220-1201 Timed Practice Test 2 — 10 Questions

Question 1

A technician is replacing a cracked screen on a smartphone. After removing the old screen, they notice a small, flat, rectangular component with a metal shield is loose near the battery connector. What should they do?

10 minute time limit — choose an answer to begin.

Accepted Answer

Reattach it using double-sided adhesive tape.. The loose component is a battery connector bracket or grounding clip, which is typically secured with adhesive to prevent the battery connector from dislodging. Reattaching it with double-sided adhesive tape restores mechanical stability without soldering, as these parts are not soldered to the motherboard. This ensures reliable power delivery and prevents intermittent shutdowns or charging issues.

Answer

Discard it as it is not needed for the screen replacement.

Answer

Solder it back onto the motherboard.

Answer

Leave it loose; it will not affect screen operation.

Question 2

During a conference call, a user complains that their wireless earbuds keep disconnecting from their smartphone every few minutes. The earbuds work fine when paired with a different phone. What is the most likely cause?

Accepted Answer

Bluetooth interference from other devices in the conference room.. Bluetooth operates in the 2.4 GHz ISM band, which is shared with Wi-Fi, cordless phones, and other wireless devices. In a conference room with many active devices, RF interference can cause packet loss or retransmission delays, leading the Bluetooth Adaptive Frequency Hopping (AFH) mechanism to fail to avoid all congested channels, resulting in periodic disconnections. The fact that the earbuds work fine with a different phone isolates the issue to the smartphone's environment rather than the earbuds themselves.

Answer

The earbuds have a low battery.

Answer

The smartphone's Bluetooth driver is outdated.

Answer

The earbuds are not compatible with the smartphone's Bluetooth version.

Question 3

A technician is setting up a mobile point-of-sale system using a tablet and a portable receipt printer. The printer supports both Bluetooth and NFC. Which connection method should the technician use for reliable, low-latency printing?

Accepted Answer

Bluetooth. Bluetooth is the correct choice because it provides a reliable, low-latency wireless connection specifically designed for peripheral devices like printers. Unlike NFC, which is optimized for very short-range (under 4 cm) tap-to-pair operations and not sustained data streaming, Bluetooth maintains a stable link over distances up to 10 meters and supports the Serial Port Profile (SPP) or Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) for consistent print job throughput.

Answer

NFC

Answer

Infrared

Answer

Wi-Fi Direct

Question 4

A technician is configuring a dual-monitor setup for a stock trader. One monitor is a 24-inch 1080p display, and the other is a 27-inch 4K display. The user wants the mouse to move seamlessly between them. What setting must the technician configure in the OS display settings?

Accepted Answer

Arrange the displays in the OS to match their physical positions.. The OS display arrangement settings (e.g., in Windows Display Settings or macOS Displays) allow the technician to drag and position the virtual representations of the monitors to match their physical placement. This ensures that the cursor moves seamlessly across the bezel edge from one screen to the other, preventing it from getting 'stuck' at an invisible boundary. Without this alignment, the mouse may jump to an unexpected location or fail to cross between displays smoothly.

Answer

Set both monitors to the same resolution.

Answer

Adjust the scaling settings on the 4K monitor.

Answer

Set the 4K monitor as the primary display.

Question 5

A user wants to use a wired headset with their tablet for voice calls, but the tablet only has a single USB-C port and no 3.5mm jack. The headset has a 3.5mm plug. Which accessory should you recommend?

Accepted Answer

A USB-C to 3.5mm adapter.. A USB-C to 3.5mm adapter converts the digital audio signal from the USB-C port into an analog signal that the wired headset can use. This adapter typically includes a built-in DAC (Digital-to-Analog Converter) to handle the conversion, enabling voice calls through the tablet's USB-C port without requiring additional power or Bluetooth pairing.

Answer

A USB-C hub with multiple ports.

Answer

A Bluetooth audio adapter for the headset.

Answer

A 3.5mm Y-splitter cable.

Question 6

A technician is configuring a smartphone for a user who frequently travels internationally. The user wants to avoid high roaming charges but still use data when connected to local Wi-Fi. What should the technician do?

Accepted Answer

Disable cellular data in the mobile network settings.. Disabling cellular data in the mobile network settings prevents the device from using the carrier's mobile data network, thereby avoiding roaming charges. The user can still connect to local Wi-Fi networks for data access, as Wi-Fi operates independently of the cellular data radio. This approach ensures that no data is transmitted over the cellular network while traveling internationally.

Answer

Enable airplane mode and then turn on Wi-Fi.

Answer

Enable data roaming.

Answer

Set the device to 2G only.

Question 7

A technician is setting up internet for a remote cabin that is 5 miles from the nearest road. No wired infrastructure exists. Which connection type is most practical for reliable, moderate-speed internet?

Accepted Answer

Satellite. Satellite internet is the only viable option for a remote cabin 5 miles from the nearest road with no wired infrastructure. It uses a geostationary satellite to provide coverage anywhere with a clear line of sight to the sky, offering moderate speeds (typically 25–100 Mbps) without requiring terrestrial cabling. DSL, cable, and fiber all depend on physical infrastructure (copper phone lines, coaxial cable, or fiber optic cables) that cannot reach such a remote location.

Answer

DSL

Answer

Cable

Answer

Fiber optic

Question 8

A technician is troubleshooting an iPhone that cannot install or update any apps from the App Store. The device is connected to Wi-Fi, and other internet services (Safari, email) work. What should the technician check first?

Accepted Answer

Verify that the Apple ID is signed in and has no payment issues.. The most common cause for an iPhone being unable to install or update apps while other internet services work is an issue with the Apple ID, such as a payment method that has expired or a billing problem. The App Store requires a valid payment method on file even for free apps, and the device will block downloads until the account is resolved. Since Safari and email function normally, the network connectivity is fine, narrowing the issue to account authentication or authorization.

Answer

Check if the date and time are set correctly on the iPhone.

Answer

Reset the iPhone's network settings.

Answer

Check if the iPhone is in Low Power Mode.

Question 9

A customer reports that their internet connection drops frequently during rainstorms. They have a cable modem and a wireless router. What is the most likely cause of the intermittent connection?

Accepted Answer

The cable modem's coaxial cable connection is compromised by moisture.. Cable internet relies on a coaxial cable connection from the street to the modem. During rainstorms, moisture can seep into damaged or poorly sealed coaxial connectors or cable sheathing, causing signal attenuation or intermittent shorting that drops the connection. This is a classic symptom of RF signal degradation due to water ingress, which directly affects the physical layer (Layer 1) of the cable modem's link.

Answer

The wireless router is overheating.

Answer

The DSL filter is malfunctioning.

Answer

The satellite dish is out of alignment.

Question 10

A technician is tasked with upgrading the RAM in an all-in-one (AIO) desktop. The AIO has a sealed back cover with several screws. After removing the screws, the cover still does not come off. What should the technician do next?

Accepted Answer

Use a plastic spudger to gently pry the cover along the seam to release clips.. All-in-one (AIO) desktops often use plastic clips along the seam in addition to screws to secure the back cover. After removing all visible screws, a plastic spudger is the proper tool to gently release these clips without damaging the casing or internal components. Forceful prying with metal tools or applying heat can crack the plastic or damage the display panel.

Answer

Use a flathead screwdriver to pry the cover off forcefully.

Answer

Check if there are hidden screws under rubber feet or stickers.

Answer

Apply heat to the back cover to soften any adhesive.
