220-1202 Timed Practice Test 2 — 10 Questions

Question 1

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?

Accepted Answer

The phone's Wi-Fi profile is corrupted.. This scenario tests knowledge of common mobile Wi-Fi issues. After basic steps, forgetting and reconnecting to the network often resolves profile corruption or authentication problems.

Answer

The phone's SIM card is faulty.

Answer

The Wi-Fi network password was changed recently.

Answer

The phone's operating system needs a full restore via iTunes.

Question 2

A user reports that their Android phone's screen is unresponsive to touch, but the buttons and notification LED still work. They have already performed a forced restart. What should the technician do NEXT?

Accepted Answer

Boot the phone into Safe Mode to check if the issue persists.. This scenario tests troubleshooting touchscreen issues. Since a forced restart didn't help, booting into Safe Mode can determine if a third-party app is causing the problem.

Answer

Replace the screen assembly.

Answer

Perform a factory reset from the recovery menu.

Answer

Update the phone's firmware using a computer.

Question 3

A customer's iPhone is experiencing frequent app crashes and the device feels warm to the touch. They have not installed any new apps recently. What is the most likely cause?

Accepted Answer

The operating system needs to be updated.. Overheating in mobile devices often leads to performance throttling and app instability. This scenario suggests a resource-intensive background process or a failing battery, but the most common cause of overheating and crashes without new apps is an outdated OS with known bugs. Keeping iOS updated resolves many stability issues.

Answer

The device has a virus or malware.

Answer

The battery is failing and needs replacement.

Answer

Too many apps are running in the background.

Question 4

A user complains that their Android phone's battery drains quickly after installing a new weather app. The phone is warm to the touch even when idle. What should you do to resolve this?

Accepted Answer

Check battery usage in Settings to see which app is consuming power.. Battery drain and overheating after app installation indicate a misbehaving app. The best first step is to check battery usage statistics to identify the culprit, then force stop or uninstall that app. This is a standard Android troubleshooting procedure.

Answer

Replace the battery immediately.

Answer

Perform a factory reset to remove all apps.

Answer

Update the phone's operating system to the latest version.

Question 5

A user reports that their iPad will not rotate the screen when they turn the device sideways. The rotation lock icon appears in the status bar. What is the most likely cause?

Accepted Answer

Rotation lock is enabled in Control Center or via the side switch.. The rotation lock icon indicates the feature is enabled. On an iPad, this can be controlled via the Control Center or a physical switch on the side. The technician should disable rotation lock before any other troubleshooting.

Answer

The accelerometer is faulty.

Answer

The app being used does not support rotation.

Answer

The device needs a software update to fix a rotation bug.

Question 6

A company's Android devices are failing to connect to the corporate email server after a security policy update. The devices show 'Authentication failed' for the email app. What is the most likely cause?

Accepted Answer

The email app's server settings (IMAP/POP/SMTP) are no longer correct.. After a security policy update, authentication failures often stem from outdated or incorrect server settings. The most common change is an updated server address or port. The technician should verify the incoming/outgoing server settings in the email app.

Answer

The devices need a factory reset to clear cached credentials.

Answer

The SIM cards are deactivated.

Answer

The devices are infected with malware that blocks email.

Question 7

A company deploys a custom app via MDM to Android devices. Users report that the app crashes immediately upon launch. The app works fine on the developer's test device. What is the most likely cause?

Accepted Answer

The app requires a specific Android API level that is not present on the deployed devices.. App crashes on deployment often stem from missing dependencies or incompatible API levels. The most common cause is that the target devices are running an older Android version than the app's minimum SDK. The technician should check the app's manifest requirements against the device OS version.

Answer

The MDM profile is corrupt and needs to be re-pushed.

Answer

The devices have insufficient storage space.

Answer

The app is not signed with the correct enterprise certificate.

Question 8

A customer reports that their computer shuts down unexpectedly after a few minutes of use. The system feels hot to the touch, and the fan is running loudly. What is the most appropriate first step for a technician to take to ensure safety while diagnosing the issue?

Accepted Answer

Unplug the computer, let it cool for 30 minutes, then inspect for dust or fan failure.. This question tests knowledge of electrical safety and proper handling of overheated equipment. The correct answer is to unplug the computer to prevent electrical shock or fire, then allow it to cool before inspecting internal components. Attempting to open a hot system or ignoring the heat can lead to injury or further damage.

Answer

Immediately open the case and touch the CPU heatsink to check temperature.

Answer

Spray compressed air into the vents while the system is running to clear dust.

Answer

Replace the power supply unit immediately to fix the overheating.

Question 9

During a network upgrade, a technician needs to run new Ethernet cables through a drop ceiling. The technician notices that some existing cables are resting on the ceiling tiles and are not secured. What safety concern should the technician address?

Accepted Answer

Secure all cables to the ceiling grid using appropriate cable supports.. Unsecured cables on ceiling tiles can cause the tiles to fall, creating a head injury risk and damaging equipment. Cables should be secured to the building structure using J-hooks or cable trays. This also prevents tripping hazards and maintains fire code compliance.

Answer

Leave the cables as they are and run the new cables alongside them.

Answer

Use zip ties to attach the cables to the sprinkler pipes for stability.

Answer

Remove the existing cables and replace them with the new ones.

Question 10

A technician is tasked with decommissioning a server that contains a RAID array of hard drives. The drives are still functional, but the data must be securely erased. What is the most secure method to ensure data cannot be recovered?

Accepted Answer

Use a degausser to erase the magnetic data on the drives.. Degaussing destroys the magnetic field on the platters, making data unrecoverable. Physical destruction is also secure, but degaussing is the most efficient for bulk drives. Simply reformatting or overwriting may leave recoverable data.

Answer

Perform a quick format of each drive.

Answer

Overwrite the drives with zeros using a low-level format.

Answer

Physically destroy the drives with a hammer.
