An engineer is designing a new distributed deployment for Cisco ISE in the network and is considering failover options for the admin nodes. There is a need to ensure that an admin node is available…

A Cisco ISE distributed deployment requires a primary Administration Node and a secondary Administration Node to provide high availability for configuration and monitoring services. If the primary admin node fails, the secondary node can be promoted to primary, ensuring that policy configuration capabilities remain accessible without interruption.

A Policy Service Node handles authentication and authorization, not admin configuration, so pairing it with a secondary admin node does not provide full admin redundancy.

A Policy Service Node handles authentication and authorization, and a Monitoring and Troubleshooting Node collects logs and reports; neither provides high availability for admin configuration.

While a primary admin node is necessary, a Monitoring and Troubleshooting Node does not provide redundancy for administration services; its role is data collection and reporting.
