Unit 4: Network Operations
Networking · Unit 4 · Paper 1

Network Operations 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.

Each paper is built from this unit’s 40 terms and is the same for everyone, so a teacher can assign “Unit 4, 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 user reports that a website will not load. Testing shows the user can successfully ping 8.8.8.8 but receives an error when pinging the site by its domain name.

Identify the most likely cause of the problem and justify your identification.

Explain what the successful ping to 8.8.8.8 rules out.

List, in order, four commands or tools you would use to isolate the fault, stating what each would tell you.

Describe the steps of a structured troubleshooting methodology.

Explain why changes made during troubleshooting should be documented.

Explain what a network baseline is and why having one makes troubleshooting faster.
