specified zone. For information about metadata, see

Only the metadata keys that you provide in the command get removed. All other

existing metadata entries remain the same.

After you remove a specific project zonal metadata entry, if that metadata key

has any project-wide value configured, then the VMs in the zone automatically
|

inherit that project-wide value.
