Hotspot Question Your company deploys several Linux and Windows virtual machines (VMs) to Azure. The VMs are deployed with the Microsoft Dependency Agent and the Microsoft Monitoring Agent installed…
The correct answer is Analyze Network Security Group (NSG) flow logs for VMs attempting internet access.: Azure Network Watcher; Visualize the VMs with their different processes and dependencies on other computers and external processes.: Azure Service Map. This hotspot question tests knowledge of Azure monitoring services appropriate for hybrid environments with both Linux and Windows VMs, where the Microsoft Dependency Agent and Microsoft Monitoring Agent (MMA) are already installed.

Explanation
This hotspot question tests knowledge of Azure monitoring services appropriate for hybrid environments with both Linux and Windows VMs, where the Microsoft Dependency Agent and Microsoft Monitoring Agent (MMA) are already installed.
Approach. Azure Monitor VM Insights (formerly Azure Monitor for VMs) is the correct service because it leverages both the Microsoft Monitoring Agent (MMA/Log Analytics Agent) and the Microsoft Dependency Agent to provide performance monitoring and service map (dependency mapping) for both Linux and Windows VMs - whether in Azure or on-premises via ExpressRoute. Azure Log Analytics (a feature of Azure Monitor) is used as the backing workspace to collect, store, and query the telemetry data from both agents. The Dependency Agent specifically enables the 'Map' feature in VM Insights, which visualizes network connections and dependencies between VMs. Together, VM Insights + Log Analytics Workspace provide complete coverage for the described scenario, including hybrid on-premises machines connected via ExpressRoute.
Concept tested. Understanding which Azure monitoring services utilize the Microsoft Monitoring Agent (MMA) and Microsoft Dependency Agent - specifically Azure Monitor VM Insights for performance and dependency mapping, and Log Analytics Workspace for data ingestion and querying - in a hybrid Azure and on-premises environment connected via ExpressRoute.
