Which of the following is a characteristic of server features? Select two.

A characteristic of server features is that they provide functions that enhance an installed role. This means that server features are designed to add additional capabilities and improve the overall performance or functionality of a server role. For instance, if a server role is primarily handling web services, certain features might enable advanced logging, enhanced security settings, or additional management tools that enrich the web service functionalities.

Another valid characteristic is that a server feature can be a standalone function. This indicates that some features are not necessarily tied to a specific role and can operate independently to offer specific services or functionalities that may benefit the server's overall operation.

In the context of server architectures, it is important to understand that while features may be installed on the server, they are not all permanent. Many features can be added or removed as needed. Furthermore, requiring a separate server to operate is not a characteristic of server features; features typically enhance the capabilities of the existing server rather than needing entirely separate infrastructures.
