Which of the following statements best describe what a FortiGate does when packets match a black hole route?

When packets match a black hole route on a FortiGate, the device discards them immediately without attempting to forward them or sending any notification back to the source. This behavior is crucial for preventing traffic from reaching its destination and mitigating denial-of-service attacks or routing loops.

Policy-based routing applies specific rules to forward traffic based on criteria other than the destination IP, which is not the function of a black hole route.

Sending an ICMP error message back to the originator would provide information about the dropped packet, which is not the intended stealthy behavior of a black hole route.

Routing packets back to the originator would create a loop or redirect traffic, which is contrary to the purpose of dropping packets with a black hole route.
