AZ-301 Research & Evidence-Based Practice 3

Question 1

An architect is researching Azure cost anomalies to build evidence for a budget overrun root-cause report. Which Azure Cost Management feature detects unexpected spending spikes automatically?

Accepted Answer

Cost anomaly detection alerts in Azure Cost Management

Answer

Azure Cost Management's anomaly detection uses machine learning to identify and alert on unexpected cost spikes, providing evidence for root-cause analysis.

Question 2

When designing a research pipeline that ingests large volumes of IoT sensor data into Azure for batch analysis, which service combination is most evidence-aligned for high-throughput ingestion followed by analytics?

Accepted Answer

Azure Event Hubs for ingestion + Azure Synapse Analytics for batch processing

Answer

Event Hubs is purpose-built for millions of events per second, and Synapse Analytics provides distributed batch analytics at petabyte scale for IoT research workloads.

Question 3

A research team wants to track experiment results and model metrics for Azure Machine Learning runs to compare hypothesis outcomes over time. Which AML feature provides this capability?

Accepted Answer

Azure ML Experiments and Run History with MLflow tracking

Answer

Azure ML integrates MLflow experiment tracking, storing metrics, parameters, and artifacts per run so researchers can compare hypothesis outcomes across experiments.

Question 4

An architect needs evidence of data lineage and transformation accuracy across an Azure Data Factory pipeline for a compliance audit. Which ADF feature captures this information?

Accepted Answer

ADF Monitor pipeline run details with activity input/output logging

Answer

ADF's monitoring pane records each activity's input/output payload, duration, and status, providing auditable evidence of data lineage through the pipeline.

Question 5

To build evidence for a security posture report, an architect must aggregate security findings across 15 Azure subscriptions. Which service is designed for this multi-subscription aggregation?

Accepted Answer

Microsoft Defender for Cloud with management group scope

Answer

Defender for Cloud can be scoped to management groups, aggregating secure scores and security findings across all child subscriptions into a unified report.
