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.

In GitOps,everything that defines the system, including dashboards, must be stored declaratively in Git(the Desired State store). This ensures dashboards are versioned, reproducible, and consistent across environments.

“GitOps requires that all system components, including monitoring and observability configurations such as dashboards, are declared in Git. This ensures they are versioned, immutable, and reproducible.”

Thus,Dis correct.

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.

Most GitOps tools (e.g., Flux) are pull-based only. However,ArgoCDsupports both pull-based reconciliation (via continuous monitoring) and an optionalpush-based model, where changes can be triggered via webhooks or CI pipelines.

“ArgoCD supports both pull-based reconciliation, where the controller watches the repository, and an optional push-based reconciliation mode triggered by webhooks.”

Thus, the correct answer isA: ArgoCD.

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.

ThePulled AutomaticallyGitOps principle refers to the way software agents continuously access theDesired Statestored in the State Store (e.g., Git). Agents automatically pull the state from the repository and reconcile the system accordingly.

“Software agents automatically pull the desired state declarations from the source of truth (State Store) and continuously reconcile the system to match.”

Thus, the correct answer isD.

One of the GitOps principles isVersioned and Immutable, which requires that the Desired State is stored in a system that maintains acomplete version history. This allows for auditing, traceability, and rollback.

“The Desired State must be stored in a versioned, immutable system. The State Store must retain a complete version history so changes can be audited and previous states can be restored.”

Thus, the correct answer isB.

TheDesired Statein GitOps is the declarative specification of how the system should behave. It is stored in Git and serves as the reference point for reconciliation against the actual state.

“The desired state is a complete specification of the system stored in Git. It acts as the blueprint from which the actual state is continuously reconciled, ensuring the system remains consistent and reproducible.”

Thus, theprimary purpose of Desired Stateis to act as ablueprintto recreate and ensure consistency of the system.

GitOps enhancesDevSecOpsby ensuring security-related configurations and changes are stored in version control, where acomplete audit historyis available. This provides traceability, accountability, and compliance enforcement.

“With GitOps, the entire version history of desired state changes is stored immutably in Git. This audit trail supports security and compliance goals in DevSecOps practices.”

Thus, the correct answer isB.
