   After exiting maintenance mode on an SDS node, the administrator notices that the node is in a 'Normal' state, but the storage pool shows 'Rebuilding'. What does this indicate?

   • AThe node is back online, and PowerFlex is rebuilding data to restore full redundancy.
   • BThe node's data was lost during maintenance and needs to be restored from backup.
   • CThe node is still in maintenance mode and needs to be exited again.
   • DThe storage pool has a hardware failure that needs immediate attention.

   A PowerFlex cluster has 4 SDS nodes with 2-copy data protection. An administrator needs to perform a rolling upgrade of all nodes. The upgrade requires rebooting each node. What is the correct approach to minimize the risk of data unavailability?

   • AUpgrade nodes without maintenance mode to speed up the process.
   • BUpgrade two nodes at a time to reduce the total upgrade time.
   • CUpgrade nodes one at a time, placing each in maintenance mode, and exit maintenance mode before moving to the next node.
   • DPlace all nodes in maintenance mode simultaneously, then upgrade them all.

   A PowerFlex cluster is experiencing a high rate of background rebuild activity. An administrator needs to perform a non-disruptive firmware update on a single SDS node. What is the primary benefit of using maintenance mode for this task?

   • AIt automatically migrates all data from the node to other nodes.
   • BIt speeds up the firmware update process by prioritizing the node's I/O.
   • CIt prevents the node from being marked as failed and avoids triggering a rebuild.
   • DIt allows the administrator to update the node without needing to reboot it.

   An SDS node is in maintenance mode for a planned upgrade. During the maintenance, the node's operating system crashes and the node becomes unreachable. What should the administrator do?

   • AIgnore the crash and continue with the maintenance plan.
   • BImmediately exit maintenance mode to allow the cluster to rebuild the node's data.
   • CAttempt to recover the node's OS, then exit maintenance mode and verify the node is healthy.
   • DRemove the node from the cluster and re-add it after recovery.

   A PowerFlex cluster uses 2-copy data protection. An administrator places one SDS node into maintenance mode. What is the expected impact on the cluster's data availability?

   • AData availability is maintained, but performance is degraded for all storage pools.
   • BData remains available, but the cluster has reduced redundancy for the data on that node.
   • CData availability is lost for the storage pools on that node.
   • DData remains available with full 2-copy redundancy.
