CAS-004 Practice Question: Needs to ensure consistent configuration across…
An organization needs to ensure consistent configuration across multiple Linux servers. They want to automate this process with a solution that requires minimal agent installation and uses push-based communication. Which approach is most appropriate?
⚠ Common exam trap
Test-takers frequently confuse agent-based tools like Puppet or DSC with agentless ones, or assume that containerization inherently reduces agent footprint, when in fact it introduces its own runtime dependencies.
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
✓
Use Ansible playbooks to define and enforce server configurations.
Ansible is the most appropriate choice because it is agentless (no agent installation required) and uses push-based communication over SSH to enforce configurations. It uses YAML-based playbooks to define desired states, making it ideal for automating consistent configuration across multiple Linux servers with minimal overhead.
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 PowerShell Desired State Configuration (DSC) with Linux extensions.
Why it's wrong here
PowerShell DSC is primarily for Windows and requires significant setup for Linux.
- ✓
Use Ansible playbooks to define and enforce server configurations.
Why this is correct
Ansible is agentless, uses SSH for push, and is widely used for configuration management.
- ✗
Run a Docker container on each server with a configuration management tool inside.
Why it's wrong here
This adds overhead and does not directly manage host OS configuration.
- ✗
Deploy Puppet with a master server and agents on each system.
Why it's wrong here
Puppet requires agents and is pull-based, conflicting with the requirement for push-based communication.
