What's changed: Deepened DOP-C02 Chapter 5 (added comparison tables, scenarios, FAQs, exam traps, deep-dive paragraphs to each section; localized figures to Japanese)
5.3Notification and Escalation
Understand incident notification and operations—SNS, EventBridge, Systems Manager Incident Manager, Chatbot (Slack/Teams), and dead-letter queues (DLQ). Reach the right people reliably and coordinate response.
Beyond detection and remediation, notifying the right people and escalating matters. SNS and Incident Manager coordinate response.
5.3.1Notification and incident management

- Chatbot: relay ops notifications/alarms to Slack/Teams.
- Incident Manager: coordinate escalation plans, response plans, and on-call for major incidents.
- DLQ: park messages that fail delivery/processing for later reprocessing.
