Which three statements are true about the Change Center in administration console?

Which three statements are true about the Change Center in administration console?

A.
The Change Center has a link to view the changes made so far.

B.
The Change Center is available only in a Production Mode domain.

C.
The Change Center has a link to view any servers that need to be restarted.

D.
After activating the changes to a server’s configuration, you must always restart that server.

E.
In a Development Mode domain, the configuration lock can be acquired automatically.

F.
Changes must always be activated before they can be undone.

Explanation:
A: You can view any changes that you have saved, but not yet activated, by clicking
the View Changes and Restarts link in the Change Center.
C: The View Changes and Restarts link presents two tabs, Change List and Restart Checklist:
* The Change List tab presents all changes that have been saved, but not yet activated.
* The Restart Checklist lists all servers for which non-dynamic changes have been activated, but
which require restarts before the changes become effective.
Incorrect:
D: is wrong because dynamic changes usually don’t require a restart if that is all that was
changed. If it were mix of dynamic and non-dynamic changes it would require a restart.
F: is wrong because in production mode the change center has the “undo all changes” button so
you don’t have to activate the changes before you undo them.
