Splunk Enterprise Certified Architect Practice Test

The role responsible for managing the indexer cluster in Splunk is the Master Node. This component is crucial within an indexer cluster because it oversees and manages various activities, such as ensuring that data is evenly distributed among the indexers, handling the replication of data, and coordinating the indexing processes. The Master Node also plays a significant role in maintaining cluster health and managing the cluster configuration, making it essential for the smooth operation and integrity of the data storage.

Other roles exist within the Splunk architecture, such as the Indexer, which is responsible for the actual indexing of data; the Deployer, which manages configurations across multiple instances; and the Monitoring Console, which provides monitoring capabilities and insights but does not manage the indexer cluster directly. The specific responsibilities of each role highlight why the Master Node is uniquely suited for managing indexer clusters effectively.
