Explanation
Second-generation Cisco MDS directors (high-end SAN switches) provide fully redundant components including redundant supervisors, power supplies, and fabric modules (B), ensuring no single point of failure. They achieve 100 percent port efficiency (C), meaning every front-panel port can be used for host or storage connectivity - no ports are wasted on internal inter-blade connections since the switching fabric is internal. In a collapsed core design, ISLs (Inter-Switch Links) between blades/line cards are contained within the single chassis (D), eliminating the need for external cabling between separate switches. Choice A is incorrect - a collapsed core with a director does not inherently provide a higher fan-out ratio than a distributed design. Choice E is incorrect - MDS directors provide lower latency and higher throughput, not higher latency.
