To manage updates on an Azure Arc-enabled server using the Azure Automation Update Management solution, two primary steps are required. First, the server must have the Log Analytics agent installed and be connected to the Log Analytics workspace that is linked to the Automation account. This allows the server to report its update status and inventory. Second, the Update Management solution must be explicitly enabled for the server from within the Automation account. This action enrolls the server into the solution, making it a target for update assessments and deployment schedules.

A. Microsoft Sentinel is a Security Information and Event Management (SIEM) service used for threat detection and response, not for managing operating system updates.

B. The classic Azure Automation Update Management solution relies on the Log Analytics agent (MMA), not the Azure Monitor Agent (AMA). The AMA is used by the newer Azure Update Manager service.

1. Microsoft Learn

Azure Automation Documentation. "Enable Update Management from an Automation account". This document outlines the process

stating

"To enable it for a machine

it needs a Log Analytics workspace and an Automation account

and the machine needs to be linked to the workspace... From the list

select one or more machines to enable." This supports both connecting the machine to the workspace (Option D's goal) and enabling the solution from the Automation account (Option C).

2. Microsoft Learn

Azure Automation Documentation. "Update Management overview". Under the "Clients" section

it specifies the requirement for the Log Analytics agent: "You can enable Update Management for... physical/virtual Windows and Linux machines

both in Azure and non-Azure environments... The machine or server must have a Log Analytics agent for Windows or Linux installed and reporting to the workspace that's linked to the Automation account..." This confirms the need for the agent connection (Option D) and explicitly invalidates the use of the Azure Monitor Agent (Option B) for this solution.

3. Microsoft Learn

Azure Monitor Documentation. "Connect Windows computers to Azure Monitor". This guide details how to connect on-premises machines to a Log Analytics workspace by installing the Log Analytics agent. The procedure involves navigating to the workspace in the Azure portal and using the "Agents management" blade (previously named "Virtual machines" under data sources) to get the necessary agent setup files and workspace credentials. This directly corresponds to the action described in Option D.
