FCP_FGT_AD-7.4 - FCP - FortiGate 7.4 Administrator

Based on the system performance output provided, the memory usage on the FortiGate device is at 90%, which is above the green threshold (82%) but below the red threshold (88%). Given this high memory usage, the FortiGate device will enter "conserve mode" to prevent further resource exhaustion. In conserve mode:

B. FortiGate has entered conserve mode: When the memory usage reaches or exceeds certain thresholds (in this case, the green and red thresholds), the FortiGate enters conserve mode to protect itself from running out of memory entirely. This mode limits some functionalities to reduce memory usage and avoid a potential system crash.

D. Administrators can access FortiGate only through the console port: During conserve mode, administrative access might be restricted, and administrators may only be able to connect to the device via the console port. This restriction is in place to ensure that the FortiGate can be managed directly, even under low resource conditions.

The other options are not correct:

A. FortiGate will start sending all files to FortiSandbox for inspection: This is unrelated to memory usage and conserve mode.

C. Administrators cannot change the configuration: While access may be limited, configuration changes can still be made via the console port.

When the HA override setting is disabled, FortiGate uses the primary election process based on the following criteria:

Connected monitored ports: The unit with the most monitored ports up is preferred.

Priority: The unit with the highest priority is preferred.

System uptime: The unit with the longest uptime is preferred.

FortiGate serial number: Used as the final criterion to break any remaining ties.

The IPS sensor configuration shows that:

The Microsoft.Windows.iSCSI.Target.DoS signature is set to "Monitor" with packet logging enabled, meaning that while traffic matching this signature will be allowed, it will also be logged for further analysis.

The generic Windows filter is set to "Block," meaning that all other attacks matching this filter will be blocked. However, the sensor will not reset connections or log packets unless specified.

Therefore, the sensor will allow attackers matching the specific DoS signature while blocking other attacks against Windows.
