IBM C9510-401 Online Questions & Answers

• Question 1:

  A system administrator has created a Jython script that will run in WebSphere Network cell where administrative security is enabled. This script is named doUpdate.py and will be run by using the following:

  wsadmin –connType RMI –f doUpdate.py

  How can the administrator suppress a user/password prompt from appearing when this script is run?

  Set the user and password in the:

  A. sas.client.props file.
  B. ssl.client.props file.
  C. soap.client.props file.
  D. wsadmin.properties file.
  A. sas.client.props file.

  ---

  explanation:

  The user Id and password needed for wsadmin to connect to a secured server can be supplied as command line options and in properties files. If used together, command line options take precedence over what is in the properties files. The

  properties files are located at Profile_root/properties.

  If you use a Remote Method Invocation (RMI) connector or a JSR160RMI connector, set the following properties in the sas.client.props file with the appropriate values:

  com.ibm.CORBA.loginUserid=

  com.ibm.CORBA.loginPassword=

• Question 2:

  A system administrator needs to set a new Liberty profile environment to support an application.

  What should the administrator do to enable this environment for high availability and scalability of the application?

  A. Define multiple server members in one collective controller.
  B. Define multiple servers in a cluster in one collective controller.
  C. Define multiple collective controllers within a Liberty collective.
  D. Define multiple server members in multiple collective controllers.
  B. Define multiple servers in a cluster in one collective controller.

  ---

  explanation:

  Setting up Liberty server clusters

  A Liberty can be configured into a server cluster for application high availability and scale. The collectiveController-1.0 feature and its capabilities are available only in multiple-server products such as WebSphere?Application Server Liberty

  Network Deployment and WebSphere Application Server Liberty for z/OS. The feature is not available in single- server products such as WebSphere Application Server Liberty, WebSphere Application Server Liberty - Express, or WebSphere

  Application Server Liberty Core. If you have a multiple-server product installation, you can use its collectiveController-1.0 feature to work with collective members from single-server products.

• Question 3:

  A web application was deployed on a WebSphere Application Server cluster. While users are using the application, one of the cluster servers fails and the users lose their working data. What can the system administrator configure to ensure users can continue to work if one of the cluster server fails?

  A. An increased session timeout.
  B. A cluster of external HTTP servers.
  C. A load balancer to spread work between existing servers.
  D. A WebSphere eXtreme Scale HTTP session management.
  D. A WebSphere eXtreme Scale HTTP session management.

  ---

  explanation:

  WebSphere eXtreme Scale can dynamically process, partition, replicate, and manage application data and business logic across hundreds of servers. It provides transactional integrity and transparent fail-over to ensure high availability, high reliability, and consistent response times.

• Question 4:

  There are many applications deployed in a large WebSphere Application Server cluster. A system administrator is required to give Configurator role access to a developer for a single application deployed in that cluster. How should the administrator meet this requirement and restrict Configurator role access for a single application?

  A. Create a J2C authentication alias for that developer.
  B. Create an Administrative user role and provide Configurator access to the developer.
  C. Create an Administrative group role and provide Configurator access to the developer.
  D. Create an administrative authorization group, scope it only for that application and create an Administrative user or group role to give Configurator access to the developer.
  D. Create an administrative authorization group, scope it only for that application and create an Administrative user or group role to give Configurator access to the developer.

  ---

  explanation:

  Fine-grained administrative security

  In releases prior to WebSphere?Application Server version 6.1, users granted administrative roles could administer all of the resources under the cell. WebSphere Application Server is now more fine-grained, meaning that access can be

  granted to each user per resource.

  For example, users can be granted configurator access to a specific instance of a resource only (an application, an application server or a node).

  To achieve this instance-based security or fine-grained security, resources that require the same privileges are placed in a group called the administrative authorization group or authorization group. Users can be granted access to the

  authorization group by assigning to them the required administrative role.

• Question 5:

  An application contains a web services client and the application is deployed and running. A system administrator has to add a response timeout to the deployed web services client, so the call fails in a timely fashion. Which artifact should the administrator use?

  A. web.xml
  B. was-webservices-sca.xml
  C. ibm-webservices-bnd.xml
  D. ibm-webservicesclient-bnd.xml
  D. ibm-webservicesclient-bnd.xml

  ---

  explanation:

  The ibm-webservicesclient-bnd.xmi deployment descriptor file contains information for the web services run time that is WebSphere?product-specific. This deployment descriptor file is used with Java API for XML-based web services.

• Question 6:

  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?

  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.
  A. Delete the custom profile.Start the deployment manager.Create the custom profile again.

  ---

  explanation:

  Deleting profiles. You can delete a profile using the manageprofiles command. If the command fails, you can delete the profile using operating system commands.

  Before you begin: If a node within a profile is federated to a deployment manager, before you delete the profile, stop the node and remove the node from the deployment manager. Otherwise, an orphan node remains in the deployment manager.

• Question 7:

  A system administrator has created a Python script that will run in WebSphere Network cell where administrative security is enabled. This script is named doUpdate.py and will be run by using the following:

  wsadmin -connType RMI -f doUpdate.py

  How can the administrator suppress a user/password prompt from appearing when this script is run?

  Set the user and password in the:

  A. sas.client.props file.
  B. ssl.client.props file.
  C. soap.client.props file.
  D. wsadmin.properties file.
  A. sas.client.props file.

• Question 8:

  A JAX-WS EJB stateless session bean web service needs to be accessed by consumers outside the corporate domain. Which configuration will help a system administrator meet the requirement?

  A. Open firewall ports for both bootstrap and orb listener ports within the cell.
  B. Configure plug-in in the DMZ to send request to the cluster members.
  C. Configure on demand router (ODR) in the DMZ to send requests to the cluster members.
  D. Configure HTTP tunneling to send the client-side Object Request Broker (ORB) request to the server-side ORB.
  A. Open firewall ports for both bootstrap and orb listener ports within the cell.

• Question 9:

  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 10:

  A system administrator runs a Jython script that creates and configures several servers and realize that the script fails before completing. Although many tasks succeeded, they are rolled back when the script fails. Before running the script again, what can the administrator add to the script after each task so the completed tasks are committed even if other tasks fail?

  A. AdminApp.update()
  B. AdminConfig.save()
  C. AdminControl.invoke(server, `sync')
  D. AdminTask.backupJobManager(`server')
  B. AdminConfig.save()

  ---

  explanation:

  AdminConfig.save()to save changes after script execution.
