Shane is a Data architect working on designing the mount of the Databricks file system for storage. He has three storage accounts for Databricks “analytics_demo”, “dscience_demo”, “azml_demo”. 
How would it mount entries in DBFS for each of these storage objects?

Answer options:

A.“/mnt/analytics_demo”, “/mnt/dscience_demo”, “/mnt/azml_demo”
B.“/mnt/analytics_demo/dscience_demo/azml_demo”
C.“/mnt/analytics_demo/…/dscience_demo/…/azml_demo”
D.None of the above

Correct Answer: A
Option A is correct because it’s recommended from Microsoft to create separate mount entries for each object storage mounted in DBFS. For example,
storage1 to be mounted as /mnt/storage1 
storage2 to be mounted as /mnt/storage2 and nested mounts are not supported. Option B is incorrect because nested mounts are not supported. So the following structures are not supported.
“/mnt/analytics_demo/dscience_demo/azml_demo” Option C is incorrect because the following nested object mountstructures are not supported.
“/mnt/analytics_demo/…/dscience_demo/…/azml_demo”
