Fortinet NSE7_EFW-7.2 Dumps Questions Answers

The output of the BGP (Border Gateway Protocol) summary shows details about the BGP neighbors of a router, their Autonomous System (AS) numbers, the state of the BGP session, and other metrics like messages received and sent.

From the BGP summary provided:

A.External BGP (EBGP) exchanges routing information.This conclusion can be inferred because the AS numbers for the neighbors are different from the local AS number (65117), which suggests that these are external connections.

B.The BGP session with peer 10.127.0.75 is established.This is indicated by the state/prefix received column showing a numeric value (1), which typically means that the session is established and a number of prefixes has been received.

C.The router 100.64.3.1 has the parameter bfd set to enable.This cannot be concluded directly from the summary without additional context or commands specifically showing BFD (Bidirectional Forwarding Detection) configuration.

D.The neighbors displayed are linked to a local router with the neighbor-range set to a value of 4.The neighbor-range concept does not apply here; the value 4 in the 'V' column stands for the BGP version number, which is typically 4.

 Fail-open is a feature that allows traffic to pass through the IPS sensor without inspection when the sensor fails or is overloaded. If fail-open is set to disable, traffic will be dropped in such scenarios1. References: = IPS | FortiGate / FortiOS 7.2.3 - Fortinet Documentation

When IPS (Intrusion Prevention System) is configured, iffail-openis set to disable, it means that if the IPS engine fails, traffic will not be allowed to pass through, which can result in traffic being dropped (D). This is in contrast to a fail-open setting, which would allow traffic to bypass the IPS engine if it is not operational.

BFD (Bidirectional Forwarding Detection) is a protocol that can quickly detect failures in the forwarding path between two adjacent devices. You can disable BFD at the protocol level by using the “set bfd disable” command under the OSPF or BGP configuration. BFD works for both OSPF and BGP protocols, as well as static routes and SD-WAN rules. References := BFD | FortiGate / FortiOS 7.2.0 - Fortinet Document Library, section “BFD”.
