   A scientific research organization is deploying a PowerScale cluster for a workload that involves both large sequential reads (genomic sequencing) and many small random writes (metadata updates). The network team is analyzing the workload to determine the network requirements. What is the most important factor to consider in this analysis?

   • AThe number of clients accessing the cluster, as it determines the number of connections.
   • BThe mix of sequential and random I/O patterns, as they have different network requirements.
   • CThe total amount of data to be stored, as it determines the number of nodes needed.
   • DThe operating system of the clients, as it determines the protocol to use.

   A research lab is deploying a PowerScale cluster for large-scale genomic sequencing. The workload involves transferring very large files (100GB+) between the cluster and compute nodes over a 40GbE network. The current performance is lower than expected. Which network tuning parameter is most likely to improve throughput for this workload?

   • ADisable TCP offload to reduce CPU usage on the compute nodes.
   • BDecrease the MTU to reduce the packet size and improve reliability.
   • CReduce the number of TCP connections to avoid network congestion.
   • DIncrease the TCP window size to allow more data in flight.
