   A server administrator reports that a server can see the storage LUNs but cannot perform I/O operations. The server is connected to a Fibre Channel switch, and the storage array is also connected to the same switch. The administrator has verified that the HBA is online and the zoning is correct. What is the next step to diagnose the issue?

   • AReplace the HBA with a known-good one.
   • BRun a ping command from the server to the storage array's management IP address.
   • CCheck the storage array's LUN masking to ensure the server's HBA WWPN is mapped to the LUNs.
   • DReboot the server to force the HBA to re-login to the fabric.

   A media company is deploying an iSCSI SAN for video editing. They have two storage controllers and multiple servers. The network team wants to ensure that iSCSI traffic is isolated from regular LAN traffic and that each server has redundant paths to both controllers. What is the best network configuration?

   • AUse the same VLAN as the LAN, but enable jumbo frames on all switches and NICs to improve iSCSI performance.
   • BCreate a dedicated VLAN for iSCSI, assign each server two NICs to that VLAN, and configure MPIO to use both paths to the storage controllers.
   • CAssign each server a single NIC to the iSCSI VLAN and rely on the storage controller's active-passive failover.
   • DConfigure the iSCSI targets with multiple IP addresses and use round-robin DNS to distribute connections.

   A server administrator reports that a new Linux server cannot see the LUNs on the E-Series storage array. The HBA is connected to a Fibre Channel switch, and the storage array is also connected to the same switch. The administrator has verified that the HBA is online and the cable is secure. What is the next step to diagnose the issue?

   • ACheck the Fibre Channel switch's zoning configuration to ensure the server's HBA WWPN is in a zone with the storage array's target WWPN.
   • BRun a ping command from the server to the storage array's management IP address.
   • CReplace the HBA with a known-good one.
   • DReboot the server to force the HBA to re-login to the fabric.
