NEW QUESTION # 38
Refer to the exhibit.

The administrator did not override the FortiGuard FODN or IP address in the FortiGate configuration Which IP address did FortiGate get when resolving the servicem,fortiguard.net name?
  • A. 96.45.33.65
  • B. 64.26.151.37
  • C. 209.22.147.36
  • D. 208.91.112.194
Answer: C
Explanation:
Based on the Fortinet FCSS - Network Security 7.6 documents and the analysis of the provided exhibits, here are the verified answers.
Questions no: 93
Verified Answer: B
Comprehensive and Detailed Explanation with all FCSS - Network Security 7.6 documents:
To determine which IP address was resolved via DNS, we must interpret the Flags column in the diagnose debug rating output provided in the exhibit:
Analyze the Flags:
Flag I (Initial): This flag indicates the IP address that was returned by the DNS query when resolving the FortiGuard FQDN (e.g., service.fortiguard.net). It acts as the "seed" or initial contact point.
Flag D (Discovered): This flag indicates servers that were not resolved via DNS but were learned dynamically from the FortiGuard network during protocol exchanges (server lists sent by the initial server).
Flag F (Failed): Indicates a server that the FortiGate tried to contact but failed.
Examine the Exhibit:
The IP address 209.22.147.36 has the flag I next to it.
The IP 208.91.112.194 has the flag D.
The IP 121.111.236.179 has the flag F.
Conclusion:
Since the question asks specifically for the IP obtained when resolving the name, we look for the "Initial" (I) flag. Therefore, 209.22.147.36 is the correct answer.
Reference:
FortiGate Security 7.6 Study Guide (Security Fabric & FortiGuard): "In diagnose debug rating, the 'I' flag stands for Initial, which is the IP address resolved by DNS. The 'D' flag stands for Discovered." Questions no: 94 Verified Answer: C, D Comprehensive and Detailed Explanation with all FCSS - Network Security 7.6 documents:
The error message iprope_in_check() check failed, drop in a debug flow indicates a failure in the Local-In Policy check. This function determines whether traffic destined to the FortiGate itself (management traffic or local services) is allowed.
C). The packet was dropped because the trusted host list is misconfigured:
Reason: If an administrator has configured Trusted Hosts (limiting administrative access to specific source IPs), and a packet arrives from an unauthorized IP, the iprope_in_check function will reject it immediately to protect the device.
D). The packet was dropped because the requested service is not enabled on FortiGate:
Reason: The most common cause for this error is that the destination interface does not have the specific service (e.g., SSH, HTTPS, PING) enabled in its set allowaccess configuration. If the service is not listening
/allowed on that port, the input check fails and drops the packet.
Why other options are incorrect:
A: If traffic is dropped by a standard firewall policy (traffic passing through the FortiGate), the debug message is typically denied by policy x or no matching policy, not an iprope (Input Property/Policy Enforcement) failure.
B: A routing issue where the source is unreachable results in a Reverse Path Forwarding (RPF) failure, typically logged 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, often due to missing allowaccess settings or Trusted Host restrictions."

NEW QUESTION # 39
While troubleshooting a FortiGate web filter issue, users report that they cannot access any websites, even though those sites are not explicitly blocked by any web filter profiles that are applied to firewall policies.

What are the three most likely reasons for this behavior? (Choose three answers)
  • A. The webfilter-force-off setting has been enabled under config system fortiguard.
  • B. The web filter cache has been cleared causing all websites to take longer to be rated.
  • C. The SSL/TLS deep inspection was configured but the browsers do not have the FortiGate certificate installed.
  • D. The DNS server is unreachable, preventing URL resolution.
  • E. The FortiGuard Web Filtering license has expired, causing FortiGate to apply the default block action.
Answer: C,D,E
Explanation:
The reported symptom-users unable to access any websites despite no explicit blocks in the profile-points to systemic connectivity or configuration issues rather than specific URL filtering rules.
* Option B (SSL/TLS Inspection): When Deep Inspection is enabled, the FortiGate acts as a Man-in- the-Middle (MitM) and re-signs server certificates using its own CA. If the clients (browsers) do not trust this CA (i.e., the certificate is not installed in their Trusted Root store), they will reject the connection with certificate errors, effectively preventing access to all HTTPS websites.
* Option D (DNS): Web browsing relies on DNS resolution. If the configured DNS server is unreachable or failing, the FortiGate (or the client) cannot resolve FQDNs to IP addresses.
Consequently, browsers will fail to load any page, resulting in a total loss of web access.
* Option E (License): If the FortiGuard Web Filtering license expires, the FortiGate can no longer query the FortiGuard Distribution Network (FDN) for ratings. By default, or if the allow-when-rating- error setting is disabled (a common security practice), the FortiGate will block all web traffic that it cannot rate, often displaying a "Web Filter Service Error" or invalid license page.
Option A is incorrect because clearing the cache only increases latency, it does not block traffic. Option C is incorrect because webfilter-force-off is typically used to disable the service (often allowing traffic to bypass checks if the service is down), rather than blocking it.

