NEW QUESTION # 55
Refer to the exhibits. A web filter profile configuration and firewall policy configuration are shown.
You are trying to access www.facebook.com, but you are redirected to a FortiGuard web filtering block page.
Based on the exhibits, what is the possible cause of the issue?
- A. For www.facebook.com, the URL filter action is incorrect.
- B. The firewall policy inspection mode is incorrect.
- C. The web filter profile feature set is configured incorrectly.
- D. The web rating override configuration is incorrect.
Answer: D
Explanation:
The web filter profile shows a URL filter override for www.facebook.com with action Monitor, which should allow access. However, the block page shows FortiGuard categorizing www.facebook.com as Malicious Websites and blocking it. This indicates that the web rating override configuration is incorrect (the override is not applied properly), so FortiGuard's default category action takes precedence and blocks the site.
NEW QUESTION # 56
Refer to the exhibits.
A diagram of a FortiGate device connected to the network, as well as the firewall policy and IP pool configuration on the FortiGate device are shown.
Two PCs. PC1 and PC2, are connected behind FortiGate and can access the internet successfully. However, when the administrator adds a third PC to the network (PC3), the PC cannot connect to the internet.
Based on the information shown in the exhibit, which two configuration options can the administrator use to fix the connectivity issue for PC3? (Choose two.)
- A. In the system settings, set Multiple Interface Policies to enable.
- B. In the firewall policy, set match-vip to enable using CLI.
- C. In the IP pool configuration, set type to overload.
- D. in the IP pool configuration, set end ipto 100.65.0.112.
Answer: C,D
Explanation:
From the exhibits:
The firewall policy has NAT enabled and is configured to Use Dynamic IP Pool.
The selected IP pool (Internet-pool) is configured as:
Type: One-to-One
External IP Range: 100.65.0.110-100.65.0.111 (only two public IPs)
PC1 and PC2 can access the internet because each one-to-one NAT mapping consumes one public IP from the pool. When PC3 is added, there is no third public IP available in the pool, so FortiGate cannot allocate a one- to-one mapping for PC3 and the session fails.
FortiOS behavior here is standard: with one-to-one IP pools, the available pool size limits how many distinct internal sources can be translated concurrently (depending on allocation and sessions), and a pool with only two IPs will not reliably support three separate hosts needing translations.
Therefore, the administrator can fix this in two valid ways:
B). In the IP pool configuration, set end ip to 100.65.0.112.
This expands the pool by adding an additional public IP address, making three public IPs available (.110, .
111, .112), so PC3 can be assigned an address for one-to-one NAT.
D). In the IP pool configuration, set type to overload.
Changing the pool type to overload enables PAT (many-to-one), allowing multiple internal hosts (PC1, PC2, PC3) to share the pool address(es) using different source ports. This removes the "one public IP per internal host" limitation inherent to one-to-one pools.
Why the other options are not correct:
A). Multiple Interface Policies is unrelated to IP pool exhaustion and does not solve NAT allocation limits.
C). match-vip affects VIP matching behavior for destination NAT/virtual IP usage and does not address the source NAT pool shortage causing PC3 to fail.
NEW QUESTION # 57
Refer to the exhibit. Review the intrusion prevention system (IPS) profile signature settings shown in the exhibit.
What can you conclude about the signature when adding the FTP.Login.Failed signature to the IPS Sensor profile?
- A. The signature setting uses a custom rating threshold
- B. The signature setting includes a group of other signatures.
- C. FortiGate stores a local copy of the packet that matches the signature.
- D. FortiGate allows this low severity signature packet and creates a log.
Answer: D
Explanation:
The IPS signature FTP.Login.Failed is configured with the action Pass and Packet logging = Enable. This means FortiGate will allow traffic that matches this signature but will also log the event, since the severity is low and blocking is not applied.
NEW QUESTION # 58
An administrator has configured the following settings.
config system settings
set ses-denied-traffic enable
end
config system global
set block-session-timer 30
end
What are the two results of this configuration? (Choose two.)
