   A PowerFlex cluster has 6 SDS nodes with 2-copy data protection. An administrator needs to replace a failed power supply in one node. The replacement requires a 30-minute power-off. The cluster is currently at 100% capacity. What is the primary risk during this maintenance?

   • AThe cluster will automatically rebuild data from the node in maintenance mode.
   • BThe cluster will run out of storage capacity during the maintenance.
   • CIf another node fails during the 30-minute window, data may become unavailable.
   • DThe cluster will experience a performance degradation for all storage pools.
