NSE7_NST-7.2 Exam Dumps : Fortinet NSE 7 - Network Security 7.2 Support Engineer

Examine the OSPF debug output:

The OSPF Hello packet debug output shows the Router ID as0.0.0.112.

It shows that the OSPF packet is being sent from0.0.0.112viaport2:192.168.37.114.

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 as0.0.0.0, indicating that the two devices attempting adjacency are in area0.0.0.0.

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.

The session table entry provided shows detailed information about a specific network session passing through the FortiGate device. From the session details, we can see that the session has various attributes such as state, protocol, policy, and inspection details.

The session state (proto_state=11) indicates that the session is being actively processed and inspected.

Thenpd_state=00000000suggests that the session is being handled by the CPU rather than offloaded to a Network Processor (NP).

The session is marked for security profile inspection, evident from the detailed byte/packet counts and other session parameters.

From these indicators, it's clear that FortiGate is using its CPU to perform security profile inspection on this session rather than simply forwarding the traffic without inspection or relying solely on IPS inspection.

Session Table Overview:

The session table in FortiOS tracks all active and pending sessions. It includes details like the type of session (TCP, UDP, etc.), status, and statistics.

Interpreting the Exhibit:

The exhibit from thediagnose sys session statcommand shows detailed session statistics.

The specific value indicating "166 TCP sessions waiting to complete the three-way handshake" reflects the number of sessions that have initiatedbut not yet completed the TCP three-way handshake process (SYN, SYN-ACK, ACK).
