What are the three authentication protocols offered by Splunk Cloud?

The correct choice identifies the three authentication protocols supported by Splunk Cloud: Splunk native, SAML, and LDAP.

Splunk native authentication allows users to manage their own user IDs and passwords directly within the Splunk interface. This method is straightforward and provides a basic level of security suitable for smaller environments.

SAML, or Security Assertion Markup Language, is an industry-standard protocol that enables single sign-on (SSO) capabilities. This allows users to authenticate once and gain access to multiple applications without needing to log in to each one individually, enhancing user experience and security.

LDAP, which stands for Lightweight Directory Access Protocol, is used for accessing and maintaining distributed directory information services. It allows integration with existing directory services, making it easier to manage user access based on organizational structures.

While the other options include various protocols, they either do not align with the supported authentication mechanisms in Splunk Cloud or include protocols that are not relevant to the platform's design and functionality.
