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?
Answer(s): C
Which Cisco ISE deployment model is recommended for an enterprise that has over 50,000 concurrent active endpoints?
What is a restriction of a standalone Cisco ISE node deployment?
After you install a Cisco ISE node, all the default services provided by the Administration, Policy Service, and Monitoring personas run on it. This node is in a standalone state. You must log in to the Admin portal of the Cisco ISE node to configure it. You cannot edit the personas or services of a standalone Cisco ISE node. You can, however, edit the personas and services of the primary and secondary Cisco ISE nodes. You must first configure a primary ISE node and then register secondary ISE nodes to the primary ISE node.

What are the minimum requirements for deploying the Automatic Failover feature on Administration nodes in a distributed Cisco ISE deployment?
Answer(s): D
In a high availability configuration, the Primary Administration Node (PAN) is in the active state. The Secondary PAN (backup PAN) is in the standby state, which means it receives all configuration updates from the Primary PAN, but is not active in the ISE network.Cisco ISE supports manual and automatic failover. With automatic failover, when the Primary PAN goes down, an automatic promotion of the Secondary PAN is initiated. Automatic failover requires a non-administration secondary node, which is called a health check node. The health check node checks the health of Primary PAN. If the health detects that the Primary PAN is down or unreachable, the health check node initiates the promotion of the Secondary PAN to take over the primary role.To deploy the auto-failover feature, you must have at least three nodes, where two of the nodes assume the Administration persona, and one node acts as the health check node. A health check node is a non- administration node and can be a Policy Service, Monitoring, or pxGrid node, or a combination of these. If the PANs are in different data centers, you must have a health check node for each PAN.

Julio Commented on January 02, 2025 I want to share my feedback about this study guide. The exam is very very hard. I have been preparing for almost 3 weeks now and finally wrote my exam today and passed. This exam prep course is one of the best I have ever used. Worth the cost and the time you save. Mexico
Qorban Commented on April 11, 2021 I paid in Derham and the process of payment and download was so fast and easy. The Test Engine called Xengine App came for free. I am stdying from that engine. For now I am not ready yet. But ones I go do my test I come back and write my score here so others can a more informed decision. UNITED ARAB EMIRATES