- A. A session for denied traffic is created.
- B. Denied users are blocked for 30 minutes.
- C. Session helpers are disabled for denied traffic.
- D. The number of logs generated by denied traffic is reduced.
Answer: A,D
Explanation:
"To reduce the number of log messages generated and improve performance, you can enable a session table entry of dropped traffic. This creates the denied session in the session table and, if the session is denied, all packets for that session are also denied. This ensures that FortiGate does not have to perform a policy lookup for each new packet matching the denied session, which reduces CPU usage and log generation."
"The CLI command is ses-denied-traffic. You can also set the duration for block sessions. This determines how long a session will be kept in the session table by setting block-session-timer in the CLI. By default, it is set to 30 seconds." Technical Deep Dive:
The correct answers are A and B.
When set ses-denied-traffic enable is configured, FortiGate creates a session-table entry for denied traffic. That means once traffic is denied, subsequent packets that belong to the same denied flow do not need a full policy lookup again. FortiGate can drop them immediately based on the existing denied-session entry. That directly confirms B.
Because FortiGate no longer re-evaluates every repeated denied packet in the same way, the device generates fewer logs and uses less CPU for repeated denied traffic. That is exactly why A is also correct.
Why the other two are wrong:
C is incorrect because block-session-timer 30 means 30 seconds, not 30 minutes. The denied session entry is kept in the session table for that duration.
D is incorrect because these settings do not disable session helpers. They only control how denied traffic is tracked in the session table.
In operational terms, this feature is useful when a host repeatedly retries traffic that FortiGate is already denying. Instead of doing a fresh lookup for every retry, FortiGate caches the denied decision temporarily and drops the repeated packets faster.
NEW QUESTION # 59
Refer to the exhibit to view the firewall policy.
Why would the firewall policy not block a well-known virus, for example EICAR? (Choose one answer)
- A. The firewall policy does not apply deep content inspection.
- B. Web filter is not enabled, so the firewall policy does not complement the antivirus profile.
- C. The firewall policy is not configured in proxy-based inspection mode.
- D. The action on the firewall policy is not set to DENY.
Answer: A
Explanation:
"The only security features you can apply using SSL certificate inspection mode are web filtering and application control... Note that while offering some level of security, certificate inspection does not allow FortiGate to inspect the flow of encrypted data."
"To perform SSL inspection on traffic flowing through the FortiGate device, you must allow the traffic with a firewall policy and apply an SSL inspection profile to the policy... For antivirus or IPS control, you should use a deep-inspection profile."
"When you use deep inspection, FortiGate impersonates the recipient of the originating SSL session, and then decrypts and inspects the content to find threats and block them. It then re-encrypts the content and sends it to the real recipient." Technical Deep Dive:
The exhibit shows that the policy is allowing HTTPS and the SSL/SSH inspection profile is certificate-inspection, not deep-inspection. That is the key issue. With certificate inspection, FortiGate can inspect only SSL metadata such as the certificate and SNI/hostname context; it cannot decrypt the HTTPS payload itself. Because EICAR is detected by antivirus through payload inspection, FortiGate must see the file contents. Without deep SSL inspection, the antivirus engine never gets the decrypted payload, so the file can pass even though the antivirus profile is attached.
Option A is incorrect because FortiGate firewall policies often use ACCEPT + security profile enforcement; the session can still be blocked by antivirus after policy match. Option B is incorrect because web filter is not required for antivirus detection. Option C is incorrect because the real requirement is deep SSL inspection, not specifically proxy-based mode; full SSL inspection is the deciding factor here.
In practice, to block EICAR over HTTPS, you would apply a deep-inspection SSL profile to the policy, for example:
config firewall policy
edit <policy-id>
set inspection-mode flow
set av-profile "default"
set ssl-ssh-profile "deep-inspection"
next
end
On real hardware, this also matters for performance design. Simple firewall/NAT sessions are often NP fast-pathed, but once you enable deep SSL inspection and content scanning, traffic is typically handed to CPU/WAD/content-inspection path for decryption and scanning, so throughput is lower than certificate-inspection or no-inspection.
