A system administrator in a bank was asked by business users to determine the most accessed JSP page in a web application at normal work load for marketing purpose.

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.
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.

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.
A system administrator runs a Python script that creates and configures several servers and realizes that the script fails before completing. Although many tasks succeeded, they are rolled back when the script fails.

A. AdminApp.update ()
B. AdminConfig.save()
C. AdminControl.invoke(server, 'sync')
D. AdminTask.backupJobManager('server')
A system administrator is required to create a star topology for multi-cell performance management for three WebSphere Application Server cells.

C. true in all three WebSphere Application Server cells.
D. true in one WebSphere Application Server cellfalse in the other two WebSphere Application Server cells.
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.

B. Modify the application and remove all security constraints and redeploy the application.
C. Modify the application to have a runAs role for each new LDAP role and redeploy the application.

After installing an enhanced EAR in a WebSphere Application Server environment, a system administrator with Configurator privileges is able to see a JDBC provider and a data source in the Integrated Solution Console (ISC) but is not able to delete these resources.

A. Configure a cluster of external HTTP servers.
B. Enable the prefer local option on the cluster members.
C. Set up a Caching Proxy server between the external web server and the application server.
D. Place an On Demand Router (ODR) between the external web server and the application servers.
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. Check the System logs for OutOfMemoryErrors.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.
B. Configure WebSphere Application Server to enable verbose garbage collection.Analyze the garbage collection cycles in the native logs.
C. Configure Initial heap to be equal to the max heap.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.
D. Configure WebSphere Application Server to increase max heap.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.
A customer has enabled LTPA as their authentication mechanism and has web resources that are not secured by proper security constraints. A system administrator is required to ensure that all web resources are secured.
