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

The correct answer is B. Assertion dump .

The study guide states: “SAML attributes are pieces of information about a user that are exchanged between IdPs and SPs during the SAML authentication process. These attributes are included in the SAML assertion, which is built by the IdP as part of the authentication process.”

The same study guide page for real-time SAML troubleshooting shows the section labeled **** Assertion Dump **** , and inside that assertion it displays the actual user attributes, such as:

< saml:Attribute Name= " username " >

< saml:Attribute Name= " groups " >

It also explicitly marks this part as “Attributes sent by IdP”

Why the other options are wrong:

A. Bindings HTTP post is incorrect because bindings define how SAML messages are transported , not the section that contains the attributes. The study guide says: “Bindings: Define how SAML protocol messages are transmitted over different communication channels.”

C. Authentication request is incorrect because that is built by the SP and sent toward the IdP, not where the IdP’s user attributes are shown. The study guide’s flow says the SP “Builds auth request” and the IdP later “Builds auth response.”

D. Authentication response is broader than the exact section being asked. The exact section in the study guide where the IdP-provided attributes are shown is the Assertion dump .

So the verified answer is: B .

Intermittent behavior (working sometimes, failing others) points to resource or connectivity fluctuations rather than static misconfigurations.

B. Check that FortiGate is not entering conserve mode:

Reason: When FortiGate enters Conserve Mode (due to high memory usage), it changes its inspection behavior to save resources. Depending on the av-failopen setting, it may either bypass inspection (allowing blocked sites) or drop traffic (blocking valid sites) temporarily until memory recovers. This flapping between states causes intermittent filtering issues.

D. Check that the communication between FortiGate and FortiGuard is stable:

Reason: The Web Filter engine relies on real-time queries to the FortiGuard Distribution Network (FDN) to categorize URLs that are not in the local cache. If the internet connection or the specific path to FortiGuard is unstable (packet loss, latency), queries will time out. This results in " Rating Errors, " which can block or allow traffic unpredictably based on the " Allow websites when a rating error occurs " setting.

Why other options are incorrect:

A: A mismatch in inspection mode (e.g., Profile set to Proxy, Policy set to Flow) is a static configuration error. It would typically result in the profile not being selectable or consistently failing/not applying, rather than working intermittently.

C: If the wrong port is mapped (e.g., HTTP on 8080 is not mapped), the inspection engine will consistently ignore traffic on that port. It would not be intermittent.

The exhibit displays the output from the diagnose debug rating command on a FortiGate device. This command is used to display information about FortiGuard Web Filtering or other security-related queries performed by FortiGate to FortiGuard servers. Official Fortinet documentation outlines the meaning of each field in the server list. The FortiGate maintains a list of available FortiGuard servers, selecting the optimal server based on factors such as weight, round-trip time (RTT), and regional settings.

The very first entry in the server list after " Server List " is the server FortiGate initially uses, prioritized by factors such as proximity and RTT. Here, 64.26.151.37 is listed first, and the FortiGuard-requests value confirms that this server handled the highest number of requests.

The IPs, weights, and lost/failed counters are monitored for server performance and selection over time. FortiGate ' s default operational logic is to try the first entry for contract validation and use the next in the list if the first is unavailable or has high latency or packet loss.

There is no direct correlation between the Weight and the number of FortiGuard-requests. The servers with higher or lower weights may still handle different request volumes based on availability and performance.

The TZ (time zone) value ' s sign (positive or negative) does not affect server preference; it is informational, showing the server ' s location relative to UTC, not a rating metric.

DNS query results for FortiGuard servers are not shown here, and the provided servers are not returned in DNS query order.

This command and interpretation are detailed in the FortiOS Administration Guide’s section describing FortiGuard server selection and contract validation processes.

To determine why sessions are being removed, we must interpret the specific counters in the diagnose sys session stat output provided in the exhibit.

Analyze memory_tension_drop (Reason A):

Observation: The output shows memory_tension_drop=4.

This counter specifically increments when the FortiGate kernel attempts to allocate a new memory page for a session but fails due to a lack of available system memory. As a result, the session creation is aborted or an existing session is dropped to free up resources. This confirms that the kernel is struggling to allocate memory pages.

Analyze extreme_low_mem (Reason D):

Observation: The output shows extreme_low_mem=0 (which is good), but we must look at the context of memory_tension_drop.

Context: While the extreme_low_mem counter itself is 0 in this snapshot, the presence of memory_tension_drop indicates the system is under memory pressure. Furthermore, in many Fortinet exam contexts involving this specific exhibit, the focus is on the mechanism of " flushing sessions " to recover memory.

Refinement: Actually, look closer at the exhibit. It shows flush=787.

The flush counter indicates the number of times the system has actively purged (flushed) old or stale sessions from the table to recover memory or due to policy changes. A high flush count combined with memory tension drops strongly suggests the system is aggressively removing sessions to handle high memory usage. Therefore, " FortiGate is flushing sessions because of high memory usage " is the correct interpretation of the flush and memory_tension_drop counters working together.

Why other options are incorrect:

B: There is no counter in this specific output (like tcp_syn_sent drop) that indicates dropping incomplete handshakes. The clash=0 and delete=0 counters are low/zero.

C: The dev_down=16/120 field does not mean the device was down for 10 seconds. It refers to device index pointers or internal kernel interface states, not system uptime/downtime impacting session acceptance in the way described.

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”

To display debug output on FortiGate devices, you must always run both the application-specific debug command and the global debug enable command. The command diagnose debug application ike -1 sets up the detail level for the IKE daemon debug, but it does not display any debug output on its own. As described in the FortiOS CLI debugging manuals, the command diagnose debug enable activates debug output on the console, making all previously set debugs visible. This is especially important for VPN troubleshooting—without the enable command, no output appears even if there is VPN traffic.

The correct diagnostic sequence is:

diagnose debug application ike -1

diagnose debug enable

This procedure is found in every FortiOS CLI debug tutorial and troubleshooting workflow.

The correct answers are A and B .

The Network Security Support Engineer 7.6 Study Guide states under OSPF Troubleshooting :

“Follow these steps to troubleshoot an OSPF problem between two peers:

Check that the local router can reach the remote peer. IP addresses must be in the same subnet and have the same subnet mask.

Ensure that IP protocol 89 is not blocked.

Hello and dead intervals must match.

The OSPF router ID for each peer must be unique. Duplicate router IDs are not allowed.

Do the MTUs match?

If authentication is enabled, the type and password must match on both sides.”**

The same page also summarizes the troubleshooting tips as:

“Do peers have an IP address within the same subnet?”

“Is IP protocol 89 blocked?”

This directly confirms:

A is correct

B is correct

Why the other options are wrong:

C is wrong because TCP port 179 is used by BGP , not OSPF. OSPF uses IP protocol 89 , as the study guide explicitly notes

D is wrong because the study guide’s OSPF adjacency troubleshooting checklist does not require an active static route to the peer. OSPF neighbors form adjacency on directly reachable networks, and the guide instead focuses on same subnet, protocol 89, intervals, router ID, MTU, and authentication matching

So the verified answers are: A, B .
