Question

Point out the wrong statement.

(a) The minimum requirements for a replica set are: A primary, a secondary, and an arbiter

(b) The primary is the only member in the replica set that receives write operations

(c) Most deployments, however, will keep three members that store data: A primary and two secondary members

(d) None of the mentioned

The question was posed to me by my college professor while I was bunking the class.

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

Answer 1

The correct option is (d) None of the mentioned

For explanation I would say: Secondary members replicate this oplog and apply the operations to their data sets.
