Microsoft DevOps Engineer Expert AZ-400 Practice Question

Your team manages an existing Azure Kubernetes Service (AKS) cluster that runs dozens of micro-services. You must collect real-time CPU, memory, disk, and network metrics for nodes and containers, retain container stdout/stderr logs in a Log Analytics workspace, and view a visual topology map of the cluster in the Azure portal-all without installing or configuring third-party tools. Which action should you perform first?

Install the Log Analytics agent manually on each worker node and configure performance counter collection through the workspace.
Enable Azure Monitor Container Insights for the AKS cluster and link it to an existing Log Analytics workspace.
Deploy Prometheus and Grafana inside the cluster and configure Prometheus to push metrics to Azure Monitor Metrics.
Enable VM Insights for all Kubernetes nodes by onboarding them to a Log Analytics workspace and adding the Dependency agent.

Answer Description

Azure Monitor Container Insights is specifically designed for AKS and other Kubernetes environments. Enabling it from the Azure portal (or with Azure CLI/ARM/Bicep) deploys the Azure Monitor agent as a managed add-on. The agent streams node and container performance metrics as well as container logs to the chosen Log Analytics workspace, and the solution automatically provides the Kubernetes health blades and interactive cluster map. Manually installing the Log Analytics agent, deploying Prometheus/Grafana, or enabling VM Insights will not deliver the integrated container views, topology map, nor the streamlined onboarding experience required.
