Q11. An organization updated their LDAP directories and modified user roles. The roles that were configured to have access to a highly secured enterprise application were deleted and new roles with new names were created. The application then had security related exceptions.
How can a system administrator resolve the exceptions and restore security for the application?
A. Modify the mapping of security roles of the application to the new LDAP roles.
B. Modify the application and remove all security constraints and redeploy the application.
C. Modify the application to have a run as role for each new LDAP role and redeploy the application.
D. Create an administrative authorization group with administrator privileges scoped for the application with an administrative group role for the new LDAP roles.
Answer: D
Explanation: Reference: http://www.novell.com/documentation/idmrbpm36/install/data/bb1zmw0.html (See the Role of Administrator).
Q12. A WebSphere system administrator needs to install the Installation Manager (IM) on an unmanaged node on a host named <machine2>. The deployment manger is running on a host named <machine1>.
What step must the administrator take before submitting a job from the Integrated Solutions Console (ISC) to install the IM on <machine2>?
A. Install a node agent on <machine2>.
B. Install the job manager on <machine1>.
C. Start the job manager on <machine1>.
D. Register <machine2> as a target for job manager.
Answer: A
Q13. A system administrator was asked by the development team to inform them of any warning message which contains a string "Connection" on a WebSphere Application Server with High Performance Extensible Logging (HPEL) enabled.
What should the administrator do to continuously monitor logs for the required message?
A. Configure log detail levels to include filter on "Connection" string.
B. Use the Log Viewer in the administrative console with filter on "Connection" string.
C. Use the logviewer.sh or logviewer.bat command with appropriate options.
D. Use the Log Viewer in the administrative console with filter on "Connection" string and enable the 'Refresh automatically' feature.
Answer: C

Q14. 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
Q15. While monitoring a cluster in the cell, the administrator notices that one server in the cluster periodically loses connections to the database. When this happens, requests to the server have a significantly decreased response time and various error conditions are listed in the log files for the server. Since the error codes are returned quickly, the server starts returning responses faster than the average service times for the application. Due to this,
the weight for the server is increased and a large percentage of incoming requests are being routed to the erroneous server and the server is getting overloaded with requests.
How can the administrator detect these conditions in the future and take action to prevent this problem?
A. Configure the storm drain health policy.
B. Configure the on demand router (ODR) transport chain to tune inbound connections.
C. Monitor the JVM heap usage to determine a new server weight.
D. Enable the PMI Extended statistic set and use the Connection Pool summary report.
Answer: D
Q16. 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
Q17. A system administrator has added a server cluster as a member of a service integration bus (SIB). The administrator needs to configure one messaging engine for each server in this cluster and to have a failover location for each messaging engine.
What should the administrator do to achieve the required design?
A. Configure a new messaging engine in each server to support failover.
B. Configure the data store for each messaging engine for each server in the cluster.
C. Select scalability with high availability as the messaging engine policy.
D. Create a core group policy to restrict each messaging engine to a particular server.
Answer: C
Explanation: The scalability with high availability configuration ensures that there is a messaging engine for each server in a cluster, and that each messaging engine has a failover location.

Q18. A system administrator needs to create a cell for a test environment. The administrator uses the Profile Management Tool (PMT) to create the deployment manager profile using the advanced profile creation option and creates a custom profile using the typical profile creation option. The administrator examines the log files for the custom profile creation and sees an INSTCONFFAIL message indicating the deployment manager was not running during the custom profile creation.
How should the administrator fix this?
A. Delete the custom profile. Start the deployment manager. Create the custom profile again.
B. Start the deployment manager. Use PMT to re-create the custom profile.
C. Use the syncNode command to synchronize the node.
D. Run the addNode command to federate the custom profile.
Answer: A
Q19. A system administrator has installed WebSphere Application Server Network Deployment V8.5.5 using the silent installation process and needs to verify that the installation completed successfully.
What does the administrator need to do to verify a successful installation?
A. Launch the Installation Manager GUI, and verify the installation by going to File -> View Installed Packages.
B. Run the command IBMIM list installed Packages and check that the appropriate WebSphere Application Server package is listed.
C. Check for INSTCONFSUCCESS message at the end of the <webSphere Application Server install directory><log directory>log.txt file.
D. Use the installer command to compare the checksum of the product file to the correct checksum value in the bill-of-materials file and make sure that the checksums match.
Answer: C

B. ibmconfig folder in the application after using the EARExpander command.
C. Web deployment descriptor using IBM Assembly and Deploy Tools.
D. Security role to user/group mapping by using the Integrated Solutions Console (ISC).
