What is required for search head redundancy in Splunk?

1. Two cluster members

2. Three cluster members

3. Four cluster members

4. One master node

The correct answer is: Three cluster members

In Splunk, search head redundancy is achieved through the use of multiple search heads within a search head cluster. A minimum of three cluster members is required to ensure proper redundancy and to maintain high availability. Having three search heads allows for a quorum to be established among the members. In this case, if one search head goes down, the other two can still maintain the functionality and provide service, preventing any downtime affecting users’ ability to search and analyze data. The design is such that it enables load balancing of search requests across the available members, facilitating both increased performance and fault tolerance. This configuration is essential for environments that require continuous uptime and reliability in their data search capabilities, making three cluster members the optimal minimum for achieving redundancy in a search head cluster.
