Fortinet NSE8_812 Exam Domains Q&A
Certified instructors verify every question for 100% accuracy, providing detailed, step-by-step explanations for each.
Question 1
Fortinet NSE8_812
QUESTION DESCRIPTION:
You are migrating the branches of a customer to FortiGate devices. They require independent routing tables on the LAN side of the network.
After reviewing the design, you notice the firewall will have many BGP sessions as you have two data centers (DC) and two ISPs per DC while each branch is using at least 10 internal segments.
Based on this scenario, what would you suggest as the more efficient solution, considering that in the future the number of internal segments, DCs or internet links per DC will increase?
Correct Answer & Rationale:
Answer: D

Question 2
Fortinet NSE8_812
QUESTION DESCRIPTION:
Refer to the exhibits.
The exhibits show a FortiMail network topology, Inbound configuration settings, and a Dictionary Profile.
You are required to integrate a third-party ' s host service (srv.thirdparty.com) into the e-mail processing path.
All inbound e-mails must be processed by FortiMail antispam and antivirus with FortiSandbox integration. If the email is clean, FortiMail must forward it to the third-party service, which will send the email back to FortiMail for final delivery, FortiMail must not scan the e-mail again.
Which three configuration tasks must be performed to meet these requirements? (Choose three.)
Correct Answer & Rationale:
Answer: A, B, E
Explanation:
A is correct because the scan order must be changed to antispam-sandbox-content in order for FortiMail to scan the email for spam and viruses before forwarding it to the third-party service.
B is correct because the Catch-All profile must be applied to the CFInbound profile in order for FortiMail to forward clean emails to the third-party service.
E is correct because an IP policy must be created with a Source value of 100.64.0.72/32 in order to allow emails from the third-party service to be delivered to FortiMail.
The other options are not necessary to meet the requirements. Option C is not necessary because the access receive rule will already allow emails from the third-party service to be received by FortiMail. Option D is not necessary because the Catch-All profile already allows emails to be delivered to any destination.
Here are some additional details about integrating a third-party service into the FortiMail email processing path:
The third-party service must be able to receive emails from FortiMail and send them back to FortiMail.
The third-party service must be able to communicate with FortiMail using the SMTP protocol.
The third-party service must be able to authenticate with FortiMail using the SMTP AUTH protocol.
Once the third-party service is integrated into the FortiMail email processing path, all inbound emails will be processed by FortiMail as usual. If the email is clean, FortiMail will forward it to the third-party service. The third-party service will then send the email back to FortiMail for final delivery. FortiMail will not scan the email again.
Question 3
Fortinet NSE8_812
QUESTION DESCRIPTION:
What is the benefit of using FortiGate NAC LAN Segments?
Correct Answer & Rationale:
Answer: B
Explanation:
FortiGate NAC LAN Segments are a feature that allows users to assign different VLANs to different LAN segments without changing the IP address of hosts or bouncing the switch port. This provides physical isolation while maintaining firewall sessions and avoiding DHCP issues. One benefit of using FortiGate NAC LAN Segments is that it allows for assignment of dynamic address objects matching NAC policy. This means that users can create firewall policies based on dynamic address objects that match the NAC policy criteria, such as device type, OS type, MAC address, etc. This simplifies firewall policy management and enhances security by applying different security profiles to different types of devices.

Question 4
Fortinet NSE8_812
QUESTION DESCRIPTION:
Which two statements are correct on a FortiGate using the FortiGuard Outbreak Protection Service (VOS)? (Choose two.)
Correct Answer & Rationale:
Answer: C, E
Explanation:
C. The antivirus database queries FortiGuard with the hash of a scanned file. This is how the FortiGuard VOS service works. The FortiGate queries FortiGuard with the hash of a scanned file, and FortiGuard returns a list of known malware signatures that match the hash.
E. The hash signatures are obtained from the FortiGuard Global Threat Intelligence database. This is where the FortiGuard VOS service gets its hash signatures from. The FortiGuard Global Threat Intelligence database is updated regularly with new malware signatures.

