The oncall system administrator has made a change on the ESXi host requiring a restart of the

Which action should the administrator take to restart the management network?

Use the vSphere client to enable local authentication services, then logon directly to the ESXi
Shell and run services mgmt-vmware restart.
B.
Use an SSH client to logon to the command line and run services mgmt-vmware restart.
C.
Use the vSphere client to enable the DCUI and then logon to the ESXi Shell and use the menu
to restart the management network.
D.
Logon directly to the DCUI and use the menu to restart the management network.

How can you use the DCUI if lockdown mode is enabled?
Can you use DCUI directly from the host (physically).
Obvious that from the SSH connection you cannot launch the “dcui command.
Users can be assigned DCUI access privileges explicitly via the DCUI Access advanced configuration option. The option has DCUI.Access as the key, and a comma-separated list of ESXi users as the value. Users in the list which can access the DCUI at any time, even if these users are not administrators (Admin role), and even when the host is in lockdown mode.
