   Which scenario is best suited for a data-driven trigger?

   • AA job that runs every hour to check for system health metrics.
   • BA job that generates a weekly summary every Monday at 9 AM.
   • CA job that runs at the end of each month to calculate monthly KPIs.
   • DA job that processes clickstream files as soon as they are uploaded to a cloud storage bucket.

   A team is designing a pipeline that ingests data from an external API that updates at unpredictable times. The pipeline must process data as soon as it is available, and the team wants to avoid running the job when there is no new data. Which trigger type is the best practice?

   • ATime-based trigger with a long interval, such as every 24 hours.
   • BManual trigger that an operator runs when they notice new data.
   • CData-driven trigger that reacts to the API data arrival.
   • DTime-based trigger with a short interval, such as every 5 minutes.

   How does a data-driven trigger handle a situation where the expected data never arrives?

   • AIt does not run the job, so the pipeline remains idle until the data arrives.
   • BIt runs the job with a warning that data is missing.
   • CIt automatically creates a placeholder dataset and runs the job.
   • DIt runs the job at the next scheduled time anyway.

   What is the defining characteristic of a time-based trigger in a job scheduling system?

   • AIt starts a job run only when a specific file appears in a storage location.
   • BIt initiates a job run at fixed intervals or according to a cron schedule, regardless of data availability.
   • CIt runs a job whenever the underlying cluster reaches a certain utilization threshold.
   • DIt triggers a job run only after the previous run of the same job completes successfully.

   Which statement accurately compares time-based and data-driven triggers?

   • ATime-based triggers are always more reliable than data-driven triggers.
   • BTime-based triggers use fewer resources than data-driven triggers in all cases.
   • CData-driven triggers are easier to debug because they run at predictable times.
   • DData-driven triggers provide lower latency than time-based triggers when data arrives irregularly.
