What is the function of a configuration policy?

The function of a configuration policy is to define how devices should be managed and configured. This involves setting specific guidelines and rules regarding the setup, operation, and maintenance of devices within an organization. Configuration policies ensure consistency across devices, facilitate compliance with organizational standards, and help streamline processes for deployment and management. By establishing a clear framework for device configuration, organizations can minimize errors, improve security, and enhance efficiency in their IT operations.

In terms of the other options, while outlining device capabilities, establishing user access restrictions, and monitoring device performance are important aspects of device management, they do not directly pertain to the core function of a configuration policy. Configuration policies specifically deal with the methodologies and practices for device setup and management, making option B the most relevant choice.
