Which of the following are deployment recommendations for ITSI?

[Reference: https://docs.splunk.com/Documentation/ES/latest/Install/DeploymentPlanning, A, B, and C are correct answers because ITSI deployments often require more hardware resources than base Splunk requirements due to the high volume of data ingestion and processing. ITSI deployments also require a dedicated search head that runs the ITSI app and handles all ITSI-related searches and dashboards. ITSI deployments may also increase the number of required indexers based on the number and frequency of KPI searches, which can generate a large amount of summary data.
