A customer has a SAN consisting of two FC switches with a single 4Gb/s ISL between them. There are
six hosts attached to one switch, with an average throughput of 30MB/s each, and a single storage
subsystem port connected to the second switch at 2Gb/s. The deployment is performing poorly and
you have been tasked with identifying the possible cause. What is the cause of the degraded
performance?

A.
ISL oversubscription

B.
HBA oversubscription

C.
Switch oversubscription

D.
Target oversubscription
