Microsoft DevOps Engineer Expert AZ-400 Practice Question

You administer 50 Ubuntu Server Azure virtual machines that run a latency-sensitive API. During customer complaints, Azure Monitor shows low CPU utilization and normal network traffic, so you suspect guest-level memory pressure or disk bottlenecks. You need to visualize these counters in the Azure portal and configure alerts when available memory on any VM drops below 500 MB, using only native Azure Monitor capabilities. Which action should you perform first?

  • Add a diagnostic setting at the subscription level that streams the Activity Log to a Log Analytics workspace.

  • Configure an Azure Monitor metric alert based on the built-in platform metric Available Memory Bytes for the virtual machines.

  • Enable Azure Monitor VM insights, which installs the Azure Monitor agent and starts collecting guest OS performance counters for memory and disk.

  • Create a Log Analytics query that reads the Perf table for the counter Memory\Available Bytes on the existing workspace.
