Question 3

A system administrator is required to monitor the application server logs for heap memory issues and determine if the heap memory usage is reaching close to 70% of the maximum heap. The application server is configured with an initial heap of 256 MB and a max heap of 1 GB.
How should the administrator determine if the application server is utilizing 70% of the max allocated heap memory?

A. Configure Initial heap to be equal to the max heap.Trigger a heap dump from the
Integrated Solutions Console (ISC).Analyze the heap dump.

B. Configure WebSphere Application Server to increase max heap.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.

C. Configure WebSphere Application Server to enable verbose garbage collection.Analyze the garbage collection cycles in the native logs.

D. Check the System logs for OutOfMemoryErrors.Trigger a heap dump from the
Integrated Solutions Console (ISC).Analyze the heap dump.

Question 4

A system administrator is configuring the security of a new environment. The administrator has been asked to configure one LDAP server that has different sub-trees for business users and administration users.
What should the administrator do to implement the required security configuration?

A. Install and configure a TAI (Trust Association Interceptor)

B. Configure a security domain for the stand-alone LDAP server.

C. Use Federated repositories and configure the supported entity types.

D. Use Stand-alone custom registry and configure the flat file implementation.

Question 5

A new cell contains a cluster with members defined in two managed nodes running on two different machines. The cell also contains two unmanaged nodes running on HTTP servers with HTTP plug-in. Session persistence has been enabled.
Which additional component(s) can the system administrator configure to make this environment highly available?

A. Configure primary and backup load balancers for the HTTP servers.

B. Configure High Performance Extensible Logging.

C. Configure a DMZ secure proxy.

D. Enable administrative security.

Correct Answer: A

Question 6

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. Monitor the JVM heap usage to determine a new server weight.

B. Configure the storm drain health policy.

C. Enable the PMI Extended statistic set and use the Connection Pool summary report.

D. Configure the on demand router (ODR) transport chain to tune inbound connections.

Question 7

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. Start the deployment manager.Use PMT to re-create the custom profile.

B. Use the syncNode command to synchronize the node.

C. Delete the custom profile.Start the deployment manager.Create the custom profile again.

D. Run the addNode command to federate the custom profile.

Question 8

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 suppressSensitiveTrace in the bootstrap.properties file.

B. Add the entry com.ibm.websphere.logging.RawTraceList=off to the end of the trace string.

C. Clear the "Disable logging and tracing of potentially sensitive data" checkbox.

D. Configure entries in the ras.rawtracelist.properties.
