IBM C9510-418 Online Questions & Answers

• Question 101:

  What can an administrator use to remotely manage multiple stand-alone (unfederated) application servers?

  A. Job Manager
  B. Administrative agent
  C. Deployment manager
  D. remoteServer.jacl script
  A. Job Manager

  ---

  Administering nodes remotely using the job manager In a flexible management environment, you can asynchronously submit and administer jobs for large numbers of stand-alone application servers, deployment managers, and host computers over a geographically dispersed area. At the remote machines, you can use jobs to manage applications, modify the product configuration, or do general purpose tasks such as run a script.

• Question 102:

  When adding a repository to a federated repository configuration, which type of repository can be added only using wsadmin commands?

  A. File repository
  B. LDAP repository
  C. SAML repository
  D. Database repository
  D. Database repository

  ---

  Federated repositories Supports multiple types of repositories such as file-based, LDAP, database, and custom. In WebSphere Application Server Version 8.5, file-based and LDAP repositories are supported by the administrative console. For database and custom repositories, you can use the wsadmin command-line interface or the configuration application programming interfaces (API).

• Question 103:

  Which of the following describes how communication occurs when a Web Services client sends a request to an application server?

  A. Through SOAP over HTTP and passing through the web services engine
  B. Through SOAP over JMS and passing through the embedded HTTP server
  C. Through RMI over IIOP communication directly to the messaging engine within the application server
  D. Through SOAP over JMS communications directly to the messaging engine within the application server
  D. Through SOAP over JMS communications directly to the messaging engine within the application server

• Question 104:

  An administrator has removed a node, but all the resources associated with the deleted node still exist. What can the administrator do to ensure the node configuration is removed from the cell repository?

  A. Run the command syncNoode.
  B. Refederate and remove the node.
  C. Run the command cleanupNode.
  D. Perform node synchronization via the Integrated Solutions Console.
  C. Run the command cleanupNode.

• Question 105:

  Which statement describes an administrative request to start a server in a cell topology?

  A. The admin application running on the node forwards the request.
  B. The request is sent to the web server running on the node agent.
  C. The request is sent to the admin service running on the node agent.
  D. The admin service running on the application server forwards the request.
  D. The admin service running on the application server forwards the request.

• Question 106:

  When recording a response file, what must be done to skip the install?

  A. Specify a response file location
  B. Specify the existing registry location
  C. Specify a temporary registry location
  D. Specify a master password repository
  B. Specify the existing registry location

• Question 107:

  What must be done to uninstall an application using the monitored directory functionality?

  A. Put a file named ApplicationName_delete in the monitored directory.
  B. Add a version of the application with no files inside of it to the monitored directory.
  C. Add a tag to the web.xml of the application, and add the file to the monitored directory.
  D. Add a properties file that has DELETE=true in the header of the properties sections, and add it to the monitored directory.
  B. Add a version of the application with no files inside of it to the monitored directory.

• Question 108:

  How can an administrator configure Web services security?

  A. Customize WS-Security policy set and bindings and attach to Web services.
  B. Configure global security with LDAP authentication and map the configuration to Web services.
  C. Request application developer to use Web Services Security API to achieve Web services security.
  D. Enable the Web Services Metadata Exchange (WS-MetadataExchange) protocol to enable message-level security.
  C. Request application developer to use Web Services Security API to achieve Web services security.

  ---

  The Web Services Security specification provides a flexible framework for building secure web services to implement message content integrity and confidentiality. The Web Services Security service programming model supports this flexible framework by providing extension points to integrate new token formats, and methods to obtains keys needed for message protection. The application server programming model provides Web Services Security programming application programming interfaces (WSS API) for securing SOAP messages.

  Note: WS-Security is a message-level standard that is based on securing SOAP messages through XML digital signature, confidentiality through XML encryption, and credential propagation through security tokens. The Web services security specification defines the facilities for protecting the integrity and confidentiality of a message and provides mechanisms for associating security-related claims with the message.

• Question 109:

  An administrator attempts an IBM Web Sphere Application Server package installation, but it fails. What must the administrator do before making another attempt?

  A. Uninstall IBM installation Manager and reinstall it.
  B. Use Installation Manager to uninstall everything under the package, and ignore any errors.
  C. Delete everything in the product directory before uninstalling the package using Installation Manager
  D. Restore a backup copy of the previous version of the product before using Installation Manager again.
  C. Delete everything in the product directory before uninstalling the package using Installation Manager

• Question 110:

  In an IBM WebSphere Application Server cluster, an administrator notices EJB requests are not evenly distributed on the cluster members during the load test. What two things can the administrator verify in order to identify and resolve the issue? (Choose two.)

  A. Ensure Dynamic Workload Management is enabled.
  B. Ensure host scoped routing optimization is enabled.
  C. Ensure PMI Workload Management counters are enabled.
  D. Ensure each server in the cluster has an equal weighted value.
  E. Ensure the Web server plug-in is using the round robin algorithm.
  A. Ensure Dynamic Workload Management is enabled.
  D. Ensure each server in the cluster has an equal weighted value.

  ---

  A: Workload management optimizes the distribution of client processing tasks. Incoming work requests are distributed to the application servers, enterprise beans, servlets, and other objects that can most effectively process the requests.

  D: The server weighted round robin routing policy ensures a balanced routing distribution based on the set of server weights that have been assigned to the members of a cluster. For example, if all servers in the cluster have the same weight, the expected distribution for the cluster is that all servers receive the same number of requests. If the weights for the servers are not equal, the distribution mechanism sends more requests to the higher weight value servers than the lower weight value servers. The policy ensures the distribution that you want, based on the weights that are assigned to the cluster members.