NEW QUESTION # 60
You have configured an application control profile, set peer-to-peer traffic to Block under the Categories tab. and applied it to the firewall policy. However, your peer-to-peer traffic on known ports is passing through the FortiGate without being blocked.
What FortiGate settings should you check to resolve this issue?
- A. Network Protocol Enforcement
- B. FortiGuard category ratings
- C. Replacement Messages for UDP-based Applications
- D. Application and Filter Overrides
Answer: A
Explanation:
When the Application sensor receives traffic on that port, the protocol decoder will try to determine if the received data matches the HTTPS traffic In this case it will not match because it is P2P traffic, so this will class as violation and blocked The protocol decoder also try to determine what type of traffic it is, and even if it could not figure out it is P2P traffic, it still count as a violation because even though it does not know what it is, it knows for fact it is not HTTPS
NEW QUESTION # 61
Refer to the exhibit, which shows a firewall policy to enable active authentication.
When attempting to access an external website using an active authentication method, the user is not presented with a login prompt.
What is the most likely reason for this situation?
- A. The Service DNS is required in the firewall policy.
- B. The Remote-users group must be set up correctly in the FSSO configuration.
- C. No matching user account exists for this user.
- D. The Remote-users group is not added to the Destination.
Answer: A
Explanation:
DNS is usually used by HTTP so that people can use domain names for websites, instead of their IP address. DNS is allowed because it is a base protocol and will most likely be required to initially see proper authentication protocol traffic... However, the DNS service must still be defined in the policy as allowed, in order for it to pass.
NEW QUESTION # 62
An administrator has configured the following settings:
What are the two results of this configuration? (Choose two.)
- A. A session for denied traffic is created.
- B. Denied users are blocked for 30 minutes.
- C. Session helpers are disabled for denied traffic.
- D. The number of logs generated by denied traffic is reduced.
Answer: A,D
Explanation:
set ses-denied-traffic enable → ensures FortiGate creates a session entry even for denied traffic.
set block-session-timer 30 → sets the duration (30 seconds) that denied sessions remain in the session table. This prevents repeated logging for every packet in the same denied flow, thereby reducing the number of logs generated.
NEW QUESTION # 63
Which method allows management access to the FortiGate CLI without network connectivity?
- A. CLI console widget
- B. Telnet console
- C. Serial console
- D. SSH console
Answer: C
Explanation:
The serial console provides direct physical access to the FortiGate CLI without requiring any network connectivity. It connects via the FortiGate's console port using a serial cable, allowing administrators to perform initial configuration, recovery, or troubleshooting even if the network interfaces are down or misconfigured.
NEW QUESTION # 64
What is the primary FortiGate election process when the HA override setting is enabled?
- A. Connected monitored ports > Priority > HA uptime > FortiGate serial number
- B. Connected monitored ports > System uptime > Priority > FortiGate serial number
- C. Connected monitored ports > HA uptime > Priority > FortiGate serial number
- D. Connected monitored ports > Priority > System uptime > FortiGate serial number
Answer: A
Explanation:
When HA override is enabled, FortiGate uses the following election order: number of connected monitored ports, then device priority, followed by HA uptime, and finally FortiGate serial number as a tiebreaker.
NEW QUESTION # 65
You have configured the FortiGate device for FSSO. A user is successful in log-in to windows, but their access to the internet is denied.
What should the administrator check first?
- A. Whether the user is assigned to the correct AD group.
- B. The windows event viewer for failed login attempts.
- C. The FortiGate firewall policy settings for SSL decryption.
- D. The FortiGate FSSO active users list for user's IP address.
Answer: D
Explanation:
Checking the active users list verifies if FortiGate correctly associates the user with their IP address, ensuring proper policy enforcement for internet access.
