Which of the following statements is true regarding this situation?
- AMicrosoft is aware of the issue and is actively working on a resolution.

Show answer & explanationAnswer & explanation
Correct answer: A. Microsoft is aware of the issue and is actively working on a resolution.
A yellow warning icon and a message like 'Performance degradation' in the Service health dashboard indicate that Microsoft has detected a service incident affecting their customers. The 'Monitor for resolution' recommendation confirms that Microsoft is aware and working on it, and the administrator's role is to track progress.
Why the other options are wrong
- B. Service health incidents are about current operational issues, not pending updates which are communicated separately through the Message Center.
- C. Opening a support ticket is typically recommended if the issue is *not* listed in Service Health or if the provided resolution does not apply.
- D. Service health incidents usually indicate widespread issues affecting multiple users or the service as a whole, not just a single user.
Microsoft 365 Service Health Dashboard
A centralized dashboard in the Microsoft 365 admin center that provides real-time information about the status and health of Microsoft 365 services, including incident reports and planned maintenance.
- Communicates service incidents and advisories.
- Provides status updates and estimated resolution times.
- Helps administrators understand service impact and communicate with users.
Memory trick: Service Health is Microsoft's traffic light for their cloud services: Green means go, Yellow means caution (they know!), Red means stop (major issue).
