As the captioned description said, our CGOA practice materials are filled with the newest points of knowledge about the exam. With many years of experience in this line, we not only compile real test content into our CGOA learning quiz, but the newest in to them. And our professionals always keep a close eye on the new changes of the subject and keep updating the CGOA study questions to the most accurate.
Though there are three versions of our CGOA exam braindumps: the PDF, Software and APP online. When using the APP version for the first time, you need to ensure that the network is unblocked, and then our CGOA guide questions will be automatically cached. The network is no longer needed the next time you use it. You can choose any version of our CGOA Practice Engine that best suits your situation. It's all for you to learn better.
Linux Foundation CGOA Exam Actual Questions & Valid Exam CGOA BraindumpsAt present, our CGOA exam guide gains popularity in the market. The quality of our CGOA training material is excellent. After all, we have undergone about ten years’ development. Never has our practice test let customers down. Although we also face many challenges and troubles, our company get over them successfully. If you are determined to learn some useful skills, our CGOA Real Dumps will be your good assistant. Then you will seize the good chance rather than others.
Linux Foundation CGOA Exam Syllabus Topics:
TopicDetails
Topic 1
  • GitOps Principles: This section of the exam measures skills of Site Reliability Engineers and covers the main principles of GitOps, such as being declarative, versioned and immutable, automatically pulled, and continuously reconciled.
Topic 2
  • GitOps Terminology: This section of the exam measures the skills of DevOps Engineers and covers the foundational terms of GitOps, including declarative descriptions, desired state, state drift, reconciliation, managed systems, state stores, feedback loops, and rollback concepts.
Topic 3
  • Tooling: This section of the exam measures skills of DevOps Engineers and covers the tools supporting GitOps, including manifest formats, packaging methods, state store systems such as Git and alternatives, reconciliation engines like ArgoCD and Flux, and interoperability with CI, observability, and notification tools.
Topic 4
  • Related Practices: This section of the exam measures the skills of DevOps Engineers and covers how GitOps relates to broader practices like configuration as code, infrastructure as code, DevOps, and DevSecOps, along with continuous integration and delivery.
Topic 5
  • GitOps Patterns: This section of the exam measures skills of Site Reliability Engineers and covers deployment and release patterns, progressive delivery, pull versus event-driven approaches, and various architectural patterns for in-cluster and external reconcilers.

Linux Foundation Certified GitOps Associate Sample Questions (Q26-Q31):NEW QUESTION # 26
Which two GitOps controllers are the most popular?
  • A. Helm and Kustomize
  • B. Jenkins and Tekton
  • C. Keptn and Puppet
  • 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 # 27
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. When only events trigger reconciliation, the system is more vulnerable to drift caused by other things.
  • C. Event-driven systems are less flexible and scalable compared to pull-based systems.
  • D. Pull-based systems are more efficient in handling real-time events.
Answer: B
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 # 28
Which method(s) of accessing the Desired State store does GitOps support?
  • A. Replication only
  • B. Neither push nor pull
  • C. Pull is required and push can optionally be used in addition to pull
  • D. Push method only
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 # 29
In GitOps practices, when does CD take part?
  • A. CD takes part simultaneously with CI, both components of GitOps practices.
  • B. CI plays a significant role in GitOps practices.
  • C. CD takes part before CI stage in order to ensure the successful deployment of applications.
  • 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 # 30
A GitOps project wants to leverage both ArgoCD and Flux for a deployment. Can ArgoCD and Flux be used in conjunction?
  • A. ArgoCD and Flux cannot be used together as they are designed for different types of deployments.
  • 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 have conflicting functionalities.
  • D. If you modify their source code, ArgoCD and Flux can only be used together.
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.
