CORBA is a standard for A             Messaging using virtual channels called QueuesB              Standardized development practicesC              Messaging using virtual channels called topicsD              Accessing distributed object

 Choice D is correct. Common Object Request Broker Architecture (CORBA) is a standard for distributed communication involving applications written using different languages. Hence choice D is 

 RMI-IIOP does not provide which of the following capabilities?  A             Remote Method InvocationB              Stub DownloadsC              Objects pass by value (state only)D              Distributed Garbage Collection

 Choices B and D are correct. RMI-IIOP does not support Stub downloads and distributed garbage collection. Hence choices B and D are correct.Both Remote Method Invocation and Objects pass by 

 Which of the following are not true about Screen Scrapers? A             Screen scrapers function as Terminal Emulators on one end and as Object Interfaces on the other.B              Screen Scraping may be a useful tool when used in conjunction with the off-board servers.C              Changes to

 Choices C and D are correct. When using screen scrapers, any changes to the legacy user interface will also affect the new GUI. Also screen scraping is the best alternative only if the existing 

 Which of the following methods may be present in the Home Interface of an Entity Bean? A             create()B              findByPrimaryKey()C              remove()D              locateByPrimaryKey()E             

 Choices A, B and C are correct. The Home Interface provides methods for creation, location and removal of beans. Hence you could find create(), findByPrimaryKey() and remove() methods in the 

 Undefined Primary Keys refers to? A             Refers to Entity Beans that do not use Primary KeysB              Primary Keys that are defined during developmentC              Primary Keys that remain undefined until the bean is deployedD             

 Choice C is correct. One problem with container-managed persistence in EJB 1.0 was that the bean developer had to define the primary key during development. This forced the developer to make 

 Which of the following are valid life cycle states for a Stateless Session Bean? A             Does not ExistB              Pooled StateC              Method Ready PoolD              Passive

 Choices A and C are correct. The two valid states in a Stateless Session Bean's life cycle are 'Does Not Exist' and 'Method Ready Pool.' When Beans are not instantiated 

 Both CMT and BMT may be used with Entity and Session Beans. True or False? A             TrueB              False

 Choice B is correct With EJB1.1 only Session Beans with equal to 'Bean' can have bean-managed transactions. Entity Beans are not allowed to be BMT beans. Hence choice 

 A session bean called SomeBean has a method called someMethod(), which calls someOtherMethod (same bean) followed by someOtherBeanMethod() of SomeOtherBean. SomeOtherBean is an Entity Bean with CMT. Which of the following is true?  A             SomeOtherBean has no control on the transaction since it is a CMT bean.B              SomeOtherBean has full access

 Choice C is correct. Only BMT beans have access to the User-Transaction from the EJBContext. The EJBContext provides the methods setRollbackOnly() and getRollbackOnly(), to provide CMT beans 

 Which of the following is not a resource management technique?  A             Maintaining a smaller pool of Stateless Beans to serve a large number of clients.B              Providing Database Connection PoolingC              Persistence of Entity BeansD             

 Choice C is correct. Persistence of Entity beans is the ability to save data represented by the bean into a database. It is not a resource management technique. Choice C is false and therefore 

 Which of the following are invalid states in the life of a Stateful Session Bean? A             Does Not ExistB              Method Ready PoolC              Method Ready in TransactionD              Method ReadyE             

 Choices B, E and F are correct. The valid life cycle states of a Stateful Session Bean are 'Does Not Exist', 'Method Ready', 'Method Ready in Transaction' and 'Passive'.
