質問 # 30
What doesPulled Automaticallyrefer to?
- A. Accessing the Desired State from the State Store.
- B. A GET request to a relational database.
- C. It always refers to Git pull.
- D. Webhooks informing the system about new commits.
正解：A
解説：
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.

質問 # 31
In the context of GitOps, what happens to a GitOps-managed Kubernetes cluster if there is drift divergence?
- A. The GitOps-managed Kubernetes cluster automatically reconciles the drift divergence to return the cluster to the Desired State.
- B. The GitOps-managed Kubernetes cluster rolls back to the previous known state before the drift divergence occurred.
- C. The GitOps-managed Kubernetes cluster ignores the drift divergence and continues to operate as it is.
- D. The GitOps-managed Kubernetes cluster notifies the administrator about the drift divergence and waits for manual intervention.
正解：A
解説：
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.
References: GitOps Principles (CNCF GitOps Working Group), GitOps Principles Document -Principle 4:
Software agents automatically pull the desired state declarations from the source and continuously observe actual system state, reconciling differences.
質問 # 32
Why is the feedback loop important for reconciliation?
- A. To trigger an alert if a change is detected, and log the event to the log aggregation service.
- B. To analyze state-sync logging information and perform a sync.
- C. Feedback loop is not important for reconciliation.
- D. To determine if a reconciliation is needed and whether a sync should be partial or complete.
正解：D
解説：
Thefeedback loopis critical in GitOps reconciliation. It continuously monitors the system's actual state and compares it to the desired state. This loop determines when reconciliation is required and whether a full or partial synchronization is necessary.
"The feedback loop in reconciliation continuously observes the actual state. It determines if reconciliation is required, and informs whether to perform a partial or full sync to align with the declared desired state." Thus, the correct answer isA.
References:GitOps Related Practices (CNCF GitOps Working Group), Reconciliation Feedback Loops.
質問 # 33
What is one of the key benefits of a pull-based reconciliation approach to configuration management?
- A. Immediate response time to configuration changes.
- B. Simplified troubleshooting and debugging processes.
- C. Agents can access the Desired State at any time, not only when an event is triggered.
- D. The CI has access credentials to the running system.
正解：C
解説：
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.
質問 # 34
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 only works with manual progressive delivery without any automation.
- C. GitOps does not allow end users to perform progressive delivery automatically, only manually.
- D. GitOps requires end users to manually shift traffic for progressive delivery.
正解：A
解説：
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.
質問 # 35
What is the main difference between Terraform/OpenTofu and Ansible?
- A. Ansible is written in Golang, while Terraform/OpenTofu is written in Python.
- B. Terraform/OpenTofu stores the state of each resource, while Ansible works in a fire-and-forget mode.
- C. Terraform/OpenTofu uses a configuration language called CUE, while Ansible uses HCL.
- D. Terraform/OpenTofu is imperative in nature, while Ansible is declarative.
正解：B
解説：
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.
References:GitOps Tooling (CNCF GitOps Working Group).
質問 # 36
You are packaging a complex application to deploy to multiple Kubernetes clusters using GitOps. Which of the following would be a suitable solution for this process?
- A. Creating a Helm chart to define the application's configuration and dependencies.
- B. Writing a Dockerfile to build a container image of the application and configuration.
- C. Configuring a CI/CD pipeline to build and deploy the application to the Kubernetes cluster automatically.
- D. Creating a well-formatted script to deploy the application to the Kubernetes cluster.
正解：A
解説：
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.
References:GitOps Tooling (CNCF GitOps Working Group), Helm usage in GitOps.
質問 # 37
In the context of GitOps, which of the following is the primary purpose of Desired State?
- A. To store all persistent application data, such as database content.
- B. To serve as a blueprint to recreate a system for behavioral consistency.
- C. For monitoring real-time application performance.
- D. To track code changes that developers have made.
正解：B
解説：
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.
References:GitOps Terminology (CNCF GitOps Working Group).
質問 # 38
In the context of GitOps, why would you do a rollback?
- A. To test a new feature in a controlled environment.
- B. To create a backup of the current configuration.
- C. To improve performance and optimize resource utilization.
- D. To undo a deployment that introduced a critical bug or caused a system failure.
正解：D
解説：
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.
References:GitOps Principles (CNCF GitOps Working Group), Rollback and Recovery.
質問 # 39
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. Schedule a cron job to run the reconcile process periodically, using RBAC to authenticate.
- B. Adjust the reconcile process interval time.
- C. Use a webhook to trigger the reconcile process based on events or changes in the Git repository.
- D. Manually execute a script to initiate the reconcile process on the cluster using GitOps tool CLI commands.
正解：C
解説：
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.
質問 # 40
In GitOps, how is the Desired State stored?
- A. In a way that enforces mutability and versioning.
- B. In a way that retains only the latest version.
- C. In a way that enforces immutability and versioning.
- D. In a way that permits direct modifications to live systems.
正解：C
解説：
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).
