NEW QUESTION # 18
In a GitOps-managed workflow, what is the correct way to initiate rollback?
- A. Create a new version based on a former version so you always "roll forward".
- B. Use Helm to rollback to a previous release version.
- C. Overwrite your existing version with the code from your last working version.
- D. Revert to an older version and force push to the main branch.
Answer: A
Explanation:
In GitOps, rollback is handled via version control. However, the practice is not to overwrite history but toroll forwardby creating a new version that reverts to the configuration of a previous known-good commit. This maintains immutability and a complete audit trail.
"With GitOps, changes are versioned immutably. Rollbacks are performed by rolling forward to a commit that represents a previous known-good configuration, ensuring history is preserved." Thus, the correct GitOps approach isB.

NEW QUESTION # 19
In the context of GitOps, what source of truth guides the continuous deployment process?
- A. Desired State
- B. Current State
- C. Fleeting State
- D. Dynamic State
Answer: A
Explanation:
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.
References:GitOps Terminology (CNCF GitOps Working Group).
NEW QUESTION # 20
In GitOps, what is the process of ensuring the actual state of a system matches its Desired State called?
- A. Reconciliation
- B. Manual Intervention
- C. Webhooks
- D. Monitoring
Answer: A
Explanation:
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.
References:GitOps Terminology (CNCF GitOps Working Group).
NEW QUESTION # 21
You are working on a GitOps project and want to trigger a reconcile process before the next scheduled reconciliation. What is the recommended way to do this?
- A. Use a webhook to trigger the reconcile process based on events or changes in the Git repository.
- B. Manually execute a script to initiate the reconcile process on the cluster using GitOps tool CLI commands.
- C. Schedule a cron job to run the reconcile process periodically, using RBAC to authenticate.
- D. Adjust the reconcile process interval time.
Answer: A
Explanation:
Although reconciliation is continuous in GitOps, tools often allow reconciliation to be triggered earlier than the normal polling interval. The recommended approach is to usewebhooks from the Git repository, which notify the GitOps controller of changes and trigger an immediate reconcile.
"While reconciliation loops continuously compare desired and actual state, reconciliation can be triggered sooner by webhooks from version control events, ensuring timely application of changes." Thus, the correct answer isA.
References:GitOps Principles (CNCF GitOps Working Group), Reconciliation and Webhooks.
NEW QUESTION # 22
Can you choose one example whereConfiguration as Codemay be utilized to manage an application's configuration and source code?
- A. Using a GUI-based configuration tool to visually configure and manage the source code of a microservices architecture.
- B. Using a Helm chart to define and manage the configuration and container image of a web application deployed on Kubernetes.
- C. Using a manual process of editing configuration files and manually syncing the source code of a monolithic application.
- D. Using a spreadsheet to manually update and manage the configuration and source code of a mobile application.
Answer: B
Explanation:
Configuration as Codeis a GitOps-related practice where configurations are stored as declarative definitions in version control. Helm charts, for example, allow applications deployed on Kubernetes to have both their container images and configuration specified declaratively.
"Configuration as Code enables teams to manage application and infrastructure configuration in version control systems, using declarative approaches such as Kubernetes manifests or Helm charts. This ensures repeatability, automation, and auditability." Thus,Helm chartsare a prime example of this practice, makingCcorrect.

NEW QUESTION # 23
Which deployment and release pattern involves gradually shifting traffic from an old version of an application to a new one?
- A. Canary Deployment
- B. Red/Black Deployment
- C. Blue-Green Deployment
- D. A/B Deployment
Answer: A
Explanation:
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.

NEW QUESTION # 24
In GitOps practices, when does CD take part?
- A. CI plays a significant role in GitOps practices.
- B. CD takes part before CI stage in order to ensure the successful deployment of applications.
- C. CD takes part simultaneously with CI, both components of GitOps practices.
- D. CD takes part after CI to automate the deployment of applications based on changes in the Git repository.
Answer: D
Explanation:
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.

