AZ-801 Question #57: Real Exam Question with Answer & Explanation

Question

You have five Azure virtual machines. You need to collect performance data and Windows Event logs from the virtual machines. The data collected must be sent to an Azure Storage account. What should you install on the virtual machines?

Options

• Athe Azure Connected Machine agent
• Bthe Azure Monitor agent
• Cthe Dependency agent
• Dthe Telegraf agent
• Ethe Azure Diagnostics extension

Explanation

To collect performance data and Windows Event logs from Azure VMs and send them to an Azure Storage account, you should install the Azure Diagnostics extension.

Common mistakes.

• A. The Azure Connected Machine agent (Azure Arc agent) is used for managing on-premises or other cloud servers as if they were Azure resources, not for collecting guest-level diagnostics for Azure VMs to a storage account.
• B. While the Azure Monitor agent can collect similar data, its primary destination is typically an Azure Log Analytics workspace or Azure Monitor Metrics, not directly an Azure Storage account as the exclusive or primary destination for raw logs and performance data in this context.
• C. The Dependency agent is used by Azure Monitor's VM insights and Service Map to discover processes and dependencies between machines, not for general performance data and event log collection.
• D. The Telegraf agent is an open-source agent for collecting metrics and logs, often used with InfluxDB or other monitoring solutions, but it's not a native Azure service for this purpose and wouldn't be the default choice for sending data specifically to an Azure Storage account.
