Refer to the exhibit.

Which Iwo statements about FortiGate behavior relating to this session are correct? (Choose two.)

FortiGate is performing a security profile inspection using the CPU.

FortiGate redirected the client to trio captive portal to authenticate so that a correct policy match could be

FortiGate either initiated the session or the session terminates at FortiGate.

FortiGate forwarded this session without any inspection.

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 83
Which statement about IKEv2 is true?

IKEv1 and IKEv2 use the same TCP port but run on different UDP ports.

IKEv1 and IKEv2 have enough of the header format in common that both versions can run over the same UDP port.

IKEv1 and IKEv2 share the concept of phase1 and phase2.

Both IKEv1 and IKEv2 share the feature of asymmetric authentication.

NEW QUESTION 84
Refer to the exhibit, which shows one way communication of the downstream FortiGate with the upstream FortiGate within a Security Fabric.

What three actions must you take to ensure successful communication? (Choose three.)

You must authorize the downstream FortiGate on the root FortiGate.

FortiGate must not be in NAT mode.

Ensure TCP port 8013 is not blocked along the way.

You must enable Security Fabric/Fortitelemetry on the receiving interface of the upstream FortiGate.

What is the most likely cause of this issue?

A batter route to the 8.8.8.8/32 network exists in the routing table.

FGT-B is configured with a prefix list denying the 8.8.8.8/32 network to be injected into the routing table.

The administrator has misconfigured redistribution of routes on FGT-A.

FGT-B is configured with a distribution list denying the 8.8.8.8/32 network to be injected into the routing table.

OSPF interface network types match.

Authentication settings match.

OSPF router IDs are unique.

NEW QUESTION 96
What are two reasons you might see iprope_in check () check failed, drop when using the debug How?
(Choose two.)

The packet was dropped because it is not allowed by any firewall policy.

The packet was dropped because there is no route to the source.

The packet was dropped because the trusted host list is misconfigured

The packet was dropped because the requested service is not enabled on FortiGate

The debug flow message iprope_in_check() check failed, drop specifically indicates a failure in the Local-In Policy check. The “iprope” (IP ROouting Policy Enforcement) engine handles policy lookups. The _in_check suffix confirms that the decision is regarding traffic destined to the FortiGate itself (Local-In traffic), rather than traffic passing through it.
D). The packet was dropped because the requested service is not enabled on FortiGate:
This is the most common cause. When a packet arrives destined for the FortiGate’s interface IP (e.g., an HTTPS or SSH request), the kernel checks if that specific service is enabled in the interface settings (set allowaccess). If the service is not enabled (e.g., trying to Ping an interface where PING access is disabled), the iprope_in_check function fails and drops the packet immediately.
C). The packet was dropped because the trusted host list is misconfigured:
Even if the service (e.g., HTTPS) is enabled on the interface, the FortiGate checks the Administrator settings.
If Trusted Hosts are configured, the source IP of the incoming packet is compared against the allowed list. If the IP is not on the list, the Local-In policy check (iprope_in_check) fails, and the packet is dropped to secure the management plane.
Why other options are incorrect:
A: If traffic is dropped by a standard Firewall Policy (traffic passing through the device from one interface to another), the debug message will typically state denied by policy x or no matching policy. It would generally be a forward check (iprope_fwd_check or similar), not an _in_check.
B: If there is no route to the source, the error is a Reverse Path Forwarding (RPF) failure. The debug flow logs this explicitly 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. This occurs when traffic destined to the FortiGate is not allowed by the allowaccess configuration or is blocked by Trusted Host settings.”

NEW QUESTION 97
Which Iwo actions does FortiGate take after an administrator enables the auxiliary session selling? (Choose two.)

FortiGate only offloads auxiliary sessions.

FortiGate accelerates all ECMP traffic to the NP6 processor

FortiGates creates a now auxiliary session for each packet it receives.

FortiGate creates two sessions in case of a routing change.

NEW QUESTION 98

diagnose sniffer packet any ‘port 4500’

NEW QUESTION 99
Refer to the exhibit, which contains partial output from an IKE real-time debug.
