   A bank is upgrading the OS on its Dell midrange storage array. The array is part of a two-node cluster. After upgrading the first node, the cluster fails over to the second node. What should the administrator do next?

   • AUpgrade both nodes simultaneously to avoid a second maintenance window.
   • BVerify that the first node is healthy and the cluster is stable before upgrading the second node.
   • CProceed to upgrade the second node immediately to complete the upgrade quickly.
   • DFail back to the first node to test its functionality before upgrading the second node.

   A financial services firm is deploying a Dell midrange storage array in a two-node cluster for a critical trading application. The application requires low latency and high availability. The storage team is deciding between an active/passive and an active/active cluster configuration. Which configuration should they choose to meet the application's requirements?

   • ASingle controller configuration to avoid cluster complexity and reduce latency.
   • BActive/passive cluster with one node serving all I/O and the other node on standby.
   • CActive/active cluster where both nodes serve I/O simultaneously, with automatic failover if one node fails.
   • DCluster with one node dedicated to reads and the other to writes, with no failover.