NEW QUESTION # 25
Which GitOps tool has the option for a push-based reconciliation model?
- A. Flux
- B. ArgoCD
- C. Argo Workflows
- D. Flagger
Answer: B
Explanation:
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.
References:GitOps Tooling (CNCF GitOps Working Group), ArgoCD documentation on reconciliation models.
NEW QUESTION # 26
Which of the following best describes the role of Git as the "single source of truth" in GitOps?
- A. Git acts as the sole system of record for both infrastructure and application declarative configurations.
- B. Git is optional in GitOps; any version control system or manual configuration management can serve the same purpose.
- C. Git is primarily used for versioning, but runtime configurations are excluded from GitOps workflows.
- D. Git stores only application source code, while deployment configurations are managed elsewhere.
Answer: A
Explanation:
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.
References: GitOps Principles (CNCF GitOps Working Group),Principle 1: The desired system state is declarative and versioned in Git repositories.
NEW QUESTION # 27
What doesPulled Automaticallyrefer to?
- A. It always refers to Git pull.
- B. Webhooks informing the system about new commits.
- C. Accessing the Desired State from the State Store.
- D. A GET request to a relational database.
Answer: C
Explanation:
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.
References:GitOps Principles (CNCF GitOps Working Group).
NEW QUESTION # 28
You are working on a GitOps project and need to understand the similarities and differences between pull- based messaging systems and event-driven systems. What is a key difference between these two types of systems?
- A. When only events trigger reconciliation, the system is more vulnerable to drift caused by other things.
- B. Event-driven systems are less flexible and scalable compared to pull-based systems.
- C. Pull-based systems are more efficient in handling real-time events.
- D. Pull-based systems require a constant network connection to receive updates.
Answer: A
Explanation:
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.
References:GitOps Related Practices (CNCF GitOps Working Group), Reconciliation Models.
NEW QUESTION # 29
What is one of the key benefits of a pull-based reconciliation approach to configuration management?
- A. Simplified troubleshooting and debugging processes.
- B. Immediate response time to configuration changes.
- C. The CI has access credentials to the running system.
- D. Agents can access the Desired State at any time, not only when an event is triggered.
Answer: D
Explanation:
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.
References:GitOps Principles (CNCF GitOps Working Group), Pull vs. Push reconciliation models.
NEW QUESTION # 30
A GitOps project wants to leverage both ArgoCD and Flux for a deployment. Can ArgoCD and Flux be used in conjunction?
- A. If you modify their source code, ArgoCD and Flux can only be used together.
- B. ArgoCD and Flux can be used together, leveraging a drop-in extension for ArgoCD, ensuring that both reconciliation engines do not conflict.
- C. ArgoCD and Flux cannot be used together as they are designed for different types of deployments.
- D. ArgoCD and Flux cannot be used together as they have conflicting functionalities.
Answer: B
Explanation:
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.

NEW QUESTION # 31
When using Kustomize, how are resources, configurations, and customizations commonly organized?
- A. In separate configuration files for each resource.
- B. Using a combination of folder directories and referenced folder/file paths.
- C. By specifying all resources inline in the customization file.
- D. In a single configuration file.
Answer: B
Explanation:
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.
References:GitOps Tooling (CNCF GitOps Working Group), Kustomize practices.
NEW QUESTION # 32
Which statement describes Blue-Green deployments?
- A. Blue-Green deployments involve deploying the new version of an application to a subset of users and gradually expanding the deployment based on feedback.
- B. Blue-Green deployments involve deploying the new version of an application alongside the old version and switching traffic to the latest version once it is ready.
- C. Blue-Green deployments involve deploying different versions of an application in other regions and routing traffic based on geographic location.
- D. Blue-Green deployments involve deploying only one version at a time.
Answer: B
Explanation:
Blue-Green deployments are aprogressive delivery patternwhere two environments exist: Blue (current version) and Green (new version). The new version is deployed in parallel, and once validated, traffic is switched over from Blue to Green.
"Blue-Green deployments provide zero-downtime releases by running two production environments: one active and one idle. A new version is deployed to the idle environment, tested, and when ready, traffic is switched to it." Thus, the correct description isA.
References:GitOps Patterns (CNCF GitOps Working Group), Progressive Delivery patterns.
NEW QUESTION # 33
In a GitOps framework, what distinct advantage does Configuration as Code (CaC) provide in comparison to traditional infrastructure management approaches?
- A. CaC in GitOps exclusively automates the documentation process, whereas traditional approaches focus on manual documentation.
- B. CaC is less secure and more complex than traditional infrastructure management.
- C. In GitOps, CaC enables dynamic resource allocation during runtime, contrasting with the static configurations in traditional methods.
- D. GitOps leverages CaC for immutable infrastructure deployments, ensuring consistent environments, unlike traditional methods that allow ad-hoc changes.
Answer: D
Explanation:
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.

