Selected Answer: C
data is expected to arrive at regular intervals, and you want to trigger a pipeline with a fixed window size. For the specific requirements mentioned, especially the need to execute every 30 minutes with a 15-minute offset and backfill data from the beginning of the day to the current time, a schedule trigger is more suitable. The tumbling window trigger is generally used for scenarios where you want to process data in fixed windows based on its arrival time.

Tumbling window is correct.

It seems correct but the 15mins offset is throwing me off. Somebody please explain. Thanks

offset refers to the delay of start of the trigger : A timespan value that must be negative in a self-dependency. If no value specified, the window is the same as the trigger itself.
