GH-500 Exam Dumps - GitHub Advanced Security Exam

Validity checks — where GitHub verifies if a secret is still active — are available for partner patterns only. These are secrets issued by GitHub's trusted partners (like AWS, Slack, etc.) and have APIs for GitHub to validate token activity status.

Custom patterns and high entropy patterns do not support automated validity checks.

At organization scope, enabling Dependabot alerts broadly applies the feature to the organization's eligible repositories, rather than limiting it solely to private repositories or repositories licensed for the broader GitHub Advanced Security product. Dependabot alerts support public, private, and internal repositories, subject to repository eligibility and applicable organization or enterprise configuration. GitHub's current documentation describes organization-level management as enabling Dependabot alerts across all eligible repositories through security configurations. The feature is distinct from licensed GitHub Code Security or Secret Protection capabilities, so the setting is not restricted merely to repositories where those products are enabled. Consequently, All repositories is the intended answer in the supplied choices, with the practical qualification that GitHub applies the configuration to repositories that are eligible for the feature.

Secret validation checks whether a secret found in your repository is still valid and active with the issuing provider (e.g., AWS, GitHub, Stripe). If a secret is confirmed to be active, the alert is marked as verified , which means it's considered a high-priority issue because it presents an immediate security risk.

This helps teams respond faster to valid, exploitable secrets rather than wasting time on expired or fake tokens.

Comprehensive and Detailed Explanation:

Push protection for secret scanning custom patterns is an opt-in feature. This means that for each custom pattern defined in a repository, maintainers can choose to enable or disable push protection individually. This provides flexibility, allowing teams to enforce push protection on sensitive patterns while leaving it disabled for others.​

A repository administrator can enable secret scanning for an eligible repository that is owned by the organization, assuming the organization's GitHub plan, Secret Protection licensing, and enterprise policies permit the feature. GitHub documentation states that secret scanning alerts can be enabled for organization-owned repositories, including eligible private and internal repositories. Repository administrators manage security settings for repositories over which they have the required administrative permission. They do not obtain administrative control over separate user-owned repositories merely because those users are organization members, nor can they configure repositories owned by users outside the organization. Organization owners can also enable secret scanning across multiple organization repositories through security configurations. Accordingly, the supported scope described by the question is existing private repositories owned by the administrator's organization.

GitHub secret scanning is designed to identify credentials and other sensitive values that match supported secret patterns. Among the options listed, private keys are the supported secret type. GitHub classifies private keys such as RSA, OpenSSH, EC, and PGP private keys as generic secret patterns. These are distinct from organization-specific custom patterns, which administrators create by defining their own regular expressions. Usernames and general PII are not treated as standard secret-scanning credential patterns, while “sealed boxes” are not a supported secret category. In current GitHub terminology, generic-pattern detection is separately configurable, so it may need to be enabled for the repository. Nevertheless, of the choices presented, private keys are the valid secret-scanning type.

A Dependabot alert is only marked as resolved when the related vulnerability is no longer present in your code — specifically after you merge a pull request that updates the vulnerable dependency.

Simply viewing alerts or graphs does not affect their status. Ignoring the alert by leaving the repo unchanged keeps the vulnerability active and unresolved.

The organization-level secret-scanning control represented by this question applies to the organization's private repositories that use the applicable Advanced Security or Secret Protection capability. Public repositories are treated differently because GitHub runs secret scanning for public repositories automatically and provides that protection independently of a paid Advanced Security license. Disabling secret scanning also does not disable every other Advanced Security capability; code scanning, dependency features, and related security controls are managed separately or through security configurations. Current GitHub administration increasingly manages these features through Secret Protection and organization-level security configurations, but the principle remains that disabling the licensed secret-scanning capability affects repositories to which that configuration applies rather than universally switching off every security feature. Therefore, C is the intended answer.
