Answer : A

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 a bug, error, or failure that 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 is A.

Answer : D

In GitOps, the pull-based model continuously reconciles the actual state with the desired state. This makes it resilient to drift, since reconciliation runs regularly. In contrast, event-driven systems only reconcile when an event occurs (e.g., a webhook), which makes them more prone to drift if changes happen outside those events.

''A pull-based reconciliation loop ensures continuous alignment with the desired state. Event-driven reconciliation, triggered only on events, risks system drift if changes occur outside those triggers.''

Thus, the correct answer is D.

Answer : A

Most GitOps tools (e.g., Flux) are pull-based only. However, ArgoCD supports both pull-based reconciliation (via continuous monitoring) and an optional push-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 is A: ArgoCD.

Answer : A

The Desired State in 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, the primary purpose of Desired State is to act as a blueprint to recreate and ensure consistency of the system.

Answer : D

Kustomize is a GitOps tool for managing Kubernetes configurations declaratively. It uses a folder structure with configuration files and a kustomization.yaml file 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 is D.
