QUESTION 1
You have an application already deployed in a production environment that needs a modification to one of its tuning
parameters. Currently, that tuning parameter has a default value since there was neither a deployment descriptor used nor
a deployment plan included with the application deployment. You now attempt to use the Administration Console web
application to make a dynamic modification to that parameter.

Which statement is true? (Choose the best answer.)

A. A new deployment plan will be generated and saved at the indicated location.
B. The modification attempt will fail because there is no deployment descriptor included within the application.
C. The modification attempt will fail because there is no existing deployment plan associated with the application.
D. A new skeleton plan.xml will be generated if a plan folder is detected with the deployed application.

Answer: D

Explanation:
Defining tuning parameters is not required in order to successfully deploy an application. If an application’s deployment
descriptors and deployment plan do not define tuning parameters, WebLogic Server uses default values. The
Administration Console automatically uses a deployment plan named plan.xml in the \plan subdirectory of an application
root directory if one is available.

QUESTION 2
You are creating a Domain Template to simplify the process of deploying a domain across multiple hosts.
Which five types of information can be included in a Domain Template? (Choose five.)

A. domain configuration, those included in the config.xml file
B. Java Enterprise Edition (Java EE) applications and shared libraries
C. Windows and UNIX server start scripts
D. Windows Start menu entries
E. custom folders and files
F. LDAP data
G. JTA log
H. e-mail notification settings

Answer: A,B,C,D,E

Explanation:
A: config.xml and any JDBC and JMS resources defined in config.xml are not displayed in the Current Template View pane by default because the Domain Template Builder automatically includes them in the template when creating the template.
B: The Add or Omit Applications screen is displayed only if applications are included in the template or domain that you selected.
C: When you are creating a template, you want the scripts and files that you are packaging with your template to be free of local domain environment settings and ready for use by the Configuration Wizard. The Domain Template Builder automatically updates any standard scripts included in a template (such as start scripts) by replacing hard-coded values for various domain environment settings with replacement variables.
D: The Specify Start Menu Entries screen prompts you to create items to be added to the Windows Start menu.
E: By default, the Domain Template Builder includes files from the WebLogic domain or template you specified as the source for the new template. If you selected a domain as the source for your new template, some files and directories are included automatically.

QUESTION 3
Examine the domain diagram:
What is the correct path within the configuration hierarchy to the MBean that contains the log rotation parameters for server04? (Choose the best answer.)

A. B. /server04/log/rotation
B. C. /Cluster01/server04/log
C. /Machine02/server04/log
D. E. /Logs/server04
E. /TestDomain/server04/log
F. /server04/log

Answer: D

Explanation:
By default, the rotated files are stored in the same directory where the log file is stored.
The server log file is located on the computer that hosts the server instance. By default, the server log file is located below the server instance’s root directory: root-directory\server-name\server-name.log.
