20+ practice questions focused on Cloud Native Application Delivery — one of the most tested topics on the Kubernetes and Cloud Native Associate KCNA exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Cloud Native Application Delivery PracticeRefer to the exhibit. The deployment myapp is updated from image myapp:1.0 to myapp:2.0. During the rollout, what is the maximum number of pods that will be unavailable at any given time?
Explanation: The deployment uses a RollingUpdate strategy configured with maxUnavailable=0 (as shown in the exhibit), meaning that during the update, no existing pods are terminated until new pods are ready. This ensures that the desired number of replicas is always maintained, resulting in zero unavailable pods at all times.
In Flux CD, which component is responsible for reconciling the cluster state with the source of truth defined in a Git repository?
Explanation: In Flux, the Kustomize controller is responsible for reconciling the cluster state with the desired state defined in a Git repository. It takes the artifacts fetched by the Source controller and applies Kustomize overlays to ensure the cluster matches the declared configuration. The Source controller only retrieves the source artifacts, not reconciliation.
A team is using Kustomize to manage configurations for different environments. They want to create a variant of a base deployment that uses a different number of replicas. Which Kustomize feature should they use?
Explanation: Kustomize uses overlays to customize bases for different environments. Patches are used to modify specific fields. Option B (Patches) is correct for changing replicas. Option A (Generators) creates ConfigMaps/Secrets. Option C (Bases) is the common configuration. Option D (Components) is a newer feature for reusable pieces.
Which deployment strategy is characterized by gradually shifting traffic from an old version to a new version of an application, often requiring a service mesh or ingress controller to manage traffic splitting?
Explanation: A canary deployment gradually shifts traffic from the old version to the new version, allowing monitoring before full rollout. This strategy typically requires a service mesh or ingress controller to manage traffic splitting. Option A (Rolling update) replaces pods incrementally but does not split traffic; it updates instances one by one. Option C (Blue-green deployment) switches traffic entirely between two identical environments (blue and green). Option D (Recreate) kills all old pods before creating new ones, causing downtime.
According to DORA metrics, which metric measures the percentage of deployments that fail in production?
Explanation: Change Failure Rate is the percentage of deployments causing a failure in production. Option A is correct. Option B (Mean Time to Restore) measures how long it takes to recover from a failure. Option C (Deployment Frequency) measures how often deployments occur. Option D (Lead Time for Changes) measures time from commit to production.
