- Topic 1: 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 2: 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 3: 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 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: 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.

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?
In GitOps, the pull-based model continuously reconciles the actual state with the desired state. This makes it resilient to drift, since reconciliation runs regularly. In contrast, event-driven systems only 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 is D.
===========
Which GitOps tool has the option for a push-based reconciliation model?
Most GitOps tools (e.g., Flux) are pull-based only. However, ArgoCD supports both pull-based reconciliation (via continuous monitoring) and an optional push-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 is A: ArgoCD.

Thus, the correct answer is D.
===========
In the context of GitOps, what source of truth guides the continuous deployment process?
The Desired 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 is A.
===========
You want to deploy an application using GitOps. Which of the following steps should be included in the deployment process?
In GitOps, deployments are driven by committing declarative configuration into 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 is D.
