I think answers are not correct. Does anyone know what will be the right answer here?
A&B darling are correct
A B
A is right. DBFS was the only shared storage file system prior 12.1.0.2. Now ACFS is available
B is right. DBFS is POSIX compliant and was the only storage solutin accessible from db nodes
C is wrong. you can bulk load data from outside exadata
D is wrong. DBFS_DG is the default disk group name, but can be other name
E is wrong. DBFS is not only available in exadata
So A.B. are correct
