NO.1 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 reap time.
C. Decrease number of free pool partitions.
D. Decrease the prepared statement cache size.
Answer: A

NO.2 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

NO.3 A system administrator suspects that the slow performance of an application might be caused
by lock contention.
To debug this further, what can the administrator do using IBM Support Assistant?
A. Analyze the running server using IBM Monitoring and Diagnostic Tools for Java -Health center.
B. Collect a javacore and analyze it using IBM Monitoring and Diagnostic Tools for Java Health Center.
C. Collect three thread dumps at equal time intervals and analyze them using IBM Monitoring and
Diagnostic Tools for Java - Dump Analyzer.
D. Collect three system dumps at equal time intervals and analyze them using IBMMonitoring and
Diagnostic Toolsfor Java - Memory Analyzer.

NO.4 Which one of the following options describes the runtime flow starting from the client browser
in a clustered WebSphere Application Server Network Deployment topology?
A. HTTP server -> job manager -> admin agent -> HTTP server plug-in
B. Load balancer -> HTTP server -> HTTP server plug-in -> application server
C. Application server -> node agent -> deployment manager -> load balancer
D. Deployment manager -> node agent -> HTTP server plug-in -> HTTP server
Answer: A

NO.5 How can a system administrator secure a WebSphere Application Server environment to ensure
that an application code will not be allowed to access any files in the server's file system?
A. Configure the CSIv2 outbound communications under RMI/IIOP security.
B. Configure the file-based repository and create the fileRegistry.xml file.
C. Enable Java 2 security and configure the app.policy and was .policy files.
D. Use the AdminTask deleteAuthorizationGroup to remove application access.

NO.6 The application placement controller has been configured with elasticity mode enabled.
Intermittently, all instances of a dynamic cluster are removed. After further review, the system
administrator noticed that it occurs during peak load on another dynamic cluster.
The administrator wants to keep at least one instance available. Which configuration is needed in the
dynamic clusters?
A. Enable application lazy start with elasticity mode.
B. Set theproactiveldleStopcustom property to true
C. Set the Number of instances to a value greater than zero.
D. Disable the option"If other dynamic clusters need resources, stop all instances of this cluster
during periods of inactivity".

NO.7 There are many applications deployed in a large WebSphere Application Server cluster. A
system administrator is required to giveConfigurationrole access to a developer for a single
application deployed in that cluster.
How should the administrator meet this requirement and restrictConfigurationrole access for a single
application?
A. Create a J2C authentication alias for that developer.
B. Create an Administrative user role and provideConfigurationaccess to the developer.
C. Create an Administrative group role and provideConfigurationaccess to the developer.
D. Create an administrative authorization group, scope it only for that application and create an
Administrative user or group role to giveConfigurationaccess to the developer.
Answer: A
