AZ-400 Monitoring and Feedback 4 — Questions and Answers
Question 1: Which Azure Monitor component is specifically designed to monitor the health and performance of containerized workloads in AKS?
- Azure Monitor for VMs
- Container Insights (Correct answer)
- Network Watcher
- Application Insights SDK
Correct answer: Container Insights
Container Insights (part of Azure Monitor) collects performance metrics and logs from AKS nodes, pods, and containers for container health monitoring.
Question 2: In Azure DevOps, what is the purpose of 'Release Gates' in a release pipeline?
- Block deployments based on branch policies
- Automatically evaluate pre/post-deployment conditions using external data sources (Correct answer)
- Require manual approval before deployment
- Limit deployments to a specific time window
Correct answer: Automatically evaluate pre/post-deployment conditions using external data sources
Release Gates query external systems (e.g., Azure Monitor alerts, REST APIs) and block or allow pipeline progression based on real-time conditions.
Question 3: A team uses Azure Monitor to track SLOs. Which feature allows them to define and visualize the percentage of time a service met its performance target?
- Metric alerts
- SLO workbooks in Azure Monitor (Correct answer)
- Log search alerts
- Azure Service Health
Correct answer: SLO workbooks in Azure Monitor
Azure Monitor provides SLO workbook templates that calculate and display error budgets and compliance percentages against defined service-level objectives.
Question 4: Which distributed tracing concept links telemetry from multiple services into a single end-to-end request flow in Application Insights?
- Dependency mapping
- Operation ID / correlation ID (Correct answer)
- Live Metrics Stream
- Profiler trace
Correct answer: Operation ID / correlation ID
Application Insights propagates an operation ID (correlation ID) across service calls, allowing all telemetry for a single user request to be linked.
Question 5: What Azure service can be used to receive and process Azure Monitor alerts via a push-based event stream for custom automated remediation?
- Azure Storage Queue
- Azure Event Hubs (Correct answer)
- Azure Notification Hubs
- Azure Service Bus Topics
Correct answer: Azure Event Hubs
Azure Event Hubs can receive Azure Monitor diagnostic data and alerts as a high-throughput event stream for downstream processing and automated remediation.
Question 6: In a continuous feedback loop for DevOps, which practice involves instrumenting code to measure user behavior and feature usage in production?
- Blue-green deployment
- Feature flag telemetry / usage analytics (Correct answer)
- Canary analysis
- Chaos engineering
Correct answer: Feature flag telemetry / usage analytics
Feature flag telemetry and usage analytics instrument specific features to measure adoption, engagement, and impact directly in production.
Question 7: Which Log Analytics function allows you to join two tables in a KQL query?
- union
- join (Correct answer)
- merge
- lookup
Correct answer: join
The `join` operator in KQL merges rows from two tables based on matching values in specified columns, similar to SQL JOINs.
