NEW QUESTION # 35
You are deploying a new version of your application using the Blue-Green deployment pattern. What is a characteristic of the Blue-Green deployment pattern?
- A. The old version of the application is deployed first, followed by the new version.
- B. Both the new and old versions of the application are deployed simultaneously.
- C. The Blue-Green deployment pattern only deploys single versions of the application.
- D. The new version of the application is deployed first, followed by the old version.
Answer: B
Explanation:
In aBlue-Green deployment, two environments (Blue and Green) exist at the same time. The current version runs in one environment (Blue), and the new version is deployed to the other environment (Green). Traffic is switched to Green once the new version is validated.
"Blue-Green deployments maintain two production environments. The new version is deployed alongside the old version, and once validated, traffic is switched from Blue to Green." Thus, the correct answer isC.

NEW QUESTION # 36
In GitOps, what does the principle ofVersioned and Immutablemean?
- A. All software versions should be stored in a Git repository.
- B. Configuration and infrastructure code should be modified directly on production environments.
- C. All changes to configuration and infrastructure should be made directly on production environments.
- D. Configuration and infrastructure code should be version-controlled and treated as immutable artifacts.
Answer: D
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 # 37
When using Kustomize, how are resources, configurations, and customizations commonly organized?
- A. In separate configuration files for each resource.
- B. By specifying all resources inline in the customization file.
- C. Using a combination of folder directories and referenced folder/file paths.
- D. In a single configuration file.
Answer: C
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 # 38
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. Manually execute a script to initiate the reconcile process on the cluster using GitOps tool CLI commands.
- B. Schedule a cron job to run the reconcile process periodically, using RBAC to authenticate.
- C. Use a webhook to trigger the reconcile process based on events or changes in the Git repository.
- D. Adjust the reconcile process interval time.
Answer: C
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 # 39
Which of these is an advantage of using a declarative configuration for your Desired State?
- A. Using widely adopted community tools for reconciling actual state is less work than maintaining custom imperative scripts.
- B. Declarative configuration allows you to execute code locally more efficiently to make desired changes to your running system.
- C. Declarative configuration helps you include dynamic scripting that guides an application through a step- by-step process.
- D. Declarative configuration lets you specify complex if/else logic within custom code.
Answer: A
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 # 40
You are working on a GitOps project and want to ensure that the configuration files are written in a standardized format. What is the recommended way to ensure this?
- A. Ignore the formatting issues and focus on the functionality of the configuration files.
- B. Use a linter tool to automatically check the configuration files for formatting issues.
- C. Manually review each configuration file to check for any formatting issues.
- D. Ask team members to manually review each other's configuration files for formatting issues.
Answer: B
Explanation:
Linting tools are essential in GitOps practices for maintaining consistency, standardization, and quality in configuration files. Automated linters can validate YAML manifests, Helm charts, or Kustomize overlays for formatting and best practices.
"Linters automate the enforcement of formatting and quality rules in declarative configuration files. They ensure standardized structure and reduce errors in GitOps workflows." Thus, the correct answer isC.
References:GitOps Related Practices (CNCF GitOps Working Group).
NEW QUESTION # 41
How does GitOps handle drift during reconciliation?
- A. Write Kubernetes Patch files in a database for later use.
- B. Write back to Desired State to match the actual state.
- C. Attempt to apply Desired State to the running system.
- D. Find the differences between Desired State and actual state and create a new system based on these changes.
Answer: C
Explanation:
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.
NEW QUESTION # 42
What doesPulled Automaticallyrefer to?
- A. It always refers to Git pull.
- B. A GET request to a relational database.
- C. Accessing the Desired State from the State Store.
- D. Webhooks informing the system about new commits.
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 # 43
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. Roll back the deployment to the previous working version while investigating the error in the configuration file.
- D. Raise a ticket with the development team to fix the error in the configuration file.
Answer: C
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 # 44
Which two GitOps controllers are the most popular?
- A. Jenkins and Tekton
- B. Keptn and Puppet
- C. Helm and Kustomize
- D. ArgoCD and Flux
Answer: D
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 # 45
What is Infrastructure as Code (IaC)?
- A. An approach to managing infrastructure resources using physical hardware only
- B. A manual process of managing infrastructure resources using the command line
- C. A methodology for managing infrastructure resources through graphical user interfaces
- D. A programming approach to managing and provisioning infrastructure resources through machine- readable definition files
Answer: D
Explanation:
Infrastructure as Code (IaC)is a foundational practice in GitOps. It involves managing and provisioning infrastructure throughdeclarative, machine-readable filesrather than manual processes or GUIs. IaC ensures consistency, automation, and repeatability across environments.
