Pass the GitHub Certification GitHub-Advanced-Security Questions and answers with ValidTests

To grant specific users access toview and manage secret scanning alerts, you do this via theSettingstab of the repository. From there, under the"Code security and analysis"section, you can add individuals or teams with roles such assecurity manager.

The Security tab only displays alerts; access control is handled in Settings.

If a secret isintentionally used in a test environmentandposes no real-world security risk, you may close the alert with the reason"used in tests". This helps reduce noise and clarify that the alert was reviewed and accepted as non-critical.

Just being in a test file isn't enough unless itspurpose is purely for testing.

You shoulddismissa code scanning alert if the flagged code isnot a true security concern, such as:

Code in test files

Code paths that are unreachable or safe by design

False positives from the scanner

Fixing the code would automaticallyresolvethe alert — not dismiss it. Dismissing is for valid exceptions or noise reduction.

To change the threshold that defines whether a pull request fails due to code scanning alerts (such as blocking merges based on severity), the user must haveAdminaccess on the repository. This is because modifying these settings falls under repository configuration privileges.

Users with Write, Maintain, or Triage roles do not have the required access to modify rulesets or status check policies.

Comprehensive and Detailed Explanation:

When configuring Dependabot via the dependabot.yml file, the following fields are mandatory for each update configuration:

directory: Specifies the location of the package manifest within the repository. This tellsDependabot where to look for dependency files.​

package-ecosystem: Indicates the type of package manager (e.g., npm, pip, maven) used in the specified directory.​

schedule.interval: Defines how frequently Dependabot checks for updates (e.g., daily, weekly). This ensures regular scanning for outdated or vulnerable dependencies.​

The milestone field is optional and used for associating pull requests with milestones. The allow field is also optional and used to specify which dependencies to update.​

By default,users with Write, Maintain, or Admin permissionswill receive notifications for newDependabot alerts. However,Write permissionis theminimum levelneeded to be automatically notified. Users with only Read access do not receive alerts unless added explicitly.

GitHub automatically closes a code scanning alert when the vulnerable code is fixedin the same branch where the alert was generated, usually via acommit inside a pull request. Simply clicking or triaging an alert does not resolve it. The alert is re-evaluated after each push to the branch, and if the issue no longer exists, it is marked as resolved.

Dependabot builds a dependency graph by analyzing package manifests and lockfiles in your repository. This graph includes both direct and transitive dependencies. It then compares this graph against the GitHub Advisory Database, which includes curated, security-reviewed advisories.

This method provides a comprehensive and automated way to discover all known vulnerabilities across your dependency tree.

Bydefault,no repositoriesreceive Dependabot alerts unless configuration is explicitly enabled. GitHub doesnotenable Dependabot alerts automatically for any repositories unless:

The feature is turned on manually

It's configured at the organization or enterprise level via security policies

This includes public, private, and enterprise-owned repositories —manual activation is required.

When using a SARIF-compatible tool within GitHub Actions, it's necessary to explicitly add a step in your workflow to upload the analysis results. This is typically done using the upload-sarif action, which takes the SARIF file generated by your tool and uploads it to GitHub for processing and display in the Security tab. Without this step, the results won't be available in GitHub's code scanning interface.​
