NEW QUESTION # 19
Which two statements are correct when FortiGate enters conserve mode? (Choose two.)
- A. FortiGate continues to run critical security actions, such as quarantine.
- B. FortiGate halts complete system operation and requires a reboot to regain available resources.
- C. FortiGate refuses to accept configuration changes.
- D. FortiGate continues to transmit packets without IPS inspection when the fail-open global setting in IPS is enabled.
Answer: C,D
Explanation:
In conserve mode, FortiGate restricts configuration changes to preserve system stability. When IPS fail-open is enabled, FortiGate continues forwarding traffic without IPS inspection during resource constraints (conserve mode).
NEW QUESTION # 20
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. FortiGate allows this low severity signature packet and creates a log.
- C. The signature setting includes a group of other signatures.
- D. FortiGate stores a local copy of the packet that matches the signature.
Answer: B
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 # 21
You are analyzing connectivity problems caused by intermediate devices blocking traffic in SSL VPN environment.
In which two ways can you effectively resolve the problem? (Choose two.)
- A. You can turn off IKE fragmentation to fix large certificate negotiation problems.
- B. You should use IPsec to solve issues with fragment drops and large certificate exchanges.
- C. You can use SSL VPN tunnel mode to prevent problems with blocked ESP and UDP ports (500 or 4500).
- D. You can configure a hub-and-spoke topology with SSL VPN tunnels to bypass blocked UDP ports.
Answer: A,C
Explanation:
Disabling IKE fragmentation helps resolve issues caused by intermediate devices blocking large fragmented packets during certificate negotiation.
Using SSL VPN tunnel mode encapsulates traffic over HTTPS, bypassing blocks on ESP and UDP ports commonly used by IPsec.
NEW QUESTION # 22
An administrator wants to analyze and manage digital certificates to prevent browser warnings when users connect to the SSL VPN portal.
Which two statements describe how to correctly do this? (Choose two.)
- A. The administrator can import the FortiGate self-signed certificate into each user's browser as a trusted certificate.
- B. The administrator can rely on the default FortiGate self-signed certificate to prevent all security warnings in the browser.
- C. The administrator can use a publicly trusted certificate from a known certificate authority (CA) to stop browser warnings.
- D. The administrator must disable HTTPS administrative access entirely to avoid certificate warnings.
Answer: A,C
Explanation:
Using a publicly trusted certificate from a known CA prevents browser warnings without additional user action.
Importing the FortiGate self-signed certificate into users' browsers as trusted eliminates warnings caused by untrusted certificates.
NEW QUESTION # 23
Which two statements are true regarding FortiGate HA configuration synchronization? (Choose two.)
- A. Checksums of devices will be different from each other because some configuration items are not synced to other HA members.
- B. Incremental configuration synchronization can occur only from changes made on the primary FortiGate device.
- C. Checksums of devices are compared against each other to ensure configurations are the same.
- D. Incremental configuration synchronization can occur from changes made on any FortiGate device within the HA cluster.
Answer: C,D
Explanation:
After the initial synchronization is complete, whenever a change is made to the configuration of an HA cluster device (primary or secondary), incremental synchronization sends the same configuration change to all other cluster devices over the HA heartbeat link.
NEW QUESTION # 24
Refer to the exhibit. The predefined deep-inspection and custom-deep-inspection profiles exclude some web categories from SSL inspection, as shown in the exhibit.
For which two reasons are these web categories exempted? (Choose two.)
- A. The FortiGate temporary certificate denies the browser's access to websites that use HTTP Strict Transport Security.
- B. The resources utilization is optimized because these websites are in the trusted domain list on FortiGate.
- C. The legal regulation aims to prioritize user privacy and protect sensitive information for these websites.
- D. These websites are in an allowlist of reputable domain names maintained by FortiGuard.
Answer: A,C
Explanation:
FortiGate's temporary SSL certificate may cause access denial to sites using HTTP Strict Transport Security (HSTS), so such sites are exempted from deep SSL inspection. Legal regulations require exemption of certain categories to protect user privacy and sensitive information, so these web categories are excluded from SSL inspection.
