An organization has deployed a high-performance full-mesh SAN using Cisco MDS 9000 Series Switches.

Each requirement identifies one element of Option B. Solid-state drives have no rotating platters or mechanical seek operation, so they eliminate rotational latency and provide the media characteristic demanded by the workload. RAID 5 stripes data and distributes one parity block across the member disks. It therefore matches the explicit requirement for striping with single parity; RAID 6 uses dual parity and would violate that condition even though it provides greater disk-failure protection. At the fabric layer, Fabric Shortest Path First is the standard Fibre Channel path-selection protocol used by Cisco MDS switches. Cisco documents that FSPF dynamically calculates the shortest and quickest path between switches, supports multiple paths, and computes an alternative route when a link fails. In a full-mesh SAN, that behavior lets the fabric select optimal routes and reconverge instead of depending on manually fixed paths. Disabling FSPF would remove the dynamic path-computation function required by the question. Options A and D also specify HDDs, which retain rotational and seek latency. Option C correctly selects SSDs and FSPF but uses RAID 6, whose two parity sets do not meet the single-parity design. Consequently, SSD media satisfies the latency goal, RAID 5 supplies striped single parity, and FSPF supplies dynamic optimal-path selection and failure recovery. All three elements must be present, making Option B the only complete design. Cisco MDS FSPF configuration guide
