AZ-301 Research & Evidence-Based Practice 4

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?

Accepted Answer

Network Performance Monitor (Connection Monitor v2)

Answer

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?

Accepted Answer

Deploying both in parallel with identical backends and measuring real user latency via Azure Application Insights

Answer

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?

Accepted Answer

Azure SQL Database 'storage_used' metric in Azure Monitor Metrics

Answer

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?

Accepted Answer

Azure SLA documentation showing 99.99% SLA for zone-redundant VMSS vs. 99.95% for single zone

Answer

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?

Accepted Answer

Azure Synapse Analytics distributed query execution time measured via query profile in Synapse Studio

Answer

Synapse Studio's query profile shows distributed execution steps and stage-level timing, giving architects empirical evidence of query performance at petabyte scale.
