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.

Progressive deliveryis a GitOps pattern that incrementally rolls out application updates, using methods like canary releases, feature flags, and blue-green deployments. GitOps enhances this by ensuring the rollout isautomated and declaratively managed through Git, removing the need for manual traffic switching.

“GitOps enables progressive delivery by declaratively managing rollout strategies such as canary or blue-green deployments. These strategies are applied automatically by controllers, without requiring manual traffic switching.”

Thus, the correct answer isB.

Areconcilerensures that the actual system matches the desired state declared in Git. External reconcilers run outside the core cluster orchestration process.Fluxis a widely used GitOps external reconciler that continuously syncs cluster state with the repository.

“Flux is an example of a GitOps reconciler that continuously monitors Git repositories and applies changes to the cluster. As an external reconciler, it handles synchronization and reconciliation loops outside the direct application code.”

Thus,A: Fluxis 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.

In GitOps, thepull-based reconciliation approachmeans that agents continuously monitor the Desired State in Git. Unlike push-based systems, which only act when triggered, pull-based systems can reconcile at any time, providing resilience, self-healing, and security (since no external system needs direct access to the cluster).

“In a pull-based model, reconciliation agents continuously fetch and compare the desired state, enabling self-healing and ensuring the desired configuration is accessible at all times.”

Thus, the correct answer isB.

The core foundation of GitOps is that Git serves as the single source of truth for the desired state of both applications and infrastructure. This means all configuration is declared in Git in a version-controlled, auditable, and verifiable manner. Operators and reconciliation agents continuously pull these definitions to ensure the live system matches what Git declares.

“Declarative descriptions of the desired state of the system must be versioned in Git, making Git the single source of truth. This provides auditability, reliability, and enables rollbacks by reverting changes in Git.”

This principle ensures that any change in system state is traceable through Git commits, making environments predictable, reproducible, and transparent.

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.

A GitOps-managed Kubernetes cluster uses reconciliation loops to continuously compare the actual state of the system with the desired state declared in Git. When drift (divergence between declared configuration and live cluster state) is detected, the GitOps operator automatically reconciles the difference to bring the system back into alignment.

“In GitOps, a reconciliation loop ensures that the desired state as declared in Git is continuously compared with the observed state of the system. If drift is detected, the system automatically takes corrective action to reconcile the difference and restore the declared configuration.”

This ensures consistency, reliability, and self-healing. Manual intervention is not required for drift correction, as the automated reconciliation is a core principle of GitOps.

AGitOps-managed software systemis defined as one or more runtime environments whose resources are managed declaratively via GitOps practices.

“A GitOps-managed software system includes one or more runtime environments, such as clusters, where resources are under management. The desired state of these resources is declared in Git and reconciled continuously.”

Thus, the correct option isB.

TheDesired State, stored in Git, is the ultimate source of truth in GitOps. It defines how the system should look and behave. Continuous deployment processes reconcile the actual cluster state against this Desired State.

“In GitOps, the desired state kept in Git is the single source of truth. The reconciler ensures the actual state matches the desired state, guiding the continuous deployment process.”

Thus, the correct answer isA.
