Exam SC-200 topic 2 question 30 discussion

The Azure Connected Machine agent is required to connect the on-premises Linux servers to the Azure subscription and integrate them with Microsoft Defender for Cloud. The agent enables communication between the servers and the Defender for Cloud service, allowing security events and data to be collected and analyzed. Once the Azure Connected Machine agent is installed, you can then install the Log Analytics agent to collect security data from the servers and send it to the Log Analytics workspace in Azure. This will allow you to use Defender for Cloud to monitor the security of your Linux servers, identify threats, and respond to security incidents.

I will go with C first, then LA-Agent: https://learn.microsoft.com/en-us/azure/defender-for-cloud/plan-defender-for-servers-agents

C for arc, few nuffies floating around on this one: Yes, you could onboard with just AMA agent but with limitations. You can install only the Azure Monitoring Agent (AMA) on on-prem Linux servers and connect them to Defender for Cloud, but they won’t be fully onboarded as Defender for Servers (Plan 1 or Plan 2) requires Azure Arc for full functionality.

Scaling your QA process for large projects requires robust testing automation tools. These tools allow you to handle extensive test cases efficiently by automating repetitive and time-consuming tasks like regression testing. Automation enables parallel test execution, significantly reducing testing time as the project grows. With the ability to integrate into CI/CD pipelines, these tools ensure continuous testing, providing rapid feedback on code changes. Moreover, automated testing improves accuracy, consistency, and coverage, ensuring that even large, complex systems maintain high quality. By leveraging testing automation tools, you can scale your QA processes without compromising speed or reliability.

Answer is: C This is an indeed a tricky question. Focus what is the goal in the question. Log Analytics Agent can be manually installed on an on-premise machine without first installing azure connected machine (ACM) agent. However, the recommended method is to use ACM, as it provides many other features. Because of this reason, I'll go with C. Ref: https://learn.microsoft.com/en-us/azure/azure-monitor/agents/log-analytics-agent#linux-virtual-machine-on-premises-or-in-another-cloud The Azure Connected Machine agent package contains several logical components bundled together. https://learn.microsoft.com/en-us/azure/azure-arc/servers/agent-overview#agent-components

The Log Analytics agent or Azure Monitor Agent for Windows and Linux is required in order to: Proactively monitor the OS and workloads running on the machine Manage it using Automation runbooks or solutions like Update Management Use other Azure services like Microsoft Defender for Cloud

https://learn.microsoft.com/en-us/azure/azure-arc/servers/agent-overview The Azure Connected Machine agent enables you to manage your Windows and Linux machines hosted outside of Azure on your corporate network or other cloud providers. *Note The Azure Monitor agent (AMA) is a separate agent that collects monitoring data, and it does not replace the Connected Machine agent; the AMA only replaces the Log Analytics agent, Diagnostics extension, and Telegraf agent for both Windows and Linux machines.

This document suggests that Azure Arc must be installed before Log Analytics from non-Azure resources. https://learn.microsoft.com/en-us/azure/defender-for-cloud/quickstart-onboard-machines The connected machine agent looks to be a component of Arc. https://learn.microsoft.com/en-us/azure/azure-arc/servers/agent-overview

Log Analytics agent should be installed on your Linux-based Azure Arc machines source: https://learn.microsoft.com/en-us/azure/defender-for-cloud/quickstart-onboard-machines#:~:text=Log%20Analytics%20agent%20should%20be%20installed%20on%20your%20Linux%2Dbased%20Azure%20Arc%20machines

The Azure Connected Machine agent enables you to manage your Windows and Linux machines hosted outside of Azure on your corporate network or other cloud providers

the azure connected machine agent aka azure arc agent is needed for every machine asset outside of azure

Correct

Which is correct ?? so much confusion on B and C ?

When you onboard to AMA Azure Machine agent it automatically onboard you to defender. The question is asking for you to protect the machines not ingest logs. You want to protect the servers. The correct answer is C

Arc his overkill here, Defender for Cloud is key. https://learn.microsoft.com/en-us/azure/defender-for-cloud/quickstart-onboard-machines#connect-on-premises-machines-by-using-the-azure-portal

I will go for B

As this question has nothing mentioned about Azure ARC and there is an option to onbaord Linux VMs onprem without ARC, I go with B - Log Analytics. As described in the doc below, the Linux machine get's onboarded after wget-ing the required Workspace package (through Log Analytics) and then it becomes available in Defender for Cloud without ARC (which would have required the Azure Connected Machine agent). https://learn.microsoft.com/en-us/azure/defender-for-cloud/quickstart-onboard-machines#onboard-your-linux-server
