CV0-004 Practice Question: A cloud administrator needs to automate the…

A cloud administrator needs to automate the patching of operating systems on a fleet of EC2 instances. Which AWS service should be used?

⚠ Common exam trap

Many exam-takers confuse Amazon Inspector (which only identifies vulnerabilities) with a patching solution, or assume 'AWS Update Manager' is a real service because it sounds plausible, when in fact the correct service is AWS Systems Manager Patch Manager.

Correct answer & explanation

✓

AWS Systems Manager Patch Manager

AWS Systems Manager Patch Manager automates the process of patching managed nodes with both security-related and other types of updates. It uses a patch baseline to define which patches should be installed and can schedule patching across a fleet of EC2 instances, making it the correct service for this task.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. A cloud administrator needs to automate the process of patching multiple virtual machines in a private cloud. Which of the following is the best tool for this purpose?

easy
  • A.Virtual machine templates
  • ✓ B.Ansible playbook
  • C.SSH with manual commands
  • D.Scheduled tasks in the hypervisor management console

Why B: An Ansible playbook is the best tool for automating patching across multiple VMs because it is agentless, uses SSH for Linux or WinRM for Windows, and supports idempotent execution. This allows the administrator to define the desired patch state declaratively and apply it consistently across the entire fleet without manual intervention.
