Which of the following is a disadvantage of USB connections?

The correct answer highlights a key limitation of USB connections—the maximum cable length of 5 meters (approximately 16 feet) for most USB standards, particularly USB 2.0. This limitation can pose challenges in setups where devices need to be placed further away from the computer or power source, requiring the use of additional equipment like USB extenders or hubs to work around the distance issue.

While other options describe aspects related to USB connections, they do not accurately reflect inherent disadvantages. For instance, USB can support multiple devices through the use of hubs, enabling multiple peripherals to connect to a single port. Furthermore, modern USB devices are designed to be energy-efficient, meaning that they typically do not have higher power consumption compared to other connection types. Lastly, USB devices usually employ plug-and-play technology, allowing them to connect and be ready for use without needing manual configuration for each connection. This makes USB connections user-friendly and convenient in most situations.
