問題文
A hospital is designing observability for an assistant that will handle 50,000 requests per day across four agent types. The team is deciding what to collect. Which two statements correctly describe the distinct roles of metrics and traces? (Select two.)
選択肢
- Traces record the sequence and timing of the steps within a single request, so they tell you where in the flow a specific request spent time or failed.
- Metrics can replace traces at scale because aggregated numbers contain the same information in compressed form.
- Logs are unnecessary when both metrics and traces are collected.
- Traces should be used for alerting because they contain the most detail.
- Metrics are aggregated numeric series suited to alerting and trend detection — they tell you that something changed and how widely.
