NSE7_EFW-7.2 Questions and Answers

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.

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. References := ADVPN | FortiGate / FortiOS 7.2.0 | Fortinet Document Library, Technical Tip: Fortinet Auto Discovery VPN (ADVPN)

When deployed as a local FortiGuard Distribution Server (FDS), FortiManager functions in several capacities. It can act as an update server, a rating server, or both, providing firmware updates and FortiGuard database updates. Additionally, it plays a crucial role in VM license validation services, ensuring that the connected FortiGate devices are operating with valid licenses. However, it does not support rating requests from non-FortiGate devices nor cache firmware updates for unmanaged devices.

For an ADVPN spoke configuration shown, the corresponding hub must haveauto-discovery-senderenabled to send shortcut advertisement messages to the spokes. Also, the hub would need to haveauto-discovery-forwarderenabled 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. Theike-versiondoes not need to be reconfigured on the hub if it's already set to version 2 andauto-discovery-receiveris not necessary on the hub because it's the one sending the advertisements, not receiving.

• 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: =

The configuration output shows various global settings for a FortiGate device. The terms NP (Network Processor) and CP (Content Processor) relate to FortiGate's hardware acceleration features. However, the provided configuration output does not directly mention the status (enabled or disabled) of NPs and CPs. Typically, the command to disable or enable hardware acceleration features would specifically mention NP or CP in the command syntax. Therefore, based on the output provided, we cannot conclusively determine the status of NPs and CPs, hence option D is the closest answer since the output does not confirm that they are enabled.

• Option B is correct because the routing table shows that the tunnel interfaces have a netmask of 255.255.255.255, which indicates that net-device is enabled in the phase 1 configuration. This option allows the FortiGate to use the tunnel interface as a next-hop for routing, without adding a route to the phase 2 destination1.
• Option D is correct because the routing table does not show any routes to the phase 2 destination networks, which indicates that add-route is disabled in the phase 1 configuration. This option controls whether the FortiGate adds a static route to the phase 2 destination network using the tunnel interface as the gateway2.
• Option A is incorrect because IPSec tunnel aggregation is a feature that allows multiple phase 2 selectors to share a single phase 1 tunnel, reducing the number of tunnels and improving performance3. This feature is not related to the routing table or the phase 1 configuration.
• Option C is incorrect because OSPF is a dynamic routing protocol that can run over IPSec tunnels, but it requires additional configuration on the FortiGate and the peer device4. This option is not related to the routing table or the phase 1 configuration. References: =

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.

The commands that start with the # sign did not run because they are treated as comments in the CLI script. Incomplete commands can cause CLI scripts to fail because they are not recognized by the FortiGate device. The other options are incorrect because static routes can be added using CLI or GUI, and CLI scripts do not need to start with #!. References := Configuring custom scripts | FortiManager 7.2.0 - Fortinet Documentation, section “CLI script syntax”.
