NEW QUESTION # 43
An administrator manages a FortiGate model that supports NTurbo
How does NTurbo acceleration enhance antivirus performance?
- A. For proxy-based inspection. NTurbo offloads traffic to the content processor.
- B. For flow-based inspection. NTurbo establishes a dedicated data path to redirect traffic between the IPS engine and FortiGate ingress and egress interfaces.
- C. For proxy-based inspection. NTurbo buffers the whole file and then sends it to the antivirus engine.
- D. For flow-based inspection. NTurbo creates two inspection sessions on the FortiGate device.
Answer: B
Explanation:
According to the FortiOS 7.6 Administration Guide and Fortinet hardware acceleration (NTurbo) documentation, the correct answer is A.
What NTurbo Is (FortiOS 7.6 - Verified)
NTurbo is a hardware-based acceleration feature available on specific FortiGate models. It is designed to improve antivirus and IPS performance when operating in flow-based inspection mode.
NTurbo works by creating a fast, optimized data path between:
FortiGate ingress interface
IPS/AV engine
FortiGate egress interface
This minimizes CPU involvement and reduces packet traversal overhead.
Why Option A Is Correct
A . For flow-based inspection, NTurbo establishes a dedicated data path to redirect traffic between the IPS engine and FortiGate ingress and egress interfaces.
This is exactly how NTurbo works, as documented:
NTurbo applies to flow-based inspection only
It accelerates IPS and antivirus scanning
It creates a dedicated fast path that bypasses unnecessary processing steps This significantly improves throughput and lowers latency This description matches Fortinet's official explanation of NTurbo.
Why the Other Options Are Incorrect
B . NTurbo creates two inspection sessions
Incorrect. NTurbo does not duplicate sessions; it optimizes the packet path.
C . NTurbo offloads traffic to the content processor (proxy-based)
Incorrect. NTurbo does not apply to proxy-based inspection and does not offload to content processors.
D . NTurbo buffers the whole file and then sends it to the antivirus engine Incorrect. Buffering entire files is a proxy-based behavior, not NTurbo.
NEW QUESTION # 44
Refer to the exhibits. The exhibits show a diagram of a FortiGate device connected to the network, and the firewall policies, VIP, and IP pool configurations on the FortiGate device.
The WAN (port2) interface has the IP address 100.65.0.101/24.
The LAN (port4) interface has the IP address 10.0.11.254/24.
The first firewall policy has NAT enabled using the IP pool. The second firewall policy is configured with a VIP as the destination address.
Which IP address will be used to source NAT (SNAT) the internet traffic coming from a workstation with the IP address 10.0.11.50?
- A. 10.0.11.254
- B. 100.65.0.102
- C. 100.65.0.101
- D. 100.65.0.200
Answer: B
Explanation:
Traffic from the workstation 10.0.11.50 going to the internet matches the Internet(1) policy (LAN
→ WAN) which has NAT enabled and is configured to use the IP Pool. The IP pool specifies the external address 100.65.0.102.
FortiGate will perform source NAT (SNAT) on the outbound traffic, translating the source IP of the workstation to 100.65.0.102.
NEW QUESTION # 45
Refer to the exhibits.
The exhibits show a diagram of a FortiGate device connected to the network, as well as the IP pool configuration and firewall policy objects.
The WAN (port1) interface has the IP address 10.200.1.1/24.
The LAN (port3) interface has the IP address 10.0.1.254/24.
Which IP address will be used to source NAT (SNAT) the traffic, if the user on Local-Client (10.0.1.10) pings the IP address of Remote-FortiGate (10.200.3.1)?
- A. 10.200.1.1
- B. 10.200.1.99
- C. 10.200.1.49
- D. 10.200.1.149
Answer: B
Explanation:
All_TCP doesn't include ICMP. So you would match rule ID 2, in which uses IP Poop remote 1.
NEW QUESTION # 46
Refer to the exhibit, which shows a partial configuration from the remote authentication server.
Why does the FortiGate administrator need this configuration?
- A. To authenticate Any FortiGate user groups.
- B. To authenticate only the Training user group.
- C. To authenticate and match the Training OU on the RADIUS server.
- D. To set up a RADIUS server Secret.
Answer: B
Explanation:
The Fortinet-Group-Name attribute is used to restrict authentication to users who belong specifically to the "Training" user group on the RADIUS server.
NEW QUESTION # 47
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 Remote-users group must be set up correctly in the FSSO configuration.
- B. No matching user account exists for this user.
- C. The Remote-users group is not added to the Destination.
- D. The Service DNS is required in the firewall policy.
Answer: D
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 # 48
Refer to the exhibits.
An administrator has observed the performance status outputs on an HA cluster for 55 seconds.
Which FortiGate is the primary?
