Question 7
The development group supplied you with the latest WAR file for the company web application. It has been thoroughly tested and needs to be placed into production.

C. SCAN is required for the GridLink data source to use an XA driver
C. Use the administration console. Select the machine, then the Configuration and Node Manager tabs. Select Enroll with the Domain. Save and activate your changes
