   A data center technician is installing a new PowerEdge R750 server. The server has a backplane that supports both SAS and SATA drives. The administrator plans to use a mix of SAS HDDs and SATA SSDs in the same server. What is the primary consideration when connecting these drives to the PERC controller?

   • AThe server must be powered off when connecting the backplane to the PERC controller.
   • BThe PERC controller must support both SAS and SATA drives, and the backplane must be connected to the controller with the appropriate cables.
   • CThe backplane must be configured to support only one drive type at a time.
   • DSAS and SATA drives cannot be mixed in the same RAID array.

   A company is configuring a new PowerEdge R650 server with eight 2.4TB SAS HDDs. The administrator needs to create a single logical volume that provides both high performance and protection against the failure of any one physical drive. The server has a PERC H755 controller. Which RAID level should the administrator configure on the PERC to meet these requirements?

   • ARAID 6, because it provides protection against two simultaneous drive failures and is the fastest option.
   • BRAID 5, because it stripes data and parity across all drives, offering good performance and protection against a single drive failure.
   • CRAID 0, because it stripes data across all drives for maximum performance and uses the full capacity.
   • DRAID 1, because it provides a mirror of the data, offering the highest level of protection.
