- A
Multimeter
Why wrong: A multimeter can test for continuity but cannot verify the specific pinout required by T568A standards.
- B
Cable tester with wire map
This tool checks each conductor's connection from pin to pin, ensuring the cable is wired correctly per T568A or T568B.
- C
Toner and probe
Why wrong: A toner and probe identifies which cable is which, but does not verify wiring standards or pin assignments.
- D
Crimper
Why wrong: A crimper is used to attach connectors, not to test existing cable wiring.

220-1201 Networking Tools Practice Question
This 220-1201 practice question tests your understanding of networking tools. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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.
A small office has intermittent connectivity issues. The technician needs to verify that the Ethernet cable from the wall jack to the workstation meets T568A wiring standards. Which tool is most appropriate for this task?
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 with wire map
A cable tester with wire map is the correct tool because it verifies that each of the eight wires in the Ethernet cable is terminated to the correct pin on the RJ45 connector according to the T568A standard. This ensures proper continuity and pin-to-pin mapping, which is essential for reliable network connectivity. Intermittent issues often stem from miswired or broken pairs, which a wire map test can detect.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Crimper
Why it's wrong here
A crimper is used to attach connectors, not to test existing cable wiring.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse a toner and probe (used for cable tracing) with a cable tester (used for verifying wiring standards), leading them to choose option C when the question specifically asks for verifying T568A compliance.
Detailed technical explanation
How to think about this question
A cable tester with wire map sends signals down each conductor in sequence and checks that the corresponding pin at the far end lights up in the correct order, ensuring compliance with T568A (e.g., pin 1 = white/green, pin 2 = green, etc.). It can also detect faults like opens, shorts, reversed pairs, and split pairs, which are common causes of intermittent connectivity but are invisible to simple continuity checks. In real-world scenarios, a cable that passes a continuity test may still fail a wire map test due to a split pair, leading to excessive crosstalk and packet loss.
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.
