Fortinet Updated NSE7_FSN_AR-7.6 Exam Questions and Answers by casey

The correct answers are A and B .

For UDP , the study guide states this directly: “For UDP, the session state can have only two values: 00 when traffic is only one way, and 01 when traffic is two ways. For ICMP, the protocol state is always 00.”

That makes B correct and D incorrect.

For TCP , the study guide explains that the protocol state is a two-digit number, where the first digit is the server-side state and the second digit is the client-side state . It also states that the first digit is 0 when the session is not subject to any inspection , and the TCP state table shows that value 1 = ESTABLISHED

So, for a normal non-proxied/non-inspected TCP session, proto_state=01 means the TCP session is in the ESTABLISHED state. An established TCP session means the three-way handshake has completed, which requires traffic in both directions. That is why A is correct.

The study guide also says: “proto_state=11 means that the TCP three-way handshake for both server-side and client-side is completed (ESTABLISHED).”

This confirms that TCP state value 1 represents an established state.

Why C is not selected: the study guide defines value 5 as TIME_WAIT and says: “When a session is closed by both the sender and receiver, FortiGate keeps that session in the session table for a few seconds… This is the state value 5.”

So proto_state=05 represents a closing/closed TCP session in TIME_WAIT , not the normal bidirectional state the question is testing.

Therefore, the verified answers are A and B .

The correct answers are B and C . The session table output clearly shows policy_id=1 , which means the traffic matched firewall Policy ID 1 . That directly validates option B . The output also shows NPU-related offload indicators, including npu_state=... ips_offload and npu info: ... offload=8/8, ips_offload=1/1 . These fields indicate that the session has been offloaded to hardware, so option C is correct. The study guide explains that FortiGate can offload sessions to network processors after session establishment, allowing subsequent packets to bypass normal CPU/kernel processing for improved performance. It also states that offloaded sessions are handled by the network processor rather than the CPU path.

Option A is too specific and is not proven by the exhibit. The output shows NPU offload, but it does not explicitly identify the hardware as NP7. Do not assume NP7 unless the platform or output confirms it. Option D is wrong because the VLAN-related fields show vlan=0x0000/0x0000 and vtag_in=0x0000/0x0000, which means the traffic is not VLAN-tagged.

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.
