Given point-to-point, bus, loop and Fabric topologies, which solution would be considered a mixed
topology approach using three separate but interconnected topologies?

A.
AFibre Channel-based storage network using Fabric switches with both loop attached and
point-to-point attached servers and storage

B.
A cluster of servers connecting to Ethernet switches with a combination NAS Gateway Object
storage system for file sharing and block access

C.
A mixed Serial ATA (SATA) and Serial Attached SCSI (SAS) solution using expanders where
the SATA disks and the SAS disks share connectivity to the expanders

D.
An Ethernet-basediSCSI storage network using Ethernet hubs connected to Ethernet switches
with the storage devices directly attached to switches and the servers connected to hubs
