What happens when two aggregates are rejoined?

A.
It is not possible to rejoin aggregates.

B.
Data ONTAP will always retain data from the newest aggregate.

C.
Both aggregates revert to the last common snapshot before the split.

D.
You will have a large new aggregate containing all volumes from both aggregates.

E.
One of the aggregates will be overwritten and you will lose any data changed on it after the
split.

Explanation:
When you rejoin split aggregates, Data ONTAP mirrors the data from one aggregate to the other
and destroysdata that existed on that aggregate before the rejoin.
