- A
A rugged case and a Bluetooth keyboard.
Why wrong: A rugged case protects the tablet, but a keyboard is unnecessary for a POS system; a charging solution is more critical.
- B
A stand and a charging dock.
The stand provides a stable mount, and the charging dock ensures the tablet remains powered all day, which is essential for continuous operation.
- C
A screen protector and a stylus.
Why wrong: A screen protector is nice but not essential, and a stylus is not needed for a POS system.
- D
A portable battery pack and a car charger.
Why wrong: A battery pack could work, but it is less convenient than a fixed charging dock, and a car charger is not suitable for a counter setup.
Question 302 of 1,020
What Accessories Are Needed for a Mobile Point-of-Sale Tablet?
This 220-1201 practice question tests your understanding of mobile device accessories. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Quick Answer
The answer is a stand and a charging dock. These two accessories are essential because a mobile point-of-sale tablet must remain securely mounted on the counter for customer interaction and continuously powered throughout the business day to avoid transaction interruptions. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of peripheral deployment requirements for retail environments, where uptime and physical security are critical. A common trap is selecting a screen protector or Bluetooth keyboard—while useful, they are not essential for basic POS operation, and the keyboard is typically replaced by a touchscreen interface. For memory, think “mount and power”: the stand provides the mount, and the charging dock provides the power, forming the core of any fixed tablet POS setup.
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
A charging dock typically uses pogo pins or a dedicated connector to deliver DC power directly to the tablet's charging circuit, bypassing the USB port for faster and more reliable charging. In a retail environment, the stand often includes cable management to keep the power cable tidy and prevent accidental disconnection, ensuring the tablet remains powered during peak transaction hours.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
