What are the minimum requirements for deploying the Automatic Failover feature on Administration nodes in a distributed Cisco ISE deployment?

The correct answer is D. a primary and secondary PAN and a health check node for the Primary PAN. Cisco ISE's Automatic PAN Failover feature requires at minimum a Primary Administration Node (PAN), a Secondary Administration Node (PAN), and at least one health check node assigned to monitor the Primary PAN. The health check node continuously polls the Primary PAN's health; if

Explanation

Cisco ISE's Automatic PAN Failover feature requires at minimum a Primary Administration Node (PAN), a Secondary Administration Node (PAN), and at least one health check node assigned to monitor the Primary PAN. The health check node continuously polls the Primary PAN's health; if the Primary PAN becomes unreachable or fails its health checks, the health check node triggers automatic promotion of the Secondary PAN. The health check node is associated with the Primary PAN specifically, not the secondary, because its job is to detect when the primary has failed and initiate the failover process.
