Correct Answer: AC

Industry Standard Architecture – Student Guide 1 – Page 295
Fat trees and skinny trees are two types of backbone SAN topologies. The main difference between fat and skinny trees is the number of ISLs used to connect the edge switches to the backbone switches. The number of ISLs subtracts from the number of end ports and affects the total number of switches needed for a particular configuration. Fat trees use half the number of edge switch ports as ISL connections; skinny trees use less than half.
