Questions # 11:

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?

Options:

GitHub App

GitHub Copilot Extension

GitHub Models

GitHub Action

Answer

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.

Questions # 12:

When comparing Group SCIM to Team Sync for identity management in GitHub Enterprise, which statement is Correct?

Options:

Group SCIM requires less initial configuration than Team Sync.

Team Sync supports more identity providers than Group SCIM.

Team Syncprovides more automated user deprovisioningthan Group SCIM.

Group SCIM enablescentralized user and group management through the IdP.

Answer

Explanation

Group SCIM lets you manage both user accounts and group memberships centrally in your identity provider - automatically provisioning, updating, and deprovisioning users and groups in GitHub - whereas Team Sync only mirrors IdP group membership into existing GitHub teams.

Questions # 13:

How does GitHub support compliance requirements for enterprises?

Options:

GitHub provides configurable controls such as an audit log, SAML authentication, and enterprise rulesets.

GitHub disables all external collaboration features.

GitHub only allows those with repository owner (admin) permissions to write changes to repositories.

GitHub automatically encrypts user passwords in plaintext for quick access.

Answer

Explanation

GitHub Enterprise gives you a suite of configurable controls - like a comprehensive audit log, enforced SAML single sign‑on, and enterprise‑level rulesets - that you can tailor and enforce to meet your organization’s compliance mandates.

Questions # 14:

An organization wants to share a single API key required for their Actions workflows. They need to restrict its use to only a subset of repositories. Where should they configure the secrets to minimize maintenance?

Options:

Repository secrets

Environment secrets

Organization secrets

Development environment secrets

Answer

Explanation

By defining the API key as an organization secret, you centralize management and can grant access only to the subset of repositories you choose - eliminating per‑repo duplication while enforcing the desired scope.

Questions # 15:

Which practice helps avoid service disruption when consuming GitHub APIs at scale?

Options:

Designingyour application to work within GitHub's rate limits

Using multiple tokens to bypass limits

Caching all API responses permanently

Ignoring secondary rate limits

Answer

Explanation

Designing your integration to stay within GitHub’s documented rate limits—by batching requests, using conditional requests, handling 429 responses with back‑off, and monitoring the X‑RateLimit-* headers - ensures you won’t be temporarily throttled or cut off when you hit secondary limits.

Questions # 16:

Options:

writing scripts.

installing GitHub Enterprise Server.

Questions # 17:

How does Dependabot determine which security update PRs to open?

Options:

It waits for manual triage of all CVEs.

It uses the dependency graph and Dependabot alerts to open PRs for patched versions.

It reads the GitHub Issues and automatically suggests fixes.

It compares your codebase to the GitHub Trending list.

Answer

Explanation

Dependabot relies on your repository’s enabled Dependency Graph and Dependabot Alerts to identify vulnerable dependencies; it then automatically opens pull requests to update to the patched versions that resolve those alerts.

Questions # 18:

Your organization wants to reduce costs. Which of the following actions should you take?

Options:

Grant all users admin permissions

Remove all outside collaborators

Regularly audit for inactive users

Disable SAML SSO for members

Answer

Explanation

Regularly auditing for inactive (dormant) users lets you suspend or remove accounts that aren’t consuming seats - freeing up licenses and directly lowering your per‑user subscription costs.

Questions # 19:

Which of the following is true about outside collaborators in a GitHub organization?

Options:

They are granted explicit access to specific repositories.

They inherit organization-wide policies, such as SSO requirements.

They have access to all private repositories by default.

They appear in the organization's internal member list.

Answer

Explanation

Outside collaborators aren’t organization members; instead, they’re granted explicit access - at read, write, or admin level - to only the repositories you choose.
