Area summarization aggregates inter-area routes at the area boundary. This can be correct in another enterprise firewall scenario, but it does not directly satisfy the requirement to diagnose a neighbor stuck before Full state.
OSPF advertises connected prefixes according to the interface and area configuration. This can be correct in another enterprise firewall scenario, but it does not directly satisfy the requirement to diagnose a neighbor stuck before Full state.
OSPF neighbors require compatible parameters and bidirectional IP connectivity. This can be correct in another enterprise firewall scenario, but it does not directly satisfy the requirement to diagnose a neighbor stuck before Full state.
The neighbor state and interface parameters identify where adjacency formation is failing. This directly addresses the stated requirement.

Question 21

While troubleshooting at Wide World Importers, the network operations engineer needs to form an OSPF adjacency between two FortiGate interfaces on the same segment. What is the best next step? Use normal enterprise Fortinet administration practice. The team must preserve existing certificate-trust relationships unless the requirement explicitly changes them.

Enable OSPF on the intended interface or network and place it in the correct area
Inspect OSPF neighbor state, hello parameters, MTU, authentication, network type, and packet flow on the interface
Match area, network type, authentication, timers, MTU expectations, and interface reachability, then verify neighbor state
Configure the interface as passive while keeping the connected network in the OSPF process
Configure the appropriate OSPF area-range or summarization function on the ABR

Correct answer: C

Question 22

Relecloud is standardizing a FortiOS 7.6 enterprise deployment. Which approach should it use to advertise an internal subnet into OSPF from the correct FortiGate interface? Assume the platform versions are compatible with the feature. The change will be reviewed later using the configuration and event audit trail.

Configure the appropriate OSPF area-range or summarization function on the ABR
Enable OSPF on the intended interface or network and place it in the correct area

Question 23

A change ticket for Adventure Works states that administrators must prevent a user-facing interface from attempting to form OSPF neighbors while still advertising its subnet. Which choice is correct? No unrelated control should be weakened. The chosen approach must continue to work as additional branch sites are added.

Configure the interface as passive while keeping the connected network in the OSPF process
Configure the appropriate OSPF area-range or summarization function on the ABR
Inspect OSPF neighbor state, hello parameters, MTU, authentication, network type, and packet flow on the interface

Question 24

The security team at Fourth Coffee wants to summarize routes at an area boundary to reduce routing-table entries. Which configuration or operational action most directly satisfies that goal? The team will validate the result immediately after the change. A second engineer will verify the result using independent operational evidence.
