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
  • 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 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
  • 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.
Topic 5
  • 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.

Linux Foundation Certified GitOps Associate Sample Questions (Q42-Q47):NEW QUESTION # 42
Which of these Git commands will enact a rollback of the configuration to a previous commit?
  • A. git commit
  • B. git push
  • C. git branch
  • D. git revert
Answer: D
Explanation:
In GitOps, rollback is performed by reverting the system'sDesired Statestored in Git. This is done with thegit revertcommand, which creates a new commit that undoes the changes introduced by a previous commit.
"Because Git provides an immutable history of changes, rollbacks are straightforward. Reverting to a previous configuration is accomplished by reverting the commit in Git, which then allows the reconciler to apply the earlier desired state." Thus, the correct answer isB: git revert.

NEW QUESTION # 43
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. When only events trigger reconciliation, the system is more vulnerable to drift caused by other things.
  • B. Pull-based systems are more efficient in handling real-time events.
  • C. Pull-based systems require a constant network connection to receive updates.
  • D. Event-driven systems are less flexible and scalable compared to pull-based systems.
Answer: A
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 # 44
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. Raise a ticket with the development team to fix the error in the configuration file.
  • B. Make a call to the Kubernetes API with the correction.
  • C. Continue to monitor the issue and proceed with the deployment, as it may not significantly impact the application.
  • 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 # 45
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 version of Kubernetes and the availability of network resources.
  • D. The size of the cluster and the complexity of the reconciler logic.
Answer: D
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.

NEW QUESTION # 46
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 have conflicting functionalities.
  • B. If you modify their source code, ArgoCD and Flux can only be used together.
  • C. ArgoCD and Flux can be used together, leveraging a drop-in extension for ArgoCD, ensuring that both reconciliation engines do not conflict.
  • D. ArgoCD and Flux cannot be used together as they are designed for different types of deployments.
Answer: C
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.