質問 # 41
In GitOps, what is the process of ensuring the actual state of a system matches its Desired State called?
- A. Manual Intervention
- B. Webhooks
- C. Reconciliation
- D. Monitoring
正解：C
解説：
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).
質問 # 42
In the context of GitOps, what is the purpose of a State Store?
- A. To provide a system for storing the current state of an application.
- B. To provide a system for storing mutable versions of Desired State declarations.
- C. To provide a system for storing immutable versions of Desired State declarations.
- D. To provide a system for storing temporary state data during GitOps deployments.
正解：C
解説：
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.
References:GitOps Terminology (CNCF GitOps Working Group).
質問 # 43
How does GitOps handle drift during reconciliation?
- A. Find the differences between Desired State and actual state and create a new system based on these changes.
- B. Attempt to apply Desired State to the running system.
- C. Write Kubernetes Patch files in a database for later use.
- D. Write back to Desired State to match the actual state.
正解：B
解説：
Whendriftoccurs (actual state diverges from desired state), GitOps controllers attempt to reapply theDesired Statestored in Git. The system is always converged toward what Git declares, never the other way around.
"In case of drift, the reconciler re-applies the desired state from Git to the runtime environment, ensuring the actual system matches the declared configuration." Thus, the correct answer isB.
References:GitOps Principles (CNCF GitOps Working Group), Drift Management.
質問 # 44
Which GitOps tool has the option for a push-based reconciliation model?
- A. ArgoCD
- B. Flagger
- C. Argo Workflows
- D. Flux
正解：A
解説：
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.
質問 # 45
Which of the following statements best describes the relationship between DevOps and GitOps?
- A. GitOps is a set of principles to guide modern DevOps in practice.
- B. DevOps and GitOps are interchangeable terms used to describe the same concept and principles.
- C. DevOps and GitOps are competing methodologies, and organizations must choose one over the other.
- D. DevOps and GitOps are two completely separate concepts with no relation to each other.
正解：A
解説：
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.
References:GitOps Related Practices (CNCF GitOps Working Group).
質問 # 46
In a GitOps framework, what distinct advantage does Configuration as Code (CaC) provide in comparison to traditional infrastructure management approaches?
- A. GitOps leverages CaC for immutable infrastructure deployments, ensuring consistent environments, unlike traditional methods that allow ad-hoc changes.
- B. In GitOps, CaC enables dynamic resource allocation during runtime, contrasting with the static configurations in traditional methods.
- C. CaC in GitOps exclusively automates the documentation process, whereas traditional approaches focus on manual documentation.
- D. CaC is less secure and more complex than traditional infrastructure management.
正解：A
解説：
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.
References:GitOps Related Practices (CNCF GitOps Working Group).
質問 # 47
In the context of GitOps, what doesContinuousmean?
- A. Reconciliation must happen instantaneously.
- B. Reconciliation continues to happen.
- C. Reconciliation only happens once.
- D. Reconciliation happens only during instantiation.
正解：B
解説：
One of the four core GitOps principles is that the system must beContinuously Reconciled. This means reconciliation is not a one-time or on-demand process but happensconstantlyin the background, ensuring the actual system state remains aligned with the declared desired state.
"GitOps requires that reconciliation is continuous. Software agents continuously compare actual state against desired state and automatically reconcile differences." Thus, the correct answer isC.
References:GitOps Principles (CNCF GitOps Working Group),Principle 4: Continuously reconciled.
質問 # 48
In GitOps practices, when does CD take part?
- A. CD takes part simultaneously with CI, both components of GitOps practices.
- B. CD takes part before CI stage in order to ensure the successful deployment of applications.
- C. CI plays a significant role in GitOps practices.
- D. CD takes part after CI to automate the deployment of applications based on changes in the Git repository.
正解：D
解説：
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.
References: GitOps Principles (CNCF GitOps Working Group), GitOps Working Group Terminology & Principles documents.
質問 # 49
Would you implement DevSecOps culture in CI/CD pipelines?
- A. No, because CI/CD systems are incompatible with the DevSecOps culture.
- B. No, because CI/CD systems are totally secure by design.
- C. Yes, DevSecOps is essential for CI/CD pipelines. It helps build software without any security issues.
- D. No, DevSecOps focuses only on security outside of CI/CD pipelines.
正解：C
解説：
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.
質問 # 50
Which requirement of the GitOps principle declares that Desired State must be versioned?
- A. The State Store must retain a complete version history.
- B. The Desired State must not be publicly accessible.
- C. The Desired State must be publicly accessible.
- D. You must use Git in order to be compliant with this principle.
正解：A
解説：
One of the GitOps principles isVersioned and Immutable, which requires that the Desired State is stored in a system that maintains acomplete version history. This allows for auditing, traceability, and rollback.
"The Desired State must be stored in a versioned, immutable system. The State Store must retain a complete version history so changes can be audited and previous states can be restored." Thus, the correct answer isB.
References:GitOps Principles (CNCF GitOps Working Group),Principle 2: Versioned and Immutable.
