The exhibit shows a security policy configuration with a threshold of 1000 policy violations by a source network identifier and a threshold of 10 policy violations to an application within a specified period. If either of these thresholds are exceeded, an alarm will be generated. Therefore, the correct answer is A and D. The other options are incorrect because:
B) The ratio of policy violation traffic compared to accepted traffic is not a criterion for triggering an alarm.
The security policy configuration does not specify any ratio or percentage of policy violation traffic that would cause an alarm.
C) The number of policy violation by a destination TCP port is also not a criterion for triggering an alarm.
The security policy configuration does not specify any threshold or duration for policy violation by a destination TCP port.
