If a host belongs to multiple host groups and one group is disabled, what is the result?

The correct answer is that only the group is disabled, not the hosts. When a host belongs to multiple host groups in Zabbix, the status of the host groups does not directly affect the hosts themselves. Disabling a host group simply prevents that specific group from being used in any monitoring or operations; it does not disable the hosts that are members of that group.

Hosts remain functional and active irrespective of the status of their host groups. This means any active monitoring, alerts, or data collection for those hosts will continue as long as they remain enabled individually or belong to other active host groups. The architecture of Zabbix is designed to provide flexibility, allowing users to manage their hosts based on different criteria without impacting the hosts themselves when a particular group becomes inactive.

Thus, understanding the distinction between host groups and individual hosts is crucial for effective monitoring and management of resources in Zabbix.
