True or False: Cloud authentication supports DUO two-factor authentication.

In the context of Splunk Cloud, cloud authentication does not support DUO two-factor authentication. This means that users cannot utilize DUO as a second factor for authentication in a Splunk Cloud environment. This limitation is significant for organizations that rely on DUO to enhance security through two-factor authentication for their applications.

Other options present various conditions that either imply potential support or that such a feature may be available under specific scenarios, none of which are applicable in this instance since the direct support for DUO is not established in Splunk Cloud. Therefore, understanding the security mechanisms supported by Splunk Cloud is crucial for organizations planning to implement authentication measures.
