The process of keeping the actual state in sync with the desired state is called Reconciliation. GitOps

controllers (e.g., ArgoCD, Flux) continuously reconcile system resources to match what is declared in

Git.

“Reconciliation is the process by which agents compare the actual system state to the desired state

and automatically make changes to converge them.”

Thus, the correct answer is A: Reconciliation.

===========

The Desired State in GitOps is the declarative specification of how the system should behave. It is

stored in Git and serves as the reference point for reconciliation against the actual state.

“The desired state is a complete specification of the system stored in Git. It acts as the blueprint from

which the actual state is continuously reconciled, ensuring the system remains consistent and

reproducible.”

Thus, the primary purpose of Desired State is to act as a blueprint to recreate and ensure consistency

of the system.

===========

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.

===========

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.

Principles documents.

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.
