During the integration of ISE and DNA Center, which of the following are used to establish trust through ISE?

REST APIs are used for general programmatic interaction and configuration, but pxGrid is specifically designed for the secure context sharing and trust relationship between security platforms like ISE and DNA Center.

pxGrid (Platform Exchange Grid) is the foundational service used to establish trust and facilitate contextual information exchange between Cisco ISE and Cisco DNA Center. This open and secure platform allows ISE to share identity, policy, and security posture data with DNA Center, enabling coordinated security operations and policy enforcement across the network.

Scalable groups (SGTs) are used for defining policy groups within ISE for segmentation purposes, not for establishing system-to-system trust between ISE and DNA Center.

SGACLs (Scalable Group Access Control Lists) are access control policies enforced based on SGTs, used for network segmentation, not for establishing trust between security platforms.
