Explanation
Option B (4 nodes) is correct because a PowerFlex cluster requires a minimum of 4 nodes to achieve a supported, fault-tolerant configuration - this ensures data can be distributed with adequate redundancy so the cluster survives a single node failure while maintaining quorum and data accessibility.
Option A (3) is wrong because, while 3 nodes can satisfy the MDM (Metadata Manager) quorum requirement alone, 3 nodes are insufficient to meet PowerFlex's minimum supported deployment for a complete, production-ready cluster with proper data protection.
Options C (6) and D (8) represent larger deployments that exceed the minimum; they're valid cluster sizes but aren't the minimum threshold the question asks for.
Memory tip: Think "4 wheels on a car" - just like a car needs all 4 to drive safely, PowerFlex needs at least 4 nodes to roll out a supported, resilient cluster. If you see "3," remember that's the MDM quorum number, not the full cluster minimum.
