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

Accepted Answer

The tablet is using the wrong Bluetooth profile or driver for the printer.. The most likely cause is that the tablet is using the wrong Bluetooth profile or driver for the printer. Bluetooth printers typically use the Serial Port Profile (SPP) or Hardcopy Cable Replacement Profile (HCRP) to receive print data. If the tablet's POS app or Bluetooth stack is sending data using a different profile (e.g., A2DP for audio or HID for input), the printer will receive garbled or uninterpretable data, even though the devices are paired.

Answer

The printer is out of paper.

Answer

The Bluetooth signal is weak.

Answer

The printer's battery is low.

Question 2

A user is trying to connect their smartphone to a car's infotainment system using Bluetooth for hands-free calling. The phone pairs successfully, but audio only plays through the phone's speaker, not the car's speakers. Which of the following is the most likely reason for this issue?

Accepted Answer

The phone is only connected for phone calls (HFP) and not for media audio (A2DP).. The phone pairs successfully but only plays call audio through the phone speaker, which indicates a profile mismatch. Bluetooth Hands-Free Profile (HFP) handles phone call audio, while Advanced Audio Distribution Profile (A2DP) is required for streaming media audio to the car speakers. If the phone is connected only for HFP (often the default for call-only connections), media audio will not route to the car, even though pairing succeeded.

Answer

The car's Bluetooth system does not support the phone's Bluetooth version.

Answer

The car's speakers are defective.

Answer

The phone's audio output is set to 'Speaker' in the call app.

Question 3

A technician is installing a new network printer in a corporate environment. The printer supports both USB and Ethernet connectivity. The office requires that all users on the same subnet be able to print without needing a dedicated print server. What configuration method should the technician use?

Accepted Answer

Configure the printer with a static IP address and connect it to the network switch via Ethernet.. To allow all users on a subnet to print without a dedicated server, the printer should be configured with a static IP address and connected via Ethernet. This makes it a network printer accessible by IP. USB connection would only allow local printing from one computer.

Answer

Connect the printer via USB to a user's computer and share it from that computer.

Answer

Use a crossover cable to connect the printer directly to a user's computer.

Answer

Set up a Bluetooth connection for the printer.

Question 4

A user wants to connect their laptop to a 4K external monitor for a presentation. The laptop has USB-C ports, and the monitor supports HDMI and DisplayPort. Which adapter or cable should the technician recommend for the best video quality?

Accepted Answer

USB-C to DisplayPort cable. A USB-C to DisplayPort cable supports native DisplayPort Alt Mode over USB-C, which can deliver uncompressed 4K video at 60Hz or higher without conversion. This provides the best video quality for a 4K external monitor, as DisplayPort is designed for high-bandwidth video and supports higher refresh rates and color depths than HDMI in many implementations.

Answer

USB-C to VGA adapter

Answer

USB-C to HDMI adapter

Answer

USB-C to DVI adapter

Question 5

A technician is deploying a fleet of tablets for field workers who need to print invoices on a Bluetooth printer. The tablets are Android-based and support Bluetooth 5.0. The printer is an older model supporting Bluetooth 2.1. Which of the following is true about the compatibility between these devices?

Accepted Answer

The tablet and printer will connect but only at Bluetooth 2.1 capabilities.. Bluetooth is backward compatible, meaning a Bluetooth 5.0 device can connect to a Bluetooth 2.1 device. When paired, the connection negotiates the highest common version, which is Bluetooth 2.1. Therefore, the tablet and printer will connect but only at Bluetooth 2.1 capabilities, including its speed, range, and power consumption profile.

Answer

The tablet will not be able to pair with the printer due to version mismatch.

Answer

The connection will operate at Bluetooth 5.0 speeds and range.

Answer

The printer must be upgraded to Bluetooth 4.0 to work with the tablet.

Question 6

A customer wants to use a portable projector with their smartphone for impromptu presentations. The smartphone has a USB-C port that supports DisplayPort Alt Mode. Which accessory will enable this connection?

Accepted Answer

A USB-C to HDMI adapter. The smartphone's USB-C port supports DisplayPort Alt Mode, which allows it to output a video signal over the USB-C connection. A USB-C to HDMI adapter converts this native DisplayPort signal into HDMI, enabling the portable projector to receive the video input. This is the standard accessory for connecting a USB-C device with DisplayPort Alt Mode to an HDMI display.

