JN0-102 · Question #12
A user opens a webpage that requires the transmission of packets from the Web server to the client's browser. The packets transmitted from the Web server to the client exceed the smallest MTU value…
The correct answer is A. packet segmentation C. packet sequencing. When packets exceed the Path MTU, the transport layer employs packet segmentation to break the large data into smaller pieces, and packet sequencing to reassemble these pieces correctly at the destination. These functions ensure reliable delivery despite size constraints.

Why each option
When packets exceed the Path MTU, the transport layer employs packet segmentation to break the large data into smaller pieces, and packet sequencing to reassemble these pieces correctly at the destination. These functions ensure reliable delivery despite size constraints.
Packet segmentation (or fragmentation) is the process of breaking larger packets into smaller units that conform to the Maximum Transmission Unit (MTU) of the network links. This allows data to traverse links with smaller MTUs.
Serialized checking is not a standard protocol function related to packet size or reassembly; checksums are used for error detection.
Packet sequencing involves numbering the segments so that the receiving host can reassemble them in the correct order, ensuring the integrity of the original data despite being broken into multiple packets.
Parallel checking is not a standard protocol function related to packet size or reassembly; checksums are used for error detection, typically not in parallel.
