AZ-204 Research & Evidence-Based Practice 5 — Questions and Answers
Question 1: Which Application Insights feature periodically sends HTTP requests to your web app from multiple global locations and alerts you on failures or latency spikes?
- Live Metrics Stream
- Availability tests (Correct answer)
- Smart detection
- Continuous Export
Correct answer: Availability tests
Availability tests (URL ping and multi-step web tests) probe your app from worldwide Azure PoPs and trigger alerts when availability drops.
Question 2: Which Application Insights SDK method should you call to record a custom named event representing a user action or business milestone?
- TrackTrace()
- TrackException()
- TrackEvent() (Correct answer)
- TrackMetric()
Correct answer: TrackEvent()
TrackEvent() emits a named event telemetry item that you can query and count in the portal to measure specific user behaviors or business KPIs.
Question 3: What is the primary purpose of geo-replication in Azure Container Registry?
- To back up container images to a secondary storage account
- To distribute registry replicas to multiple regions for faster image pulls (Correct answer)
- To scan images for known vulnerabilities automatically
- To enforce content trust and image signing across regions
Correct answer: To distribute registry replicas to multiple regions for faster image pulls
Geo-replication creates registry replicas in chosen Azure regions so that image pulls are served from the nearest replica, reducing latency.
Question 4: Which Azure Container Instances restart policy should be selected for a one-time batch processing job that should not restart after completion?
- Always
- OnFailure
- Never (Correct answer)
- OnSuccess
Correct answer: Never
The Never restart policy ensures the container exits permanently after it finishes, which is correct for batch jobs that run once.
Question 5: What is the default data retention period for telemetry stored in an Application Insights workspace?
- 30 days
- 60 days
- 90 days (Correct answer)
- 180 days
Correct answer: 90 days
Application Insights retains telemetry for 90 days by default; retention can be extended up to 730 days in the Log Analytics workspace settings.
Question 6: In Azure Kubernetes Service (AKS), which Kubernetes Service type provisions an Azure Load Balancer with a public IP to expose pods to external internet traffic?
- ClusterIP
- NodePort
- LoadBalancer (Correct answer)
- Ingress
Correct answer: LoadBalancer
Setting type: LoadBalancer in a Service manifest causes AKS to provision an Azure public Load Balancer and assign it an external IP.
Question 7: Which Azure Monitor feature provides a query workspace where you write KQL queries against log data collected from Application Insights, VMs, and other Azure resources?
- Metrics Explorer
- Log Analytics (Correct answer)
- Activity Log
- Azure Alerts
Correct answer: Log Analytics
Log Analytics is the query interface for Azure Monitor Logs, accepting KQL queries across data ingested from any connected resource.
