Question 9

An organization is deploying FortiGate in Transparent mode instead of NAT mode. How does a Transparent mode FortiGate handle incoming packets at Layer 2?

Accepted Answer

It operates as a Layer 2 bridge, inspecting traffic without altering IP addresses or performing routing. In Transparent mode, the FortiGate operates as a bridge (Layer 2 device) without modifying IP addresses, inspecting traffic as it passes between interfaces on the same subnet.

Answer

It performs full NAT on all source and destination IP addresses for every packet

Answer

It terminates all Ethernet frames and encapsulates them into PPPoE tunnels

Answer

It acts as a dynamic routing peer running BGP and OSPF across all interfaces

Question 10

An enterprise is deploying FortiGate High Availability (HA) in active-active mode. How does active-active mode differ from active-passive mode regarding session handling?

Accepted Answer

Active-active distributes session processing across multiple cluster units, whereas active-passive processes all traffic on a single primary unit. In active-active mode, session load is distributed across multiple cluster members using session-pickup/load-balancing mechanisms, whereas active-passive runs all traffic through the primary unit until a failover occurs.

Answer

Active-active requires manual administrator failover, while active-passive is fully automated

Answer

Active-active disables all firewall security profiles to maximize raw throughput

Answer

Active-active eliminates the need for heartbeat cables between cluster units

Question 11

Which THREE components or protocols are involved in establishing and maintaining a FortiGate High Availability (HA) cluster using FGCP? (Choose three.)
