Fortinet NSE8_812 Network Security Expert 8 Written Exam Exam Practice Test

D. The administrator must first manually map the interface for each device with a meta field.

The Jinja template in the exhibit is expecting a meta field calledWANto be set on the managed FortiGate. This meta field will specify which interface on the FortiGate should be assigned the "WAN" role. If the meta field is not set, then the template will fail.

E. The template will fail because this configuration can only be applied with a CLI or TCL script.

The Jinja template in the exhibit is trying to configure the interface role on the managed FortiGate. This type of configuration can only be applied with a CLI or TCL script. The Jinja template will fail because it is not a valid CLI or TCL script.

A is correct because the error message "The CRL is not accessible" indicates that the root FortiGate cannot access the CRL for the FortiClient EMS server. Verifying that the CRL is accessible will fix this error.

D is correct because the error message "The FortiClient EMS server is not authorized" indicates that the root FortiGate is not authorized to connect to the FortiClient EMS server. Authorizing the root FortiGate on the FortiClient EMS server will fix this error.

The other options are incorrect. Option B is incorrect because exporting and importing the FortiClient EMS server certificate to the root FortiGate will not fix the CRL error. Option C is incorrect because installing a new known CA on the Win2K16-EMS server will not fix the authorization error.

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.

Impersonation analysis is a feature that detects emails that attempt to impersonate a trusted sender, such as a company executive or a well-known brand, by using spoofed or look-alike email addresses. This feature can help prevent phishing and business email compromise (BEC) attacks. Impersonation analysis can be enabled in an antispam profile and applied to a firewall policy. References:

C. The IP address of the FortiSwitch is 10.12.240.2:This statement is correct based on the exhibit and your clarification. The exhibit lists the "IP Address" as 10.12.240.2 across multiple entries, including ports and VLANs associated with the device "sup-fgt-hw" (FortiSwitch). Your reasoning indicates that this IP is the management address of the FortiSwitch, as it is consistently shown as the IP for the device containing the ports. In Fortinet’s architecture, as described in the NSE 8 study guide, the management IP of a FortiSwitch is typically configured and visible in such configurations, especially when integrated with FortiGate and FortiNAC. The "Device" column labeling "sup-fgt-hw" further supports that this is the FortiSwitch, and the IP 10.12.240.2 is its management address. This aligns with FortiSwitch management and integration details in the NSE 8 study guide.

D. An unknown host is connected to port3:This statement is correct as the exhibit highlights port3 under the "Name" column for the device "sup-fgt-hw" with a "Rogue Host" status in the "Connection" column, an IP address of 10.12.240.2, a Default VLAN of 100, and an Operational Status of "Link Up." In FortiNAC, a "Rogue Host" indicates an unknown or unauthorized device connected to the network, which FortiNAC identifies for further action or isolation. This is consistent with FortiNAC’s capabilities for detecting and classifying unknown devices, as detailed in the NSE 8 study guide under network access control and rogue device detection.

Why A and B are incorrect:

A. A device that is modeled in FortiNAC is connected on VLAN_4093: This is incorrect based on your clarification that there is no device connected on that port—it is simply the default VLAN (4093) for that entry. The exhibit shows VLAN_4093 with a "Not Connected" status and "Link Up" operational status, but no active device connection is indicated. The NSE 8 study guide emphasizes that FortiNAC requires an active connection and device profiling for a device to be considered "connected," which is not evident here for VLAN_4093.

B. Port8 is connected to a FortiGate in FortiLink mode: This is incorrect because the exhibit shows port8 with a "Learned Uplink" status, which, as you noted, refers to any kind of uplink and does not specifically indicate FortiLink mode. FortiLink mode is a specific configuration between FortiGate and FortiSwitch requiring explicit settings, which are not mentioned or implied in the exhibit. The NSE 8 study guide clarifies that FortiLink mode involves distinct configuration details (e.g., FortiLink interfaces), which are absent here.

