A user wants to receive an email notification when the virtual machine CPU usage enters a warning state, and again when the condition has been resolved. Which two state changes must be selected to receive the appropriate notifications (Choose Two)?

A.
red-green state change

B.
yellow-green state change

C.
yellow-red state change

D.
green-yellow state change

Explanation:
VMware uses colors to denote alarm severity:
Normal green
Warning yellow
Alert red
You can set alarms to trigger when the state changes from green to yellow, yellow to red, red to yellow, and yellow to green.

When the virtual machine CPU usage enters a warning state, it will change from Normal (green) to Warning (yellow). When the condition has been resolved it will change from Warning (yellow) to Normal (green).
