False

**The Agile movement primarily improved the pace of feature delivery by software teams

True

**IaC makes it possible to rebuild infrastructure by re-running scripts, reducing the need for manual troubleshooting

True

**Terraform scripts can be used interchangeably with cloud-specific IaC platforms like AWS CloudFormation

False

**What cultural shift does DevOps introduce to software development and operations?

DevOps integrates software development and operations teams, emphasizing collaboration, incremental releases, and automated workflows to streamline software delivery and deployment.

**Name two books that capture the principles of DevOps

The Phoenix Project (2013) and The DevOps Handbook (2016).

**What are some benefits of using Infrastructure as Code?

IaC simplifies knowledge requirements, speeds up environment creation, reduces risks, enhances compliance, and makes errors less likely.

**Why might an organization choose Terraform over a cloud-specific IaC platform?

Terraform allows for cross-platform infrastructure scripting, making it ideal for environments that use multiple cloud providers.
