Your customer has requested a solution with HPE Alletra Storage MP B10000 that needs four...

The correct answer is C. The customer requirement is explicit: four SFP28 iSCSI ports per controller node. An HPE Alletra Storage MP B10000 controller pair has two nodes, so the design requires eight usable SFP28 optical connections in total when all four 25GbE ports on each node are to be populated. The BOM already includes the Ethernet host bus adapters required for the iSCSI personality; the gap is the number of optical transceivers. HPE Alletra Storage MP B10000 supports host-port configuration by node, and HPE QuickSpecs list host port limits by controller model. HPE also identifies the 10/25GbE 4-port Host Bus Adapter as the correct Ethernet HBA class for Alletra Storage MP connectivity, while the Q2P64B item is the 25Gb SFP28 short-wave extended-temperature optical transceiver. Option A incorrectly removes the HBAs. Option B adds unnecessary HBAs instead of completing the optics population. Option D replaces adapters unnecessarily when the correct Ethernet HBA capacity is already present. The required correction is to add the missing four SFP28 transceivers so that all eight 25GbE ports can be used for iSCSI.
