   A database administrator is deploying a PowerEdge R750 server for an OLTP database. The database requires high IOPS and low latency for transaction processing. The administrator plans to use a PERC H755 controller. Which drive configuration will best meet the database's performance requirements?

   • AA RAID 5 array of 7200 RPM SATA HDDs, because it provides good capacity and redundancy.
   • BA RAID 0 array of 10K RPM SAS HDDs, because it provides the highest write performance.
   • CA RAID 6 array of NVMe SSDs, because it provides the highest capacity and dual-drive fault tolerance.
   • DA RAID 10 array of SATA SSDs, because it provides high IOPS, low latency, and redundancy.

   A PowerEdge R740xd server is being configured with 24 2.5-inch drives. The administrator connects the backplane to a PERC H740P controller using two SAS cables. The server will run a virtualization platform. What is the primary purpose of connecting the backplane to the PERC controller with these cables?

   • ATo provide a network connection for remote drive management.
   • BTo provide power to the drives through the PERC controller.
   • CTo enable the PERC controller to communicate with the drives and manage the RAID arrays.
   • DTo allow the backplane to control the RAID functionality independently.

   A Dell PowerEdge server needs to store a large amount of infrequently accessed data at the lowest possible cost. Which storage type is the most appropriate?

   • AHDDs, because they offer lower cost per gigabyte for large capacities
   • BNeither, because servers cannot store infrequently accessed data
   • CA mix of SSDs and HDDs, because it always reduces cost
   • DSSDs, because they are faster and more durable
