An administrator is reviewing a virtual machine's storage performance on an ESXi 6.5 host and noticed that it is affecting shared data storage activity on another host. Which should be enabled in orde

Network I/O Control manages network bandwidth allocation on virtual distributed switches and has no effect on storage I/O contention on shared datastores.

Storage I/O Control works at the datastore level and enforces I/O shares and limits across all virtual machines from all connected hosts, using a congestion threshold to detect when one VM's heavy I/O is impacting shared storage performance. When congestion is detected, SIOC redistributes I/O bandwidth fairly, directly mitigating the cross-host storage interference described in the scenario.

Storage DRS makes placement and migration recommendations for virtual machines across datastores based on capacity and latency but does not throttle real-time I/O from a specific running VM.

vSphere HA monitors host and VM availability for failover purposes and does not address storage I/O contention or bandwidth fairness between virtual machines.
