   A Dell PowerEdge XE server is running a high-performance computing (HPC) workload. The administrator observes that the CPU utilization is at 100% for all cores, but the memory utilization is only 50%. The workload is completing, but slower than expected. What does this indicate?

   • AThe storage is the bottleneck, causing the CPU to wait
   • BThe network is the bottleneck, causing the CPU to work harder
   • CThe CPU is the bottleneck, and the workload is CPU-bound
   • DThe memory is the bottleneck, and the workload is memory-bound
