Networking · Unit 1 · Paper 1

Network Foundations unit test

A test on this unit alone, marked as a percentage and a letter grade — for the test your class is actually sitting, rather than for May. Answer everything, then submit once: seeing the answer to question 3 before attempting question 4 makes the final percentage meaningless.

Paper 1 Paper 2 Paper 3

Each paper is built from this unit’s 40 terms and is the same for everyone, so a teacher can assign “Unit 1, Paper 1” and every student sits the identical test. Multiple choice is marked objectively; the written sections you mark yourself against the model answer and rubric.

A file transfer application and a live video call run over the same campus network. (a) State which transport protocol each would typically use and justify each choice in terms of the application's requirements.

(d) Explain why adding TCP's reliability to the video call would likely make the user experience worse, not better.
