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.

Linting tools are essential in GitOps practices for maintaining consistency, standardization, and quality in configuration files. Automated linters can validate YAML manifests, Helm charts, or Kustomize overlays for formatting and best practices.

“Linters automate the enforcement of formatting and quality rules in declarative configuration files. They ensure standardized structure and reduce errors in GitOps workflows.”

Thus, the correct answer isC.

Kustomizeis 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 isD.

Infrastructure as Code (IaC)is a foundational practice in GitOps. It involves managing and provisioning infrastructure throughdeclarative, machine-readable filesrather 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,Dis correct.

GitOps is not a replacement for DevOps.Instead, it is an evolution and practical implementation of DevOps principles, using Git as the single source of truth and continuous reconciliation as the operational model.

“GitOps builds on the foundation of DevOps by providing a framework to put its principles into practice. It leverages Git and declarative reconciliation to realize DevOps goals.”

Thus, the best description of the relationship isB.

The process of keeping theactual statein sync with thedesired stateis calledReconciliation. GitOps controllers (e.g., ArgoCD, Flux) continuously reconcile system resources to match what is declared in Git.

“Reconciliation is the process by which agents compare the actual system state to the desired state and automatically make changes to converge them.”

Thus, the correct answer isA: Reconciliation.

Terraform (or OpenTofu)uses a declarative model and maintains astate fileto track the current status of resources, enabling it to plan and reconcile changes.Ansible, by contrast, is more procedural and executes tasks in afire-and-forgetmanner, without tracking persistent resource state.

“Terraform maintains state for each managed resource, enabling planned, consistent changes. Ansible executes tasks without tracking resource state, working in a fire-and-forget model.”

Thus, the correct answer isB.

AState Storein GitOps is the system of record whereDesired State declarationsare kept. It must be immutable and versioned to ensure full auditability, traceability, and rollback capabilities. Git itself is the most common State Store.

“The Desired State must be stored in a State Store that is versioned and immutable. This guarantees traceability and enables recovery by reverting to previous commits.”

Thus, the correct answer isD.
