When designing an ISE deployment across WAN links, what is the primary recommendation regarding MnT nodes?
MnT nodes write session and accounting data continuously to the PAN, so placing them on the same high-speed network avoids WAN latency and bandwidth saturation. This satisfies the deployment's performance constraint, since replication and logging traffic across slow WAN links degrades PAN responsiveness and reporting accuracy.
Why this answer
Cisco recommends keeping the MnT (Monitoring and Troubleshooting) node in the same high-speed network as the PAN (Policy Administration Node) because MnT stores and processes large volumes of logging and session data, and it frequently communicates with the PAN for policy and configuration synchronization. Placing MnT across a WAN link introduces latency and potential replication issues.
Exam trap
SISE often tests the placement of ISE personas — candidates may assume MnT can be distributed like PSNs, but the trap is forgetting that MnT must be co-located with PAN for performance and replication.
How to eliminate wrong answers
Option A is wrong because distributing MnT nodes across all WAN sites is not supported in a single ISE deployment; MnT is a centralized role, and multiple MnT nodes must be in the same LAN as the PAN for proper operation. Option B is wrong because ISE does not support deploying MnT in the cloud as a standalone role; ISE nodes must be on-premises or in a supported cloud environment with proper connectivity. Option C is wrong because disabling logging for remote sites would eliminate visibility and violate compliance requirements, and it does not address MnT placement.
