   A PowerEdge server is configured with a hardware RAID controller and a 10 GbE network adapter. The administrator is troubleshooting a performance issue where large file transfers from the server to a client are slow. The administrator checks the system and finds that the CPU utilization is high, and the network adapter is not saturating the link. Which component is most likely the bottleneck?

   • AThe network adapter is not fast enough to send the data.
   • BThe memory bus is saturated and cannot transfer data fast enough.
   • CThe RAID controller is not fast enough to read the data from the drives.
   • DThe CPU is spending too much time processing network packets.

   A PowerEdge server is experiencing high CPU utilization during large file transfers from a network share. The administrator suspects that the CPU is spending too much time copying data between the network adapter and memory. Which technology would most directly address this issue?

   • AEnable RDMA on the network adapter.
   • BEnable TCP offload on the network adapter.
   • CEnable interrupt coalescing on the network adapter.
   • DIncrease the number of CPU cores dedicated to the file transfer process.

   What is the primary benefit of Direct Memory Access (DMA) in a PowerEdge server?

   • AIt increases the CPU clock speed.
   • BIt allows devices to transfer data to memory without CPU intervention.
   • CIt encrypts data during transfer.
   • DIt reduces the amount of RAM needed.
