Statechart and Activity Modeling

1. What does an entry action of a state indicate?

Action performed after the system moves into the given state

Action performed before system moves into the given state

An optional action performed when system moves into the given state

None of the above

2. What does the guard condition depicted over the transition between any two states indicate?

A condition that must be true for the transition to happen

A condition that must be false for the transition to occur

An indicator that this transition should not happen

An event that might happen as result of the transition

3. A state can contain one or more sub-state(s) within it

True

False

4. What does forking of several activities from a synchronization point indicate?

All those activities should get executed one after another

The activities can be performed in parallel

One or more activities could be skipped

5. A decision point in an activity diagram is a control where

Multiple parallel activities merge

Decision is taken whether a transition should happen

A condition is checked and decided which activity should be performed next

There is no such control
