The reconciliation loop is a fundamental GitOps principle. It continuously compares the desired state (stored in Git) with the actual 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 is C.

In GitOps, rollback is performed by reverting the system's Desired State stored in Git. This is done with the git revert command, 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 is B: git revert.

===========

GitOps is not a replacement for DevOps. Instead, it is an evolution and practical implementation of DevOps principles, using Git as the single source of truth and continuous reconciliation as the operational model.

''GitOps builds on the foundation of DevOps by providing a framework to put its principles into practice. It leverages Git and declarative reconciliation to realize DevOps goals.''

Thus, the best description of the relationship is B.

In GitOps, Git is the single source of truth. If changes are made manually in the cluster (via kubectl), those changes will drift from the desired state in Git. To ensure consistency, the correct approach is to update the Git repository (Desired State store) so that the reconciler can continuously apply and maintain those changes.

''The desired state must always be declared in Git. Manual changes in the cluster will be overwritten by reconciliation unless they are committed to the Git repository.''

Thus, the correct answer is B.

===========

In GitOps, systems are defined declaratively. This means that the desired state is described in Git, while the steps to achieve it are not explicitly defined. Instead, reconciliation agents interpret the declarative definition and automatically apply changes as needed.

''A declaratively defined system specifies only the desired state. It does not describe the sequence of steps required to reach that state. The reconciliation process ensures the system converges to the declared state automatically.''

Therefore, the correct answer is C: Only the Desired State.
