問題文
An investigation into a conversation from four months ago finds no trace data at all, although telemetry is configured. What should be checked, and what does it imply for the design?
選択肢
- The retention period, because configuring telemetry without a retention decision means investigations beyond the default window are impossible.
- The telemetry destination, because traces older than three months are moved to a different service and have to be queried from that service instead.
- The agent's publish history, because publishing resets the trace store and four months of releases will have cleared the older records.
- Nothing needs to be checked, because traces are inherently short-lived and conversations from months ago simply cannot be investigated.
