When connecting two FC switches using FCIP across an IP circuit, which of the following ensures that the FC frames are not segmented?

Link aggregation combines multiple physical links for increased bandwidth and redundancy, but it does not prevent frame segmentation if the frame size exceeds the Maximum Transmission Unit (MTU) of the underlying links.

TCP Offload Engine (TOE) offloads TCP/IP processing to hardware, which can improve network performance, but it does not affect the MTU size or prevent frame segmentation at the network layer.

Jumbo frames are Ethernet frames larger than the standard 1500 byte MTU, typically up to 9000 bytes. Configuring jumbo frames on the IP network infrastructure carrying the FCIP tunnel allows the encapsulated FC frames to be transmitted without fragmentation, thus preserving the integrity and original size of the FC frames.

Dedicated links provide exclusive network paths, which can improve performance and reduce latency, but they do not inherently change the MTU of the network or prevent fragmentation of large frames.
