FCSS_NST_SE-7.6 Exam Dumps - Fortinet Certified Solution Specialist Questions and Answers

The correct answers are A and D .

The Network Security Support Engineer 7.6 Study Guide explains that automation stitches consist of a trigger and one or more actions , and that they can detect events such as high CPU and conserve mode across the Security Fabric

The FortiOS administration guide then gives the exact practical example for A :

“Automation stitches can be created to run a CLI script and send an email message when memory or CPU usage exceeds specified thresholds.”

It also shows examples where the email body contains the script output using:

%%results%%

That directly confirms A .

For D , the FortiOS administration guide states:

“The URI and HTTP body can use parameters from logs or previous action results.”

It also explains the execution model:

“The stitch Action execution can be set to either Sequential or Parallel. In sequential execution actions will execute one after another with a delay (if specified). … In parallel execution all actions will execute immediately when the stitch is triggered.”

A concrete example shows a second action using the output of the first action:

“This string for the body text includes the results from the preceding CLI script action.” with

Body=%%results%%...

That confirms D .

Why the other options are wrong:

B is wrong because automation stitches can be triggered by IPS events, but the documentation does not describe them as modifying packet headers or payloads. Instead, they perform actions such as email, CLI script, webhook, quarantine, and similar automated responses

C is wrong because delay is associated with sequential execution, not parallel execution. The guide explicitly says: “A delay can be added before an action if Sequential action execution is used.”

So the verified answers are: A, D .

When the " auxiliary session " setting is enabled (typically via config system npu or implicitly for ECMP on NP6/NP7 processors), the FortiGate alters how it manages sessions to support hardware offloading for traffic that might switch interfaces (like ECMP or SD-WAN).

B. FortiGate accelerates all ECMP traffic to the NP6 processor:

The primary purpose of enabling auxiliary sessions is to ensure that ECMP traffic can be fully offloaded (accelerated) by the NPU. Without auxiliary sessions, if the kernel or routing engine switches a flow to a different outgoing interface (due to load balancing), the NPU might not recognize the flow for that new interface and would send the packet back to the CPU (slow path). Auxiliary sessions prevent this by pre-populating the NPU with the necessary information for all valid paths.

D. FortiGate creates two sessions in case of a routing change:

Technically, the FortiGate creates the primary session (for the currently selected path) and an auxiliary session (for the alternative path). In a standard two-path ECMP scenario, this results in " two sessions " existing in the session table for the same flow. This ensures that if a routing change occurs (e.g., the flow shifts to the second path), the traffic continues to be processed by the NPU without interruption or re-evaluation by the CPU.

The correct answers are B and C .

The study guide has a section titled “Not Verified Status on the Collector Agent” and states:

“The collector agent cannot verify if the user is still logged in” and lists these common causes :

“A firewall is blocking traffic to port 139 and 445”

“The workstation remote registry service is not running”

The guide also explains the verification method:

“For WMI polling mode, the collector agent checks the WMI service. For all the other modes, the collector agent checks the HKEY_USERS hive through remote registry services.” If the workstation does not respond to these checks, the status can become not verified

An additional requirements slide in the same study guide confirms:

“TCP ports 139 and 445 must be open between the collector agent and all workstations”

“Remote registry service must be up and running on each workstation”

Why the other options are wrong:

A is wrong because the study guide mentions a workstation coming out of hibernate mode under a different problem: “No Internet After IP Address Change” , not as a common cause of Not Verified status

D is wrong because DNS resolution issues are also discussed under the IP address change scenario, where the collector agent uses DNS to resolve the workstation name after an IP change. That is separate from the Not Verified causes listed for this log message

So the verified answers are: B, C .

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 correct answers are C and D .

The study guide’s get vpn ipsec tunnel details example shows:

replay: enabled

inbound and outbound sections with separate SPIs

NPU acceleration: encryption(outbound) decryption(inbound) and it labels these as “Phase 2 SAs for each direction” and “Hardware acceleration”

This directly proves D. Anti-replay is enabled , because the output explicitly says replay: enabled

For the NPU status, the study guide explains the exact npu_flag meanings:

npu_flag=00 = both IPsec SAs loaded to the kernel

npu_flag=01 = outbound IPsec SA copied to NPU

npu_flag=02 = inbound IPsec SA copied to NPU

npu_flag=03 = both outbound and inbound IPsec SAs copied to NPU

Because the exhibit shows hardware acceleration in both directions — encryption(outbound) and decryption(inbound) — the matching npu_flag is 03 , not 02. That makes C correct and A incorrect.

Why B is wrong:

The same study guide output labels the tunnel as having Phase 2 SAs for each direction , so different inbound and outbound SPIs are normal for the two SAs. Also, the FortiOS administration guide explains that auto-negotiate controls whether phase 2 SA negotiation is initiated automatically, not whether inbound and outbound SPIs are different: “By default the phase 2 security association (SA) is not negotiated until a peer attempts to send data… Auto-negotiate initiates the phase 2 SA negotiation automatically…”

So the verified answers are: C, D .

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 .

To determine the correct reasons for the adjacency failure, we must analyze the standard OSPF real-time debug output (diagnose ip router ospf all enable or diagnose sniffer packet) typically provided in this exam exhibit.

Analyze the Debug Output:

The debug output in this specific question scenario typically displays an incoming Hello packet line: OSPF: RECV[Hello]: ... auth-type 0 ...

" RECV " : Indicates the packet is coming from the Remote peer.

" auth-type 0 " : Indicates the Remote peer is sending " Null " (No) authentication.

Analyze the Failure:

The adjacency fails because the Local FortiGate is rejecting this packet.

If the Local FortiGate accepts " No Authentication " , it would match auth-type 0 and form the adjacency.

Since it is failing (and producing a debug log), the Local FortiGate must be expecting a different authentication type (Type 1 Cleartext or Type 2 MD5).

Evaluate the Options:

A. The remote peer has either OSPF cleartext or MD5 authentication configured.

Incorrect. The debug shows auth-type 0 (No Auth) coming from the remote peer.

B. There is an OSPF authentication configuration mismatch.

Correct. One side is sending " No Auth " (Remote), and the other expects " Auth " (Local). This is a definition of a mismatch.

C. The local FortiGate does not have OSPF authentication configured.

Incorrect. If the Local unit had " No Auth " configured, it would match the Remote ' s auth-type 0, and the adjacency would come up. The failure implies the Local unit does have auth configured.

D. The local FortiGate has either OSPF cleartext or MD5 authentication configured.

Correct. Because the Local unit is rejecting the " No Auth " packet from the remote peer, it confirms that the Local unit has authentication enabled (expecting Type 1 or 2).

Conclusion: The breakdown of the OSPF negotiation shows that the Remote peer is sending no authentication (Type 0), while the Local FortiGate expects authentication, resulting in a mismatch.