NEW QUESTION # 40
Refer to the exhibits.

FGT-1 is an area border router (ABR) that has interfaces in OSPF areas 0.0.0.0 and 0.0.0.5. FGT-3 acts as an autonomous system border router (ASBR), importing static routes into OSPF. FGT-2 is an internal router with all its interfaces belonging to area 0.0.0.5. FGT-1 is receiving all advertised routes from FGT-2, however, FGT-3 is not receiving any of the advertised routes from FGT-1. What is the most likely reason for this?
(Choose one answer)
  • A. FGT-3 and FGT-2 have not formed an OSPF adjacency yet.
  • B. FGT-2 is configured with a distribution list to block all advertised routes from FGT-3.
  • C. Area 0.0.0.5 is configured not to propagate type 5 LSAs.
  • D. IP protocol 89 is blocked between FGT-1 and FGT-3.
Answer: C
Explanation:
Comprehensive and Detailed 150 to 200 words of Explanation From Exact Extract of Network Security
7.6 documents:
The get router info ospf database brief output on FGT-2 clearly indicates that Area 0.0.0.5 is configured as a
[Stub] area.
In OSPF, a Stub Area is specifically designed to reduce the size of the Link State Database (LSDB) on internal routers. The primary behavior of a Stub area is that it does not accept Type 5 (AS External) LSAs.
* FGT-3 is the ASBR (Autonomous System Border Router) and is importing static routes, which are generated as Type 5 LSAs in the OSPF domain.
* FGT-1 acts as the ABR (Area Border Router). Because Area 0.0.0.5 is a Stub area, FGT-1 blocks these Type 5 LSAs from entering Area 0.0.0.5.
* Consequently, FGT-2 will not receive the specific external routes advertised by FGT-3. Instead, the ABR (FGT-1) injects a default route (0.0.0.0/0) into the Stub area to allow connectivity to the external world, which is visible in the database output.
While the question text mentions FGT-3 not receiving routes, the definitive configuration shown in the exhibit is the Stub area setting, which directly corresponds to the blocking of Type 5 LSA propagation (Option A).

NEW QUESTION # 41
Exhibit.

Refer to the exhibit, which shows a partial output of diagnose hardware aysinfo memory.
Which two statements about the output are true? (Choose two.)
  • A. The I/O cache, which has 641364 kB of memory allocated to it.
  • B. The value indicated next to the inactive heading represents the currently unused cache page.
  • C. There are 98908 kB of memory that will never be used.
  • D. The user space has 708880 kB of physical memory that is not used by the system.
Answer: B,D
Explanation:
The partial output from diagnose hardware sysinfo memory provides details on system RAM allocation.
According to Fortinet's technical documentation for memory troubleshooting and Linux memory management (which FortiOS is based on):
* MemFree is the portion of physical memory not currently allocated to any running process or kernel function. Thus, 708880 kB is available and can be immediately used by user-space programs or system operations.
* Inactive refers to pages in the memory cache that were previously in use for I/O or file system buffering but are now not actively referenced. These pages are retained in memory for quick access if needed again, but can be reclaimed for other memory operations if demand increases. The value 98908 kB here represents currently unused cache pages (inactive pages), ready for repurposing or deletion if the system requires more RAM.
* Cached represents the total amount of system memory allocated to cache, which includes both active and inactive cache pages. It does not, by itself, represent I/O cache exclusively, nor does "inactive" mean memory "will never be used" as the kernel can re-purpose inactive pages on demand.
