問題文
The platform must ensure that a region-wide outage produces one page rather than 200, while still showing which services were affected. Which option correctly identifies the combination of Alertmanager features that does this?
選択肢
- A longer group wait so all the alerts arrive first, plus a longer repeat interval so the notification is not resent.
- Grouping by the alert name and the instance so each instance is visible, plus silences to mute the extra notifications during the outage.
- Grouping by the alert name and the region so the same alert collapses into one notification, plus inhibition so the region-level alert mutes the service-level ones.
- The per-alert-name limit so the extra alerts are dropped, plus deduplication to collapse the remainder into one notification.
