NEW QUESTION # 16
Would you implement DevSecOps culture in CI/CD pipelines?
- A. Yes, DevSecOps is essential for CI/CD pipelines. It helps build software without any security issues.
- B. No, because CI/CD systems are incompatible with the DevSecOps culture.
- C. No, because CI/CD systems are totally secure by design.
- D. No, DevSecOps focuses only on security outside of CI/CD pipelines.
Answer: A
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.

NEW QUESTION # 17
In the context of GitOps, what source of truth guides the continuous deployment process?
- A. Current State
- B. Fleeting State
- C. Dynamic State
- D. Desired State
Answer: D
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 # 18
In GitOps, how is the Desired State stored?
- A. In a way that retains only the latest version.
- B. In a way that enforces immutability and versioning.
- C. In a way that permits direct modifications to live systems.
- D. In a way that enforces mutability and versioning.
Answer: B
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 # 19
How can you achieve the declarative GitOps principle in managing infrastructure and applications?
- A. By defining and maintaining infrastructure and application configurations declaratively in a version- controlled system.
- B. By manually making ad-hoc configuration changes directly in the production environment.
- C. By periodically creating manual backups of your infrastructure configurations.
- D. By using imperative scripting languages to automate infrastructure changes.
Answer: A
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 # 20
Which two GitOps controllers are the most popular?
- A. Helm and Kustomize
- B. ArgoCD and Flux
- C. Keptn and Puppet
- D. Jenkins and Tekton
Answer: B
Explanation:
The two most widely adopted GitOps controllers in the CNCF ecosystem areArgoCDandFlux. Both implement the GitOps principles of continuous reconciliation from Git as the source of truth.
"ArgoCD and Flux are the two primary CNCF GitOps controllers. They implement reconciliation loops to ensure the desired state in Git matches the cluster's actual state." Thus, the correct answer isC.
References:GitOps Tooling (CNCF GitOps Working Group).
NEW QUESTION # 21
Which deployment and release pattern involves gradually shifting traffic from an old version of an application to a new one?
- A. Canary Deployment
- B. A/B Deployment
- C. Blue-Green Deployment
- D. Red/Black 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.
References:GitOps Patterns (CNCF GitOps Working Group), Progressive Delivery.
NEW QUESTION # 22
You are working on a GitOps project and have made some changes to the cluster using kubectl. What is the recommended approach to ensure that your changes are continuously reconciled?
- A. Save those changes to the Desired State store and allow the GitOps controller to attempt reconciliation.
- B. Reconcile the changes by running a script or command that synchronizes the cluster with the desired state.
- C. Delete and recreate the cluster from scratch to ensure a clean and controlled state.
- D. Use kubectl to delete all resources that were changed in the cluster and wait for a reconcile.
Answer: A
Explanation:
In GitOps,Git is the single source of truth. If changes are made manually in the cluster (viakubectl), those changes will drift from the desired state in Git. To ensure consistency, the correct approach is toupdate the Git repository (Desired State store)so that the reconciler can continuously apply and maintain those changes.
"The desired state must always be declared in Git. Manual changes in the cluster will be overwritten by reconciliation unless they are committed to the Git repository." Thus, the correct answer isB.
References:GitOps Principles (CNCF GitOps Working Group), Drift and Reconciliation Practices.
NEW QUESTION # 23
You are implementing GitOps in your organization and have configured the Desired State of your applications in a Git repository. However, during the deployment process, you encounter an error in the configuration. What is the recommended action in this scenario?
- A. Make a call to the Kubernetes API with the correction.
- B. Continue to monitor the issue and proceed with the deployment, as it may not significantly impact the application.
- C. Raise a ticket with the development team to fix the error in the configuration file.
- D. Roll back the deployment to the previous working version while investigating the error in the configuration file.
Answer: D
Explanation:
GitOps emphasizes immutability and auditability. If an error occurs in the configuration stored in Git, the system should be rolled back to the last known good state while the error is fixed. This preserves system reliability and aligns with the GitOps principle of rollback through version control.
"With Git as the source of truth, if an error is introduced, the system can be rolled back by reverting to a previous commit. This ensures stability while the faulty configuration is corrected." Thus, the recommended action isC: Roll back to the previous working version.
References:GitOps Principles (CNCF GitOps Working Group).
NEW QUESTION # 24
Which of these is an advantage of using a declarative configuration for your Desired State?
- A. Declarative configuration helps you include dynamic scripting that guides an application through a step- by-step process.
- B. Declarative configuration allows you to execute code locally more efficiently to make desired changes to your running system.
- C. Declarative configuration lets you specify complex if/else logic within custom code.
- D. Using widely adopted community tools for reconciling actual state is less work than maintaining custom imperative scripts.
Answer: D
Explanation:
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.
