What configuration minimizes licensing costs when using DRS for a VM bound by a licensing agreement?

The correct choice focuses on minimizing licensing costs when using Distributed Resource Scheduler (DRS) for a virtual machine that is subject to a licensing agreement. Creating a 'Must run Virtual Machines to Hosts' affinity rule ensures that specific VMs will always run on designated hosts that comply with the licensing requirements. By using this method, you can control which hosts are utilized for these VMs, thus adhering to licensing restrictions and avoiding unnecessary costs that might arise from running VMs on non-compliant hosts.

In scenarios where cost savings through compliance are essential, this affinity rule is particularly beneficial as it guarantees that the VMs will always operate on hosts that are covered by the appropriate licenses, therefore minimizing the risk of overstepping licensing agreements which might incur additional fees.

Other rules, like dependency rules or affinity and anti-affinity rules, do not offer the same level of control suitable for compliance with licensing agreements. Focusing on where the VM must run ensures adherence to licensing requirements, making it the most cost-effective and administratively sound choice in this context.
