Fortinet FCSS - Network Security 7.6 Support Engineer 認定 FCSS_NST_SE-7.6 試験問題 (Q21-Q26):質問 # 21
Exhibit.

Refer to the exhibit, which contains partial output from an IKE real-time debug.
Which two statements about this debug output are correct? (Choose two.)
  • A. Perfect Forward Secrecy (PFS) is enabled in the configuration.
  • B. The local gateway IP address is 10.0.0.1.
  • C. The initiator provided remote as its IPsec peer ID.
  • D. It shows a phase 2 negotiation.
正解：C、D
解説：
From the exhibit, you can observe that the debug output captures an IKEv1 negotiation in aggressive mode.
Let's break down the supporting details in line with official Fortinet IPsec VPN troubleshooting resources and debug guides:
For Option B:
The very first line of the debug output shows:
comes 10.0.0.2:500->10.0.0.1:500, ifindex=7.
This indicates the traffic direction-from the remote IP (10.0.0.2) with port 500 to the local IP (10.0.0.1) with port 500. According to Fortinet's documentation, the right side of the arrow always represents the local FortiGate gateway. Thus, 10.0.0.1 is the local gateway IP address.
For Option D:
You see the statement:
negotiation result "remote"
and
received peer identifier FQDNCE88525E7DE7F00D6C2D3C00000000
Official debug documentation describes that the "peer identifier" or peer ID sent by the initiator is displayed here. In the context of IKE/IPsec negotiation, this value is used as the IPsec peer ID for authentication and identification purposes. The initiator is providing "remote" as the peer ID for its connection.
Why Not A or C:
Perfect Forward Secrecy (PFS): The debug does not show any DH group negotiation in phase 2 (no reference to group2, group5, etc., for phase 2), so you cannot deduce the presence of PFS solely from this output.
Phase 2 negotiation: The log focuses on IKE (phase 1) negotiation and establishment; there's no reference to ESP protocol, Quick Mode, or other identifiers that would show phase 2 SA negotiation and establishment.
This interpretation aligns with the explanation in the FortiOS 7.6.4 Administration Guide's VPN section and the official debug command output samples published in Fortinet's documentation. It demonstrates how to distinguish between local and remote addresses and how to identify the use of peer IDs.

質問 # 22
Refer to the exhibit.

The modified output of live routing kemel is shown
Which two statements about the output are (rue? (Choose two.)
  • A. The default static route through 10.200.1 254 is in the forwarding information* base.
  • B. FortiGate is performing ECMP using both default static routes.
  • C. The BGP route to 10.0.4.0/24 is not in the forwarding information base.
  • D. The local FortiGate is receiving only one LSA from one OSPF neighbor.
正解：A、C
解説：
We must analyze the flags (*, >, S, O, B) and Administrative Distances (AD) shown in the get router info routing-table database exhibit to determine the correct statements.
Analysis for Option A (The BGP route to 10.0.4.0/24 is not in the forwarding information base):
True. Look at the entry for 10.0.4.0/24.
There is an OSPF route: O *> 10.0.4.0/24 [110/2]. The * indicates it is in the FIB, and > indicates it is the selected route.
There is a BGP route: B 10.0.4.0/24 [200/10]. This line lacks the * flag.
Reason: The OSPF route has an Administrative Distance of 110. The BGP route (iBGP) has an AD of 200.
Since 110 is lower than 200, OSPF wins, and the BGP route is not installed in the Forwarding Information Base (FIB).
Analysis for Option B (The default static route through 10.200.1.254 is in the forwarding information base):
True. Look at the 0.0.0.0/0 entries.
The first entry is S *> 0.0.0.0/0 [10/0] via 10.200.1.254.
The * flag confirms this specific route is installed in the FIB.
The second static route (via 10.200.2.254) has a higher distance ([20/0]) and no * flag, so it is inactive.
Why C is False: ECMP (Equal Cost Multi-Path) requires routes to have the same cost/priority. Here, one static route has AD 10 and the other has AD 20. They are not equal, so ECMP is not performed.
Why D is False: The routing table database shows active routes, not the raw Link State Advertisement (LSA) database. You cannot determine the number of LSAs received solely from this output.
Reference:
FortiGate Security 7.6 Study Guide (Routing): "The routing table database displays all known routes... The * indicates the route is in the FIB... Lower Administrative Distance is preferred."

質問 # 23
Refer to the exhibit.

