The answer is a corrupted Wi-Fi profile on the iPhone. After basic troubleshooting like rebooting the phone and router fails, the most likely culprit is a damaged or misconfigured network profile stored on the device. This profile contains authentication keys and connection settings; when corrupted, it causes the phone to repeatedly drop and re-establish the connection, even when the network itself is stable. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of common mobile device connectivity issues and the appropriate escalation path beyond power cycles. A common trap is assuming the router is faulty or that the issue is hardware-related, but the exam emphasizes software-level fixes first. The correct solution is to forget the network and re-enter the password, which forces the phone to create a fresh profile. Memory tip: “Forget to fix” — if rebooting fails, forget the network to clear the corrupted profile.
220-1102 Mobile OS and App Troubleshooting Practice Question
This 220-1202 practice question tests your understanding of mobile os and app troubleshooting. 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 complains that their iPhone's Wi-Fi keeps disconnecting and reconnecting. They have already rebooted the phone and the router. Which of the following is the MOST likely cause?
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.
Why wrong: A faulty SIM card affects cellular service, not Wi-Fi connectivity.
B
The Wi-Fi network password was changed recently.
Why wrong: While a changed password can cause disconnection, the symptom of repeated disconnects suggests a different issue, as the phone would simply fail to connect.
C
The phone's Wi-Fi profile is corrupted.
A corrupted Wi-Fi profile can cause intermittent disconnects; forgetting the network and reconnecting often fixes this.
D
The phone's operating system needs a full restore via iTunes.
Why wrong: A full restore is excessive for a Wi-Fi issue; simpler steps like forgetting the network should be attempted first.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 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.
