Which two types of traffic are managed only by the management VDOM?

FortiGate Infrastructure 7.2 Study Guide (p.73): "What about traffic originating from FortiGate? Some system daemons, such as NTP and FortiGuard updates, generate traffic coming from FortiGate. Traffic coming from FortiGate to those global services originates from the management VDOM. One, and only one, of the VDOMs on a FortiGate device is assigned the role of the management VDOM. It is important to note that the management VDOM designation is solely for traffic originated by FortiGate, such as FortiGuard updates, and has no effect on traffic passing through FortiGate."