Which route will traffic take to get to the 100.65.0.0/24 network considering the routes are all configured with the same distance?
  • A. The OS PF route
  • B. The static route
  • C. The BGP route
  • D. The policy route
正解：D
解説：
To determine the path the traffic will take, we must look at the FortiGate Route Lookup Precedence (Packet Processing Flow) and the specific configurations shown in the exhibit Analyze the Routing Precedence:
In FortiOS, when a packet arrives (and is not part of an existing session), the FortiGate performs route lookups in a specific order:
Policy Routes: Configured under config router policy (or diagnose firewall proute list). These are checked first. If a packet matches the criteria (Source, Destination, Protocol, Incoming Interface), the Policy Route is used immediately, bypassing the standard routing table.
FIB (Forwarding Information Base): If no Policy Route matches, the device looks at the standard routing table (Static, Connected, Dynamic).
Analyze the Exhibit:
Policy Route Section: The output of diagnose firewall proute list shows an active policy route (id=1).
Destination: 100.65.0.0/255.255.255.0 (Matches the network in the question).
Action: It directs traffic to gateway 10.0.4.253 via oif=6(port4).
Routing Table Section: The output of get router info routing-table database shows multiple routes for
100.65.0.0/24 (Static, OSPF, BGP) all with distance 10. The Static route (S) is currently selected (*>) in the FIB.
Conclusion:
Because Policy Routes take precedence over the standard routing table (FIB), the FortiGate will forward the traffic using the instructions in Policy Route ID 1. It will not use the Static, BGP, or OSPF routes visible in the routing table for any traffic that matches the policy route's criteria (ingress port 3).
Reference:
FortiGate Security 7.6 Study Guide (Routing): "Policy routes take precedence over entries in the routing table.
If a packet matches a policy route, the FortiGate routes the packet according to the specified interface and gateway."

質問 # 24
Refer to the exhibit.

The administrator did not override the FortiGuard FODN or IP address in the FortiGate configuration Which IP address did FortiGate get when resolving the servicem,fortiguard.net name?
  • A. 208.91.112.194
  • B. 64.26.151.37
  • C. 209.22.147.36
  • D. 96.45.33.65
正解：C
解説：
Based on the Fortinet FCSS - Network Security 7.6 documents and the analysis of the provided exhibits, here are the verified answers.
Questions no: 93
Verified Answer: B
Comprehensive and Detailed Explanation with all FCSS - Network Security 7.6 documents:
To determine which IP address was resolved via DNS, we must interpret the Flags column in the diagnose debug rating output provided in the exhibit:
Analyze the Flags:
Flag I (Initial): This flag indicates the IP address that was returned by the DNS query when resolving the FortiGuard FQDN (e.g., service.fortiguard.net). It acts as the "seed" or initial contact point.
Flag D (Discovered): This flag indicates servers that were not resolved via DNS but were learned dynamically from the FortiGuard network during protocol exchanges (server lists sent by the initial server).
Flag F (Failed): Indicates a server that the FortiGate tried to contact but failed.
Examine the Exhibit:
The IP address 209.22.147.36 has the flag I next to it.
The IP 208.91.112.194 has the flag D.
The IP 121.111.236.179 has the flag F.
Conclusion:
Since the question asks specifically for the IP obtained when resolving the name, we look for the "Initial" (I) flag. Therefore, 209.22.147.36 is the correct answer.
Reference:
FortiGate Security 7.6 Study Guide (Security Fabric & FortiGuard): "In diagnose debug rating, the 'I' flag stands for Initial, which is the IP address resolved by DNS. The 'D' flag stands for Discovered." Questions no: 94 Verified Answer: C, D Comprehensive and Detailed Explanation with all FCSS - Network Security 7.6 documents:
The error message iprope_in_check() check failed, drop in a debug flow indicates a failure in the Local-In Policy check. This function determines whether traffic destined to the FortiGate itself (management traffic or local services) is allowed.
C). The packet was dropped because the trusted host list is misconfigured:
Reason: If an administrator has configured Trusted Hosts (limiting administrative access to specific source IPs), and a packet arrives from an unauthorized IP, the iprope_in_check function will reject it immediately to protect the device.
D). The packet was dropped because the requested service is not enabled on FortiGate:
Reason: The most common cause for this error is that the destination interface does not have the specific service (e.g., SSH, HTTPS, PING) enabled in its set allowaccess configuration. If the service is not listening
/allowed on that port, the input check fails and drops the packet.
Why other options are incorrect:
A: If traffic is dropped by a standard firewall policy (traffic passing through the FortiGate), the debug message is typically denied by policy x or no matching policy, not an iprope (Input Property/Policy Enforcement) failure.
B: A routing issue where the source is unreachable results in a Reverse Path Forwarding (RPF) failure, typically logged as reverse path check fail, drop.
Reference:
FortiGate Troubleshooting Guide (Debug Flow): "The message iprope_in_check() check failed indicates the packet was denied by the Local-In policy, often due to missing allowaccess settings or Trusted Host restrictions."
