CLAD Question #121: Real Exam Question with Answer & Explanation

When the program executes, the user presses and then releases Boolean Control with Switch Until Released mechanical action. Assuming that the starting value of Boolean Control is FALSE, what value does the Result indicator display after execution? Image description: A LabVIEW block diagram showing a While Loop. A 'Boolean Control' with 'Switch Until Released' action is wired to the loop condition terminal through a NOT gate. Inside the loop, a shift register is initialized to 0. The value '0' is also wired to the left shift register terminal. The right shift register terminal is wired to an indicator labeled '123:Result'. There is also a Flat Sequence Structure with a numeric constant 0 and a property node for 'Boolean Control::Value Change' inside it, but these do not affect the '123:Result' indicator as wired.
