   A storage administrator is configuring a new Dell midrange array with dual controllers and two FC switches. Each controller has two FC ports designated for backend connectivity. The administrator wants to ensure that a single switch failure does not cause loss of access to any disk. What is the best practice for connecting the backend FC ports?

   • AConnect both controllers to the same FC switch but use different zones for each controller.
   • BConnect all backend ports to a single FC switch and rely on the other switch for front-end traffic.
   • CConnect both ports of each controller to the same FC switch to simplify cabling.
   • DConnect one port from each controller to each FC switch, ensuring both switches are used.

   An organization is deploying a Dell midrange storage array with iSCSI backend connectivity. The network team wants to ensure high availability and performance for the iSCSI traffic. Which configuration should the storage administrator recommend?

   • AConfigure iSCSI without VLANs and rely on the physical switch to segment traffic.
   • BUse dedicated VLANs for iSCSI traffic and configure multiple paths with MPIO.
   • CUse the same VLAN as the production network to simplify management.
   • DPlace all iSCSI backend traffic on a single VLAN with multiple subnets to increase throughput.
