AZ-301 Research & Evidence-Based Practice 4 — Questions and Answers
Question 1: An architect must validate that an Azure Virtual Network peering configuration meets latency SLOs with empirical data. Which Network Watcher tool measures point-to-point latency across the peered VNets?
- Network Performance Monitor (Connection Monitor v2) (Correct answer)
- Azure Traffic Analytics
- VNet flow logs
- Azure DNS metrics
Correct answer: Network Performance Monitor (Connection Monitor v2)
Connection Monitor v2 in Network Watcher continuously measures end-to-end latency and packet loss between sources and destinations across VNet peers.
Question 2: A team is researching whether Azure Front Door or Azure Traffic Manager better reduces global user latency. Which method provides the most rigorous comparative evidence?
- Deploying both in parallel with identical backends and measuring real user latency via Azure Application Insights (Correct answer)
- Reading the product documentation comparison page
- Checking Azure Advisor performance recommendations
- Reviewing Azure Service Health SLA history for both services
Correct answer: Deploying both in parallel with identical backends and measuring real user latency via Azure Application Insights
Running a live A/B test with Application Insights telemetry capturing actual user-perceived latency for both services yields the most rigorous empirical evidence.
Question 3: An evidence-based capacity planning exercise requires forecasting Azure SQL Database storage growth over 6 months. Which Azure Monitor data source provides the historical storage consumption trend needed for this projection?
- Azure SQL Database 'storage_used' metric in Azure Monitor Metrics (Correct answer)
- Azure Cost Management reserved capacity utilization
- Azure Advisor SQL recommendations
- Azure SQL Intelligent Insights logs
Correct answer: Azure SQL Database 'storage_used' metric in Azure Monitor Metrics
The 'storage_used' metric in Azure Monitor Metrics for Azure SQL Database provides historical data points that can be trended for 6-month capacity forecasting.
Question 4: To research the real-world reliability impact of enabling Availability Zones for Azure Virtual Machine Scale Sets, which data source provides the most authoritative pre-deployment evidence?
- Azure SLA documentation showing 99.99% SLA for zone-redundant VMSS vs. 99.95% for single zone (Correct answer)
- Azure Cost Management zone comparison
- Azure Advisor high availability score
- Azure Network Watcher topology view
Correct answer: Azure SLA documentation showing 99.99% SLA for zone-redundant VMSS vs. 99.95% for single zone
Microsoft's published SLA guarantees quantify the reliability difference between zone-redundant (99.99%) and single-zone (99.95%) VMSS configurations as authoritative pre-deployment evidence.
Question 5: A research workload requires querying petabytes of structured data with sub-minute response times. Which Azure evidence-based benchmark metric should guide the service selection decision?
- Azure Synapse Analytics distributed query execution time measured via query profile in Synapse Studio (Correct answer)
- Azure SQL Database DTU consumption report
- Azure Data Factory pipeline throughput metrics
- Azure Databricks cluster autoscale logs
Correct answer: Azure Synapse Analytics distributed query execution time measured via query profile in Synapse Studio
Synapse Studio's query profile shows distributed execution steps and stage-level timing, giving architects empirical evidence of query performance at petabyte scale.
Question 6: During research into Azure Key Vault access patterns, an architect discovers secrets are accessed thousands of times per hour. Which Key Vault feature provides the detailed access evidence needed to assess whether throttling is occurring?
- Key Vault diagnostic logs streamed to Log Analytics, queried for 429 status codes (Correct answer)
- Azure Advisor security recommendations
- Azure Policy key vault compliance report
- Azure Cost Management Key Vault usage metrics
Correct answer: Key Vault diagnostic logs streamed to Log Analytics, queried for 429 status codes
Key Vault diagnostic logs record every API call with HTTP status codes; filtering for 429 responses in Log Analytics provides empirical evidence of throttling incidents.
Question 7: A research team evaluating Azure Cognitive Services must provide evidence that PII data never leaves a specific Azure region. Which compliance artifact provides authoritative residency evidence?
- Azure data residency documentation and the Cognitive Services regional endpoint configuration confirmed via ARM template (Correct answer)
- Azure Security Center data classification report
- Azure Monitor activity logs showing API call destinations
- Azure Purview data map scan results
Correct answer: Azure data residency documentation and the Cognitive Services regional endpoint configuration confirmed via ARM template
Using a region-specific Cognitive Services endpoint (documented in Azure data residency guidance) combined with ARM template deployment records provides authoritative evidence that data processing stays in-region.
