Exam DBDEA Topics: ingestion Difficulty: easy

A team's ingestion notebooks currently reference raw files by full s3:// URIs, with long-lived cloud credentials pasted directly into the code. The governance program now requires that every landing location be a centrally governed path, that no cloud credentials appear in notebooks, and that access be granted and revoked through one central permission model. Where should the landing files be stored?

Options (Reading Mode) Click to filter discussion →
  1. A. In the current bucket as is, with instance profiles referenced inside each notebook and updated by hand whenever the cloud credentials rotate
  2. B. In the bucket through DBFS mounts configured with cloud credentials on the cluster, the traditional pattern for production landing areas
  3. C. In a Unity Catalog volume, using /Volumes/catalog/schema/volume paths governed by READ VOLUME and WRITE VOLUME privileges
  4. D. In a public bucket with anonymous access enabled, so the notebooks can keep using plain s3:// URLs without credential management