NEW QUESTION # 66
Refer to the exhibit. Which two statements about the FortiGuard connection are true? (Choose two.)
- A. FortiGate identified the FortiGuard Server using DNS lookup.
- B. FortiGate is using the default port for FortiGuard communication.
- C. The weight increases as the number of failed packets rises.
- D. You can configure unreliable protocols to communicate with FortiGuard Server.
Answer: A,C
Explanation:
FortiGate identified the FortiGuard Server using DNS lookup → The server is shown with a private IP (10.0.1.241), which indicates FortiGate resolved it via DNS or explicit override rather than using default FortiGuard anycast servers.
The weight value reflects server reliability. It decreases with good performance and increases as packet loss or failures rise, meaning higher weight indicates more failures.
NEW QUESTION # 67
A FortiGate administrator enables SSL deep inspection on a policy but users report certificate warnings in their browsers. What is the most appropriate step to resolve this while keeping deep inspection active?
- A. Install the FortiGate CA certificate on client devices
- B. Disable HTTPS scanning in the policy
- C. Disable all security profiles on the policy
- D. Change the policy action from ACCEPT to DENY
Answer: A
Explanation:
When FortiGate performs SSL deep inspection, it substitutes the original server certificate with one it generates on the fly, signed by its internal CA. If endpoints do not trust that CA, they report errors. Deploying the FortiGate CA as a trusted root certificate on client machines resolves the warnings while retaining the ability to inspect encrypted traffic for malware, policy violations, and suspicious behavior.
NEW QUESTION # 68
The FortiGate device HQ-NGFW-1 with the IP address 10.0.13.254 sends logs to the FortiAnalyzer device with the IP address 10.0.13.125. The administrator wants to verify that reliable logging is enabled on HQ- NGFW-1.
Which exhibit helps with the verification?
- A.
- B.
- C.
- D.
Answer: A
NEW QUESTION # 69
Refer to the exhibit.
Which statement about this firewall policy list is true?
- A. The Implicit group can include more than one deny firewall policy.
- B. The firewall policies are listed by ID sequence view.
- C. LAN to WAN, WAN to LAN, and Implicit are sequence grouping view lists.
- D. The firewall policies are listed by ingress and egress interfaces pairing view.
Answer: C
Explanation:
The firewall policy list shown is displayed in the sequence grouping view, where policies are grouped based on their traffic direction - such as LAN to WAN, WAN to LAN, and Implicit. This view helps administrators quickly identify and manage policies according to their interface pairings and logical traffic flow, rather than by numerical ID order.
NEW QUESTION # 70
An administrator wanted to configure an IPS sensor to block traffic that triggers the signature set number of times during a specific time period. How can the administrator achieve the objective?
- A. Use IPS signatures, rate-mode periodical option.
- B. Use IPS filter, rate-mode periodical option.
- C. Use IPS group signatures, set rate-mode 60.
- D. Use IPS packet logging option with periodical filter option.
Answer: B
Explanation:
In FortiOS 7.6, if an administrator wants to block traffic only after an IPS signature is triggered a specific number of times within a defined time window, this must be done using IPS filters with rate-based settings.
Why option D is correct
IPS filters allow administrators to match signatures based on attributes such as:
Severity
Protocol
CVE
Signature ID
IPS filters support rate-based actions using:
rate-mode periodical
rate-count
rate-duration
With rate-mode periodical, FortiGate:
Counts how many times a signature is triggered
Within a defined time period
And applies the configured action (for example, block) once the threshold is exceeded This directly matches the requirement:
"block traffic that triggers the signature set number of times during a specific time period." Why the other options are incorrect A). IPS group signatures, set rate-mode 60Group signatures do not provide the required per-period rate-based blocking logic.
B). IPS packet logging optionLogging does not enforce blocking behavior.
C). IPS signatures, rate-mode periodical optionRate-based controls are applied via IPS filters, not directly on individual signature definitions.
