Q8. - (Topic 11) 

Examine the exhibit; then answer the question below. 

The Vancouver FortiGate initially had the following information in its routing table: S 172.20.0.0/16 [10/0] via 172.21.1.2, port2 

C 172.21.0.0/16 is directly connected, port2 C 172.11.11.0/24 is directly connected, port1 Afterwards, the following static route was added: config router static edit 6 set dst 172.20.1.0 255.255.255.0 set pririoty 0 set device port1 set gateway 172.11.12.1 next end Since this change, the new static route is NOT showing up in the routing table. Given the 

information provided, which of the following describes the cause of this problem? 

A. The subnet 172.20.1.0/24 is overlapped with the subnet of one static route that is already in the routing table (172.20.0.0/16), so, we need to enable allow-subnet-overlap first. 

B. The 'gateway' IP address is NOT in the same subnet as the IP address of port1. 

C. The priority is 0, which means that the route will remain inactive. 

D. The static route configuration is missing the distance setting. 

Answer:

Q9. - (Topic 13) 

Which statements correctly describe transparent mode operation? (Choose three.)

C. The transparent FortiGate is clearly visible to network hosts in an IP trace route. 

D. Permits inline traffic inspection and firewalling without changing the IP scheme of the network. 

E. All interfaces of the transparent mode FortiGate device must be on different IP subnets. 

Answer: A,B,D 

Q10. - (Topic 14)
