An administrator runs third-party software in a virtual machine (VM). The third-party licensing agreement requires payment of a license fee for each host to which the VM migrates.
How can the administrator configure Distributed Resource Scheduler (DRS) to minimize licensing costs?
To minimize licensing costs, the administrator should create a 'Must run Virtual Machines to Hosts' affinity rule. This rule ensures that the specified virtual machine runs only on designated hosts, which helps to control and limit the number of hosts to which the VM may migrate, thereby reducing the license fees incurred.
'Must' because if the host crashes, then HA can still power ON the VM in another host. (Will have to pay for extra license). If 'should' is given, then VM will not power ON in another host, and it will be powered OFF until the same host is restarted.
Also should have the VM to Host affinity rule
