GitHub-Advanced-Security Premium Exam Questions

Comprehensive and Detailed Explanation:

For code scanning to be triggered on a specific branch, the branch must contain the appropriate workflow file, typically located in the .github/workflows directory. This YAML file defines the code scanning configuration and specifies the events that trigger the scan (e.g., push, pull_request).​

Without the workflow file in the branch, GitHub Actions will not execute the code scanning process for that branch. The repository's visibility (private or public), the status of secret scanning, or the activity level of developers do not directly influence the triggering of code scanning.​

Dependabot security updatesareautomated pull requeststriggered when GitHub detects avulnerabilityin a dependency listed in your manifest or lockfile. These PRs upgrade the dependency to theminimum safe versionthat fixes the vulnerability.

This is separate from regular updates (which keep versions current even if not vulnerable).

Comprehensive and Detailed Explanation:

Before defining a custom pattern for secret scanning in a repository, you must enable secretscanning for that repository. Secret scanning must be active to utilize custom patterns, which allow you to define specific formats (using regular expressions) for secrets unique to your organization.​

Once secret scanning is enabled, you can add custom patterns to detect and prevent the exposure of sensitive information tailored to your needs.​

To create or modify acode scanning workflow file(typically under .github/workflows/codeql-analysis.yml), you must haveWriteaccess to the repository.

Write permission allows you to commit the workflow file, which is required to run or configure code scanning using GitHub Actions.
