- A
The accelerometer sensor is damaged.
Why wrong: Incorrect. A damaged sensor would cause issues in all apps, not just after an update.
- B
The app being used does not support landscape mode.
Why wrong: Incorrect. The user says the screen won't rotate at all, not just in one app.
- C
The rotation lock is enabled in the Control Center.
Correct. The rotation lock icon in Control Center overrides the app setting and is often toggled accidentally.
- D
The iOS update corrupted the display driver.
Why wrong: Incorrect. A corrupted display driver would cause visual artifacts, not just rotation failure.

iPad Rotation Lock After iOS Update: Troubleshooting Steps
This 220-1201 practice question tests your understanding of mobile device application support. 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 iPad will not rotate the screen when the device is turned sideways, even though rotation lock is off. The issue started after a recent iOS update. What 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.
Quick Answer
The answer is that the rotation lock is enabled in the Control Center. This is the most likely cause because an iOS update can sometimes reset or alter system-level settings, including the orientation lock toggle found in the Control Center, which overrides any app-specific rotation settings. On the CompTIA A+ Core 1 220-1201 exam, this question tests your understanding of iOS configuration and common user-reported issues after updates; a frequent trap is assuming the lock is off simply because it appears disabled within an app, when the system-wide Control Center toggle remains active. To remember this, think of the Control Center as the "master switch" for rotation—no matter what an app shows, if that master switch is flipped, the screen stays locked.
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
✓
The rotation lock is enabled in the Control Center.
Option C is correct because the most common cause of screen rotation failure after an iOS update is that the update resets or changes Control Center settings, re-enabling the rotation lock. The user may have rotation lock off in Settings but it can be toggled on in Control Center without their knowledge, as iOS updates can alter Control Center configurations. The accelerometer and display driver are unlikely to be affected by a standard iOS update, and the issue is system-wide, not app-specific.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The 220-1201 exam often tests the misconception that hardware failures are the primary cause of post-update issues, but the trap here is that candidates overlook the simple software toggle in Control Center, assuming the user's statement 'rotation lock is off' refers only to the Settings app, not the Control Center override.
Detailed technical explanation
How to think about this question
The rotation lock in iOS is a system-level setting stored in the device's NVRAM (non-volatile RAM) and can be toggled via the Control Center's orientation lock button, which is a software switch that overrides the accelerometer's orientation data. After an iOS update, the system may reset certain user preferences, including the Control Center layout, potentially re-enabling the rotation lock without the user's awareness. The accelerometer itself uses MEMS (micro-electromechanical systems) technology to detect gravity and orientation, and its data is processed by the iOS motion coprocessor, which is unaffected by standard software updates.
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.
