAML SSO enforces a single IdP across all member organizations—its configuration overrides any per ‑ organization SAML settings, so everyone must authenticate through the same provider.
