Question 1

Which requirement of the GitOps principle declares that Desired State must be versioned?

AThe Desired State must not be publicly accessible.

BThe State Store must retain a complete version history.

CYou must use Git in order to be compliant with this principle.

DThe Desired State must be publicly accessible.

Answer : B

One of the GitOps principles is Versioned and Immutable, which requires that the Desired State is stored in a system that maintains a complete version history. This allows for auditing, traceability, and rollback.

''The Desired State must be stored in a versioned, immutable system. The State Store must retain a complete version history so changes can be audited and previous states can be restored.''

Thus, the correct answer is B.

Question 2

Which GitOps tool has the option for a push-based reconciliation model?

AArgoCD

BFlagger

CFlux

DArgo Workflows

Answer : A

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.

Question 3

Which of the following statements accurately describes the role of GitOps in progressive delivery?

AGitOps requires end users to manually shift traffic for progressive delivery.

BGitOps allows end users to perform progressive delivery automatically without manually shifting traffic.

CGitOps only works with manual progressive delivery without any automation.

DGitOps does not allow end users to perform progressive delivery automatically, only manually.

Answer : B

Progressive delivery is a GitOps pattern that incrementally rolls out application updates, using methods like canary releases, feature flags, and blue-green deployments. GitOps enhances this by ensuring the rollout is automated and declaratively managed through Git, removing the need for manual traffic switching.

''GitOps enables progressive delivery by declaratively managing rollout strategies such as canary or blue-green deployments. These strategies are applied automatically by controllers, without requiring manual traffic switching.''

Thus, the correct answer is B.

Question 4

In the context of GitOps, what does Continuous mean?

AReconciliation happens only during instantiation.

BReconciliation must happen instantaneously.

CReconciliation continues to happen.

DReconciliation only happens once.

Answer : C

One of the four core GitOps principles is that the system must be Continuously Reconciled. This means reconciliation is not a one-time or on-demand process but happens constantly in the background, ensuring the actual system state remains aligned with the declared desired state.

''GitOps requires that reconciliation is continuous. Software agents continuously compare actual state against desired state and automatically reconcile differences.''

Thus, the correct answer is C.

===========

Question 5

What does Pulled Automatically refer to?

AA GET request to a relational database.

BIt always refers to Git pull.

CWebhooks informing the system about new commits.

DAccessing the Desired State from the State Store.

Answer : D

The Pulled Automatically GitOps principle refers to the way software agents continuously access the Desired State stored 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 is D.

===========

Question 6

Which of these is an advantage of using a declarative configuration for your Desired State?

ADeclarative configuration allows you to execute code locally more efficiently to make desired changes to your running system.

BUsing widely adopted community tools for reconciling actual state is less work than maintaining custom imperative scripts.

CDeclarative configuration helps you include dynamic scripting that guides an application through a step-by-step process.

DDeclarative configuration lets you specify complex if/else logic within custom code.

Answer : B

Declarative configuration describes what the system should look like, not how to achieve it. This enables the use of standard reconciliation tools (like ArgoCD or Flux) to manage the system automatically, removing the burden of writing and maintaining imperative scripts.

''Declarative configuration enables systems to be managed by generic reconciliation tools rather than bespoke scripts, reducing operational overhead and increasing reliability.''

Thus, the correct answer is B.

===========

Question 7

Why is the feedback loop important for reconciliation?

ATo determine if a reconciliation is needed and whether a sync should be partial or complete.

BTo analyze state-sync logging information and perform a sync.

CTo trigger an alert if a change is detected, and log the event to the log aggregation service.

DFeedback loop is not important for reconciliation.

Answer : A

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.
