   A company has a thin-provisioned volume that is used by a file server. The file server deletes many files daily, but the storage administrator has noticed that the volume's used space is not decreasing. The administrator suspects that the space is not being reclaimed. What is the most likely cause, and what should the administrator do?

   • AThe volume has snapshots that are consuming space; delete the snapshots.
   • BThe volume is thick-provisioned; convert it to thin provisioning.
   • CThe host is not issuing SCSI UNMAP commands; enable automatic reclamation on the volume.
   • DThe volume is too small; expand it to allow reclamation.

   A company has a critical application that requires a minimum of 10,000 IOPS. The storage administrator has created a QoS policy with a maximum of 10,000 IOPS and applied it to the application's volume. However, the application is experiencing performance issues, and the administrator suspects that the QoS policy is too restrictive. What should the administrator do?

   • ACreate a new QoS policy with a lower maximum IOPS.
   • BIncrease the QoS policy's maximum IOPS to a higher value.
   • CRemove the QoS policy from the volume.
   • DExpand the volume to increase its IOPS capacity.
