In GitOps, thepull-based modelcontinuously reconciles the actual state with the desired state. This makes it resilient to drift, since reconciliation runs regularly. In contrast,event-driven systemsonly 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 isD.

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.

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,reconcilersensure the actual state matches the desired state. Reconcilers may run inside the cluster (in-cluster) or outside (external). The choice depends primarily on operational scale and the complexity of reconciliation logic.

“When determining reconciler placement, factors such as the size of the environment, the operational complexity of the reconciler, and the performance requirements should be evaluated. In-cluster reconcilers are common for straightforward deployments, while external reconcilers may be chosen for large-scale or complex systems.”

Thus, the most important considerations arecluster sizeandcomplexity of reconciler logic, makingBcorrect.

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.

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.

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.

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.

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.

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.

The reconciliation loop is a fundamental GitOps principle. It continuously compares thedesired state(stored in Git) with theactual state(running in the system). When a divergence (drift) is detected, the reconciler automatically corrects the system to match the desired state.

“The reconciliation loop ensures the system is continuously converging toward the declared desired state. Whenever the actual state deviates, the loop reconciles the system to match the desired state.”

Thus, the correct answer isC.

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.

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.

In GitOps, rollback is performed by reverting the system’sDesired Statestored in Git. This is done with thegit revertcommand, which creates a new commit that undoes the changes introduced by a previous commit.

“Because Git provides an immutable history of changes, rollbacks are straightforward. Reverting to a previous configuration is accomplished by reverting the commit in Git, which then allows the reconciler to apply the earlier desired state.”

Thus, the correct answer isB: git revert.

The GitOps principle ofVersioned and Immutablerequires Desired State to be stored in a way that enforcesimmutability and versioning. This ensures every change is recorded, auditable, and reversible.

“Desired state must be kept in an immutable, version-controlled system. This guarantees a full history of changes and enables safe rollbacks.”

Thus, the correct answer isD.

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.

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.
