1Z0-898 Exam FAQ: Before You Book Your Seat

Oracle Java EE 6 Java Persistence API Developer Certified Expert Sample Questions:

Question 1

The developer wants to override the default mappings for an embeddable class Address used by the customer entity.
The Address class is defined as follows:
@Embeddable public class Address (
private String street;
private String city;
private String country;
. . .
)
Assume that NO mapping descriptor is present. Which code segment below shows the correct way to override the default mapping for address?

A. @ AttributeOverrides ({
@AttributeOverride (name = "street", column (name = "name_STREET")),
@AttributeOverride (name = "city, column (name = "name_CITY")),
@AttributeOverride (name = "country, column (name = "name_COUNTRY")),
}}
@Embedded Address addr;
B. @AttributeOverrides ({
@AttributeOverride (name = "street", column = @Column (name = ADDR_STREET)),
@AttributeOverride (name = "city, column = @Column (name = ADDR_CITY)),
@AttributeOverride (name = "country, column = @Column (name = ADDR_COUNTRY)),
}}
@Embedded Address addr;
C. @AttributeOverrides ({
@AttributeOverride (name = "addr.street", column = @Column (name = ADDR_STREET)),
@AttributeOverride (name = "addr.city", column = @Column (name = ADDR_CITY)),
@AttributeOverride (name = "addr.country", column = @Column (name = ADDR_COUNTRY)),
}}
@Embedded Address addr;
D. @ AttributeOverrides ({
@AttributeOverride (name = "street", column = @Column (name = "name_STREET")),
@AttributeOverride (name = "city, column = @Column (name = "name_CITY")),
@AttributeOverride (name = "country, column = @Column (name = "name_COUNTRY")),
}}
@Embedded Address addr;

Question 2

An application has three entities: the mapped superclass person class entity, and the parent and child entities, which are subclasses of person.
The application has created four entity Instances:
-Person1 is a Person entity with a primary key of 50 -Parent1is a Parent entity with a primary key of 100 -Child1 is a chi id entity with a primary key of 400 -Child2 is a child entity with a primary key of 600
Caching has been enabled in the persistence unit, the persistence provider supports caching, and none of entities have the Cacheable annotation applied, or a cacheable XML element in persistence.xml.
The application executes the following code:
Cache cache = . . . ;
Cache.evict(person.class)
Boolean result = cache.contains (Child.class, 400);
Assume there is no concurrent activity involving the cache. Which two statements are correct? (Choose two)

A. Only person1 will be removed from cache.
B. Person1, parent1, child1, and child2 will be removed from cache.
C. Result is true
D. Result is false

Question 3

A developer wants to write a type-safe Criteria API query. Which two of the following statements true about Criteria query roots? (Choose two)

A. The query MUST define a query root.
B. The query MUST define a query root only if it navigates to related entities.
C. The query MUST NOT define multiple query roots.
D. The query may define multiple query roots.

Question 4

A named query that sets an exclusive pessimistic on the entities returned by the query by setting the NamedQuery lockMode element to LockModeType.PESSIMISTIC_FORCE_INCREMENT. The application starts transaction and executes the query.
Which of the following statements is correct about the entities returned by the query?

A. Only the current transition may modify or delete the entity instances.
B. The current transaction may NOT modify or delete the entity instances.
C. Other concurrent transactions may modify but MAY NOT delete the entity instances.
D. Other concurrent transactions may modify or delete the entity instances.

Question 5

If a Persistence application locks entity x with a LockModeType.OPTIMISTIC_FORCE INCREMENT lock type, which statement is true?

A. LockModeType.OPTIMISTIC_FORCE_INCREMENT is the synonym of the LockModeType.WRITE lock type.
B. The Persistence application must increment the version value prior to locking the entity.
C. This operation will result in a PersistentLockException for a non-versioned object.
D. This operation will result in a PersistentLockException if the version checks fail.
