The answer is to create an Azure Policy assignment to deploy the Log Analytics agent. This is correct because Azure Policy’s DeployIfNotExists effect can automatically deploy the Log Analytics agent to all Azure VMs across multiple subscriptions, including both existing and future machines, ensuring continuous compliance without manual intervention. On the Microsoft Azure Security Engineer Associate AZ-500 exam, this scenario tests your understanding of automated agent deployment for Microsoft Sentinel and Defender for Cloud, where scalable solutions are key. A common trap is choosing manual installation or Azure Automation DSC, but remember that DSC handles configuration drift, not agent provisioning, while the Azure portal VM blade is a one-off task. For the exam, think “Policy pushes the agent; DSC configures the OS.” A useful memory tip: DeployIfNotExists is your “set it and forget it” tool for agent rollout across your entire Azure estate.
AZ-500 Practice Question: Secure Azure using Microsoft Defender for Cloud and Microsoft Sentinel
This AZ-500 practice question tests your understanding of secure azure using microsoft defender for cloud and microsoft sentinel. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your company has multiple Azure subscriptions and wants to use Microsoft Sentinel as a SIEM. You need to collect security events from all Azure VMs, including existing and future ones. What should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an Azure Policy assignment to deploy the Log Analytics agent.
Azure Policy with DeployIfNotExists effect can automatically deploy the Log Analytics agent to all VMs in a subscription. Option A is wrong because manual installation is not scalable. Option C is wrong because Azure Automation DSC is for configuration management, not agent deployment. Option D is wrong because the Azure portal VM blade is manual.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use the Azure portal to enable 'Security Center' on each VM.
Why it's wrong here
Enabling Security Center from portal is manual.
✗
Use Azure Automation Desired State Configuration (DSC) to push the agent.
Why it's wrong here
DSC can configure the agent but requires targeting existing VMs; policy covers future VMs.
✗
Manually install the Log Analytics agent on each VM.
Why it's wrong here
Manual installation is not scalable for many VMs.
✓
Create an Azure Policy assignment to deploy the Log Analytics agent.
Why this is correct
Azure Policy can automatically deploy the agent to all VMs in scope.

Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
