2V0-621 Question #47: Real Exam Question with Answer & Explanation
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.
Explanation
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.
Common mistakes.
- A. Permanent disconnection does not occur because the rollback feature is specifically designed to prevent this outcome when management connectivity is disrupted.
- C. 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.
- D. The vDS does not automatically migrate portgroups to a standard switch; that would require manual intervention from an administrator.
Concept tested. vSphere Distributed Switch rollback for management network changes
