A group of VMs is experiencing high latency on a portgroup in an ESXi host. Which option can a vSphete administrator use to move some of the VMs to another portgroup?

IP hash is a load balancing policy for NIC teaming and is not a method for moving VMs between portgroups.

Network I/O Control (NIOC) is a vSphere feature for bandwidth allocation and prioritization for different types of network traffic, but it does not facilitate moving VMs between portgroups.

vSphere vMotion allows the live migration of a running virtual machine from one ESXi host to another, or from one datastore to another, or to change the network portgroup without downtime. By performing a vMotion that includes a change of network, the administrator can move selected VMs to a different portgroup on the same or a different host, potentially mitigating latency issues.

Network Port Binding refers to how portgroups are associated with physical NICs and is not a mechanism for migrating VMs between portgroups.
