Question

__________ sets the member that this replica set member will sync from, overriding the default sync target selection logic.

(a) rs.reconfig()

(b) rs.remove()

(c) rs.stepDown()

(d) rs.syncFrom()

I had been asked this question by my school teacher while I was bunking the class.

I want to ask this question from Replication Processes in section Replication Concepts, Processes and Replication Set of MongoDB

Answer 1

Right choice is (d) rs.syncFrom()

The explanation is: rs.syncFrom() provides a wrapper around the replSetSyncFrom, which allows administrators to configure the member of a replica set that the current member will pull data from.
