Which attribute must be configured in indexes.conf on all peer nodes to activate replication for an index in an indexer cluster?

repFactor = 0
replicate = 0
repFactor = auto
replicate = auto

The correct answer is: repFactor = auto

To activate replication for an index in an indexer cluster, the attribute that needs to be configured is "repFactor." Setting it to "auto" allows Splunk to automatically determine the replication factor based on the cluster's available resources and configurations. This means that Splunk will dynamically manage the number of copies of data that need to be replicated across the peer nodes, ensuring data availability and redundancy without requiring manual intervention. When "repFactor" is set to "auto," it enables flexibility in managing the resources and can adapt to changes in the cluster, which is crucial for maintaining high availability and fault tolerance in data replication. This configuration is essential for ensuring that if a peer node fails or goes offline, the data will still be accessible from other nodes within the cluster, thereby maintaining system integrity and reliability. The other options provided do not correctly facilitate the activation of replication in an indexer cluster. Setting the replication factor to zero would disable replication entirely, while using a fixed numerical value would not leverage the adaptive capabilities of the indexer cluster.
