   A company is consolidating storage for two departments. Department A requires low latency and high throughput for a database, and the servers are in the same rack as the storage. Department B requires connectivity over a 200-meter distance and has existing 10GbE infrastructure. The company wants to minimize costs. Which combination of host connections should be used?

   • ADirect-attach SAS for Department A and iSCSI for Department B
   • BInfiniBand for Department A and Fibre Channel for Department B
   • CiSCSI for both departments
   • DFibre Channel for both departments

   A company has an E-Series system with both FC and iSCSI connections. The FC hosts are connected to two switches, and the iSCSI hosts are on a single switch. The administrator notices that the iSCSI hosts are experiencing performance issues during peak hours. What is the most likely cause and solution?

   • AThe iSCSI traffic is competing with other network traffic; use a dedicated VLAN or separate switch.
   • BThe iSCSI hosts are using jumbo frames incorrectly; disable jumbo frames.
   • CThe iSCSI hosts are not using multipathing; configure multipathing to improve performance.
   • DThe FC hosts are consuming too much storage controller resources; limit FC traffic.
