AZ-900 Describe Azure management and governance Practice Question
Which Azure tool helps organizations evaluate and quantify the potential impact of Azure service disruptions on their operations?
⚠ Common exam trap
Many exam-takers confuse proactive monitoring (Azure Monitor Alerts) with post-incident analysis (Azure Service Health reports), or they mistakenly think Application Insights covers Azure infrastructure failures rather than just application telemetry.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Service Health (post-incident reports)
Azure Service Health provides post-incident reports (Root Cause Analyses or RCAs) that detail the impact of Azure service disruptions, including affected services, regions, and timelines. This allows organizations to quantify downtime and assess operational impact, which is the specific need described in the question.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure Monitor Alerts
Why it's wrong here
Azure Monitor Alerts are reactive threshold evaluations on metrics or log queries, generating notifications (email, SMS, ITSM) when conditions are met (e.g., CPU > 90%). Alerts do not automatically produce a Root Cause Analysis or a narrative post-incident summary; they only indicate that a symptom occurred. Additionally, to assess a platform-level disruption, you would need to configure metric thresholds manually, whereas Service Health already tracks platform incidents for you.
- ✓
Azure Service Health (post-incident reports)
Why this is correct
Azure Service Health provides personalized alerts and the Service Health portal, which includes post-incident Root Cause Analysis (RCA) reports and incident timelines for actual Azure platform outages. These reports detail what happened, when, the impacted regions/services, and the corrective actions taken, making them the correct source for assessing operational impact of an Azure disruption. It surfaces both active issues and completed advisory/incident reports, so after resolution you can review the RCA.
- ✗
Azure Application Insights failure analysis
Why it's wrong here
Azure Application Insights failure analysis is an Application Performance Management (APM) feature that dissects exceptions, failed dependencies, and server-side request failures within your own application telemetry. It is scoped to application code and dependencies, not the health of Azure platform services themselves. Therefore it cannot yield post-incident root-cause reports for an Azure infrastructure disruption that affects multiple customers.
- ✗
Azure Advisor reliability recommendations
Why it's wrong here
Azure Advisor reliability recommendations are proactive, curated best practices that flag configuration changes to improve resiliency (e.g., geo-redundant storage, backup enablement) before failures occur. They do not provide retrospective analysis of a specific outage or platform incident. Assessing the operational impact of a completed Azure disruption requires incident-specific reporting, which Advisor does not offer.
