What does the acronym PCI stand for?

• A. A security standard for wireless networks.
• B. A set of recommendations for physical security of data centers.
• C. A brand for payment processing hardware.
• D. Payment Card Industry.

Answer: (D)

The concept tested is understanding what PCI stands for in the context of payment security. PCI stands for Payment Card Industry, the collective group of card brands and the ecosystem involved in processing card payments. The security standard most people refer to in this space is PCI DSS, which is Payment Card Industry Data Security Standard, a specific set of rules developed by the PCI Security Standards Council to protect cardholder data. So, the expansion that matches the acronym in this context is Payment Card Industry. The other options describe topics unrelated to the acronym’s meaning here, such as wireless network standards, data center physical security, or a brand for payment hardware.
