Exam DBDEA Topics: ingestion Difficulty: easy

A bank's security policy forbids creating event notification services or queues in its cloud storage accounts. The data team still wants Auto Loader to ingest new files from a modest source directory that receives a few dozen files per day, with minimal setup. Which file discovery mode should the team use, and why?

Options (Reading Mode) Click to filter discussion →
  1. A. File notification mode with file events, because managed file events require no cloud permission grants at all
  2. B. Classic file notification mode, because the team can create the queues themselves instead of letting Auto Loader do it
  3. C. Plain batch reads with spark.read, because Auto Loader cannot run without notification services
  4. D. Directory listing mode: the default, needing no cloud permissions beyond read access to the storage path

Correct answer: Directory listing mode: the default, needing no cloud permissions beyond read access to the storage path
