In Distributed Traces, how is the trace-id propagated in an environment?

In distributed tracing, Dynatrace follows standard tracing protocols (such as W3C Trace Context), where the trace ID is propagated via HTTP headers between services.

This enables:

End-to-end trace continuity across services

Correlation of requests across distributed systems

Seamless tracking through microservices architectures

The trace context is typically included in headers like traceparent, ensuring each downstream service continues the same trace.

Other options are incorrect because:

XML and JSON payloads are not used for trace propagation

TLS handshake is unrelated to trace context propagation
