220-1201 Practice Question: A technician is setting up a new tablet for a…
A technician is setting up a new tablet for a field worker who needs to capture signatures from customers. The tablet has a standard USB-C port. Which accessory is most appropriate for this task?
⚠ Common exam trap
The CompTIA A+ exam often tests the distinction between passive capacitive styluses (which work on any capacitive touchscreen) and active styluses (which require a digitizer), leading candidates to incorrectly assume a fine-tip stylus is only for resistive screens or that a Bluetooth keyboard could be used for signature input.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A capacitive stylus with a fine tip.
A capacitive stylus with a fine tip (Option B) is the most appropriate accessory because it allows the field worker to accurately capture signatures on the tablet's touchscreen. Capacitive styluses work by mimicking the electrical properties of a human finger, and a fine tip provides the precision needed for signature capture without relying on a digitizer or active pen protocol.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A Bluetooth keyboard for typing notes.
Why it's wrong here
A Bluetooth keyboard is designed for alphanumeric text entry, providing discrete character input rather than continuous, fluid motion. While excellent for typing notes or documents, it lacks the necessary interface and functionality to capture the intricate, continuous lines and pressure variations inherent in a handwritten signature. Its purpose is entirely different from a drawing or writing input device.
- ✓
A capacitive stylus with a fine tip.
Why this is correct
A capacitive stylus with a fine tip is the ideal tool for signature capture on a tablet. Capacitive screens detect the electrical properties of a finger or a passive stylus, and a fine tip allows for significantly greater precision and control compared to a finger. This enables the technician to accurately reproduce the nuances and details of a handwritten signature, making it suitable for tasks requiring precise digital ink.
- ✗
A USB-C to HDMI adapter for external display.
Why it's wrong here
A USB-C to HDMI adapter serves solely as a video output peripheral, converting the tablet's digital display signal from its USB-C port into an HDMI format for an external monitor or projector. Its function is to extend or mirror the tablet's screen, providing no capability whatsoever for inputting data, capturing signatures, or interacting with the tablet's touch interface. It is a display-centric device.
- ✗
A screen protector to prevent scratches.
Why it's wrong here
A screen protector is a passive accessory primarily designed to safeguard the tablet's display from scratches, cracks, and smudges. While it covers the screen, its function is purely protective and does not inherently enhance or facilitate the process of capturing a signature. It does not provide any active input capabilities or improve the precision of touch input beyond maintaining the screen's integrity.
