GH-100 Question #26: Real Exam Question with Answer & Explanation

Question

Which of the following is a key benefit of using GitHub Marketplace Apps in an enterprise?

Options

• AThey guarantee no downtime during enterprise GitHub maintenance windows
• BThey often include integrations with external services, reducing the need for custom code
• CApps eliminate the need for GitHub Actions entirely
• DAll apps come pre-approved by GitHub's internal security team

Explanation

GitHub Marketplace Apps are pre-built integrations that connect GitHub with external tools and services - such as CI/CD platforms, security scanners, and project management systems - meaning teams can adopt these capabilities without writing and maintaining custom code themselves. Option B is correct because this out-of-the-box interoperability is the primary value proposition of Marketplace Apps in an enterprise context.

Why the distractors are wrong:

• A is false - Marketplace Apps have no influence over GitHub's own maintenance windows or uptime guarantees; those are governed by GitHub's SLA.
• C is false - Apps and GitHub Actions are complementary; Apps often trigger or work alongside Actions rather than replacing them.
• D is false - GitHub reviews apps for basic marketplace standards, but does not provide a blanket security pre-approval; enterprises must still conduct their own security vetting.

Memory tip: Think of Marketplace Apps as a "plug-in store" - their core benefit is plug-and-play integrations, not uptime promises, Actions replacement, or security guarantees.