- A. HQ-NGFW-1 with the parameter override setting
- B. HQ-NGFW-2 with the parameter priority setting
- C. HQ-NGFW-1 with the parameter memory-failover-flip-timeout setting
- D. HQ-NGFW-2 with the parameter memory-failover-threshold setting
Answer: D
Explanation:
From the HA configuration shown for HQ-NGFW-1:
set memory-based-failover enable
set memory-failover-threshold 70
set memory-failover-monitor-period 50
set memory-failover-sample-rate 10
set memory-failover-flip-timeout 60
set override disable
set priority 200
From the performance status outputs:
HQ-NGFW-1 memory used is 90% (well above the configured threshold of 70%) HQ-NGFW-2 memory used is about 48.7% (well below the threshold) What happens in FortiOS 7.6 with memory-based failover When memory-based failover is enabled, FortiGate monitors memory utilization. If the unit's memory usage stays above the configured memory-failover-threshold for the configured memory-failover-monitor-period, the cluster triggers a failover away from the unit under memory pressure.
Threshold = 70%
HQ-NGFW-1 is at 90%, so it violates the threshold.
Monitor period = 50 seconds.
The administrator observed for 55 seconds, which is longer than 50 seconds, so the condition is met for long enough to trigger failover.
The memory-failover-flip-timeout 60 is used to prevent rapid back-and-forth role changes (flapping) after a failover decision; it does not prevent the initial failover from occurring once the threshold breach persists for the monitor period.
NEW QUESTION # 49
An administrator notices that some users are unable to establish SSL VPN connections, while others can connect without any issues.
What should the administrator check first?
- A. Ensure that the affected users are using the correct port number.
- B. Ensure that the HTTPS service is enabled on SSL VPN tunnel interface
- C. Ensure that user traffic is hitting the firewall policy.
- D. Ensure that forced tunneling is enabled to reroute all traffic through the SSL VPN
Answer: A
NEW QUESTION # 50
Refer to the exhibit
A firewall policy to enable active authentication is shown.
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 Remote-users group must be set up correctly in the FSSO configuration.
- B. No matching user account exists for this user.
- C. The Remote-users group is not added to the Destination
- D. The Service DNS is required in the firewall policy.
Answer: D
Explanation:
Based on the exhibit and FortiOS 7.6 Active Authentication (captive portal) behavior, the most likely reason the user is not presented with a login prompt is that DNS is missing from the firewall policy.
What the exhibit shows
The firewall policy configured for active authentication includes:
Source: HQ_SUBNET and Remote-users
Destination: all
Services:
HTTP
HTTPS
ALL_ICMP
Security Profiles: Web filter and SSL inspection enabled
Authentication: Active (user group referenced)
DNS is not included as a service in the policy.
Why DNS is required for active authentication
In FortiOS 7.6, active authentication (captive portal) works as follows:
The user attempts to access a website using a URL (for example, www.example.com).
The client must first perform a DNS lookup to resolve the domain name.
FortiGate intercepts the initial HTTP/HTTPS request and redirects the user to the authentication portal.
If DNS traffic is blocked or not allowed:
The hostname cannot be resolved.
The HTTP/HTTPS request never properly occurs.
FortiGate has nothing to intercept, so the login prompt is never triggered.
This is explicitly documented in the FortiOS 7.6 Authentication and Captive Portal requirements, which state that DNS must be permitted for captive portal-based authentication to function correctly.
Why the other options are incorrect
A). No matching user account exists for this user
Incorrect.
If the user account did not exist, the login page would still appear, but authentication would fail after credentials are entered.
B). The Remote-users group must be set up correctly in the FSSO configuration Incorrect.
This policy is using active authentication, not FSSO.
FSSO configuration is irrelevant for active authentication login prompts.
C). The Remote-users group is not added to the Destination
Incorrect.
User groups are applied in the Source field for authentication-based policies.
Destination does not accept user groups.
NEW QUESTION # 51
When configuring firewall policies which of the following is true regarding the policy ID?
- A. A policy ID cannot be edited once a policy is created.
- B. You can create a policy in CLI with policy ID 0.
- C. A firewall policy ID identifies the order of policy execution in firewall policies.
- D. It is mandatory to provide a policy ID while creating a firewall policy regardless of GUI or CLI.
Answer: A
Explanation:
Once a firewall policy is created, its policy ID is fixed and cannot be changed; this ID uniquely identifies the policy within the FortiGate configuration.
NEW QUESTION # 52
You have created a web filter profile named restrict_media-profile with a daily category usage quota. When you are adding the profile to the firewall policy, the restrict_media-profile is not listed in the available web profile drop down.
What could be the reason?
- A. The web filter profile is already referenced in another firewall policy.
- B. The inspection mode in the firewall policy is not matching with web filter profile feature set.
- C. The naming convention used in the web filter profile is restricting it in the firewall policy.
- D. The firewall policy is in no-inspection mode instead of deep-inspection.
