• Question 103:

  Which of the following is true about certificate expiration monitoring?

  A. Must be run manually.

  B. Must be run on the deployment manager.

  C. Deletes the certificates after they are expired, but does not replace them.

  D. Can replace expired certificates or certificates in the expiration threshold with a new certificate

  Correct Answer: D

  Certificate monitor configuration settings can be configured on the administrative console by selecting Security > SSL certificate and key management > Manage certificate expiration. . On the Manage certificate expiration panel, you can perform the following functions. Set the expiration threshold in the box labeled Expiration replacement threshold. The expiration replacement threshold is the number of days before a certificate expiration that a certificate can be replaced and has a default value of 60 days. Delete the certificates after they are replaced by selecting the Delete expiring certificates and signers after replacement box. This box is selected by default. Etc.

• Question 104:

  An administrator is using the Guided Troubleshooter in the IBM Support Assistant to troubleshoot IBM WebSphere Application Server issues. After going through data collection and analysis, no reliable solution is found.

  What is the administrator's best next step?

  A. Call in a new PMR with IBM and upload Troubleshooter data to ECuREP.

  B. Open a new PMR with IBM and upload SystemOut.log from the IBM WebSphere Application Server.

  C. Submit results to the IBM WebSphere Application Server forum for a quick response from other forum users.

  D. Use the Guided Troubleshooter to open a service request with IBM, so all the troubleshooting data analyzed so far is uploaded automatically.

  Correct Answer: D

• Question 105:

  When installing IBM WebSphere Application Server on a network file system, IBM Installation Manager fails with an insufficient disk space error.

  How could this be resolved?

  A. Increase disk space and try again.

  B. Delete temporary files and try again.

  C. Reboot operating system and try again.

  D. Disable disk space checking in the config.ini and try again.

  Correct Answer: D

  On some network file systems, disk space might not be reported correctly at times; and you might need to bypass disk-space checking and proceed with your installation. To disable disk-space checking, specify the following system property in the config.ini file in IM_install_root/eclipse/configuration and restart Installation Manager.

• Question 106:

  When installing a new application to IBM WebSphere Application Server, which location is valid for the application file?

  A. Client Machine

  B. Managed Node

  C. Unmanaged Node

  D. Remote Web Server

  Correct Answer: B

  Configuration file location during application installation

  Several things occur upon installation of an application onto WebSphere Application Server:

  The application binaries and deployment descriptors are stored within the master repository.

  The application binaries and deployment descriptors are published to each node that will host the

  application. These files are stored in the local copy of the repository on each node.

  Each node then installs the applications that are ready for execution by exploding the EARs under

  profile_root/installedApps/cell_name/, as follows:

  -profile_root/installedApps/cell_name/

  This directory contains a subdirectory for each application deployed to the local node.

  -profile_root/installedApps/cell_name/app_name.ear/

  Each application-specific directory contains the contents of the original EAR used to install the application.

  Note: A node is a logical grouping of managed servers. Nodes can be managed or unmanaged. An unmanaged node does not have a node agent or administrative agent to manage its servers, whereas a managed node does. Both application servers and supported web servers can be on unmanaged or managed nodes.

• Question 107:

  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.

  Correct Answer: C

  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 108:

  A system administrator has just enabled HPEL in the environment.

  How can the administrator examine the logged data?

  A. Use the ViewLog command.

  B. Use the administrative console.

  C. Use a text editor to open the systemOut.log file.

  D. Use the IBM Support Assistant to analyze the text log.

  Correct Answer: B

  High Performance Extensible Logging (HPEL) is a log and trace facility that is provided as a part of WebSphere?Application Server. HPEL provides a log data repository, a trace data repository, and a text log file. The HPEL LogViewer is an easy-to-use, command-line tool provided for HPEL users to work with the log data and trace data repositories. Use the following command to view the full contents of your log and trace repositories: [Windows] (Windows) logViewer.bat [AIX HP-UX Solaris] (Unix- full profile) logViewer.sh [AIX HP-UX Solaris] (Unix- Liberty profile) logViewer

• Question 109:

  An administrator needs to resolve port conflicts after creating a managed node using the Profile Management Tool.

  Which supported method can be used to resolve the port conflicts?

  A. Edit serverindex.xml.

  B. Use updatePorts.ant.

  C. Use Profile Port Checker tool and set ports.

  D. Use manageProfile tool and set port range on the profile.

  Correct Answer: B

  If you discover ports conflicts, then you can reassign ports manually. To reassign ports, run the updatePorts.ant file by using the ws_ant script.

• Question 110:

  What is one way to determine if administrative security for IBM WebSphere Application Server is disabled when logging into the Integrated Solutions Console?

  A. A user is not forced to use HTTPS (SSL).

  B. An administrator is allowed to type any random password.

  C. An administrator is prompted for user name, but not password.

  D. When the username wasadmin is used to log in, the password used is the default "password".
