Option A: Manually update the branch protection settings in each repository one by one,Option B: Create an organization-wide repository ruleset that targets the default branch of all repositories,Option C: Write a GitHub Actions workflow to check branch settings every hour,Option D: Assign the maintainer role to all team members across all repositories,Option E: Restrict organization access to internal users only,Option F: Disable repository forks at the enterprise level,Correct Answer: B,Explanation: Option A is incorrect because manual updates are not simultaneous and do not scale well, Option B is correct because organization-wide rulesets allow administrators to enforce branch protection policies across multiple or all repositories from a single central location, Option C is incorrect because while Actions can check states, rulesets natively enforce policies without custom scripting, Option D is incorrect because granting maintainer roles gives excessive permissions rather than enforcing specific branch protections, Option E is incorrect because restricting access does not configure branch protection rules, Option F is incorrect because disabling forks is a security setting unrelated to branch protection rules,Question 2: Security and Compliance When configuring GitHub Advanced Security, which feature should you enable to automatically detect exposed credentials in your repository commit history? Option A: CodeQL analysis,Option B: Dependabot alerts,Option C: Secret scanning,Option D: Security advisories,Option E: Dependency review,Option F: Branch protection rules,Correct Answer: C,Explanation: Option A is incorrect because CodeQL is used for finding semantic vulnerabilities in code rather than exposed credentials, Option B is incorrect because Dependabot alerts you to vulnerable dependencies in your manifest files, Option C is correct because secret scanning actively searches your repository for known types of secrets and credentials to prevent unauthorized access, Option D is incorrect because security advisories are used to privately discuss and fix vulnerabilities in your project, Option E is incorrect because dependency review helps you understand dependency changes in pull requests, Option F is incorrect because branch protection rules enforce workflows rather than scan for exposed secrets,Question 3: Organization Administration You need to ensure that specific external contractors only have read access to a single repository within your GitHub organization without adding them to a team, How should you configure their access?
