The FEC configuration in the exhibit specifies that if the packet loss is greater than 10%, then the FEC mapping will be 8 base packets and 2 redundant packets. The download bandwidth of 500 Mbps is not greater than 950 Mbps, so the FEC mapping is not overridden by the bandwidth setting. Therefore, the FEC behavior will be 2 redundant packets for every 8 base packets.

Here is the explanation of the FEC mappings in the exhibit:

Packet loss greater than 10%: 8 base packets and 2 redundant packets.

Upload bandwidth greater than 950 Mbps: 9 base packets and 3 redundant packets.

The mappings are matched from top to bottom, so the first mapping that matches the conditions will be used. In this case, the first mapping matches because the packet loss is greater than 10%. Therefore, the FEC behavior will be 2 redundant packets for every 8 base packets.

The exhibit shows that the FortiEDR core has detected an exfiltration attack. The attack is attempting to copy files from the device to an external location. The FortiEDR core has blocked the attack, and the files have not been exfiltrated.

The exhibit also shows that the attack is using the Cobalt Strike beacon. Cobalt Strike is a penetration testing tool that can be used for both legitimate and malicious purposes. In this case, the Cobalt Strike beacon is being used to exfiltrate files from the device.

The other options are incorrect. Option A is incorrect because the attack has not been stopped. Option C is incorrect because the attack is not a ransomware attack. Option D is incorrect because the FortiEDR core has not stopped the attack.

When using inbound SSL inspection, FortiGate needs to present a certificate to the client that matches the requested domain name. If no matching certificate is found in the server-cert list, FortiGate will fall-back to the default Fortinet_CA_SSL certificate, which is self-signed and may trigger a warning on the client browser.
