Which action is performed to enable a system to utilize selected Red Hat products?

To enable a system to utilize selected Red Hat products, the proper action to take is to subscribe. When a system subscribes to Red Hat products, it establishes a relationship with Red Hat's content delivery systems, allowing the system to access software updates and additional content associated with the subscribed products. This process connects the system to Red Hat's repositories, ensuring that it remains secure and up to date with the latest enhancements, bug fixes, and features.

Subscribing is crucial for maintaining compliance and support for the Red Hat products in use. With an active subscription, users can receive technical support as well as access to knowledge bases and other resources that help manage and troubleshoot their environments. This relationship is foundational for enterprises that rely on Red Hat for their critical infrastructure and services.

Other actions like activating, authorizing, or enrolling may pertain to different contexts or software functionalities, but they do not directly refer to the action needed to gain access to Red Hat products and their associated capabilities. Hence, subscribing is the most appropriate and precise choice for this scenario.