The OSPF configuration shown in the exhibit is using the default priority value of 1 for the interface port1. This means that FGT_3 will participate in the DR/BDR election process with the other OSPF routers on the same LAN segment. However, this is not desirable because FGT_3 is a new device that needs to be added to the OSPF network without affecting the existing DR/BDR election. Therefore, to make sure FGT_3 will establish OSPF neighbors without affecting the DR/BDR election, the priority value of the interface port1 should be changed to 0. This will prevent FGT_3 from becoming a DR or BDR and allow it to form OSPF adjacencies with the current DR and BDR. Option B shows the correct configuration that changes the priority value to 0. Option A is incorrect because it does not change the priority value. Option C is incorrect because it changes the network type to point-to-point, which is not suitable for a LAN segment with multiple OSPF routers. Option D is incorrect because it changes the area ID to 0.0.0.1, which does not match the area ID of the other OSPF routers on the same LAN segment. References:

B is correct because creating an HA setup with a second FortiDDoS 200F will provide redundancy in case one of the devices fails. This will prevent all traffic from being dropped in the event of a failure.

D is correct because the FortiDDoS 1500F has a larger throughput capacity than the FortiDDoS 200F. This means that it will be less likely to drop traffic even under heavy load.

The other options are incorrect. Option A is incorrect because changing the Adaptive Mode will not prevent the device from dropping traffic. Option C is incorrect because moving the internet connection from the SFP interfaces to the LC interfaces will not change the throughput capacity of the device.

SD-WAN is a feature that allows users to optimize network performance and reliability by using multiple WAN links and applying rules based on various criteria, such as latency, jitter, packet loss, etc. One way to ensure that the FortiGate DNS resolution times are as low as possible with the least amount of work is to configure local out traffic to use the outgoing interface based on SD-WAN rules with the interface IP and configure an SD-WAN rule to the DNS server. This means that the FortiGate will use the best WAN link available to send DNS queries to the DNS server according to the SD-WAN rule, and use its own interface IP as the source address. This avoids NAT issues and ensures optimal DNS performance. References:

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.

The CLI output shown in the exhibit indicates that FortiWeb has enabled IP Reputation feature with local techniques enabled and geographical IP policies enabled after local techniques (set geoip-policy-order after-local). IP Reputation feature is a feature that allows FortiWeb to block or allow traffic based on the reputation score of IP addresses, which reflects their past malicious activities or behaviors. Local techniques are methods that FortiWeb uses to dynamically update its own blacklist based on its own detection of attacks or violations from IP addresses (such as signature matches, rate limiting, etc.). Geographical IP policies are rules that FortiWeb uses to block or allow traffic based on the geographical location of IP addresses (such as country, region, city, etc.). Therefore, based on the output, one correct statement is that attackers can be blocked before they target the servers behind the FortiWeb. This is because FortiWeb can use IP Reputation feature to block traffic from IP addresses that have a low reputation score or belong to a blacklisted location, which prevents them from reaching the servers and launching attacks. Another correct statement is that reputation from blacklisted IP addresses from DHCP or PPPoE pools can be restored. This is because FortiWeb can use local techniques to remove IP addresses from its own blacklist if they stop sending malicious traffic for a certain period of time (set local-techniques-expire-time), which allows them to regain their reputation and access the servers. This is useful for IP addresses that are dynamically assigned by DHCP or PPPoEand may change frequently. References:

Fortinet compiles a reputation for each public IP address. Clients will have poor reputations if they have been participating in attacks, willingly or otherwise. Because blacklisting innocent clients is equally undesirable, Fortinet also restores the reputations of clients that improve their behavior. This is crucial when an infected computer is cleaned, or in DHCP or PPPoE pools where an innocent client receives an IP address that was previously leased by an attacker.

The diagnose command shown in the output is used to display information about NP6 packet descriptor queues. The output shows that there are 16 NP6 units in total, and each unit has four XAUI ports (XA0-XA3). The output also shows that there are some non-zero values in the columns PDQ ACCU (packet descriptor queue accumulated counter) and PDQ DROP (packet descriptor queue drop counter). These values indicate that there are some packet descriptor queues that have reached their maximum capacity and have dropped some packets at the XAUI ports. This could be caused by congestion or misconfiguration of the XAUI ports or the ISF (Internal Switch Fabric). References:

The output is showing a packet descriptor queue accumulated counter, which is a measure of the number of packets that have been dropped by the NP6 due to congestion. The counter will increase if there are more packets than the NP6 can handle, which can happen if the bandwidth between the ISF and the NP is not sufficient or if the HPE shaper is enabled.

The output also shows that there are packet drops at the XAUI, which is the interface between the NP6 and the FortiGate's backplane. This means that the NP6 is not able to keep up with the traffic and is dropping packets.

The other statements are not true. Host-shortcut mode is not enabled, and enabling bandwidth control between the ISF and the NP will not change the output. HPE shaper is a feature that can be enabled to improve performance, but it will not change the output of the diagnose command.
