  1. Which Azure Monitor feature allows you to create custom dashboards that combine metrics from multiple resources?

    Answer: Azure Monitor Workbooks

    Azure Monitor Workbooks provide flexible canvases for combining metrics, logs, and custom visualizations from multiple resources into a single interactive report.

  2. A team wants to detect anomalies in application performance automatically without setting static thresholds. Which Azure Monitor feature should they use?

    Answer: Dynamic threshold alerts

    Dynamic threshold alerts use machine learning to automatically detect anomalies based on historical patterns, removing the need for manually configured static thresholds.

  3. What is the primary purpose of the Azure Monitor Agent (AMA) compared to the legacy Log Analytics Agent?

    Answer: AMA uses Data Collection Rules for granular control over data collection

    The Azure Monitor Agent uses Data Collection Rules (DCRs) to give fine-grained, centralized control over what data is collected and where it is sent.

  4. In Application Insights, what does the 'sampling' feature primarily help with?

    Answer: Reducing telemetry cost and storage while retaining statistical accuracy

    Sampling reduces the volume of telemetry sent and stored to control costs while preserving statistical representativeness of the data.

  5. Which KQL operator would you use in Log Analytics to count the number of events grouped by a specific field?

    Answer: summarize

    The `summarize` operator aggregates rows and computes expressions such as `count()` grouped by one or more columns.

  6. A DevOps team needs to receive alerts when CPU utilization on any VM in a resource group exceeds 90% for 5 minutes. What alert scope should they configure?

    Answer: Resource group

    Setting the alert scope to the resource group lets a single alert rule monitor all VMs within that group without creating per-VM rules.

  7. Which Application Insights feature captures detailed diagnostic data only when a request fails or is slow, to minimize overhead?

    Answer: Snapshot Debugger

    Snapshot Debugger automatically collects debug snapshots when exceptions occur, letting developers inspect the call stack and variables at the point of failure.
