A vendor has released an update pack for the virtualization servers used by a company. The systems administrator has been directed to deploy the update pack following proper change management procedur

Installing the update pack on a test virtualization cluster is the critical initial step in a change management process, allowing administrators to evaluate the update's impact, identify potential issues, and ensure compatibility without affecting production services. This minimizes risk before deployment to the live environment.

Notifying clients to conduct testing typically occurs after the update has been installed and initially verified in a test environment, not as the first step.

Confirming proper operation of production servers happens after the update has been successfully deployed to the production environment, which is much later in the change management cycle.

This choice is a duplicate of option A, confirming that installing on a test cluster is the correct initial action.
