Demo Questions

Question 1

A system administrator completed a WebSphere Application Server installation by using the Installation Manager. During installation, all defaults were selected for the installation root directories and the shared resources directory. Over time, the administrator has updated the installation with various interim fixes and fix packs. 
The administrator notices that the shared resources directory is very large in size and grows larger each time the Installation Manager is run. 
How can the administrator decrease the size and remove some of the content from the shared resources directory?


  1. Manually delete content from the directory.
  2. During an update, create a new shared resources directory.
  3. Clear the Delete Saved Files option for the Installation Manager.
  4. Set the preserveDownloadedArtifacts preference to false.
Correct answer: D
Explanation:
Because product payloads are cached in this directory, space requirements can grow very large over the lifetime of the product, as service updates are applied. The WebSphere Application Server product image is large, so if this content is permitted to accumulate, then this directory will grow to be many gigabytes in size over the course of multiple fix pack applications. You should never manually delete the content in this folder. Instead, during any installation or maintenance operation, you can specify the following preference to remove some of the content in this folder:–preferences com.ibm.cic.common.core.preferences.preserveDownloadedArtifacts=false http://www-01.ibm.com/support/knowledgecenter/SSAW57_7.0.0/com.ibm.websphere.installation.soafepnd.doc/info/ae/ae/tins_installfp_dist.html?lang=en (Shared resources directory)

Question 2

A system administrator ran the backup Config command to backup the configuration using the -nostop option. The administrator changed the properties for the service integration environment by modifying the sib.properties file. During testing the administrator noticed Service Integration Bus related errors and wanted to restore the service integration environment. The administrator used the restore config command, but the tuning properties for the service integration environment were not restored. 
How can the administrator prevent this issue?


  1. Use full repository checkpoints for both the backup and the restore.
  2. Use the restore config command with -nostop for the restore.
  3. Use the manage profiles command for both the backup and the restore.
  4. Use the backup config command without -nostop for the backup Use the restore config command without -nostop for the restore.
Correct answer: B



Question 3

A system administrator wants to learn some of the Python scripting commands for the administration of the environment. 
Which product feature should the administrator use?


  1. The wsadmin.properties file to load a profile.
  2. The AdminTask object to generate wsadmin scripts.
  3. The guided activities panel from the Integrated Solutions Console (ISC).
  4. The "Log command assistance commands" option in the Integrated Solutions Console (ISC).
Correct answer: D



Question 4

A system administrator has created a Python script called globalScript. py. 
What should the administrator do to ensure globalScript. py is loaded when the wsadmin shell is used?


  1. Compile globalScript.py to a Java class in the bin directory.
  2. Invoke wsadmin with the argument-profileName globalScript.py.
  3. Modify the configureCustomProperty script to import globalScript. py.
  4. Set the script profiles in the wsadmin.properties file to load globalScript .py. 
Correct answer: D



Question 5

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:


  1. sas.client.props file.
  2. ssl.client.props file.
  3. soap.client.props file.
  4. wsadmin.properties file.
Correct answer: D



Question 6

A system administrator runs a Python script that creates and configures several servers and realizes 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?


  1. AdminApp.update ()
  2. AdminConfig.save()
  3. AdminControl.invoke(server, 'sync’)
  4. AdminTask.backupJobManager('server')
Correct answer: B
Explanation:



Question 7

A system administrator suspects that the slow performance of an application might be caused by lock contention. 
To debug this further, what can the administrator do using IBM Support Assistant?


  1. Analyze the running server using IBM Monitoring and Diagnostic Tools for Java – Health Center.
  2. Collect a javacore and analyze it using IBM Monitoring and Diagnostic Tools for Java – Health Center.
  3. Collect three thread dumps at equal time intervals and analyze them using IBM Monitoring and Diagnostic Tools for Java – Dump Analyzer.
  4. Collect three system dumps at equal time intervals and analyze them using IBM Monitoring and Diagnostic Tools for Java – Memory Analyzer.
Correct answer: A
Explanation:
The IBM Monitoring and Diagnostic Tools for Java - Health Center is a lightweight tool that monitors active IBM Virtual Machines for Java with minimal performance overhead. The Health Center suggests live tuning recommendations for Garbage Collection, profiles methods including call stacks, and highlights contended locks. This information can help you optimize performance, improve stability and optimize system resource usage. The tool is provided in two parts:An agent, which collects data from a running application. Java applications are monitored by the Health Center agent The Health Center client, an Eclipse-based GUI which connects to the agent. The client interprets the data that is obtained by the agent and provides recommendations to improve the performance of the monitored application. The client is available as an Eclipse plug-in and as part of IBM Support Assistant (ISA). References: https://www.ibm.com/support/knowledgecenter/SS3KLZ/com.ibm.java.diagnostics.healthcenter.doc/homepage/plugin-homepage-hc.html

Question 8

A system administrator was asked by the development team to inform them of any warning message which contains a string “Connection” on a WebSphere Application Server with High Performance Extensible Logging (HPEL) enabled. 
What should the administrator do to continuously monitor logs for the required message?


  1. Configure log detail levels to include filter on “Connection” string.
  2. Use the Log Viewer in the administrative console with filter on “Connection” string.
  3. Use the logviewer.sh or logviewer.bat command with appropriate options. 
  4. Use the Log Viewer in the administrative console with filter on “Connection” string and enable the “Refresh automatically” feature.
Correct answer: C
Explanation:
The High Performance Extensible Logging (HPEL) facility writes to the log and trace repositories in a binary format. You can view, query and filter the repository using the LogViewer command. logviewer.sh -monitor -includeLoggers Connection -monitor [integer] Specifies that you want the logViewer to continuously monitor the repository and output new log record entries as they are created. You can provide an optional integer argument after this parameter to specify how often you want the LogViewer tool to query the repository for new records. By default the logViewer queries the repository for new records every 5 seconds. When used with other filtering options, only those new records that match the filter criteria are displayed. References: https://www.ibm.com/support/knowledgecenter/en/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/rtrb_logviewer.html

Question 9

A system administrator needs to trigger a javacore only when a java,net.SocketTimeoutException is encountered in real time. 
What does the administrator have to configure to trigger the javacore dump?


  1. Configure the JAVA_DUMP_OPTS environment variable to capture javacore for ANYSIGNAL and all exceptions.
  2. Configure an –Xdump:java Generic JVM argument on WebSphere Application Server with the filter for java.net.SocketTimeoutException.
  3. Code wsadmin script to capture javacore and then execute it after the java.net.SocketTimeoutException has been encountered.
  4. Use the log filter in HPEL to monitor for java.net.SocketTimeoutException and then gather a javacore dump from the Integrated Solutions Console (ISC).
Correct answer: B
Explanation:
Dump agents are set up during JVM initialization. They enable you to use events occurring within the JVM, such as Garbage Collection, thread start, or JVM termination, to initiate one of four types of dump or to launch an external tool. Default dump agents are set up at JVM initialization They are sufficient for most cases, but the use of the -Xdump option on the command line allows more detailed configuration of dump agents. The total set of options and sub-options available under -Xdump is very flexible and there are many examples presented in this chapter to show this flexibility. Example: To generate system cores:-Xdump:system:events=userReferences: http://www-01.ibm.com/support/docview.wss?uid=swg21242497
