Fortinet NSE7_EFW-7.2 Fortinet NSE 7 - Enterprise Firewall 7.2 Exam Practice Test
Question 1
Refer to the exhibit, which shows config system central-management information.
Which setting must you configure for the web filtering feature to function?
Answer : D
For the web filtering feature to function effectively, the FortiGate device needs to have a server configured for rating services. The rating option in the server-type setting specifies that the server is used for URL rating lookup, which is essential for web filtering. The displayed configuration does not list any FortiGuard web filtering servers, which would be necessary for web filtering. The setting set include-default-servers disable indicates that the default FortiGuard servers are not being used, and hence, a specific server for web filtering (like securewf.fortiguard.net) needs to be configured.
Question 2
Which two statements about the BFD parameter in BGP are true? (Choose two.)
Answer : A, C
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.
Question 3
Which two statements about IKE version 2 fragmentation are true? (Choose two.)
Answer : A, D
In IKE version 2, not all packets are fragmentable. Only certain messages within the IKE negotiation process can be fragmented. Additionally, there is a limit to the number of fragments that IKE version 2 can handle, which is 128. This is specified in the Fortinet documentation and ensures that the IKE negotiation process can proceed even in networks that have issues with large packets. The reassembly timeout and the layer at which fragmentation occurs are not specified in this context within Fortinet documentation.
Question 4
You want to improve reliability over a lossy IPSec tunnel.
Which combination of IPSec phase 1 parameters should you configure?
Answer : C
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.
Question 5
Which two statements about ADVPN are true? (Choose two.)
Answer : C, D
C) The hub adds routes based on IKE negotiations: This is part of the ADVPN functionality where the hub learns about the networks behind the spokes and can add routes dynamically based on the IKE negotiations with the spokes.
D) You must configure phase 2 quick mode selectors to 0.0.0.0 0.0.0.0: This wildcard setting in the phase 2 selectors allows any-to-any tunnel establishment, which is necessary for the dynamic creation of spoke-to-spoke tunnels.
These configurations are outlined in Fortinet's documentation for setting up ADVPN, where the hub's role in route control and the use of wildcard selectors for phase 2 are emphasized to enable dynamic tunneling between spokes.
Question 6
Exhibit.
Refer to the exhibit, which contains the partial ADVPN configuration of a spoke.
Which two parameters must you configure on the corresponding single hub? (Choose two.)
Answer : A, C
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.

Question 7
Exhibit.
Refer to the exhibit, which provides information on BGP neighbors.
Which can you conclude from this command output?
Answer : C
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.Reference: You can find more information about BGP states and troubleshooting in the following Fortinet Enterprise Firewall 7.2 documents:
