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.
