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."

BGP path selection follows a specific order of attributes to determine the best path. The process prefers the path with the highest local preference first, as it is one of the earliest steps in the decision process. Local preference is used within an AS to influence outbound traffic. Only if local preferences are equal does it move to the next criteria, such as shortest AS path. The AS path length is considered after local preference, MED after that, and eBGP over iBGP even later. Therefore, among the options, the highest local preference (D) is the most preferred criterion. The original document's answer B is incorrect based on standard BGP selection rules implemented in Fortinet. Exact extract: This article describes the BGP route selection process. Scope FortiGate. Solution Consider only routes with no AS loops and a valid next hop. BGP makes routing decisions based on path, network policies and rulesets ... select the route with the lowest router ID as the best path. Network. Type. To achieve this, multiple route selection techniques can be used. Some are protocol-agnostic (for example, weight) and others are protocol-specific (for example ...).

In a FortiGate HA cluster (active-active or active-passive), if the primary unit fails, a secondary unit automatically takes over as the primary, ensuring continuity of traffic with minimal disruption. Option A is incorrect as traffic continues, C is incorrect as the mode doesn’t change post-failure, and D is unrelated. Exact extract: "In a FortiGate HA cluster, if the primary unit fails, a secondary unit is elected as the new primary, taking over all roles to maintain traffic flow and session continuity."
