Through what protocol can a Java client directly access EJBs running on an application server?
JDBC
RMI/IIOP
SOAP/JMS
SOAP/HTTP
Correct answer: D
Explanation:
Provided that it uses the correct protocols (SOAP, HTTP, WSDL), any web service client can access a stateless session bean, whether or not the client is written in the Java programming language. The client doesn’t even “know” what technology implements the service: stateless session bean, JAX-WS, or some other technology. In addition, enterprise beans and web components can be clients of web services. This flexibility enables you to integrate Java EE applications with web services.

What is a benefit of using the IBM Extended Cache Monitor?
It invalidates cacheids.
It displays the contents of the cache instances.
It displays the contents of object cache instances.
It displays the dependency ids of the cache instances.
Correct answer: C
Explanation:
The IBM Extended Cache Monitor for IBM WebSphere Application Server provides you with two functions that are not available with the cache monitor that is supplied with WebSphere Application Server. These two functions enable you to:display the contents of object cache instances display the Dynamic Cache mbean statistics for cache instances Reference: https://www.ibm.com/developerworks/websphere/downloads/cache_monitor.html

Which two methods are used for communicating session linkages between the client and the server? (Choose two.)
Cookies
LTPA Token
Rest Services
URL Rewriting
HTTP Response codes
Correct answer: CE
Explanation:
Representational State Transfer (REST) is a lightweight framework for designing applications that use HTTP to make calls. REST uses HTTP to perform the Create, Read, Update, and Delete (CRUD) operations between client and server. Applications interact with the services by using HTTP, POST, PUT, GET, and DELETE operations.
