Which of the following is the LEAST complex hardware model for Fibre Channel?

A.
Direct Attached Storage (DAS)

B.
Just a Bunch Of Disks (JBODs)

C.
External Storage Array

D.
Storage Networks

Explanation:
Just a Bunch Of Disks (JBODs) is a hardware model for Fibre Channel disk storage and is the least complex and cheapest storage Fibre Channel option. It is achieved through internal or external configurations in peripheral bays. Disks are attached to an I/O channel and the server operating system addresses and manages each disk separately.
Incorrect
Answers:
A: Direct Attached Storage (DAS) is not a Fibre Channel hardware model. It is a storage device or array that is directly attached to a host system and can be an internal hard drive in a server or a hard drive array housed in an external case but directly attached to the server.
C: External storage arrays is a hardware model for Fibre Channel disk storage and is managed internally and connect to the server as a single unit through an I/O channel. The server does not address individual disks, or control the placement of data on those disks.
D: Storage networks is a hardware model for Fibre Channel disk storage and allows the centralization of storage for multiple servers on a special type of network called either a Storage Area Network (SAN), or Network Attached Storage (NAS).
