The TCP MSS (Maximum Segment Size) defines the maximum TCP payload size, excluding headers. When the firewall sets MSS to 1450 bytes, the TCP segment size is limited to this value. For IP packets, the total size includes the TCP header (20 bytes) and IP header (20 bytes), so 1450 (MSS) + 20 (TCP) + 20 (IP) = 1490 bytes, which fits within both link MTUs (1500 and 1496 bytes). Thus, the maximum IP packet size is not limited by the link MTUs but by the MSS, adjusted for headers. Options C and F (bits) are incorrect units; A and B exceed the MSS limit. Exact extract: "The TCP MSS is adjusted to prevent fragmentation... FortiGate can rewrite the MSS in TCP SYN packets to ensure the total IP packet size (including IP and TCP headers) does not exceed the configured value."

Hub-and-spoke IPsec VPN reduces the number of tunnels needed (one per spoke to hub instead of n(n-1)/2 in full mesh), simplifying configuration and routing tables with summarized routes at the hub. It does not inherently provide stronger encryption or require for redundancy (though can be made redundant). Exact extract: I want to have a way to quickly (preferably automated) setup VPN's to my 2 hubs from each spoke. However we do not want/need VPNs between spokes. Hub Configuration: Configure the FortiGate unit as the hub. Set up IPsec VPN tunnels for each spoke. Use preshared keys for authentication. The purpose of this document is to describe the requirements and general information for building a Hub & Spoke architecture using FortiGate-VM on Oracle Cloud ... The remote sites do not need to have connectivity to each other nor does the customer want them to have connectivity to each other. Given these ... This article gives a brief configuration example from one spoke to other spoke using IPsec, through the Hub firewall.

A route with a directly connected interface (no gateway) indicates the destination network is locally attached to that interface on the FortiGate. This is common for networks directly connected to the device’s interfaces. Option A is vague, B is incorrect as it’s not a dummy route, and D suggests an unknown route, which isn’t the case. Exact extract: "A directly connected route indicates that the destination network is locally attached to the interface specified in the routing table... No gateway is required for such routes as the FortiGate is directly connected to the network."
