Question 1

A system administrator needs to create a diagnostic trace for an application server which has a problem that occurs only infrequently. The desire is to limit the amount of space taken up by the trace output file but still ensure that the log includes the trace information recorded during the problem. What should the system administrator do to accomplish these goals?

A. Limit the Maximum Number of Historical Files to one.

C. Configure the trace output to use a memory buffer and do a manual dump when the problem occurs.
D. Reduce the Maximum File Size to an amount just larger than the required trace log.

Question 2

A system administrator isplanning to use Intelligent Management features in an existing cell with managed web servers running in the DMZ. The system administrator has created the On Demand Router (ODR) server, however, no traffic is routed to the application servers through the ODR. What should the system administrator configure to fix this issue?

A. Add web servers to the list of servers managed by the ODR, generate plugin-cfg.xml and copy to the web servers.
B. Regenerate plugin-cfg.xml file and copy to the web servers.
C. Add web servers to the list of servers managed by the ODR.
D. Add web servers as secure proxies for the ODR, generate plugin-cfg.xml and copy to the web servers.

Question 3
