   A hospital is implementing a new SAN. They have two Fibre Channel switches and two storage controllers. Each server has two HBAs. The hospital wants to ensure that if one switch fails, the server can still access storage, and that the two departments (radiology and cardiology) cannot see each other's storage. What is the best zoning design?

   • ACreate a zone per switch that includes all devices connected to that switch, and rely on the storage array's LUN masking for isolation.
   • BCreate a single zone per department that includes all HBAs and both controllers, and configure it on both switches.
   • CCreate two zones per department, one on each switch, and include the department's server HBA WWPNs and both storage controller WWPNs in each zone.
   • DUse port-based zoning on each switch, assigning each department's ports to a separate zone, and enable soft zoning.

   What is the primary purpose of Fibre Channel zoning?

   • ATo combine multiple physical links into one logical link
   • BTo control which initiators can see and communicate with which targets
   • CTo assign IP addresses to Fibre Channel ports
   • DTo increase the available bandwidth of the fabric

   A company is deploying NVMe-oF over RoCE for a high-performance database. They have two storage controllers and two switches. The network team wants to ensure low latency and high availability. What is the best configuration?

   • AEnable flow control on the switches and NICs, but do not configure a separate VLAN.
   • BUse a dedicated VLAN for NVMe-oF traffic, enable PFC (Priority Flow Control) on the switches, and configure the servers with two NICs, each connected to a different switch.
   • CUse the same VLAN as the LAN, but enable jumbo frames on all devices.
   • DConfigure the servers with a single NIC and rely on the storage controller's active-active failover.

   A storage administrator is troubleshooting performance issues on an iSCSI SAN. The network team has confirmed that jumbo frames are enabled on all switches and NICs. The administrator notices that the iSCSI initiator's queue depth is set to 32, and the storage array's queue depth is set to 128. What is the most likely cause of the performance issue?

   • AThe storage array's queue depth is too high, causing it to drop I/O requests.
   • BThe initiator's queue depth is too low, limiting the number of outstanding I/O requests.
   • CJumbo frames are causing fragmentation on the network.
   • DThe iSCSI session is not using CHAP authentication, causing overhead.
