Question 1

How can you achieve the declarative GitOps principle in managing infrastructure and applications?

ABy using imperative scripting languages to automate infrastructure changes.

BBy manually making ad-hoc configuration changes directly in the production environment.

CBy periodically creating manual backups of your infrastructure configurations.

DBy defining and maintaining infrastructure and application configurations declaratively in a version-controlled system.

Answer : D

The first GitOps principle is Declarative 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.

Question 2

In the context of GitOps, what source of truth guides the continuous deployment process?

ADesired State

BDynamic State

CFleeting State

DCurrent State

Answer : A

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.

===========

Question 3

You are packaging a complex application to deploy to multiple Kubernetes clusters using GitOps. Which of the following would be a suitable solution for this process?

ACreating a Helm chart to define the application's configuration and dependencies.

BConfiguring a CI/CD pipeline to build and deploy the application to the Kubernetes cluster automatically.

CCreating a well-formatted script to deploy the application to the Kubernetes cluster.

DWriting a Dockerfile to build a container image of the application and configuration.

Answer : A

Helm is a Kubernetes package manager widely used in GitOps for packaging, configuring, and deploying complex applications. Helm charts bundle configuration, dependencies, and Kubernetes manifests into reusable, declarative packages that can be applied across multiple clusters.

''Helm charts provide a way to package Kubernetes applications, defining configuration and dependencies declaratively. This allows consistent deployment across clusters in GitOps workflows.''

Thus, the correct answer is A.

===========

Question 4

You want to deploy an application using GitOps. Which of the following steps should be included in the deployment process?

ARunning a script in CI to deploy the application.

BSkipping the deployment process and directly running the application code.

CManually copying the application code to the production server.

DCommitting the deployment configuration to a Git repository or similar State Store.

Answer : D

In GitOps, deployments are driven by committing declarative configuration into a Git repository (the State Store). From there, agents reconcile the actual environment to match the desired state, making deployments reproducible and auditable.

''To deploy in GitOps, commit the declarative configuration into version control. The reconciler ensures the runtime environment converges to the declared state.''

Thus, the correct answer is D.

Question 5

Would you implement DevSecOps culture in CI/CD pipelines?

ANo, because CI/CD systems are totally secure by design.

BNo, DevSecOps focuses only on security outside of CI/CD pipelines.

CNo, because CI/CD systems are incompatible with the DevSecOps culture.

DYes, DevSecOps is essential for CI/CD pipelines. It helps build software without any security issues.

Answer : D

DevSecOps integrates security into the DevOps culture and CI/CD pipelines. Instead of treating security as an afterthought, DevSecOps ensures security checks, policies, and automated validations are embedded throughout the CI/CD process.

''DevSecOps emphasizes shifting security left, integrating security testing, validation, and compliance into every stage of the CI/CD pipeline. This ensures vulnerabilities are detected early and software is delivered securely.''

Thus, D is correct: DevSecOps culture is essential for CI/CD pipelines to ensure security is baked into software delivery.

===========

Question 6

In GitOps, which option describes State Store management?

AStoring state information in a relational database.

BStoring state information in a centralized database.

CStoring state information in a distributed file system.

DStoring state information in a version control system.

Answer : D

The State Store is typically implemented using a version control system (VCS) such as Git. This ensures that the system's state is auditable, versioned, and immutable. Other systems like databases or distributed file systems do not meet the immutability and versioning requirements of GitOps.

''In GitOps, the desired state must be stored in a version control system. This serves as the State Store, providing a complete, immutable, and auditable history of changes.''

Thus, the correct answer is D: version control system.

Question 7

You want to route alerts from Prometheus to Slack in your GitOps workflow. Which tool can you use to achieve this?

AAlertmanager

BSlack

CPrometheus

DJenkins X

Answer : A

Prometheus is commonly used in GitOps for monitoring. Alertmanager is the tool integrated with Prometheus to handle alert routing. It supports sending alerts to external systems such as Slack, PagerDuty, or email.

''Prometheus generates alerts, which are routed and managed by Alertmanager. Alertmanager can integrate with messaging tools like Slack to deliver alerts in real time.''

Thus, the correct answer is A: Alertmanager.
