Which Cisco ISE deployment model provides redundancy by having every node in the deployment configured with the Administration. Policy Service, and Monitoring personas to protect from a complete node failure?

A two-node Cisco ISE deployment is specifically designed for high availability and redundancy in small to medium-sized networks. In this model, both nodes are configured to run all three primary personas: Administration, Policy Service, and Monitoring. One node is designated as the Primary Administration Node (PAN) and Primary Monitoring Node (MnT), while the other is the secondary. Both nodes actively handle policy requests as Policy Service Nodes (PSN). If the primary node fails, the secondary node can be promoted to take over the administration and monitoring functions, ensuring complete service continuity.

A. distributed: This is a general term for a multi-node deployment, which typically separates personas onto dedicated nodes for scalability, rather than having all personas on every node.
B. dispersed: This is not an officially recognized term for a standard Cisco ISE deployment model.
D. hybrid: This is not an officially recognized term for a standard Cisco ISE deployment model.

1. Cisco Identity Services Engine Administrator Guide

Release 3.1

"Set Up a Cisco ISE Deployment

" Section: "Cisco ISE Deployment Models."

This section explicitly describes the two-node deployment: "You can have a deployment with two Cisco ISE nodes where one node functions as the primary and the other as the secondary. In a two-node deployment

both the nodes can run all the personas."

Release 3.0

"Set Up a Cisco ISE Deployment

" Section: "Cisco ISE Deployment Models."

This guide provides a similar description

stating for a two-node setup: "In this type of deployment

both the nodes can assume any of the personas." It further clarifies that this setup provides a failover mechanism for the Administration and Monitoring functions.