"Infrastructure as Code defines and manages infrastructure through code files stored in version control. This enables automation, reproducibility, and immutability in infrastructure provisioning." Thus,Dis correct.
References:GitOps Related Practices (CNCF GitOps Working Group).
NEW QUESTION # 46
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 # 47
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, DevSecOps focuses only on security outside of CI/CD pipelines.
- C. No, because CI/CD systems are totally secure by design.
- D. No, because CI/CD systems are incompatible with the DevSecOps culture.
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.
References:GitOps Related Practices (CNCF GitOps Working Group), DevSecOps in CI/CD.
NEW QUESTION # 48
In GitOps, which option describesState Storemanagement?
- A. Storing state information in a version control system.
- B. Storing state information in a relational database.
- C. Storing state information in a distributed file system.
- D. Storing state information in a centralized database.
Answer: A
Explanation:
TheState Storeis typically implemented using aversion control system (VCS)such as Git. This ensures that the system's state is auditable, versioned, and immutable. Other systems like databases or distributed file systems do not meet the immutability and versioning requirements of GitOps.
"In GitOps, the desired state must be stored in a version control system. This serves as the State Store, providing a complete, immutable, and auditable history of changes." Thus, the correct answer isD: version control system.
References:GitOps Terminology (CNCF GitOps Working Group).
NEW QUESTION # 49
In GitOps, what is a pull-based approach?
- A. A pull-based approach is when developers manually push changes to the GitOps system, which then 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 the Git repository automatically pushes changes to the GitOps system, which then applies them.
- D. A pull-based approach is when the GitOps system continuously polls the Git repository for changes and applies them automatically.
Answer: D
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.
NEW QUESTION # 50
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 two completely separate concepts with no relation to each other.
- C. DevOps and GitOps are interchangeable terms used to describe the same concept and principles.
- D. DevOps and GitOps are competing methodologies, and organizations must choose one over the other.
Answer: A
Explanation:
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).
NEW QUESTION # 51
In the context of GitOps, what source of truth guides the continuous deployment process?
- A. Fleeting State
- B. Current State
- C. Desired State
- D. Dynamic State
Answer: C
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 # 52
In the context of GitOps, what doesContinuousmean?
- A. Reconciliation continues to happen.
- B. Reconciliation must happen instantaneously.
- C. Reconciliation happens only during instantiation.
- D. Reconciliation only happens once.
Answer: A
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.
References:GitOps Principles (CNCF GitOps Working Group),Principle 4: Continuously reconciled.
NEW QUESTION # 53
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. 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. 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 # 54
Which method(s) of accessing the Desired State store does GitOps support?
- A. Replication only
- B. Push method only
- C. Pull is required and push can optionally be used in addition to pull
- D. Neither push nor pull
Answer: C
Explanation:
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.
References:GitOps Principles (CNCF GitOps Working Group), Reconciliation Models.
NEW QUESTION # 55
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.
References:GitOps Principles (CNCF GitOps Working Group), Rollback and Recovery Practices.
NEW QUESTION # 56
You want to route alerts from Prometheus to Slack in your GitOps workflow. Which tool can you use to achieve this?
- A. Alertmanager
- B. Slack
- C. Jenkins X
- D. Prometheus
Answer: A
Explanation:
Prometheus is commonly used in GitOps for monitoring.Alertmanageris the tool integrated with Prometheus to handle alert routing. It supports sending alerts to external systems such as Slack, PagerDuty, or email.
"Prometheus generates alerts, which are routed and managed by Alertmanager. Alertmanager can integrate with messaging tools like Slack to deliver alerts in real time." Thus, the correct answer isA: Alertmanager.
References:GitOps Tooling (CNCF GitOps Working Group), Monitoring and Alerting practices.
NEW QUESTION # 57
You want to deploy an application using GitOps. Which of the following steps should be included in the deployment process?
- A. Skipping the deployment process and directly running the application code.
- B. Committing the deployment configuration to a Git repository or similar State Store.
- C. Running a script in CI to deploy the application.
- D. Manually copying the application code to the production server.
Answer: B
Explanation:
In GitOps, deployments are driven bycommitting declarative configurationinto a Git repository (the State Store). From there, agents reconcile the actual environment to match the desired state, making deployments reproducible and auditable.
"To deploy in GitOps, commit the declarative configuration into version control. The reconciler ensures the runtime environment converges to the declared state." Thus, the correct answer isD.
References:GitOps Principles (CNCF GitOps Working Group),Principle 1: Declarative configuration stored in Git.
