NSE7_EFW-7.2 Fortinet NSE 7 - Enterprise Firewall 7.2 Questions and Answers

The access to www.facebook.com is blocked based on the URL Filter configuration.  In the exhibit, it shows that the URL “www.facebook.com” is specifically set to “Block” under the URL Filter section 1. References := Fortigate: How to configure Web Filter function on Fortigate, Web filter | FortiGate / FortiOS 7.0.2 | Fortinet Document Library, FortiGate HTTPS web URL filtering … - Fortinet … - Fortinet Community

Option A is correct because the address object on the tool FortiGate will not be synchronized with the downstream devices if it has fabric-object set to disable. This option controls whether the address object is shared with other FortiGate devices in the Security Fabric or not1.

Option C is correct because the downstream FortiGate will not receive the address object from the tool FortiGate if it has fabric-object-unification set to local. This option controls whether the downstream FortiGate uses the address objects from the root FortiGate or its own local address objects2.

Option B is incorrect because the root FortiGate has configuration-sync set to enable by default, which means that it will synchronize the address objects with the downstream devices unless they are disabled by the fabric-object option3.

Option D is incorrect because the downstream FortiGate has configuration-sync set to local by default, which means that it will receive the address objects from the root FortiGate unless they are overridden by the fabric-object-unification option4. References: =

For an ADVPN spoke configuration shown, the corresponding hub must have auto-discovery-sender enabled to send shortcut advertisement messages to the spokes. Also, the hub would need to have auto-discovery-forwarder enabled if it is to forward on those shortcut advertisements to other spokes. This allows the hub to inform all spokes about the best path to reach each other. The ike-version does not need to be reconfigured on the hub if it's already set to version 2 and auto-discovery-receiver is not necessary on the hub because it's the one sending the advertisements, not receiving.

To configure a loopback as the BGP source, you need to set the “ebgp-enforce-multihop” and “update-source” parameters in the BGP configuration. The “ebgp-enforce-multihop” allows EBGP connections to neighbor routers that are not directly connected, while “update-source” specifies the IP address that should be used for the BGP session1. References := BGP on loopback, Loopback interface, Technical Tip: Configuring EBGP Multihop Load-Balancing, Technical Tip: BGP routes are not installed in routing table with loopback as update source

In the ADVPN configuration for BGP, you should specify the prefix that the neighbors can advertise. Option A is correct as you would configure the BGP network prefix that should be advertised to the neighbors, which matches the BGP network in the diagram. Option C is also correct since you should reference the neighbor group configured for the ADVPN setup within the BGP configuration.

The primary purpose of configuring a main link between the devices is to synchronize session information so that if one unit fails, the other can continue processing traffic without dropping active sessions.

A. To have both sessions and configuration synchronization in layer 2.This is incorrect because FGSP is used for session synchronization, not configuration synchronization.

B. To load balance both sessions and configuration synchronization between layer 2 and 3.FGSP does not perform load balancing and is not used for configuration synchronization.

C. To have only configuration synchronization in layer 3.The main link is not used solely for configuration synchronization.

D. To have both sessions and configuration synchronization in layer 3.The main link in an FGSP setup is indeed used to synchronize session information across the devices, and it operates at layer 3 since it uses IP addresses to establish the peering.

From the OSPF interface command output, we can conclude that the port3 network has more than one OSPF router because the Neighbor Count is 2, indicating the presence of another OSPF router besides NGFW-1. Additionally, we can deduce that the interfaces of the OSPF routers match the MTU value configured as 1500, which is necessary for OSPF neighbors to form adjacencies. The MTU mismatch would prevent OSPF from forming a neighbor relationship.

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.

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.

To enable AD-VPN, you need to edit an SD-WAN overlay template and enable the Auto-Discovery VPN toggle. This will automatically add the required settings to the IPsec template and the BGP template. You cannot enable AD-VPN directly in the IPsec phase 1 settings using VPN Manager. References := ADVPN | FortiManager 7.2.0 - Fortinet Documentation

 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. References: = IKE settings | FortiClient 7.2.2 - Fortinet Documentation, Technical Tip: How to configure IKE version 1 or 2 … - Fortinet Community
