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.

This course has no free-response prompt tagged to this unit, so one from elsewhere in the course is used. It is still worth writing — the skill transfers.

Users on one floor of a building report that internal file shares work normally but no external websites load. (a) Describe a structured troubleshooting methodology and explain why working in a defined order is better than changing settings until something works. (b) Explain what the ability to reach internal resources but not external ones tells you about where the fault is likely to be. (c) Name two commands or tools you would use, and state precisely what each result would rule in or out. (d) You find the floor's switch has a misconfigured VLAN. Explain what a VLAN does and why a misconfiguration could produce exactly this symptom.
