Systems Security Certified Practitioner – SSCP – Question0988

Which of the following statements pertaining to packet switching is incorrect?

A. Most data sent today uses digital signals over network employing packet switching.
B. Messages are divided into packets.
C. All packets from a message travel through the same route.
D. Each network node or point examines each packet for routing.

Correct Answer: C

Explanation:

When using packet switching, messages are broken down into packets. Source and destination address are added to each packet so that when passing through a network node, they can be examined and eventually rerouted through different paths as conditions change. All message packets may travel different paths and not arrive in the same order as sent. Packets need to be collected and reassembled into the original message at destination.
