   A university IT team is designing a SAN for two research groups that require strict isolation from each other, but they want to share the same physical Fibre Channel switches to reduce cost. They also need to ensure that a failure in one group's fabric does not affect the other. What should they implement?

   • ADeploy two separate physical fabrics, each with its own switches, and connect each group to one fabric.
   • BConfigure two VSANs on the same physical switches, and connect each group's devices to ports assigned to their respective VSAN.
   • CUse a single VSAN with two zones, and rely on the zones to provide isolation and fault containment.
   • DCreate a single fabric with a single VSAN, and use LUN masking on the storage arrays to isolate the groups.

   A service provider is building a multi-tenant SAN. They have a pair of Fibre Channel switches in each of two data centers. They want to offer each tenant a private, isolated SAN with redundant paths, but they want to minimize the number of physical switches. What is the most efficient design?

   • AUse a single VSAN for all tenants, and use port-based zoning to isolate them.
   • BDeploy a separate pair of switches for each tenant.
   • CUse a single fabric with zones for each tenant, and rely on the storage array's LUN masking for isolation.
   • DUse VSANs to create a separate logical fabric for each tenant, and connect the switches in each data center with ISLs that carry all VSANs.

   A company is experiencing poor performance on their iSCSI SAN. The network team has already confirmed that the switches support jumbo frames. The storage team wants to improve throughput for large block transfers. What is the most effective configuration change?

   • AIncrease the iSCSI session queue depth on the initiator to 256.
   • BEnable flow control on the switches and NICs to prevent packet loss.
   • CEnable jumbo frames (MTU 9000) on all iSCSI VLAN interfaces, including the storage controllers, switches, and server NICs.
   • DConfigure the iSCSI targets to use a smaller block size to reduce latency.
