As is drawn there can be no voltage measured across the switch that is indicating 120 volts across it. If this is a troublshooting question and the drawing is representing what you are supposed to have - then there will be 120 volts measured across that switch if there is a ground fault on the "load side" conductor connected to the switch. Otherwise if there are no faults and everything is installed as drawn and in state shown in the drawing (open vs closed contacts) there should be no voltage to measure across that switch.
Since this is a training thing, there is either a mistake or we don't fully understand what the circumstances are supposed to be when this measurement is taken.
