   A maintenance team is planning to replace a failed node in a PowerScale cluster. The replacement requires a brief shutdown of the node, which will reduce cluster capacity by 25%. The cluster is currently running at 80% capacity. What should the maintenance plan include to minimize risk?

   • ANotify all users to stop accessing the cluster during the maintenance window.
   • BIncrease the cluster's replication factor to 3 before the maintenance to ensure data safety.
   • CSchedule the maintenance during a period of low usage and verify that the cluster can tolerate the reduced capacity.
   • DPerform the maintenance immediately without scheduling, as the node replacement is urgent.
