Which of the following statements relating to packet
switching networks is CORRECT?
A. Packets for a given message travel the same route.
B. Passwords cannot be embedded within the packet.
C. Packet lengths are variable and each packet contains the
same amount of information.
D. The cost charged for transmission is based on packet, not
distance or route traveled.
Answer / guest
Answer: D
D is the correct answer since transmission charges are based
on packets transmitted, not the distance or route traveled.
Passwords and other data can be placed within a packet
making choice B incorrect. Choices A and C are not correct
because a complete message is broken into transmission units
(packets), which are routed individually through the network.
