During a recent training exercise in a non-production environment, I built a Cisco ISE virtual server using VMware vSphere and succeeded troubleshooting an issue, which demonstrates the value of this type of exercise. It also shows how important it is for network engineers to have clear priorities and keep their eye on the goals set for the task at hand.
In this exercise, the build of the virtual server gave me the option of using one of two datastores that we’ll call Datastore One and Datastore Two. It also provided the option of choosing from multiple ESXI host machines to launch the virtual server on, and we’ll designate them with letters such as Host A, Host B, etc. Some of the hosts could associate only with Datastore One, and the rest could associate only with Datastore Two.
