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 is configuring the security of a new environment. The administrator has been asked to configure one LDAP server that has different sub-trees for business users and administration users. 
What should the administrator do to implement the required security configuration?


  1. Install and configure a TAI (Trust Association Interceptor)
  2. Configure a security domain for the stand-alone LDAP server.
  3. Use Federated repositories and configure the supported entity types.
  4. Use Stand-alone custom registry and configure the flat file implementation.
Correct answer: C
Explanation:
Select the type of user registry that you need for your environment:Federated repositories: Manage identities that are stored in multiple repositories in a single, virtual realm.Standalone LDAP Server: Uses the Lightweight Directory Access Protocol (LDAP) user registry settings. Select this option in case your users and groups reside in an external LDAP registryLocal operating system: Uses the local operating system user registry of the application server.Standalone custom registry: Specifies a custom registry that implements the UserRegistry interface in the com.ibm.websphere.security package.References: WebSphere Application Server V8.5 Administration and Configuration Guide for the Full Profile (July 2013), page 212

Question 4

A system administrator has added a server cluster as a member of a service integration bus (SIB). The administrator needs to configure one messaging engine for each server in this cluster and to have a failover location for each messaging engine. 
What should the administrator do to achieve the required design?


  1. Configure a new messaging engine in each server to support failover.
  2. Configure the data store for each messaging engine for each server in the cluster.
  3. Select scalability with high availability as the messaging engine policy.
  4. Create a core group policy to restrict each messaging engine to a particular server.
Correct answer: C
Explanation:
The scalability with high availability configuration ensures that there is a messaging engine for each server in a cluster, and that each messaging engine has a failover location.   http://www-01.ibm.com/support/knowledgecenter/SSCKBL_8.5.5/com.ibm.websphere.nd.doc/ae/cjt1004_.html (second paragraph)

Question 5

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 6

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 7

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 8

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: C



Question 9

An application deployed to a multi-node cluster is reported to have slowness and hung threads. A system administrator is asked to review the logs on each node and identify if the hung threads are a false alarm. 
How can the administrator determine that the hung threads are a false alarm? 
Analyze the:


  1. ffdc logs
  2. SystemErr.log
  3. SystemOut.log
  4. native_stderr.log
Correct answer: C
Explanation:
Problem(Abstract) The SystemOut.log contains a WSVR0605W message, also called a hung thread message. A javacore, or thread dump on Solaris and HP-UX, is needed in order to determine how to resolve the potentially hung threads. Cause WebSphere Application Server attempts to report potentially hung threads using the hung thread detector. Depending on how the hung thread detector policy is configured, a thread running for a certain interval (default 10 minutes) might be reported as hung and a WSVR0605W message is printed in the SystemOut.log file:WSVR0605W: Thread <threadname> has been active for <time> and may be hung.  There are <totalthreads> in total in the server that may be hung.References: https://www-01.ibm.com/support/docview.wss?uid=swg21448581

Question 10

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
