Hello everyone,
I recently took a trial test for websphere-340. i have no clue for the following questions. Could anyone of you please help me by giving answers to atleast some of these questions.It would be really helpful for me to prepare for the V5-340 test which i am about to take in the next week.
Thanks in advance.

13When enabling global security, which of the following is TRUE when using Local OS as the authentication mechanism?
(Select 2)
