220-1201 Practice Question: A technician is setting up a mobile point-of-sale…
A technician is setting up a mobile point-of-sale system for a small retail store. The tablet needs to be mounted on the counter and remain powered throughout the day. Which two accessories are essential for this deployment?
⚠ Common exam trap
In the CompTIA A+ 220-1201 exam, candidates often confuse accessories that provide temporary power (like portable battery packs) with those that provide continuous, fixed power (like charging docks), leading them to overlook the 'remain powered throughout the day' requirement.
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 stand and a charging dock.
A stand securely mounts the tablet on the counter at an ergonomic viewing angle, while a charging dock provides continuous power to keep the tablet operational throughout the day without battery depletion. These two accessories directly address the deployment requirements of fixed mounting and uninterrupted power for a stationary point-of-sale system.
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 rugged case and a Bluetooth keyboard.
Why it's wrong here
A rugged case provides valuable physical protection against drops and impacts, which is beneficial for a mobile device in a busy retail environment. However, a Bluetooth keyboard is generally unnecessary for a modern mobile point-of-sale (POS) system, as most transactions are efficiently handled via touchscreen input for item selection, quantity adjustments, and payment processing. More critically, this option fails to address the essential requirement for a continuous and reliable power solution, which is paramount for uninterrupted business operations.
- ✓
A stand and a charging dock.
Why this is correct
A stand is crucial for establishing a stable and ergonomic setup, allowing the tablet to be securely positioned for both staff and customer interaction during transactions. Concurrently, a dedicated charging dock ensures the tablet remains continuously powered throughout extended business hours, preventing unexpected battery depletion that would disrupt sales and customer service. This combination directly addresses the fundamental needs for operational stability and uninterrupted power supply, making it ideal for a reliable counter-based mobile POS system.
- ✗
A screen protector and a stylus.
Why it's wrong here
While a screen protector offers a beneficial layer of defense against scratches and minor screen damage, it is not a fundamental requirement for the core operational functionality of a mobile POS system. Furthermore, a stylus is typically superfluous for point-of-sale applications, as contemporary POS software is optimized for direct finger-based touch input, rendering a stylus an extraneous accessory that adds no significant value to transaction efficiency or user experience. This option also neglects the critical need for a consistent power solution.
- ✗
A portable battery pack and a car charger.
Why it's wrong here
A portable battery pack could offer temporary power, but it requires manual connection and disconnection, making it less convenient and efficient than a dedicated charging dock for a stationary POS setup. More significantly, a car charger is entirely unsuitable for a counter-based mobile POS system, as it relies on a vehicle's 12V DC power outlet, which is unavailable in a typical retail counter environment. This combination fails to provide a practical, continuous, or appropriate power solution for a fixed point-of-sale system.
