What is the function of role services on a server?

Role services on a server are designed to enhance and extend the main roles of that server by adding specific functionalities. Each main role, such as web server, application server, or file server, can have associated role services that enable additional features or capabilities, effectively allowing the server to perform a wider range of tasks tailored to various needs.

For instance, a web server role might include role services for security, caching, or database connectivity, which complement the primary function of serving web pages. This modular approach not only facilitates efficient management but also ensures that servers can be customized according to the requirements of an organization.

The other options do not accurately describe the role of role services. Hinder performance or limit capabilities contradicts the purpose of enhancements through role services, and while user authentication is important, it is just one aspect of server functionality and not a comprehensive description of role services.
