What is Infrastructure as Code (IaC), and why is it important for CI/CD?

• A way to automate infrastructure testing

• A technique to improve user experience

• A strategy to reduce coding errors

• A method to write code faster

How can automated infrastructure testing prevent deployment failures?

• By reducing the size of the application

• By increasing the number of servers

• By verifying configurations before deployment

• By ensuring all code is perfect

Give an example of how infrastructure testing ensures system reliability.

• Increasing the number of users during testing

• Simulating traffic load to check server capacity

• Reducing the number of features in the app

• Testing user feedback before launch
