Questions # 12:

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?

Options:

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.

Questions # 17:

A system administrator has created a wsadmin script with several steps to install and configure an application and some resources in a WebSphere Application Server process. The script executed but the application was not installed successfully. The administrator suspects that the script has problems.

How can the administrator test and debug the script?

Options:

A.

In WebSphere Application Server Developer Tools for Eclipse, right click on the script file and select Validate from context menu.


B.

Execute the script using the wsadmin with the option –conntype NONE and monitor the commandAssistanceJythonCommands.log file.


C.

Use WebSphere Application Server Developer Tools for Eclipse in the debug perspective connected to the server and execute the script step by step.


D.

Run the script using wsadmin with these parameters: -lang jython –javaoption “-Xdebug” and then execute the logViewer command with the option -listInstances

Questions # 18:

The administrator needs to identify any security role references and security constraints in a web application.

How can the administrator identify these roles and constraints?

Options:

A.

ibm-application-ext.xml file using a text editor.


B.

ibmconfig folder in the application after using the EARExpander command.


C.

Web deployment descriptor using IBM Assembly and Deploy Tools.


D.

Questions # 19:

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?

Options:

A.

Enable application lazy start with elasticity mode.


B.

Set the proactiveIdleStop custom 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”.


Expert Solution
Questions # 20:

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?

Options:

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.
