AZ-400 Monitoring and Feedback 3 — Questions and Answers
Question 1: What is the retention period for data in a Log Analytics workspace by default, and what is the maximum chargeable retention?
- 7 days default, 90 days max
- 30 days default, 730 days max (Correct answer)
- 90 days default, 2 years max
- 14 days default, 365 days max
Correct answer: 30 days default, 730 days max
Log Analytics workspaces retain data for 30 days by default, and you can extend retention up to 730 days (2 years) at an additional cost.
Question 2: Which Azure service integrates with Azure DevOps to provide work item creation automatically from Application Insights alert failures?
- Azure Service Bus
- Azure Logic Apps
- Azure DevOps work item integration in Application Insights (Correct answer)
- Azure Automation
Correct answer: Azure DevOps work item integration in Application Insights
Application Insights has native Azure DevOps work item integration that can automatically create work items when specific alert conditions are met.
Question 3: In Azure DevOps, which analytics view allows teams to track cumulative flow and identify bottlenecks in their work pipeline?
- Velocity chart
- Cumulative Flow Diagram (Correct answer)
- Burndown chart
- Lead time distribution
Correct answer: Cumulative Flow Diagram
The Cumulative Flow Diagram (CFD) shows the count of work items in each state over time, helping teams spot bottlenecks and flow inefficiencies.
Question 4: What is the role of 'Action Groups' in Azure Monitor?
- Define which metrics to collect
- Group alert rules by severity
- Define who is notified and what actions occur when an alert fires (Correct answer)
- Schedule maintenance windows
Correct answer: Define who is notified and what actions occur when an alert fires
Action Groups define the set of notification recipients and automated actions (email, SMS, webhook, runbook, etc.) triggered when an alert fires.
Question 5: A pipeline fails intermittently and you need to correlate build logs with application errors in the same timeline. Which tool best supports this cross-source correlation?
- Azure Boards
- Azure Monitor Workbooks with Log Analytics (Correct answer)
- Azure Test Plans
- Azure Artifacts
Correct answer: Azure Monitor Workbooks with Log Analytics
Azure Monitor Workbooks can pull data from multiple Log Analytics queries and present them in a unified time-correlated view.
Question 6: Which metric in Application Insights represents the time from when a browser begins loading a page to when the page is fully interactive?
- Server response time
- Page load time (Correct answer)
- Dependency duration
- Request rate
Correct answer: Page load time
Page load time measures the end-to-end duration from navigation start to the page's load event, reflecting the real-user browser experience.
Question 7: When configuring an alert rule in Azure Monitor, what does the 'evaluation frequency' setting control?
- How long data is retained before evaluation
- How often the alert condition is checked against incoming data (Correct answer)
- The number of thresholds evaluated per alert
- The cooldown period before re-alerting
Correct answer: How often the alert condition is checked against incoming data
Evaluation frequency determines how often Azure Monitor runs the alert logic against the data window to check if the condition is met.
