CompTIA Server+ SK0-005 Practice Question

A Windows Server 2022 file server uses a six-disk RAID-10 array and is monitored at 30-second intervals. During a time when users complain of slow file saves, the collected averages are:

  • CPU utilization: 42 %
  • Available memory: 6 GB of 16 GB
  • Network throughput: 150 Mb/s on a 1 Gb/s NIC
  • Average Disk Queue Length: 14

Which server subsystem is most likely the performance bottleneck?

  • The server is running out of physical memory

  • Network bandwidth on the 1 Gb/s NIC is exhausted

  • CPU capacity is maxed out

  • Disk I/O on the RAID-10 array is saturated
