220-1101 Question 13
Single answer1.2 Compare and contrast accessories and connectivity options for mobile devices.A technician is preparing a company-issued Android tablet for a sales employee who needs to give presentations in conference rooms while also using a wireless keyboard during meetings. The tablet has a USB-C port and supports video output over that port. The employee wants the simplest setup with the fewest separate adapters. Which accessory should the technician provide?
- A
A USB-C docking station with HDMI output and USB ports
- B
A Micro-USB to HDMI adapter
- C
A Bluetooth-only display adapter
- D
A Lightning AV adapter
Show answer and explanation
Correct answer: A
Explanation
The best answer is a USB-C docking station with HDMI and USB connectivity because it addresses both needs in one accessory: external display output and connection for input peripherals. On CompTIA A+ Core 1, candidates are expected to compare mobile-device accessories and connectivity options such as USB-C, Lightning, Bluetooth, and display adapters, and choose the most appropriate solution for a real business scenario. USB-C is commonly used for charging, data, and, when supported by the device, video output through alternate modes. A dock or hub is often the most efficient and supportable option because it reduces the number of separate adapters the user must manage. By contrast, Micro-USB and Lightning accessories are connector-specific, and Bluetooth is appropriate for peripherals like keyboards or headsets, not standard room-display video output.
- A. Correct.
Correct. A USB-C docking station or hub that provides HDMI output for the projector/display and USB ports for peripherals is the most practical choice. Since the tablet supports video output over USB-C, a dock can use that single port to connect video and a wired USB receiver or other accessories with minimal extra adapters. This matches a real-world mobile-device accessory scenario covered in A+ Core 1.
- B. Incorrect.
Incorrect. A Micro-USB to HDMI adapter is designed for devices with Micro-USB ports and, in many cases, depends on older standards such as MHL or SlimPort support. The scenario specifically states the tablet has USB-C, so this adapter is not the appropriate fit.
- C. Incorrect.
Incorrect. A Bluetooth-only display adapter is not a standard solution for reliable conference-room video output from a tablet. Wireless display technologies exist, but Bluetooth is not used for normal high-resolution video projection in this context. This option reflects a common misconception that Bluetooth can be used for any wireless accessory, including video output.
- D. Incorrect.
Incorrect. A Lightning AV adapter is intended for Apple devices with Lightning connectors, such as certain iPhones and iPads. It is not compatible with an Android tablet that uses USB-C.
