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.

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.

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.

Progressive deliveryis a GitOps pattern used to release software gradually, reducing risks associated with deploying new versions. Techniques such as canary releases, feature flags, and blue-green deployments allow teams to incrementally roll out changes, validate functionality with subsets of users, and minimize potential disruptions.

“Progressive delivery builds on continuous delivery by enabling safer, incremental rollouts. This pattern reduces risk, improves reliability, enhances user experience, and allows for validation of features with a portion of users before wider release.”

Therefore, progressive delivery is useful inmultiple scenarios(not just one-time deployments or small teams), making optionCcorrect.
