QUESTION 11

Which type of fix would typically be downloaded to address a specific problem?

Correct Answer: A
A WebSphere Commerce interim fix (iFix) is a software patch that contains fixes for one or more APARs. A WebSphere Commerce cumulative iFix is a comprehensive collection of interim fixes for a specific release. Both types of fixes are installed with theWebSphere Commerce Update Installer (UPDI).
Note: An Authorized Program Analysis Report, or APAR, is a formal report from IBM development to customers that have notified IBM of a problem or suspected defect. If IBM development is able to confirm the existence of the issue they will create an APAR with any known work around and perhaps an indication of which future release, if any, of the IBM program they intend to target for a formal fix to the defect and whether or not a Program Temporary Fix (PTF) is planned. The APAR will then be published so that it is visible to supported customers.

QUESTION 12

Assuming there are no custom properties defined in current plugin-cfg.xml file, what should be done before running the GenPluginCfg command?

Correct Answer: B
Delete the plugin-cfg.xml file in the profile_root/config/cells directory before you use
theGenPluginCfgcommand. Otherwise, configuration changes do not persist to the plugin- cfg.xml file. However, do not delete the plugin-cfg.xml file if you have custom properties that you previously set in it that you need to persist.
Note:You can update the global plugin-cfg.xml file using the administrative console or running the GenPluginCfg command for all of the clusters in a cell. However, you must delete the config/cells/plugin-cfg.xml file before you update the global plugin-cfg.xml file. If you do not delete the config/cells/plugin-cfg.xml file, only the new properties and their values are added to the global plugin-cfg.xml file. Any updates to existing plug-in property values are not added to the global plugin-cfg.xml file.

QUESTION 13

An administrator noticed that one of the servers in the core group is experiencing OutOfMemory. As a result, other servers in the core group failed to start.
What core group custom property should the administrator tune to prevent the affected server from impacting other servers in the core group?

Correct Answer: A
IBM_CS_OOM_ACTION
Use this custom property to explicitly enable exception handlers that are specific for OutOfMemoryExceptions that occur when sending or receiving network messages. When this property is set to Isolate, if an OutOfMemoryException occurs when a network message is being sent or received, these exception handlers stop High Availability Manager communications to the Out of Memory process.
If IBM_CS_OOM_ACTION=Isolate is not added to the configuration settings for a core group, if a core group process runs out of memory, the Out of memory process might not
be able to respond to all messages. This situation prevents multi-step protocols from completing, and prevents the starting server from receiving its initial view of the distributed state.

QUESTION 14

To write a Jython script to stop a running application server, an administrator should use which administrative object?

Correct Answer: D
You can use the wsadmin tool to stop applications.
There are two ways to complete this task.Firstly you canuse the AdminControl object to stop the application. Alternatively, you can use the scripts in the AdminApplication script library to start, stop, and administer your application configurations.

QUESTION 15

What determines which On Demand Routers (ODRs) a Web server forwards requests to?

Correct Answer: C
In a topology with a web server which forwards requests to an on demand router (ODR), the ODR can be set to dynamically generate and update the web server plug-in configuration file plugin-cfg.xml. By configuring an ODR to dynamically update plugin- cfg.xml, you avoid manually updating the file during administrative actions, which can affect the content.
