Which statement describes Blue-Green deployments?
A
Explanation:
Blue-Green deployments are a progressive delivery pattern where two environments exist: Blue
(current version) and Green (new version). The new version is deployed in parallel, and once
validated, traffic is switched over from Blue to Green.
“Blue-Green deployments provide zero-downtime releases by running two production environments:
one active and one idle. A new version is deployed to the idle environment, tested, and when ready,
traffic is switched to it.”
Thus, the correct description is A.

In a GitOps framework, what distinct advantage does Configuration as Code (CaC) provide in
comparison to traditional infrastructure management approaches?
B
Explanation:
Configuration as Code (CaC) in GitOps ensures that infrastructure and application definitions are
stored in Git, version-controlled, and immutable. Unlike traditional approaches (manual changes,
scripts, mutable infrastructure), GitOps uses CaC for immutable infrastructure deployments,
guaranteeing reproducibility and environment consistency.
“Configuration as Code ensures that system configuration is stored declaratively in version control.
This allows immutable deployments, reproducibility, consistency across environments, and prevents
ad-hoc manual changes.”
Thus, the distinct advantage is immutable deployments and consistent environments, making B
correct.

A GitOps-managed Software System includes which of the following?
B
Explanation:
A GitOps-managed software system is defined as one or more runtime environments whose
resources are managed declaratively via GitOps practices.
“A GitOps-managed software system includes one or more runtime environments, such as clusters,
where resources are under management. The desired state of these resources is declared in Git and
reconciled continuously.”
Thus, the correct option is B.

===========
In GitOps, what is a pull-based approach?
D
Explanation:
In GitOps, pull-based deployment is fundamental. Instead of pushing changes into a cluster, GitOps
agents running inside the cluster continuously pull from Git to reconcile desired state.
“GitOps uses a pull-based model: agents inside the cluster continuously poll the Git repository for
desired state changes. If changes are found, they reconcile the live system automatically to match
the declared state.”
This ensures secure, automated, and consistent deployments.
Thus, D is correct.

A GitOps project wants to leverage both ArgoCD and Flux for a deployment. Can ArgoCD and Flux be
used in conjunction?
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 is C.

===========
You are working on a GitOps project and have made some changes to the cluster using kubectl. What
is the recommended approach to ensure that your changes are continuously reconciled?
B
Explanation:
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.
Reference: GitOps Principles (CNCF GitOps Working Group), Drift and Reconciliation Practices.
===========
In the context of GitOps, what source of truth guides the continuous deployment process?
A
Explanation:
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.
Reference: GitOps Terminology (CNCF GitOps Working Group).
===========
Why is the feedback loop important for reconciliation?
A
Explanation:
The feedback loop is critical in GitOps reconciliation. It continuously monitors the system’s actual
state and compares it to the desired state. This loop determines when reconciliation is required and
whether a full or partial synchronization is necessary.
“The feedback loop in reconciliation continuously observes the actual state. It determines if
reconciliation is required, and informs whether to perform a partial or full sync to align with the
declared desired state.”
Thus, the correct answer is A.
Reference: GitOps Related Practices (CNCF GitOps Working Group), Reconciliation Feedback Loops.
Which of these Git commands will enact a rollback of the configuration to a previous commit?
B
Explanation:
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.
Reference: GitOps Tooling (CNCF GitOps Working Group).
===========
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?
C
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 is C: Roll back to the previous working version.
