NEW QUESTION # 37
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 new version of the application is deployed first, followed by the old version.
- B. The Blue-Green deployment pattern only deploys single versions of the application.
- C. The old version of the application is deployed first, followed by the new version.
- D. Both the new and old versions of the application are deployed simultaneously.
Answer: D
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 # 38
What is Infrastructure as Code (IaC)?
- A. A programming approach to managing and provisioning infrastructure resources through machine- readable definition files
- B. A methodology for managing infrastructure resources through graphical user interfaces
- C. An approach to managing infrastructure resources using physical hardware only
- D. A manual process of managing infrastructure resources using the command line
Answer: A
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.

NEW QUESTION # 39
In GitOps, which option describesState Storemanagement?
- A. Storing state information in a distributed file system.
- B. Storing state information in a version control system.
- C. Storing state information in a centralized database.
- D. Storing state information in a relational database.
Answer: B
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 # 40
Which GitOps tool has the option for a push-based reconciliation model?
- A. ArgoCD
- B. Flux
- C. Argo Workflows
- D. Flagger
Answer: A
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 # 41
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 # 42
In the context of GitOps, why would you do a rollback?
- A. To improve performance and optimize resource utilization.
- B. To undo a deployment that introduced a critical bug or caused a system failure.
- C. To create a backup of the current configuration.
- D. To test a new feature in a controlled environment.
Answer: B
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 # 43
Which of the following statements accurately describes the role of GitOps in progressive delivery?
- A. GitOps requires end users to manually shift traffic for progressive delivery.
- B. GitOps only works with manual progressive delivery without any automation.
- C. GitOps allows end users to perform progressive delivery automatically without manually shifting traffic.
- D. GitOps does not allow end users to perform progressive delivery automatically, only manually.
Answer: C
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 # 44
Which method(s) of accessing the Desired State store does GitOps support?
- A. Push method only
- B. Replication only
- C. Neither push nor pull
- D. Pull is required and push can optionally be used in addition to pull
Answer: D
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 # 45
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. Adjust the reconcile process interval time.
- C. Manually execute a script to initiate the reconcile process on the cluster using GitOps tool CLI commands.
- D. Schedule a cron job to run the reconcile process periodically, using RBAC to authenticate.
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 # 46
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. Prometheus
- D. Jenkins X
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 # 47
In a GitOps-managed workflow, what is the correct way to initiate rollback?
- A. Revert to an older version and force push to the main branch.
- B. Create a new version based on a former version so you always "roll forward".
- C. Overwrite your existing version with the code from your last working version.
- D. Use Helm to rollback to a previous release version.
Answer: B
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 # 48
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 # 49
In the context of GitOps, what doesContinuousmean?
- A. Reconciliation must happen instantaneously.
- B. Reconciliation happens only during instantiation.
- C. Reconciliation continues to happen.
- D. Reconciliation only happens once.
Answer: C
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 # 50
Which statement describes Blue-Green deployments?
- A. 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.
- B. Blue-Green deployments involve deploying different versions of an application in other regions and routing traffic based on geographic location.
- C. Blue-Green deployments involve deploying the new version of an application to a subset of users and gradually expanding the deployment based on feedback.
- D. Blue-Green deployments involve deploying only one version at a time.
Answer: A
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 # 51
What doesPulled Automaticallyrefer to?
- A. Webhooks informing the system about new commits.
- B. It always refers to Git pull.
- 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 # 52
What does the GitOps reconciliation loop ensure?
- A. That the Desired State is instantaneously applied to the system.
- B. The Desired State is applied to the system when the current system state diverges from the Desired State.
- C. When manifests have errors, it will ensure that as much as possible still gets applied.
- D. Only applies changes but does not remove resources that used to be part of the Desired State.
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 # 53
You want to create a dashboard to monitor the performance of your application. Which of the following is a key principle of GitOps regarding dashboards?
- A. The operations team should manually update dashboards.
- B. Dashboards should be created using a proprietary tool.
- C. Dashboards should only be accessible to the development team.
- D. Dashboards declarations should be in the Desired State store.
Answer: D
Explanation:
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.
References:GitOps Principles (CNCF GitOps Working Group).
NEW QUESTION # 54
How does GitOps handle drift during reconciliation?
- A. Attempt to apply Desired State to the running system.
- B. Find the differences between Desired State and actual state and create a new system based on these changes.
- C. Write back to Desired State to match the actual state.
- D. Write Kubernetes Patch files in a database for later use.
Answer: A
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.
