CV0-004 Operations and Support Practice Question
A cloud engineer needs to apply security patches to a group of Linux VMs running in Azure. The engineer wants to automate the patching process and ensure that patches are applied during a predefined maintenance window. Which Azure service should be used?
⚠ Common exam trap
CV0-004 often tests the confusion between governance/assessment services (Azure Policy, Defender for Cloud) and the actual remediation service (Update Management) — candidates pick Policy because it sounds like it 'enforces' patching.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Update Management
Azure Update Management (now part of Azure Automation) is the purpose-built service for orchestrating OS patch deployment across Windows and Linux VMs, including Azure VMs, on-premises machines, and other clouds via the Log Analytics agent. It lets you define a maintenance window, schedule recurring patch deployments, and produce compliance reports showing which patches are missing or installed. This directly satisfies the requirement to automate patching during a predefined window.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure Security Center
Why it's wrong here
Azure Security Center (now Defender for Cloud) assesses and reports on missing patches but does not schedule or deploy them within a maintenance window. It is tempting because its patch-compliance findings imply remediation capability, yet it only surfaces recommendations. Update Manager, by contrast, orchestrates patch installation against a defined maintenance schedule.
- ✗
Azure Policy
Why it's wrong here
Azure Policy enforces configuration compliance through audit and deny effects; it cannot schedule or deploy patches to Linux VMs. It is tempting because it governs Azure resource standards, such as requiring tags or allowed regions, which is the right choice when the goal is preventing non-compliant resource deployment rather than remediating guest operating systems.
- ✗
Azure Backup
Why it's wrong here
Azure Backup provides data protection through recovery points and restore operations; it does not scan for or deploy OS package updates, so no maintenance-window patch orchestration occurs. It is tempting because it also schedules recurring jobs against VMs, but that scheduling covers snapshot and retention policies. Update Manager, by contrast, handles patch assessment and installation within defined windows.
- ✓
Azure Update Management
Why this is correct
Azure Update Manager orchestrates OS patching for Azure and Arc-connected Linux VMs, scheduling assessments and deployments inside a defined maintenance window. It satisfies the automation and windowing constraints directly, unlike manual SSH patching or image rebuilds. Note that Update Management in Azure Automation is retired; Update Manager is the current service.
