In FortiOS 7.6 Application Control, security logs are generated primarily for actions such as Block or Monitor, not for Allow actions.

What is happening in the exhibit

An Application Override is configured for ABC.Com

Type: Application

Action: Allow

The application control profile is applied to a firewall policy

Logging is enabled on the firewall policy

Traffic to ABC.Com is successfully allowed

However, no security logs appear for ABC.Com.

Why no logs are generated

In FortiOS 7.6:

Application Control logs are written to Security Logs when:

An application is Blocked

An application is Monitored

When an application action is set to Allow:

The traffic is permitted silently

No application control security log is generated

Even if policy logging is enabled

This is expected and documented behavior.

To generate logs for allowed applications, the action must be set to Monitor, not Allow.

Why the other options are incorrect

A. ABC.Com is hitting the category Excessive-BandwidthIncorrect. ABC.Com has a higher-priority explicit override (priority 1), so it is not evaluated against the Excessive-Bandwidth filter.

B. The ABC.Com Type is set as Application instead of FilterIncorrect. Application-type overrides are valid and commonly used; this does not suppress logging.

C. The ABC.Com must be configured as a web filter profileIncorrect. This traffic is being evaluated by Application Control, not Web Filter.

In FortiOS 7.6, when a FortiGate is operating in NAT mode, physical interfaces that participate in traffic forwarding (such as LAN and DMZ) must meet certain fundamental requirements.

Correct statements

D. Both interfaces must have IP addresses assigned.

Correct

In NAT mode, FortiGate operates as a Layer-3 device.

Every interface that forwards traffic must have an IP address.

Without an IP address:

The interface cannot participate in routing

Firewall policies cannot be applied correctly

This is a mandatory requirement.

C. Both interfaces must have directly connected routes on the routing table.

Correct

When an IP address is assigned to an interface, FortiGate automatically installs a connected route for that subnet in the routing table.

These connected routes are required so FortiGate:

Knows how to reach the locally attached networks

Can forward traffic between LAN and DMZ

While administrators do not manually create these routes, their presence is required for correct operation.

Why the other options are incorrect

A. Both interfaces must have DHCP enabled and roles assigned.

Incorrect

DHCP is optional; interfaces can use static IPs.

Interface roles (LAN, DMZ, WAN) are administrative/GUI aids, not functional requirements.

B. Both interfaces must have the interface role assigned.

Incorrect

Interface roles affect GUI grouping and some default behavior.

They are not required for NAT mode operation or traffic forwarding.

According to the FortiOS 7.6 Administrator Study Guide and official documentation, SD-WAN rules (services) determine the path selection for traffic matching specific criteria. Version 7.6 provides specific flexibility regarding how these strategies handle multiple member interfaces.

First, Manual with load balancing (Statement B) is a valid configuration. In the Manual strategy, the administrator orders interfaces by preference, but by enabling the Load balancing toggle, the FortiGate can distribute traffic across all members that are up.

Second, the Lowest Cost (SLA) strategy has been enhanced to support two modes. When the load balancing option is disabled, it acts as Lowest Cost (SLA) without load balancing (Statement A), selecting the single lowest-cost link that meets the SLA. Alternatively, by enabling the toggle, it functions as Lowest Cost (SLA) with load balancing (Statement D), where the FortiGate distributes traffic across all interfaces that satisfy the SLA target, regardless of their individual costs.

Statements C and E are incorrect because "Lowest Quality" is not a recognized SD-WAN strategy, and the Best Quality strategy is specifically a priority-based selection for a single "best" link, meaning the load balancing toggle is not available in the GUI when this mode is selected.
