第17题：

A customer stores environmental settings in the deployment descriptors of an application. Whenever they promote the application version from testing to the production environment, they need to open the archive and modify the deployment descriptor. This process is against their security policy.    What approach should you recommend to leverage WebLogic features such that they do not have to modify the application archive for different environments?（）
