Your Answer for Question 1:
The circuit may not behave as expected because of flip flops' "clk-to-q" delay. However, if the input data d is stable for a long enough period and the clock is not alternating too fast between 1 and 0, the circuit will behave properly. So, depending on the input and the clock signals, the circuit will behave accordingly.


Your Answer for Question 2:
Three distinct contexts: 
- ATM machine is considered a finite state machine since it has a certain number of inputs (card number, pin...), outputs (check card number, dispense cash..), and states (idling, processing withdrawing, dispensing cash, taking in deposit...)
- Similiarly, a parking meter is also a finite state machine.
- Thirdly, a telephone switching system.
