Question
Refer to the Exhibit. An administrator is changing the settings on a vSphere Distributed Switch (vDS). During this process, the ESXi Management IP address is set to an address which can no longer communicate with the vCenter Server. What is the most likely outcome of this action?
Options
- AThe host will disconnect from the vCenter Server and remain disconnected.
- BThe host will automatically detect the communication issue and revert the change.
- CThe host will stay connected with the change, but show an alert.
- DThe host will disconnect and migrate the vDS portgroup to a standard switch.

Why each option
The vSphere Distributed Switch rollback feature automatically detects and reverts network configuration changes that would cause an ESXi host to lose management connectivity to vCenter Server.
The host will not remain permanently disconnected because the vDS rollback feature is specifically designed to detect this condition and restore the prior configuration automatically.
The vDS rollback mechanism is a built-in safeguard that monitors management network connectivity after any configuration change is applied to the distributed switch. If the ESXi host loses contact with vCenter Server as a result of the change, the host agent automatically reverts the vDS configuration to the last known good state, restoring connectivity. This prevents administrators from permanently locking themselves out of host management via misconfigured network settings.
The host will not remain in a broken connectivity state showing only an alert; rollback actively undoes the problematic change rather than tolerating a loss of management access.
vDS does not automatically migrate port groups to a standard switch on connectivity loss; it uses rollback to restore the previous distributed switch configuration instead.
