In TCP, what does a sequence number do?
A.
Guarantees message delivery
B.
Disassembles and re-assembles packets
C.
Functions as a fault code indicator
D.
Is used in multiplexing
Explanation:
Sequence numbers are populated within packets as a way of ensuring that
the message is delivered to the appropriate destination and is from the appropriate
sender.
A sequence number does not “Guarantee delivery”. It does assist in ensuring the appropriate sequence of packets within a conversation.

This is B. Sequence numbers don’t GUARANTEE delivery. Rather, they help disassemble and reassemble packets in case you get them out of order, or in case some are dropped and you need to wait for retransmission.
