Telemetry is a technology that remotely collects data from physical or virtual devices at high speed, and has a layered protocol stack. Which of the following layers is not included in the telemetry protocol stack?
The telemetry protocol stack is structured as follows:
Communication layer (A): Manages data transmission between the telemetry client (device) and the server.
Transport layer (B): Uses protocols such as gRPC, HTTP/2, or TCP to transmit telemetry data.
Data encoding layer (C): Encodes data using formats like JSON, Protobuf, or XML.
The Data analysis layer (D) is not part of the telemetry protocol stack itself.
Data analysis typically occurs after the data has been collected and received on the server or collector.
Telemetry focuses on data collection, encoding, transport, and transmission, not on analysis.
Therefore, the correct answer is D.
