Fortinet Certification NSE7_NST-7.2 Passing Score

Next-hop IP address:

For a static route to be added to the routing table, the next-hop IP address must be reachable. If it is not reachable, the route cannot be considered valid and will not be added.

Interface status:

If the interface specified in the static route configuration is down, the route will not be added to the routing table. The interface must be up and operational for the route to be valid.

Priority and Distance:

While priority and administrative distance affect route selection, they do not prevent a route from being added to the routing table. Instead, they influence which route is preferred when multiple routes to the same destination exist.

Diagnose NPU NP6 Port-list Disable Command:

Thediagnose npu np6 port-list disablecommand disables specific ports on the NP6 processor. This can help in cases where you need to analyze traffic and the hardware offloading is interfering.

Command:diagnose npu np6 port-list disable 5 17(as shown in Option A).

Diagnose NPU NP6 Fastpath Disable Command:

Disabling the fastpath feature on NP6 can also allow for better visibility into the traffic as it bypasses hardware acceleration, which might obscure traffic details.

Command:diagnose npu np6 fastpath disable 0(as shown in Option C).

Understanding OSPF Roles:

In OSPF (Open Shortest Path First), routers can have different roles: Designated Router (DR), Backup Designated Router (BDR), and DROther. These roles help manage and optimize the OSPF network traffic.

DR and BDR are elected to minimize the number of adjacencies and reduce the amount of routing information exchange.

DROther routers are neither DR nor BDR but can still participate in the OSPF network by maintaining adjacencies with DR and BDR.

Analyzing the Exhibit:

The exhibit shows the OSPF neighbor states for the local FortiGate.

Neighbor ID 0.0.0.1 is in the state Full/DR (Designated Router).

Neighbor ID 0.0.0.3 is in the state Full/DROther (DROther).

Neighbor ID 0.0.0.10 has no specific designation, implying it is neither DR nor BDR.

Conclusion:

Since the local FortiGate shows neighbors in Full/DR and Full/DROther states and itself does not have a state of DROther, it can be concluded that the local FortiGate is not a DROther.

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.
