NSE4 · Question #49

Identify the statement which correctly describes the output of the following command: diagnose ips anomaly list

The correct answer is B. List the real-time counters for the configured DoS policy. The diagnose ips anomaly list command on a FortiGate displays real-time counters and statistics for configured Intrusion Prevention System (IPS) anomaly policies, often related to Denial of Service (DoS) protection.

Identify the statement which correctly describes the output of the following command:

diagnose ips anomaly list

Why each option

The `diagnose ips anomaly list` command on a FortiGate displays real-time counters and statistics for configured Intrusion Prevention System (IPS) anomaly policies, often related to Denial of Service (DoS) protection.

ALists the configured DoS policy.

This command displays the *runtime status and counters* of DoS anomaly policies, not the detailed configuration settings themselves.

BList the real-time counters for the configured DoS policy.Correct

The `diagnose ips anomaly list` command is specifically used to show current statistics, thresholds, and hit counts for IPS anomaly detection policies configured on the FortiGate, providing real-time operational data.

CLists the errors captured when compiling the DoS policy.

The `diagnose ips anomaly list` command does not report on compilation errors for DoS policies; it focuses on active detection statistics.

DLists the IPS signature matches.

This command specifically pertains to IPS anomaly detections (e.g., DoS attacks based on traffic patterns), distinct from listing individual IPS signature matches.
