In defining a user defined policy on Cascade Profiler that triggers when the aggregate connection rate from any internal host to all external hosts exceeds a certain threshold, one has entered "within internal" for host/group A and "outside internal" for host/group B. How should the statistics be tracked for host/group A and B?

  • A. host/group A "Track in aggregate" host/group B "track per host".
  • B. host/group A "track per host" host/group B "track in aggregate".
  • C. host/group A "track in aggregate" host/group B "track in aggregate".
  • D. host/group A "track per user" host/group B "track per user".
  • E. a user defined policy cannot support this scenario because it involves tracking traffic to external hosts.

Answer : D

If there is a Layer 7 fingerprint and a Layer 4 mapping for a particular application, which of the following is truE. (Select 5)

  • A. If the Layer 4 mapping override policy is not "Unknown/Unclassified", the Layer 4 mapping applies to flows not passing a Sensor or other application fingerprinting device as well as to flows not matching any defined Layer 7 fingerprint
  • B. If the Layer 4 mapping override policy is "Always", then the Layer 7 fingerprint will never be used for flows matching both criteria
  • C. If the Layer 4 mapping override policy is "Unclassified", the Layer 4 mapping only applies to flows not passing a Sensor or other application fingerprinting device
  • D. If the Layer 4 mapping override policy is "Unknown/Unclassified", the Layer 4 mapping applies to flows not passing a Sensor or other application fingerprinting device as well as to flows not matching any defined Layer 7 fingerprint
  • E. Care must be taken when defining reports and policies to reflect overlapping definitions and the Layer 4 override policy
  • F. The traffic Expression "app L7_fingerprint or app L4_mapping" will catch all traffic flows for the application data in a report
