Databricks Certified Data Engineer - Associate

Explanation:

In Databricks, when you create a database using the CREATE DATABASE command without specifying a location, it defaults to the Hive metastore warehouse directory. The default location is dbfs:/user/hive/warehouse/. Within this directory, each database gets its own subdirectory.

Key points:

1. Default Location: dbfs:/user/hive/warehouse/ is the default Hive warehouse directory in Databricks.
2. Database Subdirectory: When you create the customer360 database, it will create a subdirectory customer360.db within the warehouse directory.
3. Complete Path: The actual database location would be dbfs:/user/hive/warehouse/customer360.db/.
4. Option Analysis:
   • Option A: Incorrect - There is no standard /user/hive/database/ path in Databricks.
   • Option B: Correct - This is the default warehouse directory where databases are stored.
   • Option C: Incorrect - Databases are not stored directly under /user/hive/.
   • Option D: Incorrect - The default location is known and doesn't require additional information.

Note: If you want to specify a custom location, you would use the LOCATION clause in the CREATE DATABASE command, but since no location was specified in this command, it uses the default warehouse directory.
