220-1102 Practice Test 36 — 15 Questions

Question 1

A security incident is reported: an employee's company-issued Android phone is displaying persistent pop-up ads, even when no browser is open. The employee admits to side-loading a game from an unknown website. What is the most likely cause and best immediate action?

Accepted Answer

The side-loaded app is adware; boot into safe mode and uninstall it.. The persistent pop-up ads, even without a browser open, indicate adware behavior typical of malicious apps. Since the employee side-loaded a game from an unknown website, the most likely cause is that the side-loaded app contains adware. Booting into safe mode (which disables third-party apps) and uninstalling the suspicious app is the best immediate action because it removes the adware without data loss, unlike a factory reset.

Answer

The phone has a virus; perform a factory reset immediately.

Answer

The browser is infected; clear the browser cache and data.

Answer

The phone's firmware is compromised; reflash the stock ROM.

Question 2

An employee's company-issued Android phone is suddenly displaying pop-up ads even when no browser is open. The employee claims they only downloaded apps from the official Google Play Store. Which of the following is the MOST likely cause?

Accepted Answer

A recently installed app has been granted 'Draw over other apps' permission.. The 'Draw over other apps' permission allows an app to display content on top of other applications, including the home screen and lock screen. This is a common technique used by adware and malicious apps to serve persistent pop-up ads even when no browser is open, as the app can draw its own window outside of the normal app lifecycle. Since the employee only downloaded from Google Play, this permission abuse is the most likely cause, as even Play Store apps can be granted this permission by the user during installation or runtime.

Answer

The phone's firmware is outdated.

Answer

The phone's Wi-Fi network is infected with malware.

Answer

The phone's screen has a hardware defect causing ghost touches.

Question 3

A user's iPad will not rotate the screen when turned sideways, even though the rotation lock is off in the Control Center. The screen remains in portrait mode. What should you check next?

Accepted Answer

Check the physical mute/orientation lock switch on the side of the iPad.. The correct answer is B because many iPad models (particularly older ones like iPad 2 through iPad 4, and some iPad mini models) include a physical switch on the side edge that can be configured to act as a mute/orientation lock toggle. Even if the software rotation lock in Control Center is off, this hardware switch can independently lock the screen orientation, overriding the software setting. Checking this physical switch is the logical next step before attempting more invasive troubleshooting.

Answer

Check if the app has its own orientation lock setting.

Answer

Perform a hard reset of the iPad.

Answer

Update the iPadOS to the latest version.

Question 4

A technician is configuring a kiosk mode on a company-owned Android tablet for customer use. After enabling the dedicated device management app, the tablet still allows users to exit the kiosk app by pressing the home button. Which setting did the technician MOST likely overlook?

Accepted Answer

The 'Lock task mode' or 'Pin app' feature.. The technician enabled the dedicated device management app but did not activate Android's 'Lock task mode' (or 'Pin app' feature). This mode is required to pin the kiosk app to the foreground and block system navigation keys (Home, Recent Apps), preventing users from exiting the app. Without it, the Home button remains functional, allowing escape from the kiosk environment.

Answer

The tablet's screen timeout setting.

Answer

The tablet's Wi-Fi configuration.

Answer

The device's date and time settings.

Question 5

A user reports that their Android phone will not connect to their corporate Wi-Fi network, but other devices connect fine. They have forgotten the network and re-entered the password, but it still fails. What should you check first?

Accepted Answer

Verify the Wi-Fi password is being entered correctly.. Option B is correct because the most common cause of a single device failing to connect after forgetting and re-entering the network is a typo or case-sensitive error in the Wi-Fi password. Since other devices connect fine, the issue is isolated to the phone, and verifying the password is the quickest, least intrusive step before escalating to more complex troubleshooting.

Answer

Check if the router is using MAC address filtering.

Answer

Reset the phone's network settings to default.

Answer

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

Question 6

A user complains that their Android phone's battery drains extremely fast after a recent OS update. They have already tried restarting the device. What is the most likely cause and solution?

Accepted Answer

The device is performing background indexing; wait a day or two.. After a major OS update, Android devices often perform background indexing of files, media, and app data to optimize search and performance. This process is CPU- and I/O-intensive, causing increased battery drain for 24–48 hours. The correct solution is to wait a day or two for indexing to complete, as restarting alone does not stop this background task.

Answer

The update installed a malware app; perform a factory reset.

Answer

The update reset battery optimization settings; re-enable them.

Answer

The battery is failing due to the update; replace the battery.

Question 7

During a corporate device deployment, a technician configures an iPhone for a new employee. The employee later reports that they cannot receive emails on the native Mail app, but can access the webmail interface in Safari. What is the most likely misconfiguration?

Accepted Answer

The incoming mail server settings are incorrect.. The user can access webmail via Safari but cannot receive emails in the native Mail app. This indicates the email account credentials are valid and the network connection is working, but the incoming mail server (POP3/IMAP) settings are misconfigured. Incorrect incoming server hostname, port, or SSL/TLS settings would prevent the Mail app from downloading new messages while leaving webmail unaffected.

Answer

The email account password was entered incorrectly.

Answer

The outgoing mail server (SMTP) settings are wrong.

Answer

The device's date and time are set incorrectly.

Question 8

A user reports that their corporate email app on an Android device is not syncing. They can browse the internet and use other apps normally. The account was working yesterday. What should you check first?

Accepted Answer

Verify the account username and password in the email app.. Option B is correct because the most common cause of a previously working email account suddenly failing to sync is an authentication issue, such as a changed password or expired credentials. Since other internet services work, the network connectivity is fine, so the problem is isolated to the email app's authentication. Verifying the username and password in the app's account settings is the quickest, least disruptive first step before escalating to more drastic measures.

