The management team notices that new accounts that are set up manually do not always have correct access or permissions. Which of the following automation techniques should a systems administrator use to streamline account creation?

A user provisioning script automates the creation of new user accounts, assigning appropriate access and permissions based on predefined templates or roles. This ensures consistency and accuracy, eliminating manual errors often seen with new accounts. Guard rail scripts enforce policies and configurations but don't create accounts. A ticketing workflow manages requests and tasks but doesn't automate the account creation itself. An escalation script automates actions when certain conditions are met, such as a problem not being resolved, but it's not designed for initial account setup.
