• Question 52:

  An analyst is encountering a large number of false positive results. Legitimate internal network traffic contains valid flows and events which are making it difficult to identify true security incidents.

  What can the analyst do to reduce these false positive indicators?

  A. Create X-Force rules to detect false positive events.

  B. Create an anomaly rule to detect false positives and suppress the event.

  A. Delete the volume of events and flows received in the last hour.

  B. Adjust the license pool allocations to increase the EPS and FPM capacity for the appliance.

  C. Tune the system to reduce the volume of events and flows that enter the event pipeline.

  D. Adjust the resource pool allocations to increase the EPS and FPM capacity for the appliance.

  E. Tune the system to reduce the time window from 60 minutes to 30 minutes.

  Correct Answer: BC

  Explanation:

  User response

  Adjust the license pool allocations to increase the EPS and FPM capacity for the appliance.

• Question 54:

  What is the reason for this system notification?

  

  A. Deny ntpdate communication on port 423.

  B. Deny ntpdate communication on port 223.

  C. Deny ntpdate communication on port 323.
