Q12. A system administrator completed a WebSphere Application Server installation by using the Installation Manager. During installation, all defaults were selected for the installation root directories and the shared resources directory. Over time, the administrator has updated the installation with various interim fixes and fix packs.

How can the administrator decrease the size and remove some of the content from the shared resources directory?
A. Manually delete content from the directory.
B. During an update, create a new shared resources directory.
C. Clear the Delete Saved Files option for the Installation Manager.
D. Set the preserve Downloaded Artifacts preference to false.
Answer: D

Q13. A system administrator discovers an issue that requires a change to a federated server. In this cell, WebSphere administrative security is enabled, but application security is not enabled.
How should the administrator make this change? The administrator should use:
A. A web browser to connect to the node agent https port.
B. A web browser to connect to the deployment manager admin_host port.
C. The job manager to submit a job to update the unmanaged server.
D. An ssh connection to the node and modify the client_types.xmI file.
Answer: B
Q14. There are many applications deployed in a large WebSphere Application Server cluster. A system administrator is required to give Configuration role access to a developer for a single application deployed in that cluster.
How should the administrator meet this requirement and restrict Configuration role access for a single application?
A. Create a J2C authentication alias for that developer.
B. Create an Administrative user role and provide Configuration access to the developer.
C. Create an Administrative group role and provide Configuration access to the developer.
D. Create an administrative authorization group, scope it only for that application and create an Administrative user or group role to give Configuration access to the developer.
Answer: A
Q15. An EJB application posts a request message into a JMS destination and waits for a response message on a different JMS destination. To correlate the response message to the request message, the application uses the JMS correlation ld of the message. The application waits up to five seconds for a response before timing out the request.
A Message Driven Bean (MDB) running on a different cluster is responsible for consuming the request message, process it and post a response message.
The destinations are defined in a Service Integration Bus (SIB) within the cell.
Intermittent timeout exceptions have occurred for the requester application. How can a system administrator correlate and analyze the debug information from both requester and consumer applications?
A. Enable High Performance Extensible Logging (HPEL). Use HPEL logViewer command to see debug information.
B. Enable a diagnostic trace in both requester and consumer servers.
Use the Integrated Solutions Console (ISC) to set the admin=all trace. Analyze the trace.
C. Enable High Performance Extensible Logging (HPEL).
Enable Cross Component Trace (XCT) to include request IDs in log and trace records. Use HPEL logViewer command with appropriate filters to see debug information.
D. Using the Integrated Solutions Console (ISC), browse the request message that has timed out and look for any key application data.
Search for exceptions using the key application data in both requester and consumer in native_stderr.log and native_stdout.log.
Answer: C
Q16. A system administrator needs to deploy a new enterprise application which requires that application security be enabled, but, the existing applications in the cell cannot be executed with application security enabled. The cell has the global security and Java 2 security disabled.
How can the administrator handle this requirement?
A. Enable Java 2 security for the cell.
Create a security domain with application security enabled. Associate the security domain to the new application.
B. Enable Java 2 security for the cell.
Create a security domain with application security enabled.
Associate the security domain to a new cluster to be used to deploy the new application,
C. Enable administrative security for the cell.
Create a security domain with application security enabled.
Associate the security domain at the application level for the new application.
D. Enable administrative security for the cell.
Create a security domain with application security enabled.
Associate the security domain to the new cluster where the new application is deployed.
Answer: C

Q17. A system administrator decides to use the advice from the Performance and Diagnostic Advisor to identify the optimum connection pool settings for data sources. In a cell, the data source db2datasource is defined under node scope and used by two servers from that node. The administrator receives two different sets of advice for db2datasource.
. One set of advice suggests increasing the maximum connection pool size for db2datasource.
. The other suggests reducing the maximum connection pool size for db2datasource.
How should the administrator configure the data sources before reusing the Performance and Diagnostic Advisor?
A. Create a data source of the same name under cell scope.
B. Create a data source of the same name under server scope for each server.
C. Increase the minimum connection pool size for the data source.
D. Decrease the maximum connection pool size for the data source.
Answer: B
Q18. After collecting diagnostic trace from a server running under a cell, a system administrator noticed that the trace files contained sensitive information.
To avoid this issue in the future, what can the administrator do?
A. Configure entries in the ras.rawtracelist.properties.
B. Configure suppress Sensitive Trace in the boots trap.properties file.
C. Clear the "Disable logging and tracing of potentially sensitive data" checkbox.
D. Add the entry com.ibm.websphere.logging.RawTraceList=Off to the end of the trace string.
Answer: C

Q19. A web application has a configured session timeout of eight hours and a default LTPA token timeout of two hours. After every two hours, the users have to log in again from their HTTP browser. The system administrator is required to make configuration changes so users only have to log in once, while keeping the above-mentioned timeouts the same. The authentication mechanism available is Kerberos.
How should the administrator do this?
A. Configure the SIP digest authentication.
B. Configure the SPNEGO Web or SPNEGO TAI.
C. Enable Session Management Security Integration.
D. Ensure Web Inbound security attribute propagation is enabled.
Answer: A
Q20. A performance test team was testing the capacity of concurrent users of a web application deployed on a multi-processor server. While testing 250 concurrent users, the administrator discovers connections to the database are failing.
In response, a system administrator increased the connection pool to the maximum limit which the database allows and increased the prepared statement cache size. The test passed, but the application response time was slower.
How should the system administrator tune the data source properties to improve the application response time?
A. Change connection pools purge policy.
B. Decrease connection pool reaps time.
C. Decrease number of free pool partitions.
D. Decrease the prepared statement cache size.
Answer: A
