Which controller option the mapping of an entire MX5016s to multiple compute sleds?
The correct answer is B. HBA330 only. Option B is correct because the HBA330 operates in pass-through (non-RAID) mode, which allows the entire MX5016s storage sled to be mapped across multiple compute sleds simultaneously - a capability that requires a host bus adapter rather than a traditional RAID controller.

Explanation
Option B is correct because the HBA330 operates in pass-through (non-RAID) mode, which allows the entire MX5016s storage sled to be mapped across multiple compute sleds simultaneously - a capability that requires a host bus adapter rather than a traditional RAID controller.
The PERC H730 (options A and D) is a RAID controller that takes exclusive ownership of attached drives, making it incompatible with shared, multi-sled mapping; this eliminates both A and D. The H745 Jumbo PERC (option C) is a fabricated product name and does not exist in Dell's controller lineup - a classic distractor designed to confuse test-takers who may conflate it with the real H745.
Memory tip: Think "HBA = Hand it off to many" - an HBA (Host Bus Adapter) passes storage through without owning it, while a PERC controls it exclusively like a RAID boss. If a question mentions sharing an entire storage sled across multiple compute nodes, the answer will always be an HBA, never a PERC.