Answer

Perform a factory reset of the device.

Answer

Replace the device's SIM card.

Answer

Reinstall the operating system.

Question 9

A technician is tasked with installing a new hard drive in a server rack. The rack is located in a cramped, dusty storage room with poor lighting. Which safety practice should the technician prioritize before beginning the installation?

Accepted Answer

Wear a dust mask and use a flashlight to improve visibility.. The correct answer is B because the scenario describes a cramped, dusty storage room with poor lighting, which creates two immediate hazards: inhalation of dust particles and reduced visibility. Wearing a dust mask protects the technician's respiratory system from airborne particulates, while using a flashlight ensures they can see clearly to avoid accidental contact with components or cables. These measures directly address the environmental risks before any work begins.

Answer

Use a step stool to reach the server rack safely.

Answer

Remove the server from the rack and place it on the floor for easier access.

Answer

Disconnect all power cables in the rack to eliminate electrical hazards.

Question 10

A small business owner wants to deploy a custom inventory app to five company-owned iPads. The app is not available on the App Store. Which method should you use to install it?

Accepted Answer

Use Apple Configurator to install the app directly.. Apple Configurator allows IT administrators to install enterprise or custom in-house apps directly onto supervised iOS devices without requiring the App Store. Since the app is not available on the App Store and the iPads are company-owned, Apple Configurator provides a supported, secure method for direct installation using a Mac.

Answer

Download the app from a third-party website and open it in Safari.

Answer

Email the app file to each user and have them install it.

Answer

Enable sideloading in Settings and install via iTunes.

Question 11

A technician is replacing a damaged power supply in a desktop PC. After removing the old unit, the technician notices a large capacitor on the motherboard is bulging. What should the technician do to safely handle this situation?

Accepted Answer

Wear insulated gloves and carefully remove the motherboard for replacement.. A bulging capacitor indicates a failed or failing component that can leak electrolyte, cause further damage, or even burst. The safest course is to wear insulated gloves to avoid electric shock or chemical exposure and replace the entire motherboard, as the capacitor cannot be safely repaired in the field. Ignoring it or attempting makeshift fixes risks short circuits, fire, or injury.

Answer

Proceed with installing the new power supply and ignore the bulging capacitor.

Answer

Use a screwdriver to short the capacitor leads to discharge it.

Answer

Apply electrical tape over the bulging capacitor to contain it.

Question 12

A user's iPhone 13 suddenly shows a black screen with a spinning gear icon after an iOS update. The device does not respond to touch or button presses. What is the most likely cause and the correct first step?

Accepted Answer

Force restart the iPhone by pressing and releasing Volume Up, then Volume Down, then holding the Side button until the Apple logo appears.. The black screen with a spinning gear icon after an iOS update indicates the device is stuck in a boot loop or update process, not a hardware failure. A force restart (Volume Up, Volume Down, hold Side button) is the correct first step because it forces the iPhone to reboot without erasing data, often resolving temporary software hangs. This sequence is specific to iPhone 7 and later models, including the iPhone 13, and bypasses unresponsive touch or button inputs.

Answer

The battery is dead; connect to a charger and wait.

Answer

Place the device in DFU mode and restore via Finder.

Answer

The screen is damaged; replace the display assembly.

Question 13

A technician is troubleshooting an Android tablet that cannot connect to a corporate Wi-Fi network. Other devices connect fine. The tablet shows 'Saved, secured' but no IP address. What is the most likely cause?

Accepted Answer

The tablet has a static IP address configured that conflicts with the network.. The tablet shows 'Saved, secured' but has no IP address, indicating it successfully associated and authenticated with the Wi-Fi network but failed to obtain an IP address via DHCP. A static IP configuration that conflicts with the network's DHCP scope or subnet prevents the device from receiving a valid lease, causing the IP assignment failure while other devices using DHCP connect normally.

Answer

The Wi-Fi adapter is faulty.

Answer

The corporate network requires a VPN profile that is missing.

Answer

The tablet's MAC address is blocked by the router.

Question 14

A technician is replacing the thermal paste on a CPU. After cleaning the old paste, the technician accidentally touches the CPU contacts with bare fingers. What is the primary concern?

Accepted Answer

The CPU contacts may become contaminated with oils from the skin.. Touching the CPU contacts with bare fingers transfers natural oils and contaminants from the skin onto the gold-plated contact pads. These oils can cause corrosion over time or create an insulating layer that impedes proper electrical connectivity, leading to intermittent failures or permanent damage. The primary concern is contamination, not ESD, overheating, or physical pressure.

Answer

The CPU may be damaged by electrostatic discharge (ESD).

Answer

The CPU may overheat due to improper thermal paste application.

Answer

The CPU may be physically damaged by the pressure of the touch.

Question 15

During a network upgrade, a technician needs to run new Ethernet cables through a drop ceiling. What is the most important safety precaution to take?

Accepted Answer

Use a non-contact voltage tester to check for live wires.. The most important safety precaution when running cables through a drop ceiling is to use a non-contact voltage tester to check for live wires. Drop ceilings often conceal electrical wiring, and accidentally cutting or damaging a live wire can cause electrocution, fire, or equipment damage. A non-contact voltage tester allows the technician to detect the presence of AC voltage without making physical contact, ensuring the area is safe before handling cables.

Answer

Wear a hard hat to protect against head injuries.

Answer

Ensure the area is well-ventilated.

Answer

Wear anti-static gloves to prevent ESD.
