Question 12: Which internal Cisco ISE component reduces demand on JVM memory by limiting the number
of devices the profiler handles?
A. maxEndPointsInLocalDb
B. eventHandlerQueueSize
C. forwarderQueueSize
D. NetworkDeviceEventHandler
Correct Answer: C
Explanation
To ensure that the profiler does not increase the JVM memory utilization and prevent JVM to go out
of memory and restart, limits are applied to the following internal components of the profiler:
*Endpoint Cache-Internal cache is limited in size that has to be purged periodically (based on least
recently used strategy) when the size exceeds the limit.
*Forwarder-The main ingress queue of endpoint information collected by the profiler.
*Event Handler-An internal queue that disconnects a fast component, which feeds data to a slower
processing component (typically related to a database query).
Cisco ISE Profiler Queue Size Limits
*forwarderQueueSize = 5000 (endpoint collection events)
*eventHandlerQueueSize = 10000 (events)
