Which of the following describes merchants in SAQ-B-IP?

The correct description of merchants in SAQ-B-IP is that they are those with IP-connected payment terminals without data storage. This classification is important within the PCI DSS framework since SAQ-B-IP is specifically tailored for merchants that handle card transactions through IP-connected payment terminals, but do not store, process, or transmit cardholder data by other means.

Merchants using IP-connected payment terminals are acknowledged in this quadrant as they have a more simplified framework to comply with PCI DSS requirements, given that they are not retaining sensitive card data. This aligns with the goal of minimizing security risks associated with cardholder data.

The emphasis on not storing data is a key feature of SAQ-B-IP, as the intent is to support businesses that utilize secure payment terminals in a controlled manner. The other options pertain to different systems and practices which either involve data storage or other methods of transaction processing that are not representative of the SAQ-B-IP criteria.
