If no firewall policy is specified between two FortiGate interfaces and zones are not used, which of the following statements describes the action taken on traffic flowing between these interfaces?

The FortiGate operates on an implicit deny principle; any traffic that does not explicitly match an allowed firewall policy between interfaces or zones is automatically blocked by default.

Traffic is not passed by default; an explicit firewall policy is always required to allow traffic to flow between interfaces.

Traffic is not passed by default, and logging of implicitly denied traffic is not enabled without specific configuration; the fundamental action is to block.

While the traffic is blocked, logging of implicitly denied traffic is not enabled by default and requires separate configuration; the primary action is the block.
