CGOA Exam Dumps - Linux Foundation DevOps and Site Reliability Questions and Answers

ACanary Deploymentgradually introduces a new application version to a small subset of users before expanding to the full user base. This pattern allows testing and validation in production while reducing risk.

“Canary deployments progressively roll out changes to a small group of users, monitoring for issues before routing all traffic to the new version. This gradual shift minimizes risk and ensures safer releases.”

Thus, the correct answer isB.

The process of keeping theactual statein sync with thedesired stateis calledReconciliation. 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 isA: Reconciliation.

The GitOps principle ofVersioned and Immutablerequires Desired State to be stored in a way that enforcesimmutability and versioning. This ensures every change is recorded, auditable, and reversible.

“Desired state must be kept in an immutable, version-controlled system. This guarantees a full history of changes and enables safe rollbacks.”

Thus, the correct answer isD.

Kustomizeis a Kubernetes-native configuration management tool that allows manifest customization without modifying the original YAML files. It uses overlays and patches to adapt configurations for different environments.

“Kustomize provides a declarative way to customize Kubernetes manifests by applying patches and overlays. This allows managing multiple environments without duplicating manifest files.”

Thus, the correct answer isD.

In GitOps, deployments are driven bycommitting declarative configurationinto 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 isD.

Blue-Green deployments are aprogressive delivery patternwhere 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 isA.

One of the four fundamental GitOps principles isVersioned and Immutable. This means that the entire system’s desired state must be stored in a Git repository with version control. Each change must be represented as a commit, and Git’s immutability guarantees a reliable, auditable history of how the system evolved.

“The desired state is stored in a version control system. The record of truth is stored in an immutable history, and changes can be audited and reverted if necessary. This guarantees that the system’s configuration is versioned, immutable, and traceable.”

Thus,configuration and infrastructure must be version-controlled and immutable, never changed directly in production.

In GitOps, thedesired stateis stored in Git. Manual updates applied directly to the cluster (via kubectl or APIs) change theactual statewithout updating Git. This introducesdriftbetween actual and desired state.

“Manual changes to the runtime environment cause the actual state to diverge from the desired state stored in Git. This drift must be detected and reconciled automatically.”

Thus, the correct answer isC.