Question 5
Fortinet NSE8_812
QUESTION DESCRIPTION:
A customer ' s cybersecurity department needs to implement security for the traffic between two VPCs in AWS, but these belong to different departments within the company. The company uses a single region for all their VPCs.
Which two actions will achieve this requirement while keeping separate management of each department ' s VPC? (Choose two.)
Correct Answer & Rationale:
Answer: A, D
Explanation:
To implement security for the traffic between two VPCs in AWS, while keeping separate management of each department’s VPC, two possible actions are:
Create a transit VPC with a FortiGate HA cluster, connect to the other two using VPC peering, and use routing tables to force traffic through the FortiGate cluster. This option allows the cybersecurity department to manage the transit VPC and apply security policies on the FortiGate cluster, while the other departments can manage their own VPCs and instances. The VPC peering connections enable direct communication between the VPCs without using public IPs or gateways. The routing tables can be configured to direct all inter-VPC traffic to the transit VPC.
Create a VPC with a FortiGate auto-scaling group with a Transit Gateway attached to the three VPCs to force routing through the FortiGate cluster. This option also allows the cybersecurity department to manage the security VPC and apply security policies on the FortiGate cluster, while the other departments can manage their own VPCs and instances. The Transit Gateway acts as a network hub that connects multiple VPCs and on-premises networks. The routing tables can be configured to direct all inter-VPC traffic to the security VPC.

Question 6
Fortinet NSE8_812
QUESTION DESCRIPTION:
You are responsible for recommending an adapter type for NICs on a FortiGate VM that will run on an ESXi Hypervisor. Your recommendation must consider performance as the main concern, cost is not a factor. Which adapter type for the NICs will you recommend?
Correct Answer & Rationale:
Answer: D
Explanation:
The FortiGate VM is a virtual firewall appliance that can run on various hypervisors, such as ESXi, Hyper-V, KVM, etc. The adapter type for NICs on a FortiGate VM determines the performance and compatibility of the network interface cards with the hypervisor and the physical network. There are different adapter types available for NICs on a FortiGate VM, such as E1000, VMXNET3, SR-IOV, etc. If performance is the main concern and cost is not a factor, one option is to use native ESXi networking with VMXNET3 adapter type for NICs on a FortiGate VM that will run on an ESXi hypervisor. VMXNET3 is a paravirtualized network interface card that is optimized for performance in virtual machines and supports features such as multiqueue support, Receive Side Scaling (RSS), Large Receive Offload (LRO), IPv6 offloads, and MSI/MSI-X interrupt delivery. Native ESXi networking means that the FortiGate VM uses the standard virtual switch (vSwitch) or distributed virtual switch (dvSwitch) provided by the ESXi hypervisor to connect to the physical network. This option can provide high performance and compatibility for NICs on a FortiGate VM without requiring additional hardware or software components.

Question 7
Fortinet NSE8_812
QUESTION DESCRIPTION:
Refer to the exhibits.
A customer wants to deploy 12 FortiAP 431F devices on high density conference center, but they do not currently have any PoE switches to connect them to. They want to be able to run them at full power while having network redundancy
From the FortiSwitch models and sample retail prices shown in the exhibit, which build of materials would have the lowest cost, while fulfilling the customer ' s requirements?
Correct Answer & Rationale:
Answer: D
Explanation:
the access point will require about 24.5 W of power and the 124E-FPOE has a Capacity of about 370 meaning 25x12 = 300 so you left with about 70 W on the switch meaning you can still add two more access point on that switch.
Question 8
Fortinet NSE8_812
QUESTION DESCRIPTION:
A remote worker requests access to an SSH server inside the network. You deployed a ZTNA Rule to their FortiClient. You need to follow the security requirements to inspect this traffic.
Which two statements are true regarding the requirements? (Choose two.)
Correct Answer & Rationale:
Answer: A, C
Explanation:
ZTNA supports SSH connection rules that allow remote workers to access SSH servers inside the network through an HTTPS tunnel between the client and the access proxy (FortiGate). The access proxy acts as an SSH client to connect to the real SSH server on behalf of the user, and performs host-key validation to verify the identity of the server. The user can use any SSH client that supports HTTPS proxy settings, such as PuTTY or OpenSSH.