Answer

A USB-C to USB-A adapter

Answer

A Bluetooth audio receiver

Answer

A wireless HDMI dongle

Question 7

A company uses a custom Android app that stores data locally. After a recent OS update, the app fails to write data to the internal storage, but it can read existing data. The app has all necessary permissions. What is the most likely cause?

Accepted Answer

The OS update introduced scoped storage restrictions that the app does not support.. This question tests advanced knowledge of Android storage changes. Starting with Android 11, scoped storage restrictions limit how apps access shared storage. Even with permissions, apps may need to use specific APIs (like MediaStore or SAF) to write files. The app likely needs an update to comply with the new storage model.

Answer

The internal storage is full and cannot accept new data.

Answer

The app's cache needs to be cleared to free up space.

Answer

The device's SD card has been removed.

Question 8

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. The dock supports 60W power delivery, but the laptop requires 65W. When the power provided is less than the laptop's demand, the laptop will draw power from both the dock and its internal battery to meet the shortfall, causing the battery to drain even while connected. This is a classic case of insufficient power delivery from the dock, not a battery failure or cable issue.

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 9

A user's Android phone is running slowly and frequently shows 'App not responding' messages. The user has not installed any new apps recently. What should a technician do first?

Accepted Answer

Check for available OS and app updates.. This scenario requires systematic troubleshooting. Checking for OS and app updates is a safe, non-destructive first step, as updates often fix performance bugs. Clearing cache is also valid but less likely to address underlying issues.

Answer

Perform a factory reset.

Answer

Uninstall all recently used apps.

Answer

Replace the phone's battery.

Question 10

A user connects a USB-C docking station to their laptop and finds that the external monitor works, but the Ethernet port on the dock does not provide network connectivity. The laptop's built-in Wi-Fi works fine. Which is the most likely cause?

Accepted Answer

The docking station's Ethernet driver is not installed. USB-C docking stations often require specific drivers for their integrated Ethernet adapters to function. Since the external monitor works, the USB-C connection itself is functional, isolating the issue to the Ethernet component. The missing driver prevents the OS from recognizing the network interface, even though the dock's other features operate normally.

Answer

The Ethernet cable is faulty

Answer

The USB-C port on the laptop is damaged

Answer

The laptop's Wi-Fi is interfering with Ethernet

Question 11

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 is the correct choice because it provides sufficient bandwidth (up to 40 Gbps) to drive two 4K monitors simultaneously, includes a dedicated Ethernet port for wired networking, and delivers power delivery (PD) to charge the laptop—all through a single USB-C connection that is backward-compatible with Thunderbolt 3.

Answer

A USB-C to dual HDMI adapter

Answer

A USB 3.0 hub with HDMI and Ethernet

Answer

A KVM switch

Question 12

A technician is deploying tablets for use in a warehouse where workers wear gloves. The tablets need to be used for scanning barcodes and entering data. Which accessory is most critical for this environment?

Accepted Answer

A rugged case.. In a warehouse environment where workers wear gloves, the most critical accessory is a rugged case because it protects the tablet from drops, dust, and moisture common in industrial settings. While gloves prevent capacitive touchscreen use, a rugged case does not solve input issues but ensures device survival; however, the question asks for the most critical accessory for the environment, and without rugged protection, the tablet would fail quickly. The correct answer is C because it directly addresses the physical hazards of the warehouse, which are more fundamental than input method challenges.

Answer

A screen protector.

Answer

A Bluetooth keyboard.

Answer

A capacitive stylus.

Question 13

A marketing team uses tablets to capture customer signatures on glass screen protectors. They report that the capacitive stylus often skips or fails to register strokes near the edges of the screen. After testing, you find the issue persists even without the protector. Which accessory should you recommend to improve stylus precision?

Accepted Answer

A fine-tip active stylus. The issue persists without the screen protector, ruling out the protector as the cause. A fine-tip active stylus (Option C) uses a digitizer and Bluetooth or proprietary protocol to communicate with the tablet, providing precise edge-to-edge tracking. Passive capacitive styluses rely on the finger's electrical field and often fail near edges due to reduced capacitive coupling, making an active stylus the correct solution.

