Each municipal rack server that runs civic virtual machines hosts a vSphere hypervisor kernel. Which vSphere component is that?
Select an answer to reveal the explanation.
Short Explanation
The kernel on the rack server is ESXi—the hypervisor that actually runs the civic VMs. vCenter manages many of those hosts, NSX Manager manages the virtual network, and a vSAN witness is a quorum appliance, not the host kernel.
Full Explanation
Each municipal rack server that runs civic virtual machines hosts a vSphere hypervisor kernel: ESXi. That kernel is the component that schedules CPU and memory and presents virtual hardware to guests on the rack, which is why operators treat ESXi as the on-host compute engine for permitting, CAD, and utility VMs. vCenter Server centrally manages many ESXi hosts and VMs; it is the management server and inventory system, not the on-host hypervisor kernel itself. NSX Manager is the management and central-control plane for the virtual network; it prepares and coordinates fabric policy but does not replace ESXi on the rack server. A vSAN witness appliance participates in stretched-cluster quorum and is not the hypervisor that runs general civic VMs on each rack server. Exam caveat: associates must separate the hypervisor (ESXi) from the management plane (vCenter) and from NSX management appliances. Diagrams that show only “vSphere” still imply ESXi on hosts plus vCenter for management. Operational check: SSH or DCUI to a rack host and confirm ESXi is the running hypervisor; use vCenter to manage that host; confirm NSX Manager and any witness VMs are separate appliances with different roles, and keep that role map in the municipal runbook.
