- A
Connect the printer directly to the router using a long Ethernet cable
Why wrong: This is not practical for a conference room and may create tripping hazards; it also bypasses the structured cabling.
- B
Use a tone generator and probe to trace the wall jack to the patch panel
This tool allows the technician to identify which cable in the patch panel corresponds to the wall jack, enabling proper connection.
- C
Assume the jack is functional and connect the printer
Why wrong: Assuming functionality without verification could lead to connectivity issues if the jack is not properly patched.
- D
Use a WiFi adapter for the printer instead
Why wrong: While this could work, the scenario specifies a wired connection, and the technician should first attempt to use the available wired infrastructure.
How to Use a Tone Generator and Probe to Identify Network Wall Jack Connections
This 220-1201 practice question tests your understanding of connectors. 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.
A technician is setting up a new network printer in a conference room. The printer has an RJ45 port for wired networking, but the only available wall jack is labeled with a different room number. The technician needs to connect the printer to the network. What is the best approach?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Quick Answer
The correct approach is to use a tone generator and probe to trace the wall jack back to the patch panel. This is the best method because the wall jack’s label is unreliable—it may be wired to a different network drop than expected. By connecting the tone generator to the wall jack and sweeping the patch panel with the probe, you can audibly identify the exact port, ensuring the printer connects to the correct network segment. On the CompTIA A+ Core 1 220-1201 exam, this question tests your understanding of physical network troubleshooting and cable management, often appearing in scenarios where labels are missing or incorrect. A common trap is assuming the label is accurate or trying to test connectivity with a cable tester alone, which won’t trace the path. Remember the memory tip: “Tone the jack, probe the rack”—always verify the physical link before patching.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use a tone generator and probe to trace the wall jack to the patch panel
The wall jack may be connected to a different network drop. The technician should use a tone generator and probe to identify which port on the patch panel corresponds to that wall jack, ensuring correct connectivity.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
