Linux file system. The system needs to tolerate the failure of two or more Fault Domains and still maintain

data integrity. The solution should be as low maintenance as possible.

What storage architecture should you suggest?

Options :

A : Use locally attached NVMe instances andconfigure RAID 0 replication between servers.

B : Implement a single instance and install an NFS server, configure and create an NFS share, and mount this as /audit on the application instances.

C : Store the data on Oracle Object Storage mounted at the/audit mount point on all the Linux instances using the default mount options.

D : Use File Storage Service(FSS). Configure FSS to operate from all Availability Domains the application servers operate in and mount the file system in the /audit folder.

Answer: D
