must be validated. Which option will achieve this behavior?
A. Add validation logic to the setter methods for each property.
B. Add the PrePersist callback method with all of the validation logic.
C. Add the PostPersist callback method with all of the validation logic.
D. Add PrePersist and PreUpdate callback methods with all of the validation logic.

NO.3 XYZ Software develops business components using both the EJB 2.1 and EJB 3.0 APIs. Some
customers are reluctant to completely migrate to the EJB 3.0 model, but are willing to have EJB 2.1
session beans invoke EJB 3.0 session beans.
How should XYZ Software enhance these components to meet this customer requirement?
A. Use @EJB to inject a reference to the EJB 3.0 business interface into the EJB 2.1 bean class.
B. Use <ejB. ref> in ejB. jar.xml for the EJB 2.1 bean to declare a reference to the EJB 3.0
business interface.
C. Add an EJB 3.0-style business interface to EJB 2.1 beans to achieve interoperability between EJB 2.1
and EJB 3.0 beans.
D. Use @RemoteHome and @LocalHome to adapt EJB 3.0 beans so that EJB 2.1 beans can look up the
adapted home interfaces using JNDI.

A. Access the identity information in the X.509 certificate used to authenticate the user from within
breakout.
B. Use the getCallerPrincipal method on an injected SessionContext to determine the required
information.
C. Use the isCallerlnRole method on an injected SessionContext to determine the required information.
D. Ensure that the breakout method is appropriately annotated with @RolesAllowed.

NO.10 A developer writes two session beans which cooperate. The first session bean, ShoppingCart, collects
orders and is implemented as a stateful session bean. The second session bean, CalculateDiscount, is
implemented as a stateless session bean and runs on a different server. ShoppingCart contains the
method getTotalPrice, which calculates the total price of the order in the ShoppingCart, including
discounts. Discounts are calculated by CalculateDiscount using the information on the ShoppingCart
bean, combined with data from a database. Which scenario can accomplish this?
A. The CalculateDiscount offers a method calculate which is invoked by the ShoppingCart bean passing
the this reference.
B. The CalculateDiscount offers a method calculate which is invoked by the ShoppingCart bean.
CalculateDiscount accesses the ShoppingCart instance by JNDI lookup.
C. The CalculateDiscount offers a method calculate which is invoked by the ShoppingCart bean passing
its reference obtained from the SessionContext.getBusinessObject method.
D. The CalculateDiscount offers a method calculate which is invoked by the ShoppingCart bean.
CalculateDiscount accesses the state of ShoppingCart by dependency injection.

NO.11 A stateful session bean contains a number of instance variables. The types of instance variables A and
B are NOT serializable. Instance variable B is a complex type which is populated by many business calls,
and can, therefore, NOT be refilled by the client without starting all over. A helper instance variable C is
defined as having a Serializable type, and can hold all the information which is in variable B. For example,
B is of type XML-DOM Tree and C of type String. Which two solutions, when combined, maintain the state
of the session bean over a passivation and activation by the container? (Choose two.)
A. The value of helper variable C is used to create the value of instance variable B in the beans no-arg
constructor.
B. The value of helper variable C is used to create the value of instance variable B in a
@PostCreate annotated method.
C. The value of helper variable C is used to create the value of instance variable B in a
@PostActivate annotated method
D. Instance variable A must be made null and instance variable B must be converted to a
Serializable type and assigned to another instance variable in a @PreDestroy annotated method.
E. Instance variable A must be defined transient. Instance variable B must be converted to a Serializable
type, set to null, and assigned to the instance variable C in a @PrePassivate annotated method.

NO.14 A developer is creating an entity which is mapped to a table that has a primary key constraint defined on
two character columns and would like to use mapping defaults as much as possible to simplify the code.
Which two mapping options can be chosen.? (Choose two.)
A. Use an @ld property that constructs a private field as a concatenation of two columns.
B. Use a separate class to map those two columns and use an @ldClass annotation to denote the primary
key field or property in the entity.
C. Use a separate @Embeddable class to map those two columns and use an @Embeddedld annotation
to denote a single primary key field or property in the entity.
D. Use a separate @Embeddable class to map those two columns and add two fields or
properties to the entity, each marked as @ld, that correspond to the fields or properties in the embeddable
class.
E. Use a separate class to map those two columns. Specify that class using @ldClass annotation on the
entity class. Add two fields or properties to the entity, each marked as @ld, that correspond to the fields or
properties in that separate class.
