GH-500 Exam Dumps - Microsoft GitHub Administrator Questions and Answers

To proactively address secret scanning:

Webhooks can be configured to listen for secret scanning events. This allows automation, logging, or alerting in real-time when secrets are detected.

Documenting secure development practices (like using environment variables or secret managers) helps reduce the likelihood of developers committing secrets in the first place.

Dismissal based on age is not a best practice without triage. SCIM deals with user provisioning, not scanning alerts.

Dependabot alert and advisory details can include a CVE identifier, a GHSA identifier, and associated CWE classifications. CVE provides the standardized identifier for a publicly known vulnerability. GitHub assigns a unique GHSA ID to advisories in the GitHub Advisory Database, while CWE identifies the underlying category or class of software weakness associated with the vulnerability. GitHub's Dependabot alert interface exposes these values when they are available. EPSS is also now surfaced by GitHub and can be used to prioritize alerts, but EPSS is a probability-based exploit-risk score, not one of the three vulnerability identifiers/classifications being tested by this question. SAST describes a security-analysis methodology rather than an advisory classification. Therefore, the intended selections are CVE, GHSA, and CWE: C, D, and E.

GitHub enables the dependency graph by default for public repositories. The graph analyzes supported manifest and lock files and identifies dependencies declared in those files. When a dependency is added or changed in a supported manifest on the repository's default branch, GitHub updates the dependency graph automatically. Private repositories can also use the dependency graph, but the feature must be enabled unless an organization or enterprise configuration enables it automatically. Forking a repository does not itself constitute the dependency declaration that this question describes. Therefore, under default settings, adding a new dependency to a manifest in a public repository is the scenario that causes GitHub's dependency graph to identify and represent that dependency.

The GitHub Code Scanning API includes endpoints that allow you to:

List alerts for a repository (filtered by branch, state, or tool) — useful for monitoring security over time.

Get a single alert by its ID to inspect its metadata, status, and locations in the code.

However, GitHub does not support modifying the severity of alerts via API — severity is defined by the scanning tool (e.g., CodeQL). Likewise, alerts cannot be deleted via the API; they are resolved by fixing the code or dismissing them manually.

In a dependabot.yml configuration file, package-ecosystem is a required key . It defines the package manager being used in that update configuration (e.g., npm, pip, maven, etc.).

Without this key, Dependabot cannot determine how to analyze or update dependencies. Other keys like rebase-strategy or commit-message are optional and used for customizing behavior.

Using the Custom setting allows you to subscribe to specific event types, such as Dependabot alerts or vulnerability notifications, without being overwhelmed by all repository activity. This is essential for repository maintainers who need fine-grained control over what kinds of events trigger notifications.

This setting is configurable per repository and allows users to stay aware of critical issues while minimizing notification noise.

The best way to prioritize secret scanning alerts is to filter by active secrets — these are secrets GitHub has confirmed are still valid and could be exploited. This allows security teams to focus on high-risk exposures that require immediate attention.

Sorting by time or filtering by custom patterns won’t help with risk prioritization directly.
