Refer to the exhibit.
You are designing a new SAN. The existing SAN uses eight 32-port 4-Gb/s Fibre Channel switches. Two of the switches are deployed as core switches, and six switches are deployed as edge switches. Each edge switch has four ISLs to one of the two core switches. The disk array has twelve 4-Gb/s Fibre Channel ports. Each of the 84 servers has two 2-Gb/s HBA ports each. Which Cisco MDS 9000 configuration would improve performance? Select the best response.

A.
Two Cisco MDS 9222i switches, with 48-port 1/2/4-Gb/sFibre Channel line cards in each switch

B.
two Cisco MDS 9506 switches, with one 44/4-port 1/2/4/8-Gb/sFibre Channel line card in each switch

C.
two Cisco MDS 9506 switches, with one 12-port 1/2/4-Gb/sFibre Channel line card and one 48- port 1/2/4/8-Gb/s Fibre Channel line card in each switch

D.
two Cisco MDS 9513 switches, with two 48-port 1/2/4-Gb/sFibre Channel line cards in each switch
