Explanation

Data analysis falls outside the telemetry protocol stack because protocol stacks define how data is packaged, transmitted, and delivered - not what is done with it afterward. Analysis is a post-collection application concern, handled by separate systems or software once data has arrived at its destination.

The three distractors are all genuine stack layers: the transport layer carries encoded data across a network (e.g., TCP/UDP); the communication layer manages the connection and routing between devices and receivers; and the data encoding layer serializes raw measurements into a transmissible format (e.g., Protocol Buffers, CBOR).

Memory tip: Think of the telemetry stack as a pipeline - encode it, move it, deliver it. Analysis is what you do after the pipeline ends, so it lives outside the stack entirely.
