Q91.
What does “Designate an initial state in every concurrent region of a concurrent composite state” mean?

a.

If there are no transitions to a concurrent composite state’s boundary, then concurrent regions do not need to have initial states

b.

A transition to the composite state’s boundary could be added later, though, so initial states for each region should always be specified

c.

It is legal to transition directly to more than one sub-state of a concurrent composite state without going through a fork

d.

All of the mentioned

Discuss
Answer: (d).All of the mentioned
Q92.
Why there is a need to “Check that transitions to several concurrent sub-states go through a fork”?

a.

State diagrams must specify deterministic finite automata, so there can be no doubt which transition to follow under every possible circumstance

b.

It is illegal to transition directly to more than one sub-state of a concurrent composite state without going through a fork

c.

All of the mentioned

d.

None of the mentioned

Discuss
Answer: (b).It is illegal to transition directly to more than one sub-state of a concurrent composite state without going through a fork
