Which storage system combination is supported in a 4-node cluster?
The correct answer is D. A pair of FAS6280s and a pair of FAS3240s. NetApp 4-node clusters require that each HA pair consist of identical controllers, and mixed platform clusters are only supported when combining two compatible HA pairs from the same generation or supported mixing matrix.

Why each option
NetApp 4-node clusters require that each HA pair consist of identical controllers, and mixed platform clusters are only supported when combining two compatible HA pairs from the same generation or supported mixing matrix.
The FAS3270 and FAS3020 are from different performance tiers and generations; NetApp does not support mixing these platforms even as separate HA pairs in the same cluster.
A cluster cannot contain a mismatched HA pair - pairing a FAS3240 with a FAS6240 as a single HA pair is unsupported because HA partners must be identical controller models.
E-Series (E7900) systems run E-Series SANtricity OS and cannot be combined into the same ONTAP cluster as FAS systems; they are architecturally separate product lines.
A pair of FAS6280s and a pair of FAS3240s is a supported combination because each pair is a matched HA pair of identical controllers, and NetApp's Hardware Universe validates this cross-family pairing in a 4-node cluster as a supported mixed configuration.
