20+ practice questions focused on Application Deployment And Lifecycle — one of the most tested topics on the Red Hat Certified OpenShift Administrator (EX280, OpenShift Container Platform 4.14+) (EX280) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Application Deployment And Lifecycle PracticeAn administrator needs to deploy a packaged Helm chart onto an OpenShift 4.14 cluster from a private Helm repository. Which oc command should be used to install the chart while securely managing repository credentials?
Explanation: The 'oc helm' CLI wrapper does not exist natively as 'oc helm'; however, Helm v3 integrates directly with Kubernetes/OpenShift clusters using standard 'helm install' or by configuring Helm repository add commands before installing. Alternatively, using 'oc apply' with pre-rendered manifests or 'helm install' directly against the cluster context is standard. Let's look at the standard Helm workflow used in OpenShift contexts.
How do you define a command to run immediately before a container starts, such as a database migration?
Explanation: A 'pre' lifecycle hook in the Deployment strategy allows you to run commands before the deployment starts.
An OpenShift administrator needs to trigger a rollback of a Deployment to its previous working revision after a failed update. Which oc command should be used?
Explanation: The oc rollout undo command reverts a deployment back to a previous revision in the rollout history.
A developer has created a Kustomization file that applies a namespace prefix and some patches to base Kubernetes manifests. How can the developer apply these manifests to an OpenShift cluster using standard oc tooling without installing standalone Kustomize?
Explanation: The oc apply command includes built-in support for Kustomize via the -k flag, which processes a directory containing a kustomization.yaml file.
A DeploymentConfig in OpenShift has a Rolling strategy defined. Which parameter in the strategy configuration controls the maximum number of pods that can be created above the desired replica count during the update?
Explanation: maxSurge controls how many pods can be scheduled above the desired number of pods during a rolling update.
