Exam C_SIGPM_2403 Topic 1 Question 61 Discussion

Based on the BPMN documentation provided, Timer Events and Conditional Events share two key characteristics:
B. They cannot be used as end events [1],
Both Timer Events and Conditional Events are designed to react to external conditions or time-based triggers. The documentation shows that these event types are only available as start events and intermediate catching events, but not as end events. End events are always throwing events that conclude a process, while timer and conditional events are inherently reactive in nature.
D. They can only be catching-type events [1],
Both event types are exclusively catching events because:


Timer Events: "A timer event cannot be triggered by the process, so they are always 'catching'" . The process can only react to points in time but cannot control time itself.


Conditional Events: "Conditional events are always catching events, as they occur out of the control of the process - but the process can react to them" [1]. These events respond to external conditions that are outside the process's control.


The documentation clearly states that both timer and conditional events are reactive by nature - they wait for external triggers (time-based or condition-based) rather than being actively triggered by the process itself. This fundamental characteristic makes them exclusively catching events that cannot function as throwing events.
