   A Dell midrange storage array is being deployed with FC backend connectivity. The environment has a mix of 8 Gbps and 16 Gbps FC switches. The administrator wants to optimize performance while maintaining redundancy. What is the best practice?

   • AUse the 8 Gbps switches for backend and 16 Gbps for front-end to balance load.
   • BStandardize on a single link speed for all backend connections to avoid performance mismatches.
   • CConnect each controller to both a 16 Gbps and an 8 Gbps switch, ensuring paths are spread across both speeds.
   • DConnect all backend ports to the 16 Gbps switches to maximize throughput.

   A Dell midrange storage system has dual controllers and uses both FC and SAS backend connectivity. The administrator wants to ensure high availability for the backend. What is a best practice?

   • AUse only one type of backend connectivity to simplify management.
   • BConnect all FC devices to controller A and all SAS devices to controller B.
   • CEnsure that each controller has redundant paths to all backend devices, regardless of the connectivity type.
   • DUse a single path from each controller to the backend to reduce cabling.
