220-1201 Mobile Device Hardware Servicing Practice Question
This 220-1201 practice question tests your understanding of mobile device hardware servicing. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The charging port has worn-out pins; replace the charging port assembly.
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.
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.
✗
The charging cable is defective; replace the cable.
Why it's wrong here
The cable falls out easily, which indicates the port is loose, not the cable. A defective cable would not hold in other devices either.
✓
The charging port has worn-out pins; replace the charging port assembly.
Why this is correct
Worn pins cause a loose connection. Replacing the entire port assembly restores a snug fit and reliable charging.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
Use compressed air to blow out the port.
Why it's wrong here
Compressed air removes debris, but the technician already saw no debris. The issue is physical wear, not dirt.
✗
Apply a small amount of super glue to the port to tighten it.
Why it's wrong here
Glue will permanently damage the port and possibly the cable, and it will not fix the worn pins. This is not a valid repair technique.