Answer: B
Explanation:
Web filter profiles with category usage quotas require the firewall policy to be in proxy-based (deep) inspection mode; if the inspection mode does not match this requirement, the profile will not appear in the drop-down list.
NEW QUESTION # 53
Which statement correctly describes NetAPI polling mode for the FSSO collector agent?
- A. NetAPI polling can increase bandwidth usage in large networks.
- B. The NetSessionEnum function is used to track user logouts.
- C. The collector agent uses a Windows API to query DCs for user logins.
- D. The collector agent must search Windows application event logs.
Answer: B
Explanation:
NetAPI: polls temporary sessions created on the DC when a user logs in or logs out and calls the NetSessionEnum function on Windows. It's faster than the WinSec and WMI methods; however, it can miss some login events if a DC is under heavy system load. This is because sessions can be quickly created and purged from RAM, before the agent has a chance to poll and notify FortiGate.
NEW QUESTION # 54
An administrator configured a FortiGate device to act as a collector for agentless polling mode.
What must the administrator add to the FortiGate device to retrieve AD user group information?
- A. Keycloak server
- B. TACACS server
- C. RADIUS server
- D. LDAP server
Answer: D
Explanation:
In agentless polling mode, FortiGate directly queries Active Directory to obtain user and group information. To do this, the administrator must configure an LDAP server on the FortiGate, which allows it to retrieve user group membership details from AD.
NEW QUESTION # 55
Refer to the exhibit showing a debug flow output.
Which two conclusions can you make from the debug flow output? (Choose two answers)
- A. The default gateway is configured on port2.
- B. The matching firewall policy denies the traffic.
- C. The RPF check fails.
- D. The debug flow is for UDP traffic.
Answer: A,B
Explanation:
According to the FortiOS 7.6 Troubleshooting and Administration guides, the diagnose debug flow command provides a step-by-step trace of how the FortiGate unit processes a packet.
First, the line "find a route: flag=00000000 gw-0.0.0.0 via port2" indicates that during the routing table lookup, the FortiGate matched the destination against its default route (represented by 0.0.0.0) and determined that the egress interface is port2. This confirms that the default gateway for this traffic is reachable via port2 (Statement A).
Second, the debug trace concludes with the messages "policy-2 Is matched, act-drop" and "Denied by forward policy check (policy 2)". This explicitly indicates that the packet successfully matched the criteria for firewall policy ID 2, and the action configured for that policy is set to Deny (Statement D).
Statement B is incorrect because a Reverse Path Forwarding (RPF) failure would be indicated by a specific
"reverse path check fail, drop" message, which is absent here. Statement C is incorrect because the output shows "proto=1", which corresponds to ICMP (Ping) traffic. UDP traffic would be identified as protocol 17.
NEW QUESTION # 56
An administrator manages a FortiGate model that supports NTurbo.
How does NTurbo acceleration enhance antivirus performance?
- A. For flow-based inspection, NTurbo establishes a dedicated data path to redirect traffic between the IPS engine and FortiGate ingress and egress interfaces.
- B. For proxy-based inspection, NTurbo offloads traffic to the content processor.
- C. For flow-based inspection, NTurbo creates two inspection sessions on the FortiGate device.
- D. For proxy-based inspection, NTurbo buffers the whole file and then sends it to the antivirus engine.
Answer: A
Explanation:
With flow-based inspection, NTurbo improves antivirus performance by establishing a dedicated fast data path that redirects traffic between the IPS engine and the FortiGate ingress/egress interfaces. This reduces CPU overhead, allowing antivirus scanning to happen at higher throughput without requiring full proxy-based buffering.
NEW QUESTION # 57
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 Remote-users group must be set up correctly in the FSSO configuration.
- B. No matching user account exists for this user.
- C. The Remote-users group is not added to the Destination.
- D. The Service DNS is required in the firewall policy.
Answer: D
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 # 58
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. Session helpers are disabled for denied traffic.
- C. The number of logs generated by denied traffic is reduced.
- D. Denied users are blocked for 30 minutes.
Answer: A,C
Explanation:
During the session, if a security profile detects a violation, FortiGate records the attack log immediately. 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 of 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.
NEW QUESTION # 59
Refer to the exhibits, which show the firewall policy and an antivirus profile configuration.
Why is the user unable to receive a block replacement message when downloading an infected file for the first time?
- A. Flow-based inspection is used, which resets the last packet to the user.
- B. The option to send files to FortiSandbox for inspection is enabled.
- C. The firewall policy performs a full content inspection on the file.
- D. The intrusion prevention security profile must be enabled when using flow-based inspection mode.
Answer: A
Explanation:
In Flow Based scanning, if a virus is detected, the final packet is dropped making the file unusable tot the end user. FG caches the URL of the file. If the user attempts to download again, rather than scanning the file again, the IPS engine then sends a block message to the user.
