CTFL Exam - Question 29

For test case (i) X-Z-V-W, the correct state transitions are S1 – S2 – S3 – S4 – S4. Starting at S1, transition X takes us to S2, then transition Z takes us to S3, transition V takes us to S4, and transition W cycles back to S4. For test case (ii) W-Y-U-U, the correct state transitions are S2 – S4 – S4 – S4 – S2. Starting at S2, transition W takes us to S4, transition Y takes us to S4 again, transition U stays at S4, and the last transition U also stays at S4. Thus, option B is correct.
