What is configuration drift in IT systems?

Configuration drift happens when a system's settings change over time from the original or desired setup, often causing unexpected behavior.

beginner

Why is detecting configuration drift important?

Detecting drift helps keep systems secure, stable, and consistent by finding changes that might cause errors or vulnerabilities.

Which PowerShell cmdlet can be used to compare current system settings to a baseline for drift detection?

You can use Compare-Object to compare current configuration data with a saved baseline to find differences.

What is a simple way to store a baseline configuration in PowerShell?

You can export system settings to a file using Export-CliXml or Export-Csv to save the baseline for later comparison.

How can automation help with configuration drift detection?

Automation scripts can regularly check system settings against the baseline and alert you if changes are found, saving time and reducing errors.

What does configuration drift mean?

A System hardware is upgraded

B System settings have changed from the original setup

C New software is installed

D System is running faster than usual

D New-Item

Compare-Object compares two collections and shows differences.

What is a good practice to detect configuration drift?

A Manually check settings once a year

B Only check after system crashes

C Ignore small changes

D Regularly compare current settings to a saved baseline

Regular comparisons to a baseline help catch drift early.

Which file format can be used to save baseline configurations in PowerShell?

A .csv

B .exe

C .mp3

D .jpg

CSV files can store configuration data in a readable format.

How does automation improve configuration drift detection?

A By automatically checking and alerting on changes

B By deleting old configurations

C By making manual checks slower

D By ignoring changes

Automation regularly checks configurations and alerts you to changes, improving reliability.

Explain what configuration drift is and why it matters in system management.

Think about how changes over time can affect a system's behavior.

Describe a simple PowerShell approach to detect configuration drift using baseline files.

Consider saving settings and comparing them later.
