Free and Premium Fortinet NSE8_812 Dumps Questions Answers

D is correct because Spoke1 will establish an ADVPN shortcut to Spoke2 when it detects that there is a demand for traffic between them. This is explained in the Fortinet Community article on Technical Tip: Fortinet Auto Discovery VPN (ADVPN) under Summary - ADVPN sequence of events. References:

The FEC configuration in the exhibit specifies that if the packet loss is greater than 10%, then the FEC mapping will be 8 base packets and 2 redundant packets. The download bandwidth of 500 Mbps is not greater than 950 Mbps, so the FEC mapping is not overridden by the bandwidth setting. Therefore, the FEC behavior will be 2 redundant packets for every 8 base packets.

Here is the explanation of the FEC mappings in the exhibit:

Packet loss greater than 10%: 8 base packets and 2 redundant packets.

Upload bandwidth greater than 950 Mbps: 9 base packets and 3 redundant packets.

The mappings are matched from top to bottom, so the first mapping that matches the conditions will be used. In this case, the first mapping matches because the packet loss is greater than 10%. Therefore, the FEC behavior will be 2 redundant packets for every 8 base packets.

The CLI script in option A will send the log message to the webhook server. The webhook server can then be configured to take any desired action, such as storing the log message in a database or sending an email notification.

The other options are incorrect. Option B will not send the log message to the webhook server because it does not contain thecurlcommand. Option C will send the log message to the webhook server, but it will also include the FortiGate's IP address and MAC address. This information is not necessary, and it could be used by an attacker to identify the FortiGate. Option D will not send the log message to the webhook server because it does not contain thewebhookaction.

B is correct because the OCSP check of the certificate can be combined with a certificate revocation list (CRL). This means that the FortiGate will check the OCSP server to see if the certificate has been revoked, and it will also check the CRL to see if the certificate has been revoked.

D is correct because if the OCSP server is unreachable, authentication will succeed if the certificate matches the CA. This is because the FortiGate will fall back to using the CRL if the OCSP server is unreachable.

The other options are incorrect. Option A is incorrect because OCSP checks can go to other OCSP servers, not just the FortiAuthenticator. Option C is incorrect because OCSP certificate responses can be cached by the FortiGate.

The default load balancing mode for the SD-WAN implicit rule is source IP based. This means that traffic will be load balanced evenly between the overlay members, regardless of the member's priority.

To prevent traffic from being load balanced, you can configure the priority of each overlay member to 10. This will make the member ineligible for load balancing.

The other options are not correct. Changing the load balancing mode to source-IP based will still result in traffic being load balanced. Creating a new static route with the internet sdwan-zone only will not affect the load balancing of the overlay interface. Configuring the cost in each overlay member to 10 will also not affect the load balancing, as the cost is only used when the implicit rule cannot find a match for the destination IP address.

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. References:

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:

The exhibit shows that the FortiEDR core has detected an exfiltration attack. The attack is attempting to copy files from the device to an external location. The FortiEDR core has blocked the attack, and the files have not been exfiltrated.

The exhibit also shows that the attack is using the Cobalt Strike beacon. Cobalt Strike is a penetration testing tool that can be used for both legitimate and malicious purposes. In this case, the Cobalt Strike beacon is being used to exfiltrate files from the device.

The other options are incorrect. Option A is incorrect because the attack has not been stopped. Option C is incorrect because the attack is not a ransomware attack. Option D is incorrect because the FortiEDR core has not stopped the attack.

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.

C is correct because the DHCP server used the incorrect option type for the FortiManager IP address. The option type should be 43 instead of 15, as shown in the FortiManager Administration Guide under Zero-Touch Provisioning > Configuring DHCP options for ZTP. References:

