What are three types of connections in an IoT system? (Choose three.)
- connection to power sources
- application protocols designed for IoT
- exclusive networking for IoT systems
- interconnection among cloud computing systems
- wires and circuitry associated with linking IoT components
- OSI Layer 2 and Layer 3 networking connections
Explanation: There are multiple meanings of the word "connection" when describing IoT systems, including (1) devices that must be connected to some source of power, such as batteries or AC/DC power; (2) the fact that all IoT devices have circuitry interconnecting sensors, actuators, and controllers together; and (3) that IoT devices have networking links at Layer 2 and Layer 3 of the OSI model.
The IoT does not need unique and exclusive network or application connections.
