Which of the following is NOT a customer responsibility in Splunk Cloud?

In Splunk Cloud, the responsibilities of the customer are clearly defined to allow users to manage their data and configurations effectively while Splunk takes care of the underlying infrastructure and platform management.

Configuring Splunk Cloud network for high availability is indeed a responsibility that lies with Splunk, not the customer. This aspect involves ensuring that the cloud infrastructure supports continuous uptime and can handle failover scenarios. The Splunk Cloud platform is designed to provide managed services, including network configuration and operational integrity, leaving customers free to focus more on data ingestion, user management, and utilizing the platform’s features.

On the other hand, authenticating users, managing configurations such as sourcetypes, and forwarding data to Splunk Cloud are all customer responsibilities. Users must control their own authentication processes to secure access to the data. They are also tasked with configuring their data inputs, including defining sourcetypes, which helps in the proper indexing and searching of logs. Forwarding data to Splunk Cloud involves ensuring that relevant data sources are connected and streaming data properly into the Splunk environment.

Thus, the correct answer emphasizes that high availability configurations are part of Splunk's managed service offering and not a responsibility placed upon the customer.
