hard📝 Conceptual Q10 of 15
Step-by-Step Solution
Solution:
Step 1: Understand asynchronous messaging impact on tracing
Async calls do not follow direct request-response, so trace context must be passed explicitly to link spans.Step 2: Evaluate options
Because asynchronous calls break the direct request-response chain, requiring explicit context passing correctly explains the need for context propagation; others are incorrect or unrelated.Final Answer:
Because asynchronous calls break the direct request-response chain, requiring explicit context passing -> Option DQuick Check:
Async tracing needs context propagation [OK]
Quick Trick: Async calls need explicit trace context passing [OK]
Common Mistakes:
MISTAKES- Assuming async systems auto-generate trace data
- Thinking synchronous calls don't need tracing
- Believing context propagation reduces latency
