Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Context propagation is not correctly implemented
Incomplete traces often occur when context propagation is not implemented correctly, causing spans to be disconnected.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Context propagation is not correctly implemented
Why this is correct
Missing context propagation breaks trace continuity.
- ✗
Span attributes are missing
Why it's wrong here
Missing attributes do not break trace structure.
- ✗
Sampling rate is too high
Why it's wrong here
High sampling rate would capture more, not cause incomplete traces.
- ✗
Jaeger database is full
Why it's wrong here
A full database may cause data loss but not incomplete traces.
