- A
Tone generator and probe
Why wrong: A tone generator and probe are used to trace a specific cable among many, not to test termination quality.
- B
Multimeter
Why wrong: A multimeter can check continuity but is less efficient for testing all eight wires and proper pairing in a twisted-pair cable.
- C
Cable tester
A cable tester is designed specifically to verify wiring continuity, correct pinout, and absence of shorts or opens in network cables.
- D
Loopback plug
Why wrong: A loopback plug is used to test a network port by sending signals back to itself, not to test a standalone cable.

220-1201 Networking Tools Practice Question
This 220-1201 practice question tests your understanding of networking tools. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During a network cable installation, a technician needs to verify that a newly run Cat6 cable is properly terminated and free of shorts or opens. The cable is not yet connected to any switch or device. Which tool should the technician use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cable tester
A cable tester is specifically designed to verify proper termination and detect faults like shorts, opens, or miswires in copper Ethernet cables. Since the cable is not connected to any network device, a cable tester can independently validate the integrity of each wire pair by sending signals and checking continuity, which is exactly what this scenario requires.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse a multimeter's ability to check continuity with the comprehensive wiremap and fault detection that only a cable tester provides, especially when the cable is not yet connected to live equipment.
Detailed technical explanation
How to think about this question
A dedicated cable tester performs wiremap tests that check for continuity, shorts, opens, reversed pairs, split pairs, and crossed pairs by sending a known signal down each conductor and measuring the response at the far end. For Cat6 cables, proper pair twisting and termination are critical to maintain crosstalk performance and meet TIA/EIA-568 standards; a basic continuity test with a multimeter would miss split pairs, which can cause excessive near-end crosstalk (NEXT) even though continuity appears fine.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
