Which of the following is a method used for Disaster Recovery in Splunk?

The use of multisite clusters in Splunk is a robust method for disaster recovery that ensures data availability and redundancy across multiple geographic locations. In a multisite cluster, multiple indexers are deployed across different sites, meaning if one site experiences an outage or failure, the data and indexing capability can seamlessly continue to function from another site. This architecture provides a high level of fault tolerance and data protection.

Each site can store copies of the same data, allowing for reliable data retrieval and minimizing risks associated with total site failure. Additionally, the system can be designed to distribute user requests intelligently, improving performance and resilience in the event of a disaster at one location. Multisite clustering is essential in enterprises where continuous operation is critical, and data loss cannot be afforded.

Other methods mentioned, such as single-server architecture, standalone servers, and deployer use, do not provide the same level of redundancy and fault tolerance. Single-server architectures and standalone servers only operate from a single point of failure, which is not optimal for disaster recovery. The deployer, while useful for managing configurations across a Splunk environment, does not inherently provide disaster recovery capabilities on its own.
