A company needs pages to reach the right on-call engineer based on incident severity, with escalation when nobody acknowledges. Which service should they configure?
Show answer and explanation
Answer: B
Incident Manager uses contacts, escalation plans and response plans to decide who is paged for a given severity and what happens when an engagement is not acknowledged. It integrates with CloudWatch alarms and EventBridge so incidents open automatically and the timeline is captured for review.
A plain notification topic broadcasts messages but has no concept of severity, ownership or escalation.
Why the other options are wrong
- A. SNS delivers messages to subscribers. It provides no on-call schedule, acknowledgement tracking or escalation path.
- C. EventBridge routes events to targets. Routing rules alone do not page a person or escalate an unacknowledged alert.
- D. Trusted Advisor reports best-practice checks. It is not an alerting or escalation service.
