  B. Use network ports as access ports only.
  C. Use multiple VLANs to segregate iSCSI traffic from other traffic types
  D. Use a single VLAN to consolidate all data traffic on the switches.
  A. Use a larger MTU size at the SAN connection rather than the host connections to allow for greater SAN bandwidth.
