Azure Data Scientists Associate Practice Exam

Which class can be used to create a schedule that runs a pipeline once per week?

1. RecurrencePattern

2. JobSchedule

3. RecurrenceTrigger

4. IntervalTrigger

The correct answer is: RecurrenceTrigger

The choice of RecurrenceTrigger is accurate because this class is specifically designed to facilitate the scheduling of pipelines at set intervals or specific times. By utilizing a RecurrenceTrigger, you can define a recurrence pattern, such as running a pipeline once per week. This feature is essential in orchestrating data workflows, where timely execution of processes is crucial, such as for weekly data aggregation or maintenance tasks. In contrast, the other options do not directly serve the purpose of scheduling in the same manner. RecurrencePattern is primarily used to define the details of how often a schedule occurs but does not itself initiate runs. JobSchedule may refer to general scheduling mechanisms but is not the class used specifically for pipelines in Azure Data Factory. IntervalTrigger generally implies execution based on a time interval rather than a recurring schedule, which better describes the behavior of RecurrenceTrigger. Therefore, RecurrenceTrigger is the most appropriate choice for creating a weekly schedule for pipeline execution.
