Question

Which protocols are commonly supported by IoT Device Gateways?

A) HTTP, FTP, SMTP, POP3
B) Zigbee, CoAP, MQTT, HTTP
C) Algebra, Geometry, Trigonometry, Calculus
D) Java, C++, Python, Ruby

Answer 1

The commonly supported protocols by IoT Device Gateways are Zigbee, CoAP, MQTT, and HTTP.

Step-by-step explanation:

IoT Device Gateways commonly support the following protocols:

• Zigbee
• CoAP
• MQTT
• HTTP

Zigbee is a low-power wireless communication protocol commonly used in IoT networks. CoAP (Constrained Application Protocol) is a lightweight protocol designed for resource-constrained devices. MQTT (Message Queuing Telemetry Transport) is a publish-subscribe protocol used for efficient communication between IoT devices. HTTP (Hypertext Transfer Protocol) is the protocol used for communication over the internet.