References:GitOps Principles (CNCF GitOps Working Group), Declarative Systems.
NEW QUESTION # 25
You are working on a GitOps deployment and want to manage the configuration of your Kubernetes resources across multiple environments. How does Kustomize help?
- A. Kustomize helps you create and manage Kubernetes resource manifests by providing a graphical user interface (GUI).
- B. Kustomize helps you create and manage Kubernetes resource manifests by providing a way to customize them through patching.
- C. Kustomize allows you to package and distribute your application as a Helm chart.
- D. Kustomize is a tool for deploying infrastructure resources using Terraform/OpenTofu.
Answer: B
Explanation:
Kustomizeis a Kubernetes-native configuration management tool that allows manifest customization without modifying the original YAML files. It uses overlays and patches to adapt configurations for different environments.
"Kustomize provides a declarative way to customize Kubernetes manifests by applying patches and overlays.
This allows managing multiple environments without duplicating manifest files." Thus, the correct answer isD.
References:GitOps Tooling (CNCF GitOps Working Group), Kustomize.
NEW QUESTION # 26
In GitOps, what does it mean toContinuously Reconcile?
- A. Perform regular backups of Git repositories.
- B. Monitor the system for any unauthorized changes and revert them.
- C. Automatically compare and adjust the system state as needed.
- D. Regularly update Git repositories with the latest changes from external sources.
Answer: C
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 # 27
When deciding whether to use an in-cluster reconciler or an external reconciler, what factors should be considered?
- A. The location of the state store and the number of replicas.
- B. The programming language the applications are written in.
- C. The size of the cluster and the complexity of the reconciler logic.
- D. The version of Kubernetes and the availability of network resources.
Answer: C
Explanation:
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.
References:GitOps Related Practices (CNCF GitOps Working Group), GitOps Reconciler Guidelines.
NEW QUESTION # 28
In GitOps, what does the principle ofVersioned and Immutablemean?
- A. Configuration and infrastructure code should be modified directly on production environments.
- B. All software versions should be stored in a Git repository.
- C. Configuration and infrastructure code should be version-controlled and treated as immutable artifacts.
- D. All changes to configuration and infrastructure should be made directly on production environments.
Answer: C
Explanation:
One of the four fundamental GitOps principles isVersioned and Immutable. This means that the entire system' s desired state must be stored in a Git repository with version control. Each change must be represented as a commit, and Git's immutability guarantees a reliable, auditable history of how the system evolved.
"The desired state is stored in a version control system. The record of truth is stored in an immutable history, and changes can be audited and reverted if necessary. This guarantees that the system's configuration is versioned, immutable, and traceable." Thus,configuration and infrastructure must be version-controlled and immutable, never changed directly in production.
References:GitOps Principles (CNCF GitOps Working Group),Principle 2: The desired system state is stored as versioned and immutable.
NEW QUESTION # 29
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. Pull-based systems require a constant network connection to receive updates.
- B. Pull-based systems are more efficient in handling real-time events.
- C. Event-driven systems are less flexible and scalable compared to pull-based systems.
- D. When only events trigger reconciliation, the system is more vulnerable to drift caused by other things.
Answer: D
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 # 30
In a GitOps-managed workflow, what is the correct way to initiate rollback?
- A. Overwrite your existing version with the code from your last working version.
- B. Revert to an older version and force push to the main branch.
- C. Use Helm to rollback to a previous release version.
- D. Create a new version based on a former version so you always "roll forward".
Answer: D
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.
References:GitOps Principles (CNCF GitOps Working Group), Rollback and Recovery Practices.
NEW QUESTION # 31
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 undo a deployment that introduced a critical bug or caused a system failure.
- D. To improve performance and optimize resource utilization.
Answer: C
Explanation:
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.
NEW QUESTION # 32
In GitOps, how are the Desired State declarations pulled from the source?
- A. Manually triggered by a webhook.
- B. With a CLI command or API call.
- C. By sending a request to the source repository.
- D. Automatically by software agents.
Answer: D
Explanation:
A fundamental GitOps principle is that reconciliation isautomated and continuous. Software agents (e.g., controllers like ArgoCD or Flux) continuously pull desired state declarations from Git repositories and reconcile them with the actual state.
"Software agents automatically pull the desired state declarations from the source of truth and continuously reconcile the actual state to match." Thus, the correct answer isC.
References:GitOps Principles (CNCF GitOps Working Group),Principle 4: Continuously reconciled.
NEW QUESTION # 33
In the context of GitOps, what doesContinuousmean?
- A. Reconciliation only happens once.
- B. Reconciliation must happen instantaneously.
- C. Reconciliation happens only during instantiation.
- D. Reconciliation continues to happen.
Answer: D
Explanation:
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.
