What term encompasses both configuration management settings and policy as code items?

Infrastructure as code (IaC) is the correct answer because it refers to the practice of managing and provisioning computing infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. This approach allows both configuration management settings and policy as code items to be treated as code, enabling automation, versioning, and the ability to apply software development practices to infrastructure management.

In the context of IaC, configuration management settings specify how resources should be set up and maintained, while policy as code involves defining compliance and governance policies in a programmatic way. Together, they help developers and operations teams automate the deployment and management of infrastructure reliably and repeatably.

The other options, while related to software and system deployment practices, do not encapsulate the combination of configuration management settings and policy as code in the same straightforward manner as Infrastructure as code does. Continuous integration focuses on automating the integration of code changes, service orchestration deals with provisioning and managing services across multiple environments, and version control is primarily about managing changes to source code rather than infrastructure configuration and policies. Thus, Infrastructure as code is the most comprehensive term that captures both aspects.
