A WebLogic team is developing an enterprise application from their desktop WebLogic environment. All development systems are connected to the same eight data sources for testing. As a WebLogic Administrator supporting this team, which two actions should you perform to free the developers from creating and configuring all the data sources on their desktop WebLogic environment?

WebLogic Administrators typically use the Administration Console or the WebLogic Scripting Tool (WLST) to create and deploy (target) JDBC modules.
Note:
* (not A) Domain template—defines the full set of resources within a domain, including infrastructure components, applications, services, security options, and general environment and operating system options.
* Extension template—defines the applications and services that you can add to an existing domain, including product component functionality and resources such as JDBC or JMS.
* (not B) Each domain describes its configuration in an XML document that is located in the domain’s configuration directory. At run time, each WebLogic Server instance in a given domain creates an in- memory representation of the configuration described in this document. The central configuration file for a domain is DOMAIN_NAME/config/config.xml. This file specifies the name of the domain and the configuration of each server instance, cluster, resource, and service in the domain. The file includes

to additional XML files that are stored in subdirectories of

theDOMAIN_NAME/config directory. These included files are used to describe major subsystems of

WebLogic Server.
