Which statement is false?

Refer to the exhibit, which shows the omitted output of a real-time OSPF debug

Which statement is false?
A . A password has been configured on the local OSPF router but is not shown in the output
B . The Hello packet is being sent from an OSPF router with ID 0.0.0.112.
C . The two FortiGate devices attempting adjacency are in area 0.0.0.0.
D . One FortiGate device is configured to require authentication, while the other is not

Answer: A

Explanation:

Examine the OSPF debug output:

The OSPF Hello packet debug output shows the Router ID as 0.0.0.112.

It shows that the OSPF packet is being sent from 0.0.0.112 via port2:192.168.37.114.

The OSPF Hello packet contains information such as the network mask (255.255.255.0), hello interval (10), router priority (1), dead interval (40), and designated router (192.168.37.114) and backup designated router (192.168.37.115).

Check the area configuration:

The area ID is shown as 0.0.0.0, indicating that the two devices attempting adjacency are in area 0.0.0.0.

Authentication mismatch:

The debug output indicates an "Authentication type mismatch". This means one device is configured to require authentication while the other is not.

Password configuration:

The statement claiming that "A password has been configured on the local OSPF router but is not shown in the output" is false because the output indicates an authentication mismatch, not the presence or absence of a password. The other statements are true based on the provided debug output.
