NSE 4 – FortiGate 6.0 — Question 87

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

Answer options

• A. All interfaces of the transparent mode FortiGate device must be on different IP subnets.
• B. Ethernet packets are forwarded based on destination MAC addresses, not IP addresses.
• C. The transparent FortiGate is visible to network hosts in an IP traceroute.
• D. It permits inline traffic inspection and firewalling without changing the IP scheme of the network.
• E. FortiGate acts as transparent bridge and forwards traffic at Layer 2.

Correct answer: B, D, E

Explanation

The correct answers are B, D, and E because transparent mode operates at Layer 2, forwarding packets based on MAC addresses, allowing for inline traffic inspection without necessitating changes to the IP scheme. Option A is incorrect as it is not a requirement for interfaces in transparent mode to be on different IP subnets, and option C is wrong since a transparent FortiGate is typically not visible in an IP traceroute.