NEW QUESTION # 25
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 forced tunneling is enabled to reroute all traffic through the SSL VPN
- B. Ensure that the affected users are using the correct port number.
- C. Ensure that the HTTPS service is enabled on SSL VPN tunnel interface
- D. Ensure that user traffic is hitting the firewall policy.
Answer: D
Explanation:
If user traffic is not matching the appropriate firewall policy that permits SSL VPN, users will be unable to establish connections, making this the first aspect to verify.
NEW QUESTION # 26
A remote user reports slow SSL VPN performance and frequent disconnections. The user is located in an area with poor internet connectivity.
What setting should the administrator adjust to improve the user's experience?
- A. Increase the session timeout for inactive sessions.
- B. Change the SSL VPN port to a non-standard port.
- C. Configure the DTLS timeout to accommodate high-latency connections.
- D. Enable split tunneling to reduce VPN traffic.
Answer: C
Explanation:
Adjusting the DTLS timeout helps maintain SSL VPN stability and performance in environments with poor or high-latency internet connectivity by allowing more time for packet retransmissions before dropping the connection.
NEW QUESTION # 27
Which three statements explain a flow-based antivirus profile? (Choose three.)
- A. Flow-based inspection optimizes performance compared to proxy-based inspection.
- B. The IPS engine handles the process as a standalone.
- C. If a virus is detected, the last packet is delivered to the client.
- D. FortiGate buffers the whole file but transmits to the client at the same time.
- E. Flow-based inspection uses a hybrid of the scanning modes available in proxy-based inspection.
Answer: A,D,E
Explanation:
Flow-based antivirus buffers the entire file while simultaneously transmitting data to the client to minimize latency.
Flow-based inspection combines multiple scanning techniques from proxy-based modes for efficient detection.
Flow-based inspection provides better performance by processing traffic on the fly without full proxy overhead.
NEW QUESTION # 28
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: A
Explanation:
The HA configuration shows that override is disabled (set override disable), but despite this, HQ- NGFW-1 has the higher priority (200) and is acting as the primary, as indicated by its higher resource usage and uptime. Override allows the device with higher priority to take over as primary, so HQ- NGFW-1 is the primary device.
NEW QUESTION # 29
Refer to the exhibit. An administrator has configured an Application Overrides for the ABC.Com application signature and set the Action to Allow. This application control profile is then applied to a firewall policy that is scanning all outbound traffic. Logging is enabled in the firewall policy. To test the configuration, the administrator accessed the ABC.Com web site several times.
Why are there no logs generated under security logs for ABC.Com?
- A. The ABC.Com is configured under application profile, which must be configured as a web filter profile.
- B. The ABC.Com Type is set as Application instead of Filter.
- C. The ABC.Com is hitting the category Excessive-Bandwidth.
- D. The ABC.Com Action is set to Allow.
Answer: D
Explanation:
When the action is set to Allow in an application override, traffic matching this override is allowed without generating security logs because it bypasses deeper inspection and blocking.
NEW QUESTION # 30
Refer to the exhibits. An administrator configured both members of an HA cluster at the same time. After one week of monitoring, the administrator wants to verify the HA failover performance.
How can the administrator force a failover?
- A. The administrator must increase the HA priority on HQ-NGFW-2.
- B. The administrator must set the parameter override to enable on HQ-NGFW-2.
- C. The administrator must reset the HA uptime on HQ-NGFW-1.
- D. The administrator must set the monitored port to down on HQ-NGFW-1.
Answer: D
Explanation:
Both FortiGates are in an active-passive (a-p) HA cluster with override disabled. This means failover is triggered only if the primary (HQ-NGFW-1) becomes unavailable or monitored interfaces fail. To test failover performance, the administrator can set the monitored interface (port1) down on HQ-NGFW-1, which will force a failover to HQ-NGFW-2.
NEW QUESTION # 31
Refer to the exhibit. The administrator configured SD-WAN rules and set the FortiGate traffic log page to display SD-WAN-specific columns: SD-WAN Quality and SD- WAN Rule Name.
