1.
Why there is a need to “Check that transitions to several concurrent sub-states go through a fork”?
Answer: Option 'B'
It is illegal to transition directly to more than one sub-state of a concurrent composite state without going through a fork
2.
What is a Synch state?
Answer: Option 'C'
All of the mentioned
3.
Which of the following are the ways to make transitions into and two ways to make transitions from concurrent composite states?
Answer: Option 'C'
All of the mentioned
4.
Which of the following represents history state?
Answer: Option 'D'
The history state indicator is a circled capital H and rest all are true.
5.
Which of the following are the ways to leave concurrent composite states?
Answer: Option 'C'
All of the mentioned
6.
What does “Designate an initial state in every concurrent region of a concurrent composite state” mean?
Answer: Option 'D'
If there are no transitions to a concurrent composite state’s boundary, then concurrent regions do not need to have initial states and a transition to the composite state’s boundary could be added later, though, so initial states for each region should always be specified.
7.
Which of the following are the heuristics for the State diagram?
Answer: Option 'D'
All of the mentioned
8.
Which of the following is false about Concurrent composite states?
Answer: Option 'D'
None of the mentioned
9.
Which of the following states about concurrent region?
Answer: Option 'C'
All of the mentioned
10.
What is the Transition junction point?
Answer: Option 'A'
The transitions from different sources can converge to a point and transitions leaving the point symbol may disperse to different targets