NEW QUESTION # 34
How do you ensure that you are achieving thePulled AutomaticallyGitOps principle?
- A. By maintaining multiple Git repositories for different aspects of your infrastructure and applications.
- B. By deploying changes from the version control repository by applying them through an automated pipeline when major updates are needed.
- C. By manually triggering deployments and configurations using scripts and commands.
- D. By having an operator continuously monitor and pull changes from the source of truth.
Answer: D
Explanation:
ThePulled Automaticallyprinciple in GitOps means that agents inside the runtime environment (e.g., controllers/operators) continuously monitor Git (the source of truth) andautomatically pull changeswhen updates are detected.
"Software agents continuously pull changes from the version control system and reconcile them automatically. This pull-based approach ensures automation, security, and self-healing." Thus, the correct answer isB.
References:GitOps Principles (CNCF GitOps Working Group),Principle 4: Continuously reconciled and pulled automatically.
NEW QUESTION # 35
What does the GitOps reconciliation loop ensure?
- A. Only applies changes but does not remove resources that used to be part of the Desired State.
- B. The Desired State is applied to the system when the current system state diverges from the Desired State.
- C. That the Desired State is instantaneously applied to the system.
- D. When manifests have errors, it will ensure that as much as possible still gets applied.
Answer: B
Explanation:
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.
References:GitOps Principles (CNCF GitOps Working Group).
NEW QUESTION # 36
How can you achieve the declarative GitOps principle in managing infrastructure and applications?
- A. By periodically creating manual backups of your infrastructure configurations.
- B. By using imperative scripting languages to automate infrastructure changes.
- C. By defining and maintaining infrastructure and application configurations declaratively in a version- controlled system.
- D. By manually making ad-hoc configuration changes directly in the production environment.
Answer: C
Explanation:
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.
References:GitOps Principles (CNCF GitOps Working Group),Principle 1: The system is described declaratively.
NEW QUESTION # 37
Which of the following statements accurately describes the role of GitOps in progressive delivery?
- A. GitOps allows end users to perform progressive delivery automatically without manually shifting traffic.
- B. GitOps requires end users to manually shift traffic for progressive delivery.
- C. GitOps only works with manual progressive delivery without any automation.
- D. GitOps does not allow end users to perform progressive delivery automatically, only manually.
Answer: A
Explanation:
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.
References:GitOps Patterns (CNCF GitOps Working Group), Progressive Delivery practices.
NEW QUESTION # 38
In GitOps, how is the Desired State stored?
- A. In a way that retains only the latest version.
- B. In a way that enforces mutability and versioning.
- C. In a way that enforces immutability and versioning.
- D. In a way that permits direct modifications to live systems.
Answer: C
Explanation:
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.
References:GitOps Principles (CNCF GitOps Working Group).
NEW QUESTION # 39
In GitOps, what does it mean toContinuously Reconcile?
- A. Automatically compare and adjust the system state as needed.
- B. Monitor the system for any unauthorized changes and revert them.
- C. Regularly update Git repositories with the latest changes from external sources.
- D. Perform regular backups of Git repositories.
Answer: A
Explanation:
Continuous reconciliationis another core GitOps principle. It means that software agents (operators or controllers) run loops that continuously observe the live system and compare it against the desired state declared in Git. If any divergence (drift) is found, the agentautomatically reconcilesthe system to match the declared configuration.
"Software agents continuously observe the actual system state and compare it with the desired state declared in Git. If a divergence is detected, the agents automatically reconcile the difference to bring the system back into alignment." This providesautomation, consistency, and self-healing, which are hallmarks of GitOps.
References:GitOps Principles (CNCF GitOps Working Group),Principle 4: Continuously reconciled.
NEW QUESTION # 40
Would you implement DevSecOps culture in CI/CD pipelines?
- A. No, because CI/CD systems are incompatible with the DevSecOps culture.
- B. Yes, DevSecOps is essential for CI/CD pipelines. It helps build software without any security issues.
- C. No, because CI/CD systems are totally secure by design.
- D. No, DevSecOps focuses only on security outside of CI/CD pipelines.
Answer: B
Explanation:
DevSecOpsintegrates security into the DevOps culture and CI/CD pipelines. Instead of treating security as an afterthought, DevSecOps ensures security checks, policies, and automated validations are embedded throughout the CI/CD process.
"DevSecOps emphasizes shifting security left, integrating security testing, validation, and compliance into every stage of the CI/CD pipeline. This ensures vulnerabilities are detected early and software is delivered securely." Thus,Dis correct: DevSecOps culture is essential for CI/CD pipelines to ensure security is baked into software delivery.
References:GitOps Related Practices (CNCF GitOps Working Group), DevSecOps in CI/CD.
NEW QUESTION # 41
In GitOps, what is a pull-based approach?
- A. A pull-based approach is when the GitOps system continuously polls the Git repository for changes and applies them automatically.
- B. A pull-based approach is when the GitOps system sends notifications to developers to apply changes from the Git repository manually.
- C. A pull-based approach is when developers manually push changes to the GitOps system, which then applies them automatically.
- D. A pull-based approach is when the Git repository automatically pushes changes to the GitOps system, which then applies them.
Answer: A
Explanation:
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.
References:GitOps Principles (CNCF GitOps Working Group), Pull-based Reconciliation Model.

- A. Configuring a CI/CD pipeline to build and deploy the application to the Kubernetes cluster automatically.
- B. Creating a Helm chart to define the application's configuration and dependencies.
- C. Creating a well-formatted script to deploy the application to the Kubernetes cluster.
- D. Writing a Dockerfile to build a container image of the application and configuration.
Answer: B
Explanation:
Helm is a Kubernetes package manager widely used in GitOps for packaging, configuring, and deploying complex applications. Helm charts bundle configuration, dependencies, and Kubernetes manifests into reusable, declarative packages that can be applied across multiple clusters.
"Helm charts provide a way to package Kubernetes applications, defining configuration and dependencies declaratively. This allows consistent deployment across clusters in GitOps workflows." Thus, the correct answer isA.
