Based on the system performance output, which two results are correct?

Refer to the exhibits.

Exhibit A shows system performance output.

Exhibit B shows a FortiGate configured with the default configuration of high memory usage thresholds.

Based on the system performance output, which two results are correct? (Choose two.)
A . FortiGate will start sending all files to FortiSandbox for inspection.
B . FortiGate has entered conserve mode.
C . Administrators cannot change the configuration.
D . Administrators can access FortiGate only through the console port.

Answer: B,C

Explanation:

What actions does FortiGate take to preserve memory while in conserve mode?

• FortiGate does not accept configuration changes, because they might increase memory usage.

• FortiGate does not run any quarantine action, including forwarding suspicious files to FortiSandbox.

• You can configure the fail-open setting under config ips global to control how the IPS engine behaves when the IPS socket buffer is full.

Based on the system performance output, it appears that FortiGate has entered conserve mode and administrators cannot change the configuration.

FortiGate has entered conserve mode: When FortiGate enters conserve mode, it reduces its operational capacity in order to conserve resources and improve performance. This may be necessary if the system is experiencing high levels of traffic or if there are issues with resource utilization.

Administrators cannot change the configuration: When the system is in conserve mode, administrators may not be able to change the configuration. This is because the system is prioritizing resource conservation over other activities, and making changes to the configuration may require additional resources that are not available.

It is important to note that FortiGate will not start sending all files to FortiSandbox for inspection, and administrators may still be able to access FortiGate through other means besides the console port. "If memory usage goes above the percentage of total RAM defined as the red threshold, FortiGate enters conserve mode."

"FortiGate does not accept configuration changes, because they might increase memory usage."
