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.

 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 toestablish 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

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.

Metadata variables in FortiGate are created to store metadata associated with different FortiGate features. These variables can be used in various configurations and scripts to dynamically replace the variable with its actual value during processing. A: You create metadata variables on FortiGate. They are used to store metadata for FortiGate features and can be called upon in different configurations. D: They can be used as variables in scripts. Metadata variables are utilized within the scripts to dynamically insert values as per the context when the script runs.

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.

Option D is the correct answer because it specifically blocks access to the website “www.eicar.org” 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 “www.eicar.org”).  References := Configuring custom signatures | FortiGate / FortiOS 7.4.0 - Fortinet Document Library, section “Signature to block access to example.com”.

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 inability to modify the Finance address object while being able to modify the Engineering address object suggests that the Finance object is being managed by a higher authority in the Security Fabric, likely the root FortiGate. When a FortiGate is part of a Security Fabric, address objects and other configurations may be managed centrally. This aligns with the Fortinet FortiGate documentation on Security Fabric and central management of address objects.

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:

 Fail-open is a feature that allows traffic to pass through the IPS sensor without inspection when the sensor fails or is overloaded. If fail-open is set to disable, traffic will be dropped in such scenarios1. References: = IPS | FortiGate / FortiOS 7.2.3 - Fortinet Documentation

When IPS (Intrusion Prevention System) is configured, iffail-openis set to disable, it means that if the IPS engine fails, traffic will not be allowed to pass through, which can result in traffic being dropped (D). This is in contrast to a fail-open setting, which would allow traffic to bypass the IPS engine if it is not operational.

• 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: =

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.
