The sample test is designed to give the candidate an idea of the content and format of the questions that will be on the certification exam. Performance on the sample test is NOT an indicator of performance on the certification exam. This should not be considered an assessment tool.
To prepare for this test, it is first recommended that you are familiar with the job role description and the parameters this certification is based on, as well as have knowledge of the topics outlined in the test objectives/skills measured on the test. Compare your own technical level to the test objectives and the recommended training resources, and then determine for yourself how much preparation you require. Note that these educational sources are recommended, but not required (*) before taking a certification test.
Before preparing for the certification test, it is recommended that you measure your current level of skill by taking the Sample Test (located from the “Sample/Assessment test” link above)..
You can prepare for the test through the Tutor Approach (classroom, instructor led course, and other sources) or the Self-Study Approach. Sources within each approach collectively cover the skills measured on the test.
To prepare via the Tutor Approach, take course [WA855G or ZA855G], and refer to the sources with an * in front of them. Note that per this formula, you are only required to take 1 course.
To prepare via the Self-Study Approach, omit the course, and refer to all other sources with and without the * in front.
The recommended educational resources listed are not intended to be a substitute for, but should complement, relevant practical experience.
Extensive product knowledge is required to pass the test.
Every effort has been made to make the recommended educational resources as complete and as accurate as possible, but no warranty of fitness is implied. The resources provided are on an as is basis.

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?
A. Manually delete content from the directory.
B. During an update, create a new shared resources directory.
C. Clear the Delete Saved Files option for the Installation Manager.
D. Set the preserve Downloaded Artifacts preference to false.

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?
A. Use full repository checkpoints for both the backup and the restore.
B. Use the restore config command with -nostop for the restore.
C. Use the manage profiles command for both the backup and the restore.
D. Use the backup config command without -nostop for the backup Use the restore config command without -nostop for the restore.
Within a WebSphere Application Server Network Deployment cell, a system administrator needs to write a script to determine if a particular server is stopped. It is important that the wsadmin script explicitly return a status of stopped as opposed to just failing.
What wsadmin object should the administrator use to write this script?

The administrator needs to identify any security role references and security constraints in a web application.
How can the administrator identify these roles and constraints?
A. ibm-application-ext.xml file using a text editor.
B. ibmconfig folder in the application after using the EARExpander command.
C. Web deployment descriptor using IBM Assembly and Deploy Tools.
D. Security role to user/group mapping by using the Integrated Solutions Console (ISC).
