What is the purpose of a split-brain handler in DRBD?

To automatically resolve a split-brain situation by discarding data from one node.

To log split-brain events for later analysis.

To prevent split-brain from ever occurring.

To merge the data from both nodes.

A two-node Pacemaker cluster uses DRBD as the replicated storage for a critical database. The cluster must never run the database on both nodes simultaneously, even during a network partition. The administrator wants to configure DRBD to automatically resolve split-brain scenarios by killing the node that is not part of the current quorum. Which DRBD configuration option should be used?

fencing handler that calls a Pacemaker fence agent

split-brain handler that automatically discards data on the secondary

quorum setting with a minimum of 2 votes

reconnect interval set to a very low value
