Question 1
A Cisco ISE operations team investigates this site issue: A three-campus deployment combines the policy administration function and every access request on one node; policy edits during a scheduled restart interrupt all 802.1X sessions. Which administrative action BEST addresses this specific situation?
Explanation
Correct Answer
Separate central Policy Administration Node responsibilities from appropriate Policy Service Nodes, and distribute RADIUS requests to healthy PSNs. This is appropriate because the PAN manages configuration while PSNs process live network-access authentication; co-locating them creates a common maintenance failure point. It should be verified by this evidence: During a PAN maintenance test, already provisioned PSNs continue making permitted RADIUS decisions using their synchronized policy.
Incorrect Answers
A distributed ISE deployment has explicit primary configuration ownership; multiple unsynchronized primaries do not form a valid replicated policy set. The actual fault is governed by a different mechanism: the PAN manages configuration while PSNs process live network-access authentication; co-locating them creates a common maintenance failure point. The needed response is: Separate central Policy Administration Node responsibilities from appropriate Policy Service Nodes, and distribute RADIUS requests to healthy PSNs.
The Monitoring persona collects operational and reporting data, distinct from PSNs answering live AAA requests. The actual fault is governed by a different mechanism: the PAN manages configuration while PSNs process live network-access authentication; co-locating them creates a common maintenance failure point. The needed response is: Separate central Policy Administration Node responsibilities from appropriate Policy Service Nodes, and distribute RADIUS requests to healthy PSNs.
A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The actual fault is governed by a different mechanism: the PAN manages configuration while PSNs process live network-access authentication; co-locating them creates a common maintenance failure point. The needed response is: Separate central Policy Administration Node responsibilities from appropriate Policy Service Nodes, and distribute RADIUS requests to healthy PSNs.
