   A PowerEdge server is experiencing high CPU utilization during network transfers. The administrator suspects that the CPU is spending too much time copying data between the network adapter and memory. The server has a 25 GbE adapter that supports RDMA. Which configuration would most effectively reduce CPU utilization?

   • AEnable RDMA and configure the application to use it.
   • BIncrease the number of CPU cores dedicated to the network stack.
   • CEnable interrupt coalescing on the network adapter.
   • DEnable TCP offload on the network adapter.

   A PowerEdge server is configured with a hardware RAID controller and multiple SSDs. The administrator wants to understand the data flow when a user reads a file from a shared folder on the server. Which sequence correctly describes the data flow from the storage to the user?

   • ASSD → Network adapter → CPU → Memory → RAID controller → User
   • BSSD → RAID controller → CPU → Memory → Network adapter → User
   • CSSD → Memory → RAID controller → CPU → Network adapter → User

   A PowerEdge server is running a large in-memory database. The administrator notices that performance degrades significantly when the database's working set exceeds the available RAM. Which part of the memory hierarchy is most likely causing the performance degradation?

   • AThe memory bus is saturated by the database's read and write operations.
   • BThe L2 cache is being thrashed by the database workload.
   • CThe server is using virtual memory and paging to disk.
   • DThe L1 cache is too small to hold the working set.
