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.

The first GitOps principle isDeclarative Descriptions. This means the desired system configuration (for infrastructure, services, and applications) is expressed declaratively and stored in version control. Git becomes the single source of truth.

“The desired system state must be expressed declaratively. This provides a clear, machine-readable blueprint for the system, and ensures that what is in Git is what should be running in the environment.”

Therefore,infrastructure and application configurations must be defined declaratively and stored in Git, not managed imperatively or manually.

A fundamental GitOps principle is that reconciliation isautomated and continuous. Software agents (e.g., controllers like ArgoCD or Flux) continuously pull desired state declarations from Git repositories and reconcile them with the actual state.

“Software agents automatically pull the desired state declarations from the source of truth and continuously reconcile the actual state to match.”

Thus, the correct answer isC.

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.

Kustomize is a GitOps tool for managing Kubernetes configurations declaratively. It uses afolder structure with configuration filesand akustomization.yamlfile that references resources and overlays. This enables customization without modifying the base manifests.

“Kustomize allows customization of Kubernetes manifests by organizing resources in directories and referencing them through file paths in a kustomization file. This directory-based approach supports overlays, reusability, and modular configuration.”

Thus, the correct answer isD.

ACanary Deploymentgradually introduces a new application version to a small subset of users before expanding to the full user base. This pattern allows testing and validation in production while reducing risk.

“Canary deployments progressively roll out changes to a small group of users, monitoring for issues before routing all traffic to the new version. This gradual shift minimizes risk and ensures safer releases.”

Thus, the correct answer isB.

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.

GitOps requires apull-based approachas the default model, where agents in the cluster automatically pull desired state from Git. However,push-based triggers(e.g., webhooks) can optionally be used to complement pull-based reconciliation.

“Pull-based reconciliation is required in GitOps to ensure automation and security. Push-based triggers may optionally complement this, but the pull model is fundamental.”

Thus, the correct answer isD.

ArgoCD and Flux are the two primary CNCF GitOps tools. While both are reconciliation engines, they can be used together carefully if configured properly to avoid conflicts. For example, Flux can be used to manage configuration sources, while ArgoCD handles application-level delivery. Extensions and integration points allow them to complement each other.

“ArgoCD and Flux implement the GitOps reconciliation principle. Though they provide overlapping functionality, they can be integrated by carefully managing their scope. For instance, Flux can manage sources and Helm charts, while ArgoCD handles higher-level deployments. Extensions exist to allow cooperation without conflict.”

Thus, the correct answer isC.

Prometheus is commonly used in GitOps for monitoring.Alertmanageris the tool integrated with Prometheus to handle alert routing. It supports sending alerts to external systems such as Slack, PagerDuty, or email.

“Prometheus generates alerts, which are routed and managed by Alertmanager. Alertmanager can integrate with messaging tools like Slack to deliver alerts in real time.”

Thus, the correct answer isA: Alertmanager.

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.

In GitOps, rollback is the process of reverting to a previous known-good configuration stored in Git. This is typically done when a deployment introduces abug, error, or failurethat impacts system stability.

“Rollback in GitOps is used to revert to a previous commit representing a stable configuration when the current deployment causes errors or failures.”

Thus, the correct answer isA.

Declarative configuration describeswhatthe system should look like, nothowto achieve it. This enables the use ofstandard reconciliation tools(like ArgoCD or Flux) to manage the system automatically, removing the burden of writing and maintaining imperative scripts.

“Declarative configuration enables systems to be managed by generic reconciliation tools rather than bespoke scripts, reducing operational overhead and increasing reliability.”

Thus, the correct answer isB.

In aBlue-Green deployment, two environments (Blue and Green) exist at the same time. The current version runs in one environment (Blue), and the new version is deployed to the other environment (Green). Traffic is switched to Green once the new version is validated.

“Blue-Green deployments maintain two production environments. The new version is deployed alongside the old version, and once validated, traffic is switched from Blue to Green.”

Thus, the correct answer isC.

Configuration as Code (CaC)in GitOps ensures that infrastructure and application definitions are stored in Git, version-controlled, and immutable. Unlike traditional approaches (manual changes, scripts, mutable infrastructure), GitOps uses CaC forimmutable infrastructure deployments, guaranteeing reproducibility and environment consistency.

“Configuration as Code ensures that system configuration is stored declaratively in version control. This allows immutable deployments, reproducibility, consistency across environments, and prevents ad-hoc manual changes.”

Thus, the distinct advantage isimmutable deployments and consistent environments, makingBcorrect.

In GitOps,pull-based deploymentis fundamental. Instead of pushing changes into a cluster, GitOps agents running inside the cluster continuouslypull from Gitto reconcile desired state.

“GitOps uses a pull-based model: agents inside the cluster continuously poll the Git repository for desired state changes. If changes are found, they reconcile the live system automatically to match the declared state.”

This ensures secure, automated, and consistent deployments.

Thus,Dis correct.

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, thedesired stateis stored in Git. Manual updates applied directly to the cluster (via kubectl or APIs) change theactual statewithout updating Git. This introducesdriftbetween actual and desired state.

“Manual changes to the runtime environment cause the actual state to diverge from the desired state stored in Git. This drift must be detected and reconciled automatically.”

Thus, the correct answer isC.
