Microsoft Azure Administrator (AZ104) Practice Exam

You deployed a Linux virtual machine named VM1. What should you use to monitor the metrics and logs of VM1?

1. Linux Diagnostic Extension (LAD) 3.0

2. Azure Analysis Services

3. The AzurePerformanceDiagnostics extension

4. Azure HDInsight

The correct answer is: Linux Diagnostic Extension (LAD) 3.0

Using the Linux Diagnostic Extension (LAD) 3.0 is the appropriate choice for monitoring metrics and logs of a Linux virtual machine like VM1. This tool is specifically designed to collect and report various performance metrics and logs from Linux virtual machines in an Azure environment. LAD 3.0 enables the gathering of telemetry data such as CPU usage, memory usage, disk I/O, and network statistics, as well as operating system logs. It integrates seamlessly with Azure Monitor, thereby allowing for enhanced insights into the performance and operational health of the VM. The extension simplifies the configuration of monitoring processes and supports features such as log analytics, alerting, and visualizing data through Azure dashboards. In contrast, other options do not serve the purpose of directly monitoring a Linux virtual machine. Azure Analysis Services, for instance, is geared towards data modeling and analytics rather than VM performance metrics. The Azure Performance Diagnostics extension, while relevant for performance troubleshooting, is not the standard for continuous metrics monitoring. Azure HDInsight is a cloud service that helps to process big data workloads using open-source frameworks, and it does not pertain to VM monitoring directly. Hence, LAD 3.0 is the most suitable solution in this scenario.
