The correct answer is B. The host will automatically detect the communication issue and revert the change. vSphere Distributed Switch includes a built-in rollback mechanism that automatically reverts network configuration changes that would cause an ESXi host to lose management connectivity to vCenter Server.
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
vSphere Distributed Switch includes a built-in rollback mechanism that automatically reverts network configuration changes that would cause an ESXi host to lose management connectivity to vCenter Server.
Permanent disconnection does not occur because the rollback feature is specifically designed to prevent this outcome when management connectivity is disrupted.
The vDS rollback feature monitors whether a configuration change breaks the management network path between the ESXi host and vCenter Server. If connectivity is lost after applying the change, the host detects the failure and automatically reverts to the previous working configuration, restoring the management connection without administrator intervention.
The host cannot stay connected and show an alert if the management IP change breaks the network path to vCenter - there would be no channel over which to report the alert.
The vDS does not automatically migrate portgroups to a standard switch; that would require manual intervention from an administrator.
