Which of the following will trigger a data collector election? (Choose
all that apply.)

A.
A member server loses contact with the data collector.

B.
A server is brought online within the server farm.

C.
A member server is brought down within the server farm.

D.
The data collector goes offline.

Explanation:
Events that will trigger a data collector election are a member server losing contact with the data collector, the
data collector
going offline, a server being brought online within the server farm, invoking the querydc -e command, or the
zone configuration changing.
Bringing down a member server that is not a data collector will have no effect on election criteria.
