   What is a common method for handling a drive failure in a volume group?

   • AThe system automatically redistributes data across all remaining drives without a hot spare.
   • BThe failed drive is automatically replaced with a new drive from the vendor's spare inventory.
   • CThe system automatically rebuilds the data using a dedicated hot spare drive if one is configured.
   • DThe volume group becomes unavailable until the failed drive is replaced.

   A small business needs to create a volume group for their file server. They have 4 drives of 2TB each. The workload is light with occasional reads and writes. They want to maximize capacity while tolerating one drive failure. What RAID level should they choose?

   • ARAID 5
   • BRAID 6
   • CRAID 0
   • DRAID 1

   A database admin needs to create a DDP for a new transactional database. They have 12 drives of 1.2TB 10K RPM SAS. The workload is write-heavy with high IOPS. They want to ensure the DDP can tolerate two simultaneous drive failures. What is the minimum number of drives required for the DDP to tolerate two failures?

   • A12 drives with 3-drive fault tolerance
   • B12 drives with 2-drive fault tolerance
   • C8 drives with 2-drive fault tolerance
   • D12 drives with 1-drive fault tolerance

   A hospital's PACS (Picture Archiving and Communication System) stores large radiology images. The storage admin must maximize usable capacity from a 24-drive shelf of 10TB NL-SAS drives while tolerating occasional drive failures without manual intervention. The workload is sequential reads and writes with low IOPS demand. Which configuration best meets these requirements?

   • ACreate a DDP using all 24 drives with a single pool
   • BCreate a DDP with 20 drives and leave 4 as dedicated hot spares
   • CCreate two RAID 5 volume groups of 12 drives each
   • DCreate a volume group with RAID 6 using all 24 drives

   How does DDP typically compare to a volume group in terms of rebuild time after a drive failure?

   • ADDP rebuilds are faster because data is rebuilt in parallel across all drives in the pool.
   • BBoth have identical rebuild times because they use the same RAID algorithms.
   • CRebuild time depends only on the drive speed, not on the data layout.
   • DVolume group rebuilds are faster because they use a dedicated spare drive.
