   An administrator is troubleshooting storage performance issues on a cluster. The storage array is reporting high latency, and VMs on the same datastore are experiencing inconsistent performance. The admin suspects that one VM is causing the issue by generating excessive I/O. What is the primary purpose of enabling Storage I/O Control (SIOC) on the affected datastore?

   • ATo increase the throughput of the storage array by optimizing the I/O queue depth.
   • BTo set a hard limit on the total I/O that can be sent to the storage array.
   • CTo prioritize I/O for critical VMs and ensure fair distribution of I/O among all VMs during storage contention.
   • DTo automatically migrate VMs to a different datastore when latency is high.

   A vSphere administrator is configuring SIOC on a datastore that hosts a mix of production and test VMs. The production VMs are critical and must not be starved of I/O. The test VMs are less critical and can tolerate lower performance. The storage array is prone to latency spikes. What is the best way to configure SIOC to protect the production VMs?

   • AEnable SIOC, set the congestion threshold to 30 ms, and assign production VMs 'High' storage I/O shares and test VMs 'Low' shares.
   • BEnable SIOC and set a storage I/O limit of 100 IOPS on the test VMs.
   • CEnable SIOC and set the congestion threshold to 100 ms to ensure SIOC only activates during severe latency.
   • DAssign production VMs 'High' storage I/O shares without enabling SIOC.
