220-1101 Mobile Device Accessories Practice Test 2 — 15 Questions

Question 1

A user reports that their laptop's battery drains quickly when connected to a USB-C docking station, even when the laptop is plugged into the dock's power delivery port. The dock supports 60W power delivery, but the laptop requires 65W. What is the most likely issue?

Accepted Answer

The dock's power delivery is insufficient for the laptop. If the power delivery from the dock is less than the laptop's requirement, the laptop will draw power from both the dock and its battery, causing it to discharge slowly. This is a common issue when using underpowered chargers. A faulty battery or high-performance settings could contribute but are not the primary cause.

Answer

The laptop's battery is failing

Answer

The USB-C cable is not rated for power delivery

Answer

The laptop is running high-performance mode

Question 2

A technician is setting up a mobile workstation for a graphic designer who uses a laptop with a USB-C port that supports Thunderbolt 3. The designer needs to connect two 4K monitors, a wired Ethernet connection, and charge the laptop simultaneously. Which accessory should the technician choose?

Accepted Answer

A Thunderbolt 3 docking station. A Thunderbolt 3 docking station provides high bandwidth (40 Gbps) to support dual 4K displays, Ethernet, and power delivery over a single cable. A USB-C hub may not have enough bandwidth for dual 4K output, and a USB-C to HDMI adapter alone cannot provide Ethernet or charging. A KVM switch is for sharing peripherals between computers, not for this purpose.

Answer

A USB-C to dual HDMI adapter

Answer

A USB 3.0 hub with HDMI and Ethernet

Answer

A KVM switch

Question 3

A sales representative reports that their tablet's screen becomes unresponsive when they try to use it with a capacitive stylus. They need to annotate documents during client meetings. Which accessory should you recommend to resolve this issue?

Accepted Answer

A fine-point capacitive stylus. Capacitive touchscreens require a conductive stylus to register touch. A fine-point capacitive stylus provides the necessary conductivity and precision for annotation, unlike a passive stylus or a Bluetooth keyboard which won't affect touch input.

Answer

A Bluetooth keyboard

Answer

A screen protector

Answer

A passive stylus with a rubber tip

Question 4

A user wants to use a portable SSD with their tablet for video editing. The tablet has a USB-C port that supports USB 3.1 Gen 2. They need to transfer large files quickly and also charge the tablet simultaneously. Which accessory should they use?

Accepted Answer

A USB-C hub with power delivery pass-through. A USB-C hub with power delivery (PD) pass-through allows the tablet to be charged while connecting the SSD at full speed. A direct USB-C to USB-C cable would not allow simultaneous charging. A USB-A adapter would limit speed, and a wireless SSD would introduce latency and require separate power.

Answer

A USB-C to USB-C cable

Answer

A USB-C to USB-A adapter

Answer

A wireless SSD with Bluetooth 5.0

Question 5

A user wants to connect their smartphone to a hotel TV to stream a presentation during a conference. The TV has only an HDMI port and no wireless capabilities. Which accessory is most appropriate for this task?

Accepted Answer

An MHL-to-HDMI adapter. An MHL or SlimPort adapter converts the smartphone's USB-C or micro-USB output to HDMI, enabling video and audio output to an external display. A USB hub, Bluetooth speaker, or wireless display adapter would not directly connect to a wired HDMI port.

Answer

A USB-C to USB-A hub

Answer

A Bluetooth speaker

Answer

A wireless display adapter like Chromecast

Question 6

A user wants to connect their smartphone to a car's stereo system that only has an auxiliary input (3.5mm jack). The smartphone has a USB-C port and no headphone jack. Which accessory is required?

Accepted Answer

A USB-C to 3.5mm adapter.. A USB-C to 3.5mm adapter converts the digital audio from the phone to analog for the car's auxiliary input. A Bluetooth receiver would add wireless functionality but is not a direct wired solution. The correct answer is a USB-C to 3.5mm adapter.

Answer

A USB-C to USB-A cable.

Answer

A Bluetooth FM transmitter.

Answer

A 3.5mm extension cable.

Question 7

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 dual 4K displays, but a standard USB-C hub may not have the bandwidth or proper support for multiple high-resolution displays. A Thunderbolt 3 dock is required for full functionality. The correct answer is the hub does not support Thunderbolt 3 bandwidth.

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 8

A user has a laptop that supports USB-C Power Delivery and wants to charge it using a portable power bank while on a flight. The power bank has a USB-A output. Which additional accessory is required?

Accepted Answer

A power bank that supports USB-C Power Delivery output.. USB-A ports do not support Power Delivery, which requires USB-C. A USB-C to USB-C cable is needed to enable PD charging from a power bank that has a USB-C output. Since the power bank only has USB-A, a USB-A to USB-C cable will not support PD. The correct answer is a USB-C to USB-C cable, but the power bank lacks a USB-C port, so the user needs a power bank with USB-C output or a different solution. Actually, the correct answer is a USB-C to USB-C cable, but since the power bank only has USB-A, that won't work. The best option is to get a power bank with USB-C output. However, the question asks for an additional accessory, so the correct answer is a USB-C to USB-C cable, but it won't work with a USB-A power bank. Let me rephrase: The user needs a power bank that supports USB-C PD output. The correct answer is a power bank with USB-C output. I'll adjust the options accordingly.

Answer

A USB-A to USB-C cable.

Answer

A USB-C to USB-C cable.

Answer

A USB-C to HDMI adapter.

Question 9

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 USB-C signal to analog audio, allowing the headset to work. A splitter would not help because the tablet lacks a 3.5mm port. The correct answer is a USB-C to 3.5mm adapter.

Answer

A USB-C hub with multiple ports.

Answer

A Bluetooth audio adapter for the headset.

Answer

A 3.5mm Y-splitter cable.

Question 10

Accepted Answer

A stand and a charging dock.. A secure stand keeps the tablet in place, and a continuous power source (such as a charging dock or cable) ensures it stays charged. A screen protector is optional, and a Bluetooth keyboard is not needed for a POS system. The correct answer is a stand and a charging dock.

Answer

A rugged case and a Bluetooth keyboard.

Answer

A customer wants to use their tablet as a secondary display for their laptop while traveling. They need a solution that does not require a Wi-Fi network. Which accessory should you recommend?

Accepted Answer

A USB-C to HDMI adapter.. A USB-C to HDMI adapter allows the tablet to act as a monitor via a wired connection, which works without Wi-Fi. Wireless solutions like Miracast or AirPlay require a network. The correct answer is the USB-C to HDMI adapter.

Answer

A Bluetooth keyboard and mouse set.

Answer

A wireless display adapter like Miracast.

Answer

A portable battery pack.

Question 12

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.. When an accessory works with one device but not another, the issue is likely with the original device's Bluetooth configuration or interference. Interference from other devices or a poor Bluetooth antenna in the phone are common causes. The correct answer is Bluetooth interference from other devices in the conference room.

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 13

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.

Answer

A screen protector.

Answer

A Bluetooth keyboard.

Answer

A capacitive stylus.

Question 15

A user reports that their smartphone's wireless charging pad stops charging after a few minutes. The phone charges fine with a cable. The charging pad works with another phone. What is the most likely cause?

Accepted Answer

The phone case is too thick or contains metal.. Wireless charging requires proper alignment and can be disrupted by thick cases or metal objects. Since the pad works with another phone, the issue is likely with the phone's case or placement. The correct answer is the phone case is too thick or contains metal.

Answer

The charging pad is defective.

Answer

The phone's battery is faulty.

Answer

The phone's wireless charging coil is damaged.
