BACnet is ___.

BACnet is ___.

• A. The organization that created building automation network standards
• B. A standards development organization
• C. None of these
• D. A communication standard used in building automation networks

Answer: (D)

BACnet is a communication standard used in building automation networks. It isn’t an organization or a standards-developing body; it’s the protocol that defines how devices such as HVAC controllers, sensors, lighting, and security systems talk to one another across a building. This open standard enables interoperability so equipment from different manufacturers can exchange data using common services and data structures. The other descriptions refer to bodies or concepts that aren’t the actual protocol, so they don’t fit.
