The developer wants to write a portable criteria query that will order the orders made by customer James Brown according to increasing quantity. Which one of the below queries correctly accomplishes that task?

• A. CriteriaBuilder cb= . . .
  CriteriaQuery<order> cq = cb.createquery<order.class>
  Root <customer, order> 0 = cq.from(customer.class);
  Join <customer, order> 0 = c.Join(customer-.orders);
  cq.where (cb.equal(c.get(customer_.name, James Brown)));
  cq.orderBy (0.get (order_.quantity));
• B. CriteriaBuilder cb= . . .
  CriteriaQuery<order> cq = cb.createquery<order.class>
  Root <customer, order> 0 = cq.from(customer.class);
  Join <customer, order> 0 = c.Join(customer-.orders);
  cq.where (cb.equal(c.get(customer_.name, James Brown)));
  cq.orderBy (0.get (order_.quantity));
  cq.select(0);
• C. CriteriaBuilder cb= . . .
  CriteriaQuery<order> cq = cb.createquery<order.class>
  Root <customer, order> 0 = cq.from(customer.class);
  Join <customer, order> 0 = c.Join(customer-.orders);
  cq.where (cb.equal(c.get(customer_.name, James Brown)));
  cq.orderBy (0.get (order_.quantity));
  cq.orderBy ("quantity");
• D. CriteriaBuilder cb= . . .
  CriteriaQuery<order> cq = cb.createquery<order.class>
  Root <customer, order> 0 = cq.from(customer.class);
  Join <customer, order> 0 = c.Join(customer-.orders);
  cq.where (cb.equal(c.get(customer_.name, James Brown))); cq.select(0);
  cq.orderBy (0.get (order_.quantity));

A session bean business method throws an exception during execution.
Which two are responsibilities of the Bean Provider when throwing the exception? (Choose two.)

• A. For application exceptions, ensure that the current transaction will commit.
• B. For checked exceptions from which the bean cannot recover, throw an EJBException that wraps the original exception.

• D. For system errors, when the client is remote through a java.rmi.remoteException that wraps the original exception.

Which EntityManager API will lock entity x with a pessimistic lock?

• A. em.lock(x, LockModeType.PESSIMISTIC_READ)
• B. em.lock(x, LockModeType.PESSIMISTIC)
• C. em.lock(x, LockModeType.WRITE)
• D. em.lock(x, LockModeType.OPTIMISTIC_FORCE_INCREMENT)

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

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

Which one of the following queries selects the customer whose order has the highest total price?

• A. CriteriaBuilder cb = ...
  CriteriaQuery<Customer> cq = cb.createquery(customer.class)
  Root<Customer> c = cq.from(Customer.class);
  Join<Customer, Order> o = c.join(Customer__.orders);
  cq.select(c).distinct(true);
  Subquery<Double> sq = cq.subquery(Double.class);
  Root<Order> subo = cq.correlate(o);
  sq.select(cb.max(subo.get(Order_.totalPrice)));
  cq.where(cb.equal(o.get(Order_.totalPrice), cb.all(sq)));
• B. CriteriaBuilder cb = ...
  CriteriaQuery<Customer> cq = cb.createQuery(Customer.class);
  Root<Customer> c = cq.from(Customer.class);
  Join<Customer, Order> o = c.join(Customer_.orders);
  cq.select(c).distinct(true);
  Subquery<Double> sq = cq.subquery(Double.class);
  Root<Order> subo = sq.from(Order.class);
  sq. select (ci: . max ( subo . get (Order_ . Total Price) ) ) ;
  cq.where(sq.all(o.gei(Order_.totalPrice)));
• C. CriteriaBuilder cb = ...
  Criteria Query <Customer> cq = cb.create Query (Customer.class);
  Root<Customer> c = cq.from(Customer.class);
  Join<Customer, Order> o = c.join(Customer__.orders);
  cq.select(c).distinct(true);
  Subquery<Double> sq = cq.subquery(Double.class);
  Root<Order> subo = cq.correlate(o);
  sq.select(cb.max(subo.get(Order_.totalPrice)));
  cq.where(cb.equal(o.get(Order_.totalPrice), cb.all(sq)));
• D. CriteriaBuilder cb = ...
  CriteriaQuery<Customer> cq = cb.cteateQuery(Customer.class);
  Root<Customer> c = cq.from(Customer.class);
  Join<Customer, Order> o = c.join(Customer__.orders);
  cq.select(c).distinct(true);
  Subquery<Double> sq = cq.subquery(Double.class);
  Root<Order> subo = cq.correlate(o);
  sq.select(cb.max(subo.get(Order_.totalPrice)));
  cq.where(cb.equal(o.get(Order_.totalPrice), cb.all(sq)));
