What is necessary when adding devices to a Z-stat?

When adding devices to a Z-stat, it is necessary to enable specific questions to ensure that the system properly recognizes and integrates the new devices. This process typically involves configuring the Z-stat to communicate with the devices effectively, allowing for seamless operation within the system. Enabling the right questions helps to facilitate proper setup, ensuring that the devices are identified and can be configured according to their specific settings and functionalities.

The other options, while they might seem relevant, are not the primary requirements for this process. A manual reset might be relevant in some contexts, but it is not inherently necessary for adding devices. A firmware update could enhance device compatibility or functionality, but it is not a mandatory step in the addition process itself. Similarly, a full system reboot may refresh the system, but it does not directly pertain to the initial stages of adding devices to the Z-stat.
