IBM IBM Certifications C9510-418 Questions & Answers

• Question 91:

  What is the main difference between interim fixes and product fix packs as they relate to IBM WebSphere Application Server?

  A. Interim fixes typically contain new features or functionality ahead of future product fix packs.

  B. Product fix packs are a combination of interim fixes and internal fixes to make patching easier.

  C. Product fix packs are generally reserved for new features or functionality whereas interim fixes are provided only to fix known issues.

  D. Product fix packs bring WebSphere Application Server to a new product level whereas interim fixes provide corrective service for specific known problems.

  Correct Answer: D

  Product fix packs contain bundled service to bring WebSphere Application Server up to a new product level. Interim fixes provide corrective service for specific known problems.

• Question 93:

  To write a Jython script to stop a running application server, an administrator should use which administrative object?

  A. AdminApp

  B. AdminTask

  C. AdminConfig

  D. AdminControl

  Correct Answer: D

  You can use the wsadmin tool to stop applications.

  There are two ways to complete this task. Firstly, you can use the AdminControl object to stop the

  application. Alternatively, you can use the scripts in the AdminApplication script library to start, stop, and

  administer your application configurations.

• Question 94:

  Which of the following is a prerequisite for configuring single sign-on for authentication using LTPA cookies?

  A. All server must use the same IBM HTTP Server.

  B. All servers must be configured as part of the same DNS domain.

  C. All servers must use an IBM Domino Directory that is configured for LDAP access.

  D. All servers must be managed by the same IBM WebSphere Application Server Deployment Manager.

  Correct Answer: B

  To take advantage of support for SSO between WebSphere Application Servers or between WebSphere Application Server and a Domino server, applications must meet the following prerequisites and conditions:

  *

  Verify that all servers are configured as part of the same DNS domain.

  *

  Etc.

• Question 95:

  When enabling SSL directives in the IBM HTTP Server configuration file, which parameter is required?

  A. The name of the key file

  B. The AllowOverride statement

  C. The IP address of the VirtualHost

  D. The DocumentRoot directory path

  Correct Answer: A

  Enable SSL and define a key file to use. Uncomment the following lines to enable SSL and define a key file to use: SSLEnable SSLServerCert default Keyfile "C:/Program Files/IBM/HTTPServer5/conf/admin.kdb"

• Question 96:

  What determines which On Demand Routers (ODRs) a Web server forwards requests to?

  A. The default order in the ODR_Module_Routing_Poilicy.xml.

  B. The configuration scope determines which ODRs are included in httpd.conf.

  C. The configuration scope determines which ODRs are included in plugin-cfg.xml.

  D. The configuration scope determines which ODRs are included in HTTPplugin-cfg.xml.

  Correct Answer: C

  In a topology with a web server which forwards requests to an on demand router (ODR), the ODR can be set to dynamically generate and update the web server plug-in configuration file plugin-cfg.xml. By configuring an ODR to dynamically update plugin-cfg.xml, you avoid manually updating the file during administrative actions, which can affect the content.

• Question 97:

  Which type of fix would typically be downloaded to address a specific problem?

  A. Interim fix

  B. Cumulative fix

  C. Product fix pack

  D. Cumulative interim fix

  Correct Answer: A

  A WebSphere Commerce interim fix (iFix) is a software patch that contains fixes for one or more APARs. A WebSphere Commerce cumulative iFix is a comprehensive collection of interim fixes for a specific release. Both types of fixes are installed with the WebSphere Commerce Update Installer (UPDI).

  Note: An Authorized Program Analysis Report, or APAR, is a formal report from IBM development to customers that have notified IBM of a problem or suspected defect. If IBM development is able to confirm the existence of the issue they will create an APAR with any known work around and perhaps an indication of which future release, if any, of the IBM program they intend to target for a formal fix to the defect and whether or not a Program Temporary Fix (PTF) is planned. The APAR will then be published so that it is visible to supported customers.

• Question 98:

  In addition to logging changes, what can Cross Component Trace capture?

  A. The user agent of the browser that has initiated the request.

  B. The last time that the component was updated by a code deploy.

  C. The time that the component was started in the application server.

  D. Data snapshots that store entire request and response bodies on the file system.

  Correct Answer: C

  Cross Component Trace (XCT) annotates the logs so that log entries that are related to a request that is

  serviced by more than one thread, process, or even server are identified as belonging to the same unit of

  work.

  XCT log records are typically added to the logs to:

  demarcate the beginning and ending of work for a particular request on a particular thread.

  demarcate when work is about to be transferred to another thread or process, or to indicate when work

  returned from another thread or process.

  demarcate when work moves from major component to major component, even if work continues on the

  same thread; for example to show transfer of control from application server code to application code.

• Question 99:

  Which of the following statements is true regarding the relationship of nodes and node groups?

  A. Nodes can belong to only one node group.

  B. Nodes managed by a node group cannot be deleted.

  C. All nodes are initially not associated with a node group.

  D. All nodes are initially associated with a default node group.

  Correct Answer: D

  D: a node must be a member of a node group. Initially, all Application Server nodes are members of the default DefaultNodeGroup node group.

  Note: A node group is a collection of managed nodes.

  Incorrect Answers:

  A: A node can be a member of more than one node group.

  C: A node must be a member of a node group. Initially, all Application Server nodes are members of the default DefaultNodeGroup node group.

• Question 100:

  How can the administrator change the console session expiration for the Integrated Solutions Console?

  A. Modify timeout value and run the timeout.jacl script.

  B. Set the timeout value in the Console Preferences panel.

  C. Use the settimeout wsadmin command and specify the value.

  D. Set the ConnectionResponseTimeout value in the Integrated Solutions Console.

  Correct Answer: A

  Change the on the two lines of the timeout.jacl script to the new session expiration value. This number specifies the number of minutes the console preserves the session during inactivity.
