SK0-003 · Question #10
Which of the following provides the MOST storage capacity without fault tolerance?
The correct answer is D. JBOD. Just a Bunch Of Disks (JBOD) provides the maximum possible raw storage capacity by combining all drives into a single logical volume without any overhead for data redundancy. This configuration offers no fault tolerance.

Why each option
Just a Bunch Of Disks (JBOD) provides the maximum possible raw storage capacity by combining all drives into a single logical volume without any overhead for data redundancy. This configuration offers no fault tolerance.
RAID 1 (mirroring) provides fault tolerance by duplicating data across two drives, effectively halving the usable storage capacity.
SAS (Serial Attached SCSI) is an interface technology for connecting storage devices, not a storage configuration method that determines capacity or fault tolerance.
SATA (Serial Advanced Technology Attachment) is an interface technology for connecting storage devices, not a storage configuration method that determines capacity or fault tolerance.
JBOD (Just a Bunch Of Disks) combines multiple physical drives into a single logical volume, utilizing the full capacity of each drive without any striping, mirroring, or parity for fault tolerance. This maximizes raw storage capacity as there is no space reserved for redundancy.
