   • AConfigure the MTU to 9000 on storage VLANs
   • BSet the MTU to 1500 on all storage ports
   • CDisable flow control on storage-facing ports

   A media company is deploying a Dell PowerVault ME5 for video editing. The network team has configured the switches with jumbo frames and disabled flow control. However, they are seeing low throughput for large file transfers. The workload is characterized by large block (1MB) I/O. What is the most likely cause of the low throughput, and what Dell best practice should be applied?

   • AThe switch is using cut-through switching; enable store-and-forward switching to improve throughput.
   • BThe jumbo frames are causing fragmentation for large I/Os; disable jumbo frames for the storage VLAN.
   • CThe TCP window size is too small; increase the TCP window size on the hosts and storage array.
   • DThe flow control being disabled is causing packet drops; re-enable flow control to improve throughput.

   What is a Dell best practice for front-end connectivity to a midrange storage system to ensure high availability?

   • AUse a single high-speed port for all hosts
   • BConnect all hosts to the same storage controller for consistency
   • CConnect each host to a different storage controller
   • DUse only one type of connectivity (e.g., Fibre Channel only)

   According to Dell best practices, how should front-end ports be configured on a midrange storage system to maximize performance and reliability?

   • AUse all available front-end ports for a single host connection
   • BConnect hosts to multiple front-end ports and use multipathing software
   • CDisable unused front-end ports to reduce power consumption
   • DConnect each host to a single front-end port to simplify configuration

   A research institute is deploying a Dell PowerStore array for a high-performance computing (HPC) workload. The network team has configured the switches with jumbo frames and disabled flow control. However, they are seeing high latency for the NFS traffic. The workload is characterized by many small files being read and written. What is the most likely cause of the high latency, and what Dell best practice should be applied?

   • AThe jumbo frames are causing delays for small files; disable jumbo frames for the NFS VLAN.
   • BThe flow control being disabled is causing retransmissions; re-enable flow control to reduce latency.
   • CThe small file workload is causing a high packet rate; enable NFS over RDMA (if supported) to reduce latency.
   • DThe switch is using store-and-forward switching; enable cut-through switching to reduce latency.
