FCSS_EFW_AD-7.4 Dumps with Practice Exam Questions Answers

Applying anaggressive IPS profilewithout prior testing candisrupt legitimate applicationsby incorrectly identifying normal traffic as malicious. To prevent disruptions while still monitoring for threats:

●Enable IPS in "Monitor Mode" first:

● This allows FortiGate tolog and analyzepotential threatswithout actively blockingtraffic.

● Administrators can review logs and fine-tune IPS signatures to minimize false positives before switching to blocking mode.

●Verify and adjust signature patterns:

● Some signatures might trigger unnecessary blocks for legitimate application traffic.

● By analyzing logs, administrators candisable or modifyspecific rules causing false positives.

FortiGate_A and FortiGate_B are in thesame autonomous system (AS), andFortiGate_Adoesnot currently have route 172.16.1.248/30in its routing table. However, FortiGate_B has this routeas a connected route.

To dynamically advertiseonly172.16.1.248/30 fromFortiGate_B to FortiGate_A, the administrator must configure aBGP route map outonFortiGate_Bthat specifically permitsonlythis prefix.

A BGP route map out on FortiGate_Bcontrols which routes FortiGate_B advertises to FortiGate_A. If no filtering is applied, FortiGate_B might advertiseall BGP-learned and connected routes, which is not what the administrator wants. The route map should include aprefix-listthat explicitlyallows only172.16.1.248/30 and denies everything else.

Zero phase selectors inIPsec Phase 2mean thatno specific traffic selectors (subnets) are defined, allowingany traffic to be encryptedthrough the VPN tunnel. This can causeunintended traffic forwarding issuesand disrupt network operations.

To prevent this from happening during future migrations:

●Using routing protocolsensures thatonly specific subnets are advertised over the tunnel. Dynamic routing (such as OSPF or BGP) helps define which networks should use the tunnel, preventing unintended traffic from being encrypted.

●Clearly defining phase 2 selectorsavoids the problem of encrypting all traffic byexplicitly stating the allowed source and destination subnets. This prevents the tunnel from affecting unrelated network traffic.

TheFortinet FGSP (FortiGate Session Life Support Protocol) clusterallows session synchronization betweentwo FortiGate devicesto provide seamless failover. However,ICMP (ping) is a connectionless protocol, and by default, FortiGate does not synchronize connectionless sessions unless explicitly enabled.

In the exhibit:

● The commandget system session list | grep icmponFortiGate_Breturnsno output, meaning that ICMP sessions arenot being synchronizedfrom FortiGate_A.

● Ifsession-pickup-connectionlessis disabled,FortiGate_B will not receive ICMP sessions, causingpacket lossduring failover.

The diagram shows amulti-area OSPF networkwhere:

●FortiGate Ais inOSPF Area 0 (Backbone area).

●FortiGate Bis inOSPF Area 0.0.0.1and is connected to anRIP network.

To ensure thatOSPF Area 0 (0.0.0.0) learns routes from the external RIP network, FortiGate B mustredistribute RIP routes into OSPF.

Steps to achieve this:

1.Enable route redistribution on FortiGate Bto inject RIP-learned routes into OSPF.

2. This allows OSPFArea 0.0.0.1to forward RIP routes toOSPF Area 0 (0.0.0.0), making the external network visible.
