220-1202 Practice Test 46 — 15 Questions

Question 1

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 2

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 3

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 4

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 5

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 6

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 7

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 8

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 9

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.

Question 10

A user's Android phone is running extremely slowly after installing a new launcher app. They want to revert to the default launcher without losing data. What is the correct procedure?

Accepted Answer

Go to Settings > Apps > Default apps > Home app and select the default launcher.. Option C is correct because Android allows users to change the default home app via Settings > Apps > Default apps > Home app without uninstalling the new launcher or losing any data. This procedure simply reassigns the default launcher to the system's built-in launcher, preserving all installed apps, settings, and user data.

Answer

Uninstall the new launcher app via the Play Store.

Answer

Perform a factory reset from Recovery Mode.

Answer

Clear the cache partition from Recovery Mode.

Question 11

A technician is cleaning the inside of a desktop computer that has accumulated a large amount of dust. What is the safest method to remove the dust?

Accepted Answer

Use compressed air to blow the dust out of the case.. Compressed air is the safest method because it dislodges dust without physical contact, avoiding electrostatic discharge (ESD) or mechanical damage to sensitive components. Unlike other methods, it does not introduce moisture or static buildup, and it can reach tight spaces between heatsinks and circuit boards.

Answer

Use a standard household vacuum cleaner with a brush attachment.

Answer

Use a damp cloth to wipe down the components.

Answer

Use a soft brush to sweep the dust out.

Question 12

During a printer toner replacement, a technician accidentally spills toner powder on the carpet. What is the correct procedure for cleaning up the spill?

Accepted Answer

Use a toner-rated vacuum or a damp cloth to carefully collect the spill.. Option C is correct because toner powder is a fine, electrically charged plastic dust that can be hazardous if inhaled or if it melts into carpet fibers. Using a toner-rated vacuum with a HEPA filter safely captures the particles without dispersing them, or a damp cloth can be used to gently lift the toner without smearing it deeper into the carpet. This procedure follows manufacturer safety guidelines and prevents damage to standard vacuums, which can ignite or spread the toner.

Answer

Use a standard household vacuum cleaner to quickly remove the toner.

Answer

Wipe up the toner with a dry paper towel and dispose of it in the trash.

Answer

Pour water on the spill to dissolve the toner, then mop it up.

Question 13

A technician is troubleshooting a laser printer that is producing smudged prints. The technician needs to remove the toner cartridge to inspect the drum. What safety precaution should be taken?

Accepted Answer

Avoid touching the drum surface and handle the cartridge carefully to prevent toner spills.. Option C is correct because the primary safety precaution when handling a toner cartridge is to avoid touching the drum surface, which is sensitive to light, oils, and scratches, and to handle the cartridge carefully to prevent toner spills. Toner is a fine powder that can be messy and difficult to clean, but it is not a respiratory hazard under normal handling conditions, so a respirator is not required. The high-voltage power supply in a laser printer is typically discharged automatically when the printer is unplugged, and using a vacuum cleaner for toner spills is dangerous because toner can be electrostatically charged and may cause a fire or explosion in a standard vacuum.

Answer

Wear a respirator mask to avoid inhaling toner particles.

Answer

Discharge the high-voltage power supply before touching the drum.

Answer

Use a vacuum cleaner to clean any spilled toner immediately.

Question 14

A technician is installing a new power supply in a desktop computer. After unplugging the system, what should the technician do before touching any internal components?

Accepted Answer

Press and hold the power button for 10 seconds to drain residual charge, then wear an ESD strap.. Option B is correct because pressing and holding the power button for 10 seconds after unplugging the system discharges the remaining charge in the power supply capacitors and other components, reducing the risk of electric shock or damage. Wearing an ESD strap then provides a path to ground for static electricity, protecting sensitive internal components from electrostatic discharge.

Answer

Wear a grounding strap and immediately open the case.

Answer

Spray the interior with compressed air to remove dust before touching anything.

Answer

Remove the CMOS battery first to ensure no power remains.

Question 15

A technician is called to a warehouse where a forklift accidentally struck a rack containing several desktop PCs. The rack is leaning, and one PC has fallen and is sparking. What is the technician's first priority for safety?

Accepted Answer

Evacuate the area and report the incident to the safety officer or call 911.. The immediate priority when a PC is sparking and a rack is unstable is life safety. Evacuating the area and reporting the incident (to a safety officer or by calling 911) ensures no one is exposed to potential electrical fire, arc flash, or structural collapse. Attempting to unplug or extinguish the sparking PC while the rack is leaning could result in electrocution, burns, or being struck by falling equipment.

Answer

Quickly unplug the sparking PC to prevent a fire.

Answer

Use a fire extinguisher on the sparking PC to prevent ignition.

Answer

Stabilize the rack with a nearby pallet to prevent further collapse.
