An IoT solutions architect is designing a system that includes both battery-powered environmental sensors in remote fields and high-definition security cameras at a main facility. Why would a single communication protocol likely be insufficient for this entire solution?
The devices have vastly different power, processing, and bandwidth capabilities, requiring protocols optimized for each use case.
Cloud providers typically only support a limited set of proprietary protocols for their IoT services.
Network gateways can only translate one type of transmission protocol at a time.
Security standards mandate that low-power devices and high-bandwidth devices cannot use the same communication protocol.
The correct answer is that the devices have different capabilities. The battery-powered sensors are resource-constrained (low power, low bandwidth) and would benefit from a lightweight protocol like MQTT or CoAP. The high-definition cameras are not as constrained and require a protocol that can handle high-bandwidth video streams, such as HTTPS. Using a single protocol for both would be inefficient. The other options are incorrect. Network gateways are designed to translate between multiple protocols. Cloud providers support multiple standard protocols, not just proprietary ones. While security is a concern, it does not fundamentally prevent the use of a single protocol across different device types.
