Free C9510-401: IBM WebSphere Application Server Network Deployment V8.5.5 and Liberty Profile System Administration Exam Questions and Answers

A system administrator ran the backup Config command to backup the configuration using the -nostop option. The administrator changed the properties for the service integration environment by modifying the sib.properties file. During testing the administrator noticed Service Integration Bus related errors and wanted to restore the service integration environment. The administrator used the restore config command, but the tuning properties for the service integration environment were not restored. How can the administrator prevent this issue?

• AA. Use full repository checkpoints for both the backup and the restore.
• BB. Use the restore config command with -nostop for the restore.
• CC. Use the manage profiles command for both the backup and the restore.
• DD. Use the backup config command without -nostop for the backup Use the restore config command without -nostop for the restore.

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?

• AA. Delete the Server tag for CloneId=”b20000002”Delete all of the tags within the Server tag
• BB. Delete the UriGroup tag for default_host_myAppDelete all of the tags within the UriGroup tag
• CC. Delete the VirtualHostGroup tag for default_hostDelete all of the tags within the VirtualHostGroup tag
• DD. Edit the LoadBalanceWeight for server1 to 20Edit the LoadBalanceWeight for server2 to 2

A newly deployed application has authorization errors when invoking EJB methods from a servlet. An additional review indicates that users are authenticated, but do not have the correct authorization. How can a system administrator fix the issue ensuring only authorized access?

• AA. Using the Integrated Solutions Console (ISC), map all security roles to the special subject Everyone.
• BB. Using the Integrated Solutions Console (ISC), map the security roles that are still not mapped to groups in the correct user registry.
• CC. Edit the application using an assembly tool to add a security constraint for the servlet and reinstall the application.
• DD. Edit the application using an assembly tool to remove the security constraint defined for the servlet and reinstall the application.

An application deployed to a multi-node cluster is reported to have slowness and hung threads. A system administrator is asked to review the logs on each node and identify if the hung threads are a false alarm. How can the administrator determine that the hung threads are a false alarm? Analyze the:

• AA. ffdc logs
• BB. SystemErr.log
• CC. SystemOut.log
• DD. native_stderr.log

A system administrator discovers an issue that requires a change to a federated server. In this cell, WebSphere administrative security is enabled, but application security is not enabled. How should the administrator make this change? The administrator should use:

• AA. a web browser to connect to the node agent https port.
• BB. a web browser to connect to the deployment manager admin_host port.
• CC. the job manager to submit a job to update the unmanaged server.
• DD. an ssh connection to the node and modify the client_types.xml file.

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. The administrator notices that the shared resources directory is very large in size and grows larger each time the Installation Manager is run. How can the administrator decrease the size and remove some of the content from the shared resources directory?

• AA. Manually delete content from the directory.
• BB. During an update, create a new shared resources directory.
• CC. Clear the Delete Saved Files option for the Installation Manager.
• DD. Set the preserveDownloadedArtifacts preference to false.

A system administrator wants to learn some of the Python scripting commands for the administration of the environment. Which product feature should the administrator use?

• AA. The wsadmin.properties file to load a profile.
• BB. The AdminTask object to generate wsadmin scripts.
• CC. The guided activities panel from the Integrated Solutions Console (ISC).
• DD. The "Log command assistance commands" option in the Integrated Solutions Console (ISC).

A system administrator has created a Jython script called globalScript.py. What should the administrator do to ensure globalScript.py is loaded when the wsadmin shell is used?

• AA. Compile globalScript.py to a Java class in the bin directory.
• BB. Invoke wsadmin with the argument –profileName globalScript.py.
• CC. Modify the configureCustomProperty script to import globalScript.py.
• DD. Set the script profiles in the wsadmin.properties file to load globalScript.py.

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?

• AA. Configure the storm drain health policy.
• BB. Configure the on demand router (ODR) transport chain to tune inbound connections.
• CC. Monitor the JVM heap usage to determine a new server weight.
• DD. Enable the PMI Extended statistic set and use the Connection Pool summary report.