The customer wants to deploy a solution to authenticate the clients connected to a hardware switch interface of a FortiGate 400E device. A hardware switch interface is an interface that combines multiple physical interfaces into one logical interface, allowing them to act as a singleswitch with one IP address and one set of security policies. The customer wants to use 802.1X authentication for this solution, which is a standard protocol for port-based network access control (PNAC) that authenticates clients based on their credentials before granting them access to network resources. One condition that allows authentication to the client devices before assigning an IP address is that devices connected directly to ports 3 and 4 can perform 802.1X authentication. This is because ports 3 and 4 are part of the hardware switch interface named “lan”, which has an IP address of 10.10.10.254/24 and an inbound SSL inspection profile named “ssl-inspection”. The inbound SSL inspection profile enables the FortiGate device to intercept and inspect SSL/TLS traffic from clients before forwarding it to servers, which allows it to apply security policies and features such as antivirus, web filtering, application control, etc. However, before performing SSL inspection, the FortiGate device needs to authenticate the clients using 802.1X authentication, which requires the clients to send their credentials (such as username and password) to the FortiGate device over a secure EAP (Extensible Authentication Protocol) channel. The FortiGate device then verifies the credentials with an authentication server (such as RADIUS or LDAP) and grants or denies access to the clients based on the authentication result. Therefore, devices connected directly to ports 3 and 4 can perform 802.1X authentication before assigning an IP address. Another condition that allows authentication to the client devices before assigning an IP address is that client devices must have 802.1X authentication enabled. This is because 802.1X authentication is a mutual process that requires both the client devices and the FortiGate device to support and enable it. The client devices must have 802.1X authentication enabled in their network settings, which allows them to initiate the authentication process when they connect to the hardware switch interface of the FortiGate device. The client devices must also have an 802.1X supplicant software installed, which is a program that runs on the client devices and handles the communication with the FortiGate device using EAP messages. The client devices must also have a trusted certificate installed, which is used to verify the identity of the FortiGate device and establish a secure EAP channel. Therefore, client devices must have 802.1X authentication enabled before assigning an IP address. References:

A is correct because using network-overlay id allows you to configure multiple ADVPN tunnels on a single interface with a single IP address on the DC FortiGate. This is explained in the FortiGate Administration Guide under ADVPN > Configuring ADVPN > Configuring ADVPN on the hub. References:

When using inbound SSL inspection, FortiGate needs to present a certificate to the client that matches the requested domain name. If no matching certificate is found in the server-cert list, FortiGate will fall-back to the default Fortinet_CA_SSL certificate, which is self-signed and may trigger a warning on the client browser.

The Server Pool in the exhibit is configured with a weight of 20 for server 1 and a weight of 60 for server 2. This means that server 1 will receive 20% of the sessions and server 2 will receive 75% of the sessions.

The following formula is used to calculate the load balancing between servers in a Server Pool:

weight_of_server_1 / (weight_of_server_1 + weight_of_server_2)

In this case, the formula is:

20 / (20 + 60) = 20 / 80 = 0.25 = 25%

Therefore, server 1 will receive 25% of the sessions and server 2 will receive 75% of the sessions.

The configuration excerpt shows that the SNAT source port partitioning behavior is set to dynamic. This means that the FortiGate will dynamically distribute SNAT source ports to operating FPCs or FPMs. This ensures that active sessions are not interrupted if an FPC or FPM goes down.

The other options are incorrect. Option B is incorrect because the default SNAT configuration is static. Option C is incorrect because the configuration excerpt does not specify that SNAT source ports are statically distributed. Option D is incorrect because the SNAT source ports are not evenly distributed across chassis slots.

Here are some additional details about SNAT source port partitioning behavior:

SNAT source port partitioning behavior can be set to dynamic or static.

The default SNAT configuration is static.

Dynamic SNAT source port partitioning ensures that active sessions are not interrupted if an FPC or FPM goes down.

Static SNAT source port partitioning can improve performance by reducing the number of SNAT lookups.

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 belongto 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 PPPoE and may change frequently. References:

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. References:

The FortiGate 6000F has 24 1/10/25-Gbps SFP28 data network interfaces (1 to 24). These interfaces are divided into the following interface groups: 1 to 4, 5 to 8, 9 to 12, 13 to 16, 17 to 20, and 21 to 24. The ports 25 to 28 are 40/100-Gbps QSFP28 data network interfaces.

The initial connection should be made to any interface between ports 1 to 4. This is because the ports 21 to 24 are part of the same interface group, and changing the speed of one of these ports will affect the speeds of all of the ports in the group. The ports 5 to 8 are also part of the same interface group, so they should not be used for the initial connection.

The new hardware module that will be installed in the switch will provide higher speed ports. When this module is installed, the speed of the ports 21 to 24 will be increased. However, this will not affect the ports 1 to 4, because they are not part of the same interface group.

Therefore, the initial connection should be made to any interface between ports 1 to 4, in order to ensure that the FortiGate interface connected to the switch does not affect any other port when the new module is installed and the new port speed is defined.
