   A Dell midrange array uses iSCSI backend connectivity. The administrator wants to optimize performance by reducing latency. Which configuration is a best practice?

   • AEnable jumbo frames on the iSCSI VLAN.
   • BIncrease the number of iSCSI sessions to each target.
   • CUse a dedicated network for iSCSI traffic with no other traffic.
   • DPlace iSCSI traffic on the same network as front-end traffic to reduce cabling.

   A Dell midrange storage system uses SAS backend connectivity. The administrator is adding a second expansion enclosure and wants to ensure that both enclosures are connected with proper redundancy. What is the recommended cabling topology?

   • AConnect each enclosure to both controllers using separate SAS cables.
   • BDaisy-chain the enclosures from a single controller port.
   • CUse a single SAS cable from controller A to the first enclosure and from controller B to the second enclosure.
   • DConnect the first enclosure to controller A and the second to controller B, then link the enclosures together.

   When implementing Fibre Channel (FC) backend connectivity in a Dell Midrange storage system, what is a best practice for zoning?

   • AUse a separate zone for every individual disk drive
   • BUse a single zone that includes all storage controllers and disk enclosures
   • CZone each storage controller port to the specific disk enclosures it needs to access
   • DDisable zoning entirely to reduce latency

   A Dell midrange array with dual controllers is experiencing intermittent backend connectivity issues. The administrator notices that when one FC switch is rebooted for maintenance, some disks become unavailable even though the other switch is still operational. The zoning configuration appears correct. What is the most likely cause?

   • AThe FC cables are too long, causing signal degradation.
   • BBoth controllers are connected to the same FC switch, creating a single point of failure.
   • CThe disk enclosure is not powered redundantly.
   • DThe backend ports are not zoned correctly, causing traffic to be blocked.

   What is a key benefit of using dual controllers in a Dell Midrange storage system for backend connectivity?

   • AIt allows the storage system to connect to more host servers
   • BIt eliminates the need for backend cabling
   • CIt doubles the amount of storage capacity available to hosts
   • DIt provides redundancy so that if one controller fails, the other can continue serving I/O
