Given the above deployment descriptor fragment, which one of the following describes the behavior of this bean?
Choice 1
The bean uses a custom primary key.
Choice 2
The bean is forced to passivate after ten seconds.
Choice 3
The bean implementation class is not part of a Java package.
Choice 4
This bean may execute without a transaction context.
Choice 5
This bean is re-entrant.

The correct answer is choice 4, as the bean is deployed with transactional attribute 'Supports', which means that it MAYBE executed without transactional contexts. Choices 1 and 5 are false because they only apply to entity beans.
