What happens when two aggregates are rejoined?

The correct answer is E. One of the aggregates will be overwritten and you will lose any data changed on it after the split. When you rejoin split aggregates, Data ONTAP mirrors the data from one aggregate to the other and destroys data that existed on that aggregate before the rejoin. https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-B9CB3DA8-E1AF-4BAC-A85B- 64C009010F4A.html
