220-1201 Practice Test 3 — 10 Questions

Question 1

A user complains that their smartphone's battery drains quickly even when idle. You run diagnostics and find the battery health is at 82%. The device is two years old. Which hardware servicing action is most appropriate?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Replace the battery with a new OEM battery.. This question tests battery replacement thresholds. A battery health below 80-85% often indicates significant degradation, causing poor runtime. Replacing the battery restores normal battery life. Software optimization may help but is secondary to hardware replacement.

Answer

Calibrate the battery by fully draining and recharging.

Answer

Update the operating system to the latest version.

Answer

Disable all background apps and notifications.

Question 2

A customer reports that after a recent fall, their smartphone's screen is completely black, but the device still vibrates when calls come in. The technician suspects the display cable is loose. What is the correct sequence of steps to access and reseat the display cable?

Accepted Answer

Remove the back cover, disconnect the battery, then reseat the display cable.. To access the display cable, the technician must first remove the back cover, then the battery (if not integrated), and disconnect the display cable from the motherboard. This sequence ensures safe access without risking a short circuit from a live battery. The display cable is typically a thin ribbon cable near the motherboard.

Answer

Remove the battery first, then the back cover, and reseat the display cable.

Answer

Reseat the display cable by inserting a spudger through the charging port.

Answer

Perform a factory reset to rule out software issues.

Question 3

A technician is configuring a tablet for field workers who need to transfer large files to a central server. The tablet has a USB-C port. Which connection method provides the fastest data transfer speed?

Accepted Answer

USB 3.1 Gen 2 over USB-C. USB 3.1 Gen 2 over USB-C supports a maximum signaling rate of 10 Gbps, which is significantly faster than any wireless or NFC option. For transferring large files to a central server, this wired connection provides the highest throughput and lowest latency, making it the optimal choice for the scenario.

Answer

Bluetooth 5.0

Answer

Wi-Fi 5 (802.11ac)

Answer

NFC

Question 4

A technician is configuring a mobile hotspot on a smartphone to provide internet access to a laptop. The laptop connects to the hotspot's Wi-Fi network but cannot access the internet. The smartphone has a cellular data connection. Which of the following should the technician check first?

Accepted Answer

The smartphone's mobile data is enabled. Mobile hotspots require cellular data to be enabled; if data is off, the hotspot broadcasts a Wi-Fi signal but no internet passes through. This tests basic troubleshooting of hotspot functionality and the dependency on cellular data.

Answer

The laptop's IP address configuration

Answer

The laptop's firewall settings

Answer

The smartphone's Wi-Fi is turned on

Question 5

A technician is troubleshooting a smartphone that cannot establish an NFC connection with a payment terminal. The phone's NFC is enabled, and the screen is unlocked. The payment terminal shows 'No card detected'. Which of the following should the technician check first?

Accepted Answer

The phone's NFC antenna location and alignment with the terminal. NFC requires close proximity and correct orientation; many phones have the NFC antenna located near the top or back. This tests practical knowledge of NFC hardware placement and the need for precise alignment.

Answer

The phone's battery level

Answer

The payment terminal's internet connection

Answer

The phone's default payment app settings

Question 6

A user reports that their laptop's Bluetooth mouse stops working after the laptop wakes from sleep. The mouse works fine after a reboot. The technician suspects a driver issue. Which of the following steps should the technician take to resolve this without disrupting other Bluetooth devices?

Accepted Answer

Disable and re-enable the Bluetooth adapter in Device Manager.. Disabling and re-enabling the Bluetooth adapter in Device Manager resets the Bluetooth stack without a full reboot, often restoring functionality after sleep. This tests advanced troubleshooting of Bluetooth power management issues.

Answer

Uninstall the mouse driver and reboot.

Answer

Change the mouse's Bluetooth pairing to a different channel.

Answer

Update the laptop's BIOS to the latest version.

Question 7

A user reports that their smartphone's screen protector has a large bubble in the center and the edges are lifting. They installed it themselves two days ago. What is the most likely cause of this issue?

Accepted Answer

The user did not properly clean the screen before installation.. Screen protector bubbles and lifting edges are almost always caused by improper installation, such as not cleaning the screen thoroughly or not aligning the protector correctly. Even high-quality protectors will fail if the surface isn't perfectly clean and dust-free. The correct answer is improper installation.

Answer

The screen protector is incompatible with the phone model.

Answer

The phone's screen has a manufacturing defect.

Answer

The screen protector is a tempered glass type, which is prone to bubbles.

Question 8

A user has a laptop that supports Thunderbolt 3 and wants to connect two external 4K monitors at full resolution. They currently have a single USB-C hub that only supports DisplayPort over USB-C. What is the most likely limitation?

Accepted Answer

The hub does not support Thunderbolt 3 bandwidth.. Thunderbolt 3 supports up to 40 Gbps bandwidth, which is required to drive two 4K monitors at full resolution (60 Hz) over a single connection. A standard USB-C hub that only supports DisplayPort over USB-C is limited to USB 3.1 Gen 2 (10 Gbps) or USB 3.2 (20 Gbps) bandwidth, which is insufficient to carry two uncompressed 4K video streams simultaneously. Therefore, the hub itself is the bottleneck because it lacks Thunderbolt 3 controller and bandwidth capabilities.

Answer

The laptop's graphics card cannot drive two 4K monitors.

Answer

The monitors are not compatible with USB-C.

Answer

The user needs a USB-C to HDMI adapter for each monitor.

Question 9

A technician is troubleshooting a tablet that can connect to Bluetooth headphones but cannot connect to a Bluetooth keyboard. The keyboard is known to work with other devices. What should the technician check first?

Accepted Answer

Check if the keyboard is in pairing mode.. The keyboard is known to work with other devices, so the issue is likely that it is not in pairing mode. Bluetooth keyboards require a specific pairing mode (often initiated by holding a key combination) to be discoverable by the tablet. The technician should verify this first before exploring more complex troubleshooting steps.

Answer

Ensure the tablet's Bluetooth is turned on.

Answer

Update the tablet's operating system.

Answer

Reset the tablet's network settings.

Question 10

A small office is setting up a new VoIP phone system. The IT staff must run new cabling to each desk. Which cable type is most appropriate for connecting VoIP phones to the network?

Accepted Answer

Cat5e UTP. Cat5e UTP cable supports 1000BASE-T Ethernet at up to 100 meters, which is sufficient for VoIP phones that typically require 100 Mbps or 1 Gbps connectivity and can also receive Power over Ethernet (PoE) from a switch. This makes it the standard choice for new office cabling for VoIP deployments.

Answer

Coaxial cable

Answer

Fiber optic cable

Answer

Serial cable
