NEW QUESTION # 38
What is the purpose of elections in a replica set?

A. A mechanism to choose a new primary when the current primary is no longer available.
B. A mechanism to add new indexes to a running replica set.
C. A mechanism to add additional secondaries when the current secondaries are unavailable.
D. A mechanism for replicating data across all replica set members asynchronously.

Answer: A

Explanation:
Replica-set elections determine which eligible member serves as primary. An election can occur after the current primary becomes unavailable, after certain reconfigurations, during replica-set initialization, or when a primary is deliberately stepped down. Eligible voting members exchange election information and, when a candidate obtains the required support, that candidate transitions to primary and begins accepting writes.
Option A describes asynchronous replication through the oplog, which is a separate mechanism. Option C is unrelated: index creation is an administrative database operation, not a function of elections. Option D is also incorrect because elections do not add members to the replica-set configuration; adding a secondary requires an explicit membership change such as rs.add() or equivalent configuration management. Elections are the foundation of automatic failover and are one reason MongoDB replica sets can provide high availability without a human manually designating a replacement primary after every failure. During an election there can be a brief period in which writes are unavailable, so applications should use retryable behavior and appropriate driver topology handling. The purpose described in option B is therefore correct.
