Fortinet NSE7_EFW-7.2 Practice Test - Questions Answers

IKE version 2 supports the extensible authentication protocol (EAP), which allows for more flexible and secure authentication methods1.IKE version 2 also exchanges a minimum of four messages to establish a secure tunnel, which is more efficient than IKE version 12.Reference: =IKE settings | FortiClient 7.2.2 - Fortinet Documentation,Technical Tip: How to configure IKE version 1 or 2 ... - Fortinet Community

Network processors (NPs) are specialized hardware within FortiGate devices that accelerate certain security functions. One of the primary functions of NPs is to provide IPS signature matching (B), allowing for high-speed inspection of traffic against a database of known threat signatures.

In the event of an outage at 10.0.1.240, the FortiGate will choose the next server in the sequence for web filter rating requests, which is 10.0.1.244 according to the configuration shown in the exhibit. This is because the server list is ordered by priority, and the server with the lowest priority number is chosen first. If that server is unavailable, the next server with the next lowest priority number is chosen, and so on. The public FortiGuard servers are only used if the include-default-servers option is enabled and all the custom servers are unavailable.Reference:=Fortinet Enterprise Firewall Study Guide for FortiOS 7.2, page 132.

The Virtual Router Redundancy Protocol (VRRP) configuration in the exhibit indicates that 10.1.5.254 is set as the virtual IP (VRIP), commonly serving as the default gateway for the internal network (A). With vrrp-virtual-mac enabled, both FortiGates would use the same virtual MAC address, ensuring a seamless transition during failover (B). The VRRP domain does not use the physical MAC address (C), and the priority settings indicate that FortiGate-A would be the primary router by default due to its higher priority (D).

ADVPN (Auto Discovery VPN) is a feature that allows to dynamically establish direct tunnels (called shortcuts) between the spokes of a traditional Hub and Spoke architecture. The auto-discovery receiver must be set to enable on the spokes to allow them to receive NHRP messages from the hub and other spokes. NHRP (Next Hop Resolution Protocol) is used for on-demand tunnels, which are established when there is traffic between spokes. Routing is configured by enabling add-nhrp-route, not add-advpn-route.Reference:=ADVPN | FortiGate / FortiOS 7.2.0 | Fortinet Document Library,Technical Tip: Fortinet Auto Discovery VPN (ADVPN)

For the ADVPN feature to function properly on the hub, the following phase 1 parameters must be configured:

A) set auto-discovery-forwarder enable: This enables the hub to forward shortcut information to the spokes, which is essential for them to establish direct tunnels.

C) set auto-discovery-receiver enable: This allows the hub to receive shortcut offers from the spokes.

This information is corroborated by the Fortinet documentation, which explains that in an ADVPN setup, the hub must be able to both forward and receive shortcut information for dynamic tunnel creation between spokes.

The reason for the command failure when trying to set the protocol to UDP in the config system fortiguard is likely that UDP is not a protocol option in this context. The command syntax might be incorrect or the option to set a protocol for FortiGuard updates might not exist in this manner. So the correct answer is D. udp is not a protocol option.

From the command output shown in the exhibit:

B) The IKE version is 2: This can be deduced from the presence of 'ver=2' in the output, which indicates that IKEv2 is being used.

C) Both IPsec SAs are loaded on the kernel: This is indicated by the line 'npu flags=0x0/0', suggesting that no offload to NPU is occurring, and hence, both Security Associations are loaded onto the kernel for processing.

Fortinet documentation specifies that the version of IKE (Internet Key Exchange) used and the loading of IPsec Security Associations can be verified through the diagnostic commands related to VPN tunnels.

From the partial OSPF (Open Shortest Path First) configuration output:

B) The router sends grace LSAs before it restarts: This is implied by the command 'set restart-mode graceful-restart'. When OSPF is configured with graceful restart, the router sends grace LSAs (Link State Advertisements) to inform its neighbors that it is restarting, allowing for a seamless transition without recalculating routes.

Fortinet documentation on OSPF configuration clearly states that enabling graceful restart mode allows the router to maintain its adjacencies and routes during a brief restart period.
