Link aggregation, also known as IEEE 802.3ad or 802.1ax, enables the binding of multiple physical interfaces to form a single logical interface, which increases the overall bandwidth and provides redundancy. This is achieved by combining the bandwidth of the individual links into one aggregated link. For example, if two 1Gbps interfaces are aggregated, the logical link can provide up to 2Gbps bandwidth. This configuration is commonly used in FortiGate devices to enhance network performance without replacing hardware. The option B correctly describes this by stating "Increase bandwidth by binding physical interfaces into a single channel," which aligns with the official description. Incorrect options include A, which is vague and does not specify the method of binding multiple interfaces; C, which is the opposite of the purpose; and D, which is invalid. Exact extract: Link aggregation (IEEE 802.3ad/802.1ax) enables you to bind two or more physical interfaces together to form an aggregated (combined) link. This new link ... Link aggregation combines multiple physical interfaces into a single logical interface, increasing bandwidth and link redundancy. Traffic is distributed evenly.

The ‘set webfilter-profile’ command applies a web filtering profile to a firewall policy, enabling URL blocking or allowing based on categories or specific URLs. It does not enable DPI (B), configure proxies (C), or set authentication (D). Exact extract: "The ‘set webfilter-profile’ command applies a web filtering profile to a firewall policy, controlling access to websites based on URL categories or specific URLs."

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."
