Which type of nodes should be proposed?
A . Protocol nodes with SAS drives
B . Storage nodes with SSD drives
C . Storage nodes with SAS drives
D . Protocol nodes with SSD drives
Answer: B
Explanation:
A scale-out NAS system is comprised of multiple NAS storage nodes with internal or external storage.
