Fortinet Certification NSE7_EFW-7.2 Syllabus Exam Questions Answers

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.

The configuration line “set dpd on-idle” indicates that dead peer detection (DPD) is set to trigger only when the tunnel is idle, not actively disabled1. References: FortiGate IPSec VPN User Guide - Fortinet Document Library

From the given VPN configuration, dead peer detection (DPD) is set to 'on-idle', indicating that DPD is enabled and will be used to detect if the other end of the VPN tunnel is still alive when no traffic is detected. Hence, option C is incorrect. The configuration shows the tunnel set to type 'dynamic', which does not create separate virtual interfaces for each dial-up client (A), and it is not specified that dynamic routing will be used (B). Since this is a phase 1 configuration snippet, the routing table aspect (D) cannot be concluded from this alone.

Option D is the correct answer because it specifically blocks access to the website using TCP protocol and HTTP service, which are commonly used for web browsing. The other options either use the wrong protocol (UDP), the wrong service (DNS or SSL), or the wrong pattern (“eicar” instead of References := Configuring custom signatures | FortiGate / FortiOS 7.4.0 - Fortinet Document Library, section “Signature to block access to example.com”.

For a custom signature to be valid and savable on a FortiGate device, it must include certain mandatory fields. Severity is used to specify the level of threat that the signature represents, and attack_id is a unique identifier for the signature. Without these, the signature would not be complete and could not be correctly utilized by the FortiGate's Intrusion Prevention System (IPS).
