Question

A static route is configured for a FortiGate unit from the CLI using the following commands:

config router static edit 1 set device "wan1" set distance 20 set gateway 192.168.100.1 next end Which of the following conditions is NOT required for this static default route to be displayed in the FortiGate unit's routing table?

Options

  • AThe Administrative Status of the wan1 interface is displayed as Up.
  • BThe Link Status of the wan1 interface is displayed as Up.
  • CAll other default routes should have an equal or higher distance.
  • DYou must disable DHCP client on that interface.

Why each option

For a static route to be active, the egress interface must be up both administratively and physically, and its administrative distance must be favorable compared to other routes for the same destination; disabling the DHCP client on the interface is not a requirement for a static route's activation.

AThe Administrative Status of the wan1 interface is displayed as Up.

The wan1 interface must be administratively Up for any traffic to flow through it and for routes using it as an egress interface to be active in the routing table.

BThe Link Status of the wan1 interface is displayed as Up.

The physical Link Status of the wan1 interface must be Up to ensure connectivity to the specified gateway and for the static route to be considered valid and active.

CAll other default routes should have an equal or higher distance.

A static route with a specific administrative distance will only be preferred and installed in the routing table if there are no other routes to the same destination with a lower (better) administrative distance. This is crucial for default routes.

DYou must disable DHCP client on that interface.Correct

Disabling the DHCP client on the wan1 interface is not a prerequisite for a static route to become active. While a DHCP client might install its own default route, the configured static route will still be considered based on its administrative distance and interface status.
