How often are time-based Trigger functions recalculated? -
ANSWERS-Every 30 seconds no matter what update interval is

What are the two possible return values for the 'nodata' Trigger

True or False. Zabbix supports dependencies between hosts directly. -
ANSWERS-False
When setting up Trigger dependencies, what three things will happen
to problems generated by dependent triggers? - ANSWERS-They will
