Designing High Availability Indexer Clusters in Splunk

What configurations are supported in single-site and multi-site indexer clusters?

A. Active-passive configuration

B. Active-active configuration

C. Both

Answer:

Both single-site and multi-site indexer clusters can support active-passive or active-active configurations for high availability and load distribution.

Active-passive and active-active configurations are essential for setting up distributed systems for high availability and load balancing, especially in indexer clusters within systems like Splunk.

In a single-site indexer cluster, the active-passive configuration involves one primary node handling all the indexing processes, with other nodes in standby mode ready to take over in case of primary node failure. On the other hand, the active-active configuration distributes the load among all nodes in the cluster.

For multi-site indexer clusters that span across multiple physical locations, both active-passive and active-active configurations can be implemented. This setup allows for geographical redundancy and disaster recovery, ensuring continuous operations even in the event of site failures.

Therefore, the best answer to the question is C. Both single-site and multi-site indexer clusters can support active-passive or active-active configurations, providing high availability and optimal resource utilization in various scenarios.
