A systems administrator is changing the password policy within an enterprise environment and wants this update implemented on all systems as quickly as possible. Which of the following operating system security measures will the administrator most likely use?

Pushing a Group Policy Object (GPO) update is the most efficient method to apply a new password policy across all systems in an Active Directory domain. GPOs are designed to manage configurations for users and computers centrally, ensuring consistent application of security settings like password policies. Once updated, the changes propagate to all domain-joined machines, typically within 90 minutes or upon the next policy refresh. Deploying PowerShell scripts could achieve a similar outcome but would require more complex scripting, execution, and verification across all machines, making it less streamlined than GPOs for policy enforcement. Enabling PAP (Password Authentication Protocol) is an authentication protocol, not a mechanism for distributing policy updates. Updating EDR (Endpoint Detection and Response) profiles relates to endpoint security software configurations, not operating system password policies.
