Two primary data storage locations in Databricks are DBFS root storage and external object storage mounted using dbutils.fs.mount().
dbutils.fs.mount()
Which statement is accurate regarding these storage options?
A
DBFS is a file system protocol that allows users to interact with files stored in object storage using syntax and guarantees similar to Unix file systems.
B
By default, both the DBFS root and mounted data sources are only accessible to workspace administrators.
C
The DBFS root is the most secure location to store data, because mounted storage volumes must have full public read and write permissions.
D
Neither the DBFS root nor mounted storage can be accessed when using %sh in a Databricks notebook.
E
The DBFS root stores files in ephemeral block volumes attached to the driver, while mounted directories will always persist saved data to external storage between sessions.
