configuration as shown in the exhibit. However, the approved traffic is still dropped.
What are two reasons for this behavior? (Choose two.)

A.
The approved traffic results in 50,000 HTTP GET requests per minute.

B.
The approved traffic results in 25 HTTP GET requests within 10 seconds from a single host.

C.
The active IDP policy has not been defined in the security configuration.

D.
The IDP action is still in effect due to the timeout configuration.
