The administrator cannot see traffic in the sniffer because it is being offloaded to the NPU (NP6). To view the traffic, offloading must be disabled so packets pass through the CPU.
B). config firewall policy ... set auto-asic-offload disable: This is the recommended method to troubleshoot specific traffic. By disabling ASIC offloading in the relevant firewall policies (Policies 5 and 17 in the exhibit), traffic is forced to the CPU and becomes visible to the sniffer.
C). diagnose npu np6 fastpath disable 1: This command temporarily disables the fastpath processing on the specific NP6 processor (ID 1) handling the ports. This forces all traffic handled by that NPU to the CPU, allowing the sniffer to capture it.
Incorrect Options: Option A uses invalid syntax (port-list disable is not a valid command). Option D (config system npu) is not the standard method for granular troubleshooting.

The correct answer is B.
The study guide states that for TCP, the protocol state is a two-digit number. The first digit is the server-side state and is 0 when the session is not subject to inspection. The second digit is the client-side state. It also shows that value 1 = ESTABLISHED So, for a normal TCP session with no inspection, proto_state=01 means:
first digit 0 = no inspection
second digit 1 = ESTABLISHED
That makes B correct.
Why the other options are wrong:
A is wrong because for UDP, the study guide says 00 = one-way traffic and 01 = two-way traffic C is wrong because 10 does not represent the normal established TCP session described in the study guide.
The established example shown is based on state value 1, and the guide explicitly highlights proto_state=11 when both server-side and client-side TCP handshakes are completed D is wrong because for ICMP, the study guide says "the protocol state is always 00"

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.

The Enterprise Firewall 7.6 Administrator Study Guide explains: "The root FortiGate acts as the identity provider (IdP) and you configure the other devices as service providers (SP)." Therefore, the root FortiGate authenticates the credentials for the AdminSSO administrator, while the downstream FortiGate operates as the SAML service provider.
After successful authentication, the root FortiGate returns a SAML assertion to the downstream FortiGate.
The downstream device then grants access according to its configured SAML administrator profile. The exhibit shows that its Default admin profile is super_admin_readonly. Consequently, the user is logged in to the downstream FortiGate with read-only super-administrator privileges.
The browser can be redirected temporarily to the root FortiGate for identity-provider authentication, but that is not the final access outcome, so option A is incomplete. AdminSSO is the administrator account name, not an access profile, and the user is not left on the root FortiGate, eliminating option C. Because the credentials are successfully authenticated, option D is also incorrect.

The correct answer is A .
The debug output is for an HTTPS request and shows a hostname value. The study guide explains that with SSL certificate inspection, FortiGate extracts the FQDN from either:
* "TLS extension server name indication (SNI)"
* "SSL certificate common name (CN)"
So the hostname shown in the real-time web-filter debug can be derived from the SNI in the client request or, if needed, from the CN in the server certificate. That makes A correct.
Why the other options are wrong:
* B is wrong because the study-guide example for web-filter real-time debug explicitly says: "This slide shows an example of real-time debug output when the URL to categorize isn ' t in the FortiGuard cache." In these debugs, cat=255 appears before the final lookup result, so this does not indicate a local- cache hit.
* C is wrong because ftgd-allow is the action , not the profile name. The debug line shows the action as action=9 (ftgd-allow) while the profile shown is profile= ' default ' . FortiOS web-filter logs also use the profile field separately from the action field
* D is wrong because the final category shown is url_cat=52 , not 255. The study guide's example shows the same pattern: an initial cat=255 in the request line, followed by the resolved result cat=52 url_cat=52 So the verified answer is: A .
