  You can use application properties files to install enterprise application files on a server or cluster, update deployed applications or modules, or uninstall deployed applications or modules. Drag or copy a properties file to a monitored directory

  and the product performs the deployment action described in the properties file. The enterprise application files that you can install, update, or uninstall using properties files include enterprise archive (EAR), web archive (WAR), Java archive

  (JAR), and Session Initiation Protocol (SIP) archive (SAR) files.

• Question 62:

  A developer created an enterprise application which contained data source and security role information. The developer asked a system administrator to install this application to an application server where global security is enabled using the Integrated Solutions Console (ISC). A new data source was configured at the server scope for the use of this application. While load testing the application, the developer noticed that the attributes configured on the new data source were ignored by the application server.

  How can the administrator ensure that the attributes configured on the new data source are used by the application server?

  A. Create the data source under cell scope instead of server scope.
  B. Delete any data source of the same name defined under node, cluster or cell scope.
  C. Reinstall the application and clear the Process embedded configuration check box.
  D. Correct the component-managed and container-managed authentication aliases set on the data source.
  C. Reinstall the application and clear the Process embedded configuration check box.

  Process embedded configuration

  Specifies whether the embedded configuration should be processed. An embedded configuration consists of files such as resource.xml, variables.xml, and deployment.xml. You can collect WebSphere Application Server-specific deployment

  information and store it in the application EAR file. Such an EAR file can then be installed into a WebSphere Application Server configuration, using application management interfaces that are described in the topic, Installing an application

  through programming. One such application EAR file is an enhanced EAR file, which is created when you export an already installed application. The embedded configuration check box identifies such an enhanced EAR file. By default, the

  check box for "process embedded configuration" is checked if the application is detected to be an enhanced EAR. The application install options are prepopulated with the information from the embedded configuration whether the check box

  for "process embedded configuration" is checked or not. Users can overwrite these values during the deployment process.

• Question 64:

  A system administrator needs to configure a JDBC provider and a data source for an application in a clustered environment. The administrator also needs to copy the JDBC drivers from the database server to the application server machines.

  How can the administrator meet these requirements?

  A. Create a JDBC provider and the data source in the cluster scope.Copy the driver to all nodes.Set the environment variable at the node level to the driver's path.
  B. Create a JDBC provider in the server scope and the data source in the node scope.Copy the driver to all application servers.Set the environment variable at the node level to the driver's path.
  C. Create a JDBC provider in the node scope and the data source in the cell scope.Copy the driver to the deployment manager.Set the environment variable at the server level to point to the deployment manager path.
  D. Create a JDBC provider in the application scope and the data source in the server scope.Copy the driver to all application server directories.Set the environment variable in each JVM to the driver's path.
  A. Create a JDBC provider and the data source in the cluster scope.Copy the driver to all nodes.Set the environment variable at the node level to the driver's path.

• Question 65:

  A web application is hosted on an application server that receives HTTP requests from a third party application named myApp. The URIGroup mapping for this application is called default_host_myApp.

  The development team asks a system administrator to configure the HTTP plug-in to prevent routing requests to any application server except server1.

  The following exhibit shows the parts of the plugin-cfg.xml file that are relevant for myApp. The UriGroups for other applications are not shown in the exhibit.

  

  What should the administrator do to the plugin-cfg.xml file to ensure that requests for default_host_myApp URIGroup are routed only to machine1?

  A. Delete the Server tag for CloneId="b20000002"Delete all of the tags within the Server tag
  B. Delete the UriGroup tag for default_host_myAppDelete all of the tags within the UriGroup tag
  C. Delete the VirtualHostGroup tag for default_hostDelete all of the tags within the VirtualHostGroup tag
  D. Edit the LoadBalanceWeight for server1 to 20Edit the LoadBalanceWeight for server2 to
  A. Delete the Server tag for CloneId="b20000002"Delete all of the tags within the Server tag

• Question 66:

  A system administrator completed a WebSphere Application Server installation by using the Installation Manager. During installation, all defaults were selected for the installation root directories and the shared resources directory. Over time, the administrator has updated the installation with various interim fixes and fix packs.

  D. A heterogeneous cell with enough server to support the peak load spread across multiple nodes on the same machine.
  C. A dynamic cluster with autonomic managers, application placement controller and intelligent routers.

  ---

  A dynamic cluster is a server cluster that uses weights and workload management to balance the workloads of its cluster members dynamically, based on performance information that is collected from the cluster members. Dynamic clusters

  enable application server virtualization.

  A dynamic cluster is an application deployment target that can expand and contract depending on the workload in your environment. Dynamic clusters work with autonomic managers, including the application placement controller and the

  dynamic workload manager to maximize the use of your computing resources. Dynamic clusters are required for many of the Intelligent Management autonomic functions, including high availability and service policies.