FortiGate allows the traffic according to policy ID 1 placed at the top. This is the policy that allows SD-WAN traffic. Despite these settings, the traffic logs do not show the name of the SD-WAN rule used to steer those traffic flows.
What could be the reason?
- A. There is no application control profile applied to the firewall policy.
- B. Destinations in the SD-WAN rules are configured for each application, but feature visibility is not enabled.
- C. FortiGate load balanced the traffic according to the implicit SD-WAN rule.
- D. SD-WAN rule names do not appear immediately. The administrator must refresh the page.
Answer: C
Explanation:
The SD-WAN traffic log does not display an SD-WAN rule name because the traffic is being forwarded by the implicit SD-WAN rule. If no explicit SD-WAN rule matches the traffic, FortiGate falls back to the default implicit rule, which balances traffic based on the configured strategy (such as volume or sessions). Since no explicit rule applied, the rule name field remains blank in the logs.
NEW QUESTION # 32
Which two statements describe characteristics of automation stitches? (Choose two.)
- A. Multiple actions can run in parallel.
- B. An automation stitch can have multiple triggers.
- C. Actions involve only devices included in the Security Fabric.
- D. Triggers can involve external connectors.
Answer: A,D
Explanation:
Automation stitches can execute multiple actions concurrently (in parallel). Triggers for automation stitches can come from external connectors beyond just Fortinet devices.
NEW QUESTION # 33
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. No matching user account exists for this user.
- C. The Remote-users group is not added to the Destination.
- D. The Remote-users group must be set up correctly in the FSSO configuration.
Answer: A
Explanation:
For active authentication (such as captive portal) to trigger, the FortiGate must intercept the user's initial web request. This requires DNS traffic to pass through the FortiGate so it can redirect the request to the login page. If the firewall policy does not include the DNS service, the user's browser resolves domains directly, and the authentication portal is never triggered.
NEW QUESTION # 34
An administrator has configured a dialup IPsec VPN on FortiGate with add-route enabled.
However, the static route is not showing in the routing table.
Which two statements about this scenario are correct? (Choose two.)
- A. The administrator must ensure phase 2 is successfully established.
- B. The administrator must enable a dynamic routing protocol on the dialup interface.
- C. The administrator must define the remote network correctly in the phase 2 selectors.
- D. The administrator must use a policy route instead of a static route for add-route to work properly.
Answer: A,C
Explanation:
The administrator must ensure phase 2 is successfully established → The static route for the dialup VPN is only added after Phase 2 negotiation completes successfully.
The administrator must define the remote network correctly in the phase 2 selectors → The add- route feature installs a route based on the Phase 2 selectors; if they are incorrect, no route will appear in the routing table.
NEW QUESTION # 35
Refer to the exhibit. The NOC team connects to the FortiGate GUI with the NOC_Access admin profile. They request that their GUI sessions do not disconnect too early during inactivity. What must the administrator configure to answer this specific request from the NOC team?
- A. Increase the admintimeout value under config system accprofile NOC_Access.
- B. Increase the offline value of the Override Idle Timeout parameter in the NOC_Access admin profile.
- C. Move NOC_Access to the top of the list to ensure all profile settings take effect.
- D. Ensure that all NOC_Access users are assigned the super_admin role to guarantee access
Answer: A
Explanation:
The admintimeout setting in the admin access profile controls the inactivity timeout for GUI sessions. Increasing this value will extend the session duration before automatic disconnection.
NEW QUESTION # 36
Refer to the exhibit. Why did FortiGate drop the packet?
- A. It matched the default implicit firewall policy.
- B. It failed the RPF check.
- C. The next-hop IP address is unreachable.
- D. It matched an explicitly configured firewall policy with the action DENY.
Answer: A
Explanation:
The debug trace output shows that the packet was "Denied by forward policy check (policy 0)." In FortiGate, policy ID 0 corresponds to the default implicit deny policy. This means that if a packet does not match any configured firewall policies, it is denied by the default implicit policy.
