The correct answer is a soldering iron with a fine tip. This tool is essential because a soldered charging port is physically attached to the main board with solder, meaning you must first desolder the old connections to remove the damaged port and then reflow solder to attach the new one. A fine tip provides the precision needed to heat individual pins without bridging adjacent connections or damaging delicate board traces. On the CompTIA A+ Core 1 220-1201 exam, this question tests your understanding of mobile device hardware repair and the distinction between soldered and modular components. A common trap is choosing a heat gun, but that would risk overheating nearby components like capacitors or the battery connector. Remember the memory tip: “Fine tip for fine pins” — if the port is soldered, you need controlled, pinpoint heat, not a broad blast.
220-1201 Mobile Device Hardware Servicing Practice Question
This 220-1201 practice question tests your understanding of mobile device hardware servicing. 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 customer brings in a smartphone with a broken charging port. They want the port replaced. During disassembly, the technician finds that the charging port is soldered directly to the main board. Which tool is essential for this repair?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A soldering iron with a fine tip.
A soldered charging port requires desoldering to remove it and reflow soldering to install the new one. A soldering iron with a fine tip is necessary for this precision work. Using a heat gun alone could damage nearby components.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
A heat gun with a narrow nozzle.
Why it's wrong here
A heat gun is used for reflowing BGA chips, not for desoldering a small port; it may overheat the board.
✓
A soldering iron with a fine tip.
Why this is correct
A fine-tip soldering iron allows precise desoldering and soldering of the small pins on the charging port.
Related concept
Read the scenario before looking for a memorised answer.
✗
A Phillips-head screwdriver.
Why it's wrong here
A screwdriver is used for screws, not for soldered components.
✗
A plastic spudger.
Why it's wrong here
A spudger is for prying and disconnecting cables, not for soldering.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
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.

Variation 1. A user reports that their smartphone's charging port is loose and the cable falls out easily, making it difficult to charge. The technician inspects the port and sees no visible debris. What is the most likely cause and the appropriate repair?
medium
A.The charging cable is defective; replace the cable.
✓ B.The charging port has worn-out pins; replace the charging port assembly.
C.Use compressed air to blow out the port.
D.Apply a small amount of super glue to the port to tighten it.
Why B: A loose charging port is typically caused by worn or bent internal pins from repeated plugging and unplugging. The correct repair is to replace the charging port assembly, as the pins cannot be individually repaired. Cleaning would not help if the pins are physically damaged.