Answer

A tempered glass screen protector with an oleophobic coating

Answer

A Bluetooth keyboard

Answer

A different passive capacitive stylus with a larger tip

Question 14

A technician is deploying several Android tablets for use as point-of-sale (POS) terminals. The tablets must run a custom POS app in kiosk mode, preventing users from accessing other apps or settings. Which configuration method should the technician use?

Accepted Answer

Use a Mobile Device Management (MDM) solution to configure kiosk mode.. This question tests knowledge of mobile device management (MDM) and kiosk mode deployment. The correct approach is to use an MDM solution to lock the device into a single-app kiosk mode, which is a standard enterprise feature for dedicated devices.

Answer

Enable Developer Options and set the app as the default launcher.

Answer

Install a third-party launcher and hide all other apps.

Answer

Root the tablets and modify the system partition to block other apps.

Question 15

A field technician frequently uses a ruggedized tablet outdoors for data collection. They complain that the screen is hard to read in direct sunlight. Which accessory would best improve screen visibility without adding significant bulk?

Accepted Answer

An anti-glare screen protector. An anti-glare screen protector uses a matte finish with microscopic ridges that diffuse reflected light, reducing glare and improving contrast in bright environments. This directly addresses the technician's issue of poor readability in direct sunlight without adding significant bulk to the ruggedized tablet.

Answer

A privacy filter

Answer

A portable external monitor

Answer

An external battery pack

Question 16

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 17

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. MHL (Mobile High-Definition Link) allows a smartphone to output video and audio through its USB port (often USB-C or micro-USB) and converts it to HDMI, which is exactly what is needed to connect to a TV with only an HDMI port. This adapter is the most appropriate because it directly bridges the smartphone's mobile output to the TV's HDMI input without requiring any wireless network or additional power source.

Answer

A USB-C to USB-A hub

Answer

A Bluetooth speaker

Answer

A wireless display adapter like Chromecast

Question 18

A user reports that their smartphone's mobile hotspot works for a few minutes, then the connected laptop loses internet access, but the smartphone still shows a cellular data connection. The hotspot remains enabled. What is the most likely cause?

Accepted Answer

The carrier is throttling the hotspot data after a usage threshold.. Carrier throttling can reduce data speeds after a certain amount of data is used, making the connection too slow for practical use. This is common on unlimited plans that throttle after a threshold, and the hotspot may still appear active but with severely limited throughput.

Answer

The smartphone's battery saver mode is limiting hotspot performance.

Answer

The laptop's Wi-Fi adapter is overheating.

Answer

The smartphone is switching to a different cellular band.

Question 19

A customer reports that their smartphone connects to Wi-Fi at home but cannot connect to the corporate Wi-Fi network at their office. The office uses WPA2-Enterprise with 802.1X authentication. What is the most likely reason for the connectivity failure?

Accepted Answer

The phone does not have the correct 802.1X credentials configured for the corporate SSID.. The corporate network uses WPA2-Enterprise with 802.1X authentication, which requires the smartphone to have the correct 802.1X credentials (e.g., username/password or certificate) configured for that specific SSID. Without these credentials, the phone cannot complete the EAP (Extensible Authentication Protocol) handshake with the RADIUS server, even though it can connect to a home WPA2-Personal network. Option C directly addresses this missing configuration.

Answer

The phone's Wi-Fi antenna is damaged.

Answer

The corporate network requires a different security protocol like WEP.

Answer

The phone is out of range of the corporate access point.

Question 20

A technician is troubleshooting a smartphone that cannot connect to any Wi-Fi network. The technician has already verified that the device's Wi-Fi adapter is enabled and that other devices can connect to the same networks. What should the technician check next?

Accepted Answer

Check if the device has a static IP address configured.. A static IP address can prevent a device from obtaining a valid IP from the DHCP server, causing connection failure. This is a common issue when a device has been manually configured with an IP that is not in the network's range or is already in use.

Answer

Check the device's MAC address filter on the router.

Answer

Check if the device's date and time are correct.

Answer

Check if the device's Bluetooth is interfering.
