Which of the following data connectivity options is the BEST to use when both high availability and reliability are required?

WiFi connections are susceptible to interference, signal strength fluctuations, and range limitations, which can impact reliability and availability.

Bluetooth is a very short-range wireless technology with lower bandwidth, unsuitable for general data connectivity requiring high availability and reliability.

Cellular connections can offer mobility and broad coverage but are subject to signal strength variations, network congestion, and coverage gaps, which can affect reliability and availability.

Wired connections, such as Ethernet, provide the highest level of reliability and availability because they offer a dedicated physical path for data transmission that is generally immune to wireless interference, signal degradation, or limited range. This ensures a consistent and stable connection, critical for applications requiring constant uptime and minimal packet loss.
