Blue-Green deployments are a progressive delivery pattern where two environments exist: Blue (current version) and Green (new version). The new version is deployed in parallel, and once validated, traffic is switched over from Blue to Green.

''Blue-Green deployments provide zero-downtime releases by running two production environments: one active and one idle. A new version is deployed to the idle environment, tested, and when ready, traffic is switched to it.''

Thus, the correct description is A.

===========

Kustomize is a Kubernetes-native configuration management tool that allows manifest customization without modifying the original YAML files. It uses overlays and patches to adapt configurations for different environments.

''Kustomize provides a declarative way to customize Kubernetes manifests by applying patches and overlays. This allows managing multiple environments without duplicating manifest files.''

Thus, the correct answer is D.

===========

In GitOps, Continuous Deployment (CD) follows after Continuous Integration (CI). CI is responsible for building and testing application code, while CD automates the delivery and deployment of these changes into runtime environments. The Git repository serves as the single source of truth, and when CI merges new changes into the main branch, CD reconciles the state of the environment to match what is declared in Git.

''GitOps builds on the principles of DevOps by using Git as the source of truth for declarative infrastructure and applications. CI pipelines handle the integration and testing of code, and CD pipelines or agents automatically reconcile the desired state in Git with the actual state in the cluster.''

This shows that CD is triggered after CI to handle deployment automation, ensuring systems remain in sync with what is declared in version control.

Infrastructure as Code (IaC) is a foundational practice in GitOps. It involves managing and provisioning infrastructure through declarative, machine-readable files rather than manual processes or GUIs. IaC ensures consistency, automation, and repeatability across environments.

''Infrastructure as Code defines and manages infrastructure through code files stored in version control. This enables automation, reproducibility, and immutability in infrastructure provisioning.''

Thus, D is correct.

===========

In GitOps, DevSecOps integrates security into the GitOps workflow by treating security policies as code and storing them in Git. This enables automatic detection of security policy drift and ensures that any misconfiguration or violation is reconciled, just like application and infrastructure code.

''GitOps applies DevSecOps by managing security policies as code. This enables detection of drift in security configurations, ensuring environments remain compliant and secure.''

Thus, the correct answer is A.
