AZ-400 Monitoring and Feedback 5 — Questions and Answers
Question 1: Which Azure Monitor alert type is best suited to trigger when a specific event appears in an Azure Activity Log, such as a VM being deallocated?
- Metric alert
- Log search alert
- Activity log alert (Correct answer)
- Smart detection alert
Correct answer: Activity log alert
Activity log alerts monitor the Azure control plane and fire when specific administrative or service health events are recorded in the Activity Log.
Question 2: In Application Insights, what is 'Application Map' primarily used for?
- Showing geographic distribution of users
- Visualizing dependencies and call relationships between application components (Correct answer)
- Mapping source code to deployed binaries
- Displaying alert rule topology
Correct answer: Visualizing dependencies and call relationships between application components
Application Map provides a visual topology of all components and their dependencies, highlighting failure rates and latency between services.
Question 3: A team wants to automatically create an Azure DevOps bug when an Application Insights smart detection rule identifies a performance degradation. What is the recommended integration mechanism?
- Polling Application Insights REST API on a timer
- Configuring an Action Group with an Azure DevOps work item action (Correct answer)
- Using a Logic App to scrape Application Insights dashboards
- Manually exporting smart detection results
Correct answer: Configuring an Action Group with an Azure DevOps work item action
Action Groups support an Azure DevOps work item action that automatically creates bugs or other work item types when an alert or smart detection rule fires.
Question 4: Which Azure DevOps Analytics widget shows the team's historical sprint-over-sprint delivery throughput to aid in future sprint planning?
- Cumulative Flow Diagram
- Velocity (Correct answer)
- Lead Time
- Cycle Time
Correct answer: Velocity
The Velocity widget tracks completed work (story points or item count) per sprint over time, giving teams a baseline for forecasting future sprint capacity.
Question 5: What is the difference between 'availability tests' and 'synthetic monitoring' in Application Insights?
- They are completely separate products
- Availability tests are a type of synthetic monitoring that pings URLs or runs multi-step web tests (Correct answer)
- Synthetic monitoring uses real user traffic while availability tests do not
- Availability tests require an on-premises agent
Correct answer: Availability tests are a type of synthetic monitoring that pings URLs or runs multi-step web tests
Availability tests in Application Insights are a form of synthetic monitoring that proactively sends requests to your endpoints from distributed worldwide locations.
Question 6: Which Azure Monitor feature enables you to define a recurring schedule for evaluating a log query and storing the results as a metric for long-term trending?
- Scheduled Query Rules (log alerts) (Correct answer)
- Diagnostic Settings
- Metric Alerts with dimensions
- Data Collection Rules
Correct answer: Scheduled Query Rules (log alerts)
Scheduled Query Rules run KQL log queries on a defined schedule and can emit custom metric values, enabling log-based data to be treated as metrics for trending.
Question 7: In Azure Monitor, what is the purpose of 'Diagnostic Settings' on an Azure resource?
- Configure alert thresholds for the resource
- Route resource logs and metrics to a destination such as Log Analytics, Event Hubs, or Storage (Correct answer)
- Enable Application Insights on the resource
- Define data collection rules for the resource
Correct answer: Route resource logs and metrics to a destination such as Log Analytics, Event Hubs, or Storage
Diagnostic Settings configure which platform logs and metrics a resource exports and where they are sent—Log Analytics workspace, Event Hubs, or Storage Account.
