Which, three conditions are required for two FortiGate devices to form an OSPF adjacency? (Choose three.)

Correct Answer:ABE
✑ Option A is correct because the OSPF interface network types determine how the routers form adjacencies and exchange LSAs on a network segment. The network types must match for the routers to become neighbors1.
✑ Option B is correct because the OSPF router IDs are used to identify each router in the OSPF domain and to establish adjacencies. The router IDs must be unique for the routers to become neighbors2.
✑ Option E is correct because the authentication settings control how the routers authenticate each other before exchanging OSPF packets. The authentication settings must match for the routers to become neighbors3.
✑ Option C is incorrect because the OSPF interface priority settings are used to elect
the designated router (DR) and the backup designated router (BDR) on a broadcast or non-broadcast multi-access network. The priority settings do not have to be unique for the routers to become neighbors, but they affect the DR/BDR election process4.
✑ Option D is incorrect because the OSPF link costs are used to calculate the
shortest path to a destination network based on the bandwidth of the links. The link costs do not have to match for the routers to become neighbors, but they affect the routing decisions5. References: =

Exhibit.

Refer to the exhibit, which contains a partial VPN configuration. What can you conclude from this configuration1?

Correct Answer:C
The configuration line “set dpd on-idle” indicates that dead peer detection (DPD) is set to trigger only when the tunnel is idle, not actively disabled1. References: FortiGate IPSec VPN User Guide - Fortinet Document Library
From the given VPN configuration, dead peer detection (DPD) is set to 'on-idle', indicating that DPD is enabled and will be used to detect if the other end of the VPN tunnel is still alive when no traffic is detected. Hence, option C is incorrect. The configuration shows the tunnel set to type 'dynamic', which does not create separate virtual interfaces for each dial- up client (A), and it is not specified that dynamic routing will be used (B). Since this is a phase 1 configuration snippet, the routing table aspect (D) cannot be concluded from this alone.

Exhibit.

Refer to the exhibit, which contains an active-active toad balancing scenario.
During the traffic flow the primary FortiGate forwards the SYN packet to the secondary FortiGate.
What is the destination MAC address or addresses when packets are forwarded from the primary FortiGate to the secondary FortiGate?

Correct Answer:A
In an active-active load balancing scenario, when the primary FortiGate forwards the SYN packet to the secondary FortiGate, the destination MAC address would be the secondary's physical MAC on port1, as the packet is being sent over the network and the physical MAC is used for layer 2 transmissions.
