NSE7_EFW-7.2 Fortinet NSE 7 - Enterprise Firewall 7.2 Free Practice Exam Questions (2025 Updated)

 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

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: =

For improving reliability over a lossy IPSec tunnel, the fragmentation and fragmentation-mtu parameters should be configured. In scenarios where there might be issues with packet size or an unreliable network, setting the IPsec phase 1 to allow for fragmentation will enable large packets to be broken down, preventing them from being dropped due to size or poor network quality. The fragmentation-mtu specifies the size of the fragments. This is aligned with Fortinet's recommendations for handling IPsec VPN over networks with potential packet loss or size limitations.

The neighbor-group command in FortiOS allows for the application of common settings to a group of neighbors in OSPF, and can also be used to simplify configuration by applying common settings to both IBGP and EBGP neighbors. This grouping functionality is a part of the FortiOS CLI and is documented in the Fortinet CLI reference.

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.

Bidirectional Forwarding Detection (BFD) is a rapid protocol for detecting failures in the forwarding path between two adjacent routers, including interfaces, data links, and forwarding planes. BFD is designed to detect forwarding path failures in a very short amount of time, often less than one second, which is significantly faster than traditional failure detection mechanisms like hold-down timers in routing protocols.

Fortinet supports BFD for BGP, and it can be used over multiple hops, which allows the detection of failures even if the BGP peers are not directly connected. This functionality enhances the ability to maintain stable BGP sessions over a wider network topology and is documented in Fortinet's guides.

Option A is correct because the OSPF interface network types determine how the routers form adjacencies and exchange LSAs on a network segment. The network types must match for the routers to become neighbors1.

Option B is correct because the OSPF router IDs are used to identify each router in the OSPF domain and to establish adjacencies. The router IDs must be unique for the routers to become neighbors2.

Option E is correct because the authentication settings control how the routers authenticate each other before exchanging OSPF packets. The authentication settings must match for the routers to become neighbors3.

Option C is incorrect because the OSPF interface priority settings are used to elect the designated router (DR) and the backup designated router (BDR) on a broadcast or non-broadcast multi-access network. The priority settings do not have to be unique for the routers to become neighbors, but they affect the DR/BDR election process4.

Option D is incorrect because the OSPF link costs are used to calculate the shortest path to a destination network based on the bandwidth of the links. The link costs do not have to match for the routers to become neighbors, but they affect the routing decisions5. References: =

In the Security Fabric, only the root FortiGate sends logs to FortiAnalyzer (B). Additionally, only FortiGate devices with configuration-sync enabled receive and synchronize global Central Management Database (CMDB) objects that the root FortiGate sends (C). FortiGate uses the FortiTelemetry protocol to communicate with other FortiGates, not FortiAnalyzer (A). The last option (D) is incorrect as all FortiGates can collect and forward network topology information to FortiAnalyzer.

Option B is correct because each FortiGate in the Security Fabric can send logs to FortiAnalyzer for centralized logging and analysis12. This allows you to monitor and manage the entire Security Fabric from a single console and view aggregated reports and dashboards.

Option A is incorrect because the root FortiGate is not the only device that can send logs to FortiAnalyzer. The root FortiGate is the device that initiates the Security Fabric and acts as the central point of contact for other FortiGate devices3. However, it does not have to be the only log source for FortiAnalyzer.

Option C is incorrect because the FortiGate devices performing NAT or UTM are not the only devices that can send logs to FortiAnalyzer. These devices can perform additional security functions on the traffic that passes through them, such as firewall, antivirus, web filtering, etc4. However, they are not the only devices that generate logs in the Security Fabric.

Option D is incorrect because the last FortiGate that handled a session in the Security Fabric is not the only device that can send logs to FortiAnalyzer. The last FortiGate is the device that terminates the session and applies the final security policy5. However, it does not have to be the only device that reports the session information to FortiAnalyzer. References: =

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.

The BGP state is “Idle”, indicating that BGP is attempting to establish a TCP connection with the peer. This is the first state in the BGP finite state machine, and it means that no TCP connection has been established yet. If the TCP connection fails, the BGP state will reset to either active or idle, depending on the configuration. References: You can find more information about BGP states and troubleshooting in the following Fortinet Enterprise Firewall 7.2 documents:

Troubleshooting BGP

How BGP works

To reduce the number of BGP sessions in an IBGP network, you can use a route reflector, which acts as a focal point for IBGP sessions and readvertises the prefixes to all other peers. To configure a route reflector, you need to enable the route-reflector-client option on the neighbor-group settings of the hub device. This will make the hub device act as a route reflector server and the other devices as route reflector clients. References := Route exchange | FortiGate / FortiOS 7.2.0 - Fortinet Documentation
