IBM C2180-401 Online Questions & Answers

• Question 21:

  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.

• Question 22:

  A system administrator needs to view the list of certificates for unmanaged web server located on a remote system. How should the administrator do this?

  A. View the plugin-cfg.xml
  B. Look at the SSL configuration in the httpd.conf
  C. Use iKeyman to view the keyring.
  D. Use the administrative console to check the content of the cell default keystore.
  B. Look at the SSL configuration in the httpd.conf

• Question 23:

  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?

  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.
  D. Enable the PMI Extended statistic set and use the Connection Pool summary report.

• Question 24:

  A system administrator needs to deploy a new enterprise application which requires that application security be enabled, but, the existing applications in the cell cannot be executed with application security enabled. The cell has the global security and Java 2 security disabled.

  How can the administrator handle this requirement?

  A. Enable Java 2 security for the cell. Create a security domain with application security enabled. Associate the security domain to the new application.
  B. Enable Java 2 security for the cell. Create a security domain with application security enabled. Associate the security domain to a new cluster to be used to deploy the new application,
  C. Enable administrative security for the cell. Create a security domain with application security enabled. Associate the security domain at the application level for the new application.
  D. Enable administrative security for the cell. Create a security domain with application security enabled. Associate the security domain to the new cluster where the new application is deployed.
  C. Enable administrative security for the cell. Create a security domain with application security enabled. Associate the security domain at the application level for the new application.

• Question 25:

  The computer where a federated node was running had a failure and cannot be recovered. A system administrator wants to recreate the node with the same configurations in another computer. Which steps should the administrator execute in order to recover the damaged node?

  A. Configure the new computer with a different hostname. Create a custom profile with the same name. Federate to the cell using the command addNode with the default options.
  B. Configure the new computer with a different hostname. Create a custom profile with a different name. Federate to the cell using the command addNode with the option -asExistingNode.
  C. Configure the new computer with the same hostname. Create a custom profile with the same name. Federate to the cell using the command addNode with the option -asExistingNode.
  D. Configure the new computer with the same hostname. Create a custom profile with the same name. Federate to the cell using the command addNode with the options -includeapps.
  B. Configure the new computer with a different hostname. Create a custom profile with a different name. Federate to the cell using the command addNode with the option -asExistingNode.

• Question 26:

  A new cell contains a cluster with members defined in two managed nodes running on two different machines. The cell also contains two unmanaged nodes running on HTTP servers with HTTP plug-in. Session persistence has been enabled.

  Which additional component(s) can the system administrator configure to make this environment highly available?

  A. Enable administrative security.
  B. Configure a DMZ secure proxy.
  C. Configure High Performance Extensible Logging.
  D. Configure primary and backup load balancers for the HTTP servers.
  C. Configure High Performance Extensible Logging.

• Question 27:

  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.
  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.

• Question 28:
