NEW QUESTION # 97
Refer to the exhibit.
The port1 interface configuration on FortiGate and partial session information for ICMP traffic are shown.
Which two things happen to the session information if a routing change occurs that affects this session? (Choose two answers)
Answer: B,C
Explanation:
The correct answers are A and C.
The exhibit shows that preserve-session-route is enabled on port1:
config system interface
edit "port1"
set preserve-session-route enable
next
end
The study guide explains the effect of this setting exactly:
"enable: FortiGate marks existing session routing information as persistent, and applies only the modified routes to new sessions" It also states:
"The current route must still be present in the FIB. Otherwise, FortiGate flags the session as dirty and reevaluates it" And the same page further clarifies:
"If you enable this setting, sessions passing through that interface continue to pass without being affected by the routing changes. The routing changes apply only to new sessions. If the route is removed from the FIB, then FortiGate must flag the session as dirty, flush its gateway information, and reevaluate the session." This proves:
A is correct because with preserve-session-route enable, existing sessions are normally preserved and routing changes apply only to new sessions.
C is correct because the session remains unchanged unless the current route is removed from the FIB/routing table, in which case FortiGate dirties and reevaluates the session.
Why the other options are wrong:
B is wrong because when the active route is removed, FortiGate does not simply mark the session dirty and stop there. The study guide says it "flags the session as dirty and reevaluates it", which means route lookup happens again.
D is wrong because the session does change if the active route is removed. FortiGate flushes gateway information and reevaluates the session.
So the verified answers are: A, C.
NEW QUESTION # 98
Refer to the exhibit.
The sniffer log on two FortiGate devices are shown. Based on the information in the log, which two factors explain the output on FortiGate FGT-02? (Choose two answers)
Answer: A,D
Explanation:
The output on FGT-01 confirms that the device is actively encapsulating traffic and sending it as ESP packets (Protocol 50) out of port1 towards the IP address 97.86.16.52. The logs show outgoing packets, which confirms FGT-01 is attempting to initiate or maintain the tunnel and that NAT-Traversal is not being used (as it uses raw ESP).
The output on FGT-02, however, displays (no packets captured). This is significant because the sniffer command diagnose sniffer packet any 'esp' captures traffic at the network interface level (ingress), regardless of whether a matching VPN configuration exists on the receiving unit. The absence of packets proves that the ESP traffic generated by FGT-01 is physically not arriving at FGT-02's interface.
This behavior is explained by two primary factors:
* Option A (Blocking): An intermediate device, such as an ISP router or firewall, is dropping Protocol
50 traffic. Unlike UDP 500/4500, raw ESP is often blocked by default on many networks or legacy devices.
* Option C (Routing/Misconfiguration): If the administrator configured the wrong remote peer IP on FGT-01, the packets are being routed to a different destination entirely. Consequently, they never arrive at FGT-02 to be captured.
Option B is incorrect because even without a configured VPN tunnel, the sniffer would still display the incoming ESP packets if they were reaching the interface. Option D is incorrect because FGT-01 is sending ESP, making 'esp' the correct filter.
NEW QUESTION # 99
Refer to the exhibit.
Which Iwo statements about FortiGate behavior relating to this session are correct? (Choose two.)
Answer: B,D
Explanation:
Based on the Fortinet FCSS - Network Security 7.6 documents and standard exam content for these specific troubleshooting scenarios, here are the verified answers.
Questions no: 74
Verified Answer: A, C
Comprehensive and Detailed Explanation with all FCSS - Network Security 7.6 documents:
This question typically refers to a session table exhibit showing Local Traffic (traffic originating from or destined to the FortiGate itself, such as management traffic, DNS queries initiated by FortiGate, or dynamic routing updates). These sessions are identified by Policy ID 0 or the absence of a forwarded interface pair (e.
g., local flag).
C). FortiGate either initiated the session or the session terminates at FortiGate:
This is the definition of Local Traffic. Unlike Forward Traffic (which passes through the FortiGate from one interface to another), local traffic belongs to the FortiGate's control plane (e.g., an administrator logging in, or the FortiGate connecting to FortiGuard).
In the session table, this is characterized by policy_id=0 or the source/destination being the FortiGate's own IP.
A). FortiGate is performing a security profile inspection using the CPU:
Local traffic and traffic requiring complex handling (like the application notification app_ntf seen in similar exhibits) are processed by the CPU (Kernel) rather than being fully offloaded to the NPU (Network Processor) fast path.
The NPU cannot handle local host traffic (traffic destined to the FortiGate CPU). Therefore, the CPU must process these packets.
Why other options are incorrect:
B: Captive portal redirection involves specific authentication flags and HTTP redirection, usually seen as a forwarding decision, not a completed local session.
D: "Forwarded without inspection" describes an offloaded or fast-pathed session (NP6/NP7), which would not be local traffic and would show hardware offload flags (e.g., np6_0).
Reference:
FortiGate Security 7.6 Study Guide (Diagnostics): "Traffic originating from the FortiGate or destined to the FortiGate (Local-In/Local-Out) is always processed by the CPU and cannot be offloaded."
NEW QUESTION # 100
Refer to the exhibit, which shows a partial output of a real-time LDAP debug.
What two conclusions can you draw from the output? (Choose two.)
Answer: A,D
NEW QUESTION # 101
Refer to the exhibit, which shows the output of a BGP debug command.
What can you conclude about the router in this scenario?
Answer: C
Explanation:
The BGP debug output shows session information for peers, including state details. According to official Fortinet BGP documentation, if the session state with a peer does not show "Idle," "Active," or "Connect," but instead shows "Established," "Up," or related counters (e.g., messages sent/received or uptime), it indicates the session is operational. In this scenario, the peer 10.127.0.75 is the only one showing a positive indication of a live, established session. Other options like neighbor-range configuration, AS mismatch, or route-maps blocking prefixes are not supported by evidence provided in a simple BGP session state debug, nor does the output show errors relating to local or remote AS issues.
The correct interpretation comes from Fortinet's BGP troubleshooting guide, which outlines how to read session status and neighbor states in debug and summary outputs.
