Exam DP-750 Topic 1 Question 5 Discussion

Actual exam question for Microsoft's DP-750 exam
Question #: 5
Topic #: 1
You have an Azure Databricks workspace that contains a job in Lakeflow Jobs named Job1.
Job! processes raw data files stored in Azure Storage.
New files arrive at unpredictable intervals.
You need to ensure that Job1 starts automatically when new files arrive and does NOT consume compute resources when no data is available.
Which type of job trigger should you use?

Suggested Answer: C Vote an answer

The correct answer is C - File Arrival trigger.
File Arrival monitors a specified Azure Storage path and fires a job run each time a new file lands there. This ticks both requirements: Job1 starts automatically in response to new data (no human involvement), and when no files arrive, no job runs - no cluster spins up, no compute cost is incurred.
Option A (scheduled) runs at fixed intervals regardless of whether files are waiting. A quiet weekend still kicks off hourly (or daily) runs, burning compute for nothing. Option B (continuous) keeps the job running perpetually, consuming resources even during long gaps between file arrivals - exactly what 'does NOT consume compute resources when no data is available' rules out. Option D (manual) requires a person to trigger every run, which is unsuitable for unpredictable arrival patterns.
