Question #1
Assuming there are no custom properties defined in current plugin-cfg.xml file, what should be done before running the GenPluginCfg command?
- A . Delete the global plugin-cfg.xml in the <profile_root>/config/cells directory.
- B . Delete the current plugin-cfg.xml in the <profile_root>/config/cells directory.
- C . Clear the Enable automated web server configuration processing option in the web server plugin configuration service.
- D . Use either the Integrated Solutions Console or the ConfigurewebServerDefinition.jacl script to create a web server definition.
Correct Answer: B
B
Explanation:
Delete the plugin-cfg.xml file in the profile_root/config/cells directory before you use the GenPluginCfg command. Otherwise, configuration changes do not persist to the plugin-cfg.xml file.
However, do not delete the plugin-cfg.xml file if you have custom properties that you previously set in it that you need to persist.
Note: You can update the global plugin-cfg.xml file using the administrative console or running the GenPluginCfg command for all of the clusters in a cell.
However, you must delete the config/cells/plugin-cfg.xml file before you update the global plugin-cfg.xml file. If you do not delete the config/cells/plugin-cfg.xml file, only the new properties and their values are added to the global plugin-cfg.xml file. Any updates to existing plug-in property values are not added to the global plugin-cfg.xml file.

Question #4
An administrator notices that the Message Driven Beans (MDBs) are slow to complete, and decides to increase the ‘Maximum concurrent MDB invocations per endpoint’.
Which thread pool should be tuned to ensure it can run the maximum number of MDBs without waiting?
- A . Default
- B . WebContainer
- C . SIBJMSRAThreadPool
- D . WMQJCAResourceAdapter
Correct Answer: C
C
Explanation:
The thread pool WMQJCAResourceAdapter is referenced by the WebSphere MQ (WMQ) resource adapter inbound delivery to MDB’s. When WebSphere MQ resource adapter is used in conjunction with the activation specs, the resource adapter’s Work Manager uses the values defined for the WMQJCAResourceAdapter for utilizing the total number of threads defined.
Ideally the default values provides for the WMQJCAResourceAdapter will be sufficient for the resource adapter. But in case there is an heavy load on the system processing huge number of messages, you can increase the maximum number of threads the thread pool can hold.

Through what protocol can a Java client directly access EJBs running on an application server?
- A . JDBC
- B . RMI/IIOP
- C . SOAP/JMS
- D . SOAP/HTTP
Correct Answer: B
B
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.

Question #17
What data source property can an administrator configure to minimize the chances of encountering StaleConnectionExceptions?
- A . Minimum connections = 0
- B . Reap Timeout < Unused Timeout
- C . Purge Policy = FailingConnectionOnly
- D . Unused Timeout > Half firewall timeout
Correct Answer: C
C
Explanation:
The configuration options below help minimize the chances of encountering StaleConnectionExceptions by helping to ensure that your WebSphere Application Server maintains control of database connections, specifically, the only one closing them, rather than other components in your network:
The datasource MIN connections should be set to 0. By setting a MIN > 0, you are telling the application server that this number of connections will be valid for the life of the application server JVM. Unless you can guarantee the MIN number of connections will never be timed out or dropped, setting a MIN will cause a StaleConnectionException when the connection becomes invalid.

- C . The configuration scope determines which ODRs are included in plugin-cfg.xml.
- D . The configuration scope determines which ODRs are included in HTTPplugin-cfg.xml.
Correct Answer: C
C
Explanation:
In a topology with a web server which forwards requests to an on demand router (ODR), the ODR can be set to dynamically generate and update the web server plug-in configuration file plugin-cfg.xml. By configuring an ODR to dynamically update plugin-cfg.xml, you avoid manually updating the file during administrative actions, which can affect the content.
