Splunk Enterprise Certified Architect Practice Test

In the context of setting up Enterprise Security on a Search Head Cluster, it's crucial to have the Enterprise Security software installed on the deployer. The deployer is responsible for managing the distribution of apps and configurations to the various search heads within the cluster.

By installing the Enterprise Security software, you ensure that all necessary components, dashboards, and knowledge objects specific to Enterprise Security are available for the search heads. This not only streamlines the deployment process but also guarantees that the search heads have the full functionality of Enterprise Security, enabling effective security monitoring and analytics.

The other options, while part of the overall Splunk ecosystem, do not focus on the core requirement for successfully integrating Enterprise Security with the search head cluster. Common apps and configurations are naturally important, but without the core Enterprise Security software, the functionalities and features of the application would be incomplete. Similarly, while keeping Splunk updated is vital for stability and performance, it doesn’t specifically address the immediate need for Enterprise Security in this scenario.
